ArtWatch at Thirty, Part II: The Artful Promotion of the World’s Worst Restorations

15 APRIL 2023. MICHAEL DALEY WRITES:

In Part I we set the 1980-1994 cleaning of Michelangelo’s Sistine Chapel frescoes in the era’s ambitiously experimental and accident-prone restorations. Here, we examine the art-historically untenable scholarship that arose when Michelangelo’s debilitated frescoes were endorsed as if constituting revelations that merited a rewritten history of art. Three decades on, identifying and examining the polished art-political stratagems that draw so many scholars and art critics into supporting egregiously destructive restorations remains a matter of professional urgency.

Above, Fig. 1, Top: National Geographic’s iconic photo-record of the Sistine Chapel ceiling which captured the last moments of the most acclaimed late stage of Michelangelo’s painting, including his The Crucifixion of Haman, the Prophet Jonah, and the Libyan Sibyl. Above, the post-cleaning, LED-lit chapel. When unveiled in 1512, the then brilliantly lit and shaded figures set in deep architectural spaces were eulogised for having made surfaces which physically advanced towards the viewer recede optically through Michelangelo’s powers of design and unprecedented deployment of lights and shades. At the time, no one spoke of Michelangelo’s colour – “brilliant” or otherwise.

TWIN AND CROSS-LINKED ASSAULTS ON A CRITIC

On 8 October 1987, halfway through the cleaning of the Sistine Chapel Ceiling, the restoration’s leading scholarly critic, Professor James Beck, Chairman of Columbia University’s Art History and Archaeology Department, was branded the “most culpable of the critics” by Sir John Pope-Hennessy in the New York Review of Books (“Storm Over the Sistine Ceiling”). Two months later, that attack was followed by another in the December Apollo magazine by Kathleen Weil-Garris Brandt (“Twenty-five Questions about Michelangelo’s Sistine Ceiling”). Like Pope-Hennessy, Brandt was a professor of Renaissance art at New York University’s post-graduate art history school, The Institute of Fine Arts (which incorporates a Samuel H. Kress Program-sponsored conservation department), and she was considered a long-standing friend by him.

Brandt characterised the restoration’s critics as “a tiny, heterogenous and vociferous cadre”. She likened their arguments to “the wild cries of some ferocious mutant of Chicken Little” and added “Many believe that the critics, like that benighted bird, were misunderstanding insufficient evidence, to draw mistaken conclusions to the alarm and detriment of the neighbours.” She conceded the issue “is a serious one” but only the better to sting: “Are the critics merely opportunists, bodysurfing in a wave of publicity they would never otherwise have enjoyed?” In his 2016 memoir, Michelangelo and I, Gianluigi Colalucci, the restorer/co-director of the Sistine Chapel restorations, described Brandt as “sweet and gentle in appearance but with a character of steel” who, having “obtained her own office in the museum complex”, had “put just about everybody under pressure with her inflexible activity”.

“THINGS ARE NOT AS YOU THINK”

There were degrees of hypocrisy in both attacks. Pope-Hennessy’s charge of professional culpability had followed his invitation to Beck to serve on a Metropolitan Museum Advisory Committee. As Colalucci would later disclose, Brandt’s denigration was not made as the self-effacing and disinterested scholar she had implied in Apollo“Like many Renaissance scholars, I have held a kind of informal watching brief for the cleaning operation since its inception in 1981 [sic] and I talk on the subject with groups and individuals of all kinds.” Formally speaking, Brandt had two dogs in this fight. First, she had obtained her Vatican office as the official spokesman on “Scholarly and General information” for Arts and Communications Counsellors, a division of the New York Public Relations firm Ruder and Finn Inc. which had been retained by the Vatican to handle the restoration crisis. Second, she was a member of a shadowy, secretive scientific advisory committee the Vatican had set up, ostensibly, to monitor the controversial restoration. On learning of that committee, Colalucci threatened to resign but was dissuaded by his restoration co-director, Fabrizio Mancinelli, who urged him to calm down because: “You’ll see that things are not as you think…” In due course, Colalucci recalled, “we were given to understand that the findings were positive”.

As will be shown in Part III, the ploy of an institutionally self-appointed, supposedly invigilating but intended exonerating body, had been honed at the National Gallery in 1947 and 1967. Given the importance of the greatest art, whenever major restorations are started, they must, of political necessity, be defended unequivocally for the duration and at length thereafter, for fear of triggering institutional melt-downs. When a restoration of sacred art in a sacred place is funded in advance by a foreign corporation in a commercial exchange for film and photography rights, any admission of error becomes doubly inconceivable. Little surprise therefore that, as Colalucci disclosed, the Vatican’s own scientific advisory committee remained in place as a supportive “working group” throughout the entire restoration of Michelangelo’s Sistine Chapel frescoes. Headed by André Chastel, this group’s members, in addition to Brandt, were:

“Carlo Bertelli of Lausanne University, initiator of the restoration of Leonardo’s Last Supper executed by Pinin Brambilla [See: The Perpetual Restoration of Leonardo’s Last Supper, Part I: The Law of Diminishing Returns]; Pierluigi De Vecchi, an expert on Michelangelo; Sydney J. Freedburg from Washington; Giovanni Urban[i] former director ICR [the Istituto Centrale di Restauro]; Luitpold Frommell and Matthias Winner, directors of the Bibliotecca Hertziana in Rome; Umberto Baldini, director of the ICR [and head of the Brancacci Chapel restoration]; Michael Hirst, an expert on Michelangelo’s drawings; John Shearman, an expert on Raphael and the Sistine Chapel…The restorers were Alfio Del Serra from Florence…and Paul Schwartzbaum from New York, head of the ICCROM school and projects in Rome. Norbert Baer from New York University was the only chemist.”

THE SAMUEL H. KRESS FOUNDATION INTERVENTION

Colalucci aired a secondary grievance concerning the advisory committee in 2016: “By express desire of Chastel and the other members, we were not allowed to inform the press of the work of this group of experts, even though it would have been of great benefit to us because” [the quasi-invigilators] “wished to keep a low profile and avoid the attention of the already overly excited public opinion”. However, “Shortly afterwards, Marilyn Perry, the pleasant and dynamic president of the Kress Foundation, set up another working group, this time consisting almost exclusively of restorers on her own initiative.”

“The members were Mario Modestini, the foremost restorer in America; John Brealey, director of the restoration department of the Metropolitan Museum of Art in New York; the young Dianne Dwyer, then assistant to John Brealey [see Fig. 11 below]; Andrea Rothe, director of the restoration department of the J. P. Getty Museum in Malibu; David Bull, director of the restoration department of the National Gallery in Washington [see Figs. 2 and 3 below]; and Leonetto Tintori, a highly skilled restorer from Florence [see Fig. 3 below].

“The group’s task was to monitor our work, give advice and put forward criticisms. The [single] meeting was very fruitful and ended positively with a report drawn up [by] the members of the group aimed in particular at public opinion in the United States.”

The resulting open letter from this committee to the American press executed its expressly intended effect to perfection. In April 1987, Time’s art critic, Robert Hughes, claimed:

“…most experts on Renaissance art, and on Michelangelo in particular, strongly endorse it and reject out of hand the anti’s allegation of haste or insufficient study…Last week a further vote of confidence came from the Samuel H. Kress Foundation, a long-established non-profit organisation concerned with the care and preservation of Italian art. Six of the world’s leading conservators… reported in an open letter that the ‘new freshness of the colours and the clarity of the forms on the Sistine Ceiling, totally in keeping with 16th century Italian painting, affirm the full majesty and splendor of Michelangelo’s creation’”

John Russell reported in the New York Times:

“An international Group of leading conservators of Italian paintings has given its unanimous and strongly enthusiastic approval to the current restoration of Michelangelo’s frescoes in the Sistine Chapel in Rome…Though not intended as a riposte to recent criticism of the restoration the report could be said to rebut the attacks that have been made upon it. Among those who have opposed the restoration are Prof. James Beck of Columbia, Alexander Eliot, formerly of Time Inc. and a group of 14 American artists who asked the Pope to halt the work…”

If Bull had simply removed a discoloured film of varnish, the previously discernible tonal values would have emerged enhanced – and not, as seen, diminished, compressed, and with a flattening of previously tangible forms. Such losses were Bull’s forte: when he restored Turner’s Rockets and Blue Lights (Fig. 3, below), one of the picture’s two distressed steamboats disappeared and its plume of once-black smoke was painted into a waterspout. (When that restorations-wrecked picture was sent to the UK on a tour, credulous British art critics took their lead from a Tate Gallery press release and gushingly proclaimed it “One of the stars of the show”.)

SUCKERED ART CRITICS

Where the Kress Committee’s open letter achieved immediate propagandistic effect, it took time for the claimed unanimity of its expert endorsement to dissolve. In a 28 April 2012 post we made the following (uncontested) disclosures:

“ArtWatch has been haunted for two decades by a nearly-but-not-made restoration disclosure. In the 1993 Beck/Daley account of the Nippon TV sponsored Sistine Chapel restoration (Art Restoration: The Culture, the Business and the Scandal), we reported that in the late 1980s Leonetto Tintori, the restorer of Masaccio’s Holy Trinity in the Santa Maria Novella, Florence [Fig. 3, above] and a member of the international committee that investigated the controversial cleaning, had urged the Sistine team privately to preserve what he termed ‘Michelangelo’s auxiliary techniques’ which in his view included oil painting as well as glue-based secco. What we had not been able to say was that Tintori (who died in 2000, aged 92) had prepared a dissenting minority report expressly opposing the radical and experimental cleaning method.

“Shortly before the press conference called to announce the committee’s findings, Tintori was persuaded by a (now-deceased) member [Fabrizio Mancinelli] of the Vatican not to go public with his views. He was assured that his judgement had been accepted and that what remained on the Sistine Chapel ceiling of Michelangelo’s finishing auxiliary secco painting would be protected during the cleaning. With a catastrophically embarrassing professional schism averted, the restoration continued and the rest of what Tintori judged to be Michelangelo’s own auxiliary and finishing stages of painting was eliminated. Without knowledge of Tintori’s highly expert dissenting professional testimony, the public was assured that despite intense and widespread opposition the cleaning had received unanimous expert endorsement. Critics of the restoration were left prey to disparagement and even vilification.”

Our 1993/2012 claims on the dissent within the international committee had been double-sourced by James Beck and the Florence-based art historian Richard Fremantle in conversations with Tintori (a member of ArtWatch). They became triple-sourced and document-backed on 8 June 2011 when the Titian expert and former director of the Warburg Institute, Professor Charles Hope, gave the following account when delivering the third James Beck Memorial Lecture (“The National Gallery Cleaning Controversy”) at the Society of Antiquaries, London:

“It would be unrealistic to suppose that those directly involved in the restoration would willingly concede that large areas of Michelangelo’s own work were removed. But even those who believe that the restorers did a good job ought to recognise that much of the controversy could have been avoided if a more careful assessment of the art-historical evidence had been carried out before the restoration began. But no serious investigation was made of the records of earlier restorations, the issues raised by Wilson were not addressed, and Vasari’s testimony was accepted as conclusive evidence that Michelangelo only used buon fresco, without any recognition of its problematic character (which was well understood in the nineteenth century) and without any discussion of the evidence of Armenini. In this context, one might also mention an article in the 1995 Revue de l’art by Leonetto Tintori, the most experienced restorer of Tuscan frescoes of his generation, who died in 2000 at the age of 92. Tintori was consulted about the desirability of restoring the ceiling, and I understand that he opposed it. The most important point in his article is that the technique supposedly used by Michelangelo on the ceiling, buon fresco alone, with only very small additions in secco, was entirely inconsistent with the practice of other painters in Tuscany, from Buffalmacco to Lippi and Sarto; and the same point was made by Eve Borsook [art historian and author of the 1960 and 1980 The Mural Painters of Italy] in the same journal. Tintori ended his article by deploring the modern practice of ever deeper cleaning, concluding, ‘This new orientation aimed at the total restitution of the original paint has had the paradoxical effect that the appearance of pure authenticity has become increasingly rare.’ Given his membership of the [Kress-assembled] committee that recommended, apparently against his own advice, the restoration of the ceiling, he could hardly have attacked the results explicitly, but it cannot be by chance that he chose to say what he did, a year after the publication of the [Vatican’s] final restoration report.

WHO HAD KNOWN OF TINTORI’S DISSENT?

In his 2016 memoir, Colalucci made no mention of Tintori’s opposition or his 1995 Revue de l’art views on the destructiveness of the Sistine Chapel restorations – his sole reference to the opposing restorer came in his above-cited composition of the Kress committee. Presumably, all other members of the working group – Modestini; Brealey; Dwyer [-Modestini]; Rothe and Bull had known of his opposition, as had Mancinelli. Perhaps Marilyn Perry and Colalucci had not known, but, certainly, Robert Hughes, John Russell, and very many other journalists were duped. Brandt gave no hint of Tintori’s opposition in Apollo but she stopped fractionally short of claiming unanimity:

“Everyone agrees with David Bull, Head of Paintings Conservation at Washington’s National Gallery of Art, that ‘the work being done on the frescoes should be meticulously watched, examined and questioned… (Fresco conservators seem not to be disturbed by the cleaning.)”

POPE-HENNESSY’S ATTACK ON BECK

When dubbing Beck the most culpable scholar/critic, Pope-Hennessy detached himself from his professional obligations:

“If you are an art historian, it is essential to free yourself from the fetters of your profession. The Sistine Ceiling is no more the property of art historians than the Ninth Symphony is the property of musicologists.”

The analogy was perversely inapt: in the Sistine Chapel, two recently appointed young officials – an art historian/curator and a quasi-scientific restorer – were rewriting a score they had ignorantly/wilfully misread in defiance of their predecessors’ views and reports and they were demanding that musical history be re-written to sanctify their systematic adulterations.

Pope-Hennessy was not alone in standing on such treacherous ground – he was running with a pack. His denunciation of Beck was made in a review of the 1986 book The Sistine Chapel: The Art, the History, and the Restoration (- published in the UK as The Sistine Chapel: Michelangelo Rediscovered). The book carried accounts from the three principal Vatican agents of the restoration: Professor Carlo Pietrangeli (Director General of the Vatican Museums); Dr Fabrizio Mancinelli (Curator of the Vatican Museums’ Byzantine, Medieval and Modern collections); and Gianluigi Colalucci (the Vatican’s Chief Restorer) – the latter two being the restoration’s co-directors. Their views were implicitly endorsed by accompanying scholarly essays from André Chastel, Pierluigi de Vecchi, Michael Hirst, John O’Malley, and John Shearman. The book was co-published by the Nippon Television Network Corporation which had sponsored the 1980-1994 restoration for $3million in exchange for all film and photography rights throughout each of the restoration’s three stages (the upper wall lunettes; the ceiling; and the Last Judgement altar wall) and for three years afterwards on each part.

INDEFENSIBLE METHODS

Pope-Hennessy appreciated that the restoration breached fundamental protocols by being conducted piecemeal on a narrow, enclosed platform when under intense film-set lighting that denied the restorers any means of appraising the actions and artistic effects of their radical, oven cleaner-like gelled cocktail of soda, ammonia, and detergents. (See Figs. 1 and 4.)

The cleaning paste, AB57, had been formulated to strip all historic organic materials from the plaster surface in two three-minute applications set twenty-four hours apart and removed each time with copious amounts of sponged water. The solvents-contaminated rinse water saturated the fresco plaster so completely that underdrawings on a lower plaster layer became visible. Empty assurances were given that a new air-conditioning system would protect the newly exposed bare plaster surfaces from the Chapel’s notoriously high levels of dirt, humidity, and fluctuating temperatures. Reports later emerged of secret night-time removals of white powder accumulations on the ceiling frescoes. By 2013 the ceiling had been lit to brighter and more colourful effect with powerful LED lights, when the chief defence of the restorers had been their supposed recovery of originally brilliant colours. See “The Twilight of a God: Virtual Reality in the Vatican” where we asked:

“Given this recent history, might Prof. Brandt – or any of the restoration’s supporters at that time – ever have imagined that within a couple of decades the Vatican would conclude that the chromatically brilliant ‘New Michelangelo’ would require artificial lighting ten times more powerful than that installed at the time of the restoration?”

In 2016, Colalucci blamed the chapel’s initially too-powerful levels of artificial lighting for the cleaning controversy itself:

“None of us had realized that after cleaning, these frescoes needed minimal lighting in order to be seen correctly. We should have considered the fact that, having been painted to be seen solely in light from the windows or candles and torches, they would look wrong in very brights lights such as television crews use.”

Despite the claim that the restoration had recovered an original intense chromaticism in Michelangelo’s painting that required low levels of lighting, the apparently natural light entering through the chapel’s windows was subsequently turbo-charged:

“…in the end the entire lighting system was revolutionized and moved outside with quartz lamps behind the window panes in accordance with a project devised by the technical department for a combination of natural and artificial light. Today with the new [LED] technologies, the Vatican Museums have installed a new lighting system with good results.”

THE STILL-UNSOLVED ATMOSPHERIC POLLUTION PROBLEM

On 10 January 2013 we reported:

“It is now clear that having first engineered a needless artistic calamity, the Vatican authorities have additionally contrived a situation in which the already adulterated remains of Michelangelo’s Sistine Chapel frescoes are presently in grave physical peril. On January 2nd 2012 Art Daily carried an Agence France-Presse report on the panic that has beset the Vatican authorities over the present and worsening environmental threat to the Chapel’s frescoes:

“The Vatican Museums’ chief warned that dust and polluting agents brought into the Sistine Chapel by thousands of tourists every-day risk one day endangering its priceless artworks. Antonio Paolucci told the newspaper La Repubblica in comments published last Thursday that in order to preserve Michelangelo’s Last Judgment and the other treasures in the Sistine Chapel, new tools to control temperature and humidity must be studied and implemented. Between 15,000 and 20,000 people a day, or over 4 million a year, visit the chapel where popes get elected, to admire its frescoes, floor mosaics and paintings. ‘In this chapel people often invoke the Holy Spirit. But the people who fill this room every day aren’t pure spirits,’ Paolucci told the newspaper. ‘Such a crowd… emanates sweat, breath, carbon dioxide, all sorts of dust,’ he said. ‘This deadly combination is moved around by winds and ends up on the walls, meaning on the artwork.’ Paolucci said better tools were necessary to avoid ‘serious damage’ to the chapel… The Sistine Chapel, featuring works by Michelangelo, Botticelli and Perugino, underwent a massive restoration that ended in the late 1990s. The restoration was controversial because some critics said the refurbishing made the colours brighter than originally intended.”

POPE-HENNESSY’S MANIFEST AMBIVALENCE

Without addressing the invasive actions of AB57 – the use of which had been condemned by restorers, scientists, artists, and art historians – or the abnormal film lighting – Pope-Hennessy did acknowledge some of their artistically disruptive consequences:

“On the other hand, it must be recognised that the effect made by any section of the fresco is contingent on the cleaning not only of that section but of the areas contiguous to it. The figure of God the Father in the Creation of the World could be cleaned faultlessly, but it would appear less dominant if the equation between the figure and the fictive moulding around it were disturbed. This has occurred in the first half of the ceiling…where the upper strip of the [fictive architectural] framing is now too light. If this happened in the second half of the ceiling, there would be protests that the Genesis scenes had been diminished or spoiled. The present width of the scaffolding is the equivalent roughly of one bay of the ceiling, and it is extremely difficult when standing on it to judge the relationship of the part of the ceiling that is within touching distance to the cleaned part beyond. I have repeatedly wondered whether it would not be prudent in the second half of the ceiling to employ a platform of double width, even at the cost of denying a larger area of the fresco to current visitors.” (Emphases added.)

Above, Fig. 4: The Sistine Chapel ceiling showing the restorers and film-makers’ platform approaching the most brilliant, deep-space final stages of Michelangelo’s painting.

“TO RESTORE OR NOT TO RESTORE” – COLALUCCI’S BREACH OF PROTOCOLS

Had Pope-Hennessy’s suggestion been made and accepted (thereby tacitly acknowledging an unsound seven-year long procedure) it would have had no effect. Colalucci had stipulated the pre-set, no variations, two three-minute AB57 applications precisely to prevent his restorers from making individual appraisals for fear of undermining his desired aesthetic homogeneity. As he put it in 2016: “I wanted to have every square centimetre under my control and was reluctant to expose others to the risk of failure or controversy.” We can now be clear that this restoration truly was one man’s folly. On his unwarranted and unfounded insistence that Michelangelo had not painted on the fresco surface, the restoration was reduced to the brutally simplistic and non-artistic goal of executing the most technically expeditious removal of all historic materials from the plaster surface – which, in truth, was to say, primarily, the last stages of Michelangelo’s own work. For this reason, even if the restorers had been able to compare the already cleaned fresco sections with the one being cleaned, they had no authority to depart from Colalucci’s twin, three-minutes AB57 applications procedure. Later, in self-exculpation at a Kress-organised conference in New York, Colalucci claimed that the heat and the brilliant film-set lighting had “fatigued the eyes” and made aesthetic appraisals impossible – when the decision to clean with AB57 had been taken before the deal with the Japanese film-makers had been struck.
On his own admission, Colalucci had sanctioned a procedure that breached the most fundamental restoration protocol of all – and one that had recently been stated by Professors Paolo and Laura Mora, the inventors of AB57 – that, at all times, the restorer and not the cleaning agent itself must assume responsibility for all the resulting changes of appearance in the work of art. The absence of declared support for the Sistine restorations by the Moras themselves is conspicuous. My (Leonardist) colleague, Jacques Franck, recalls – and may still possess – a 1980s Italian newspaper report in which it was claimed that the Moras had resigned from a Vatican committee because they had judged AB57 (which had been developed to remove traffic pollution from Rome’s marble buildings) unsuitable for Michelangelo’s frescoes. Had they been invited to serve on the Kress-assembled committee, along with Tintori – and if not, why not? Or on the Vatican’s own committee? Our researches had found a single enigmatic comment on the subject. In the Summer 1987 Art News (“Michelangelo Rediscovered”), M. Kirby Talley, Jr. wrote: “The decision to restore the Sistine frescoes was not taken lightly. ‘To restore, or not to restore, that’s the question you have to ask yourself every time you are confronted with a problem.’ cautioned Professor Laura Mora, restorer at the Istituto Centrale del Restauro and a leading authority on fresco conservation.” Talley continued: “This question was posed by the Vatican authorities, and the pros and cons were scrupulously weighed before the final go ahead was given”. No doubt they were, but the fact remains that contrary to the Kress-driven propaganda coup that may have turned Pope-Hennessy, three – and arguably, the top three – leading fresco authorities had not been on the scales. Brandt brought no clarification on the matter in Apollo with her gnomic observation “Fresco conservators seem not to be disturbed by the cleaning”.

SACRIFICING MICHELANGELO’S “COMMUNICATIVE POWER”

Above, Fig. 5, top: two engraved copies of the Libyan Sibyl, both of which showed the Sibyl’s left arm relieved by a tonally dark background; above, a detail of Michelangelo’s Libyan Sibyl before (left) and after (right) Colalucci’s cleaning and showing the profound and systematic losses of Michelangelo’s secco-extended tonal range of shading and aerial placements. As well as making broad-brush tonal adjustments, Michelangelo had – as Charles Heath Wilson had testified in the late nineteenth century (when very closely examining the ceiling from a special scaffolding) – also drawn secco revisions to contours and to many details such as hair and eyes. In the above photo-comparison, it can be seen that many lines which had clarified and reinforced details like the Sibyl’s thumb, lower jaw, the hair band, and the edges of the giant book, had all perished in Colalucci’s soda/ammonia/detergent double-washing. Further, Wilson had supplied an incontrovertible material/scientific proof that the secco painting was Michelangelo’s own: the secco painting had cracked as the plaster had cracked. The ceiling had begun cracking in Michelangelo’s own lifetime. Had the painting been applied centuries later by subsequent restorers, as the Vatican claimed on no evidence, it would have run into the cracks. It had not run into the cracks – but the world heard nothing of this: Wilson’s crucial, utterly subverting testimony on the secco painting had been air-brushed out by all players at the Vatican and, wittingly or unwittingly, by all of their art historical supporter/apologists.

For his part, Pope-Hennessy harboured and instanced futher (well-founded) aesthetic and historical anxieties:

“…you come in, as you have always done, through the little door under the Last Judgement and look up, speechless at the rebellious Jonah, the melancholy Jeremiah, and the Libyan Sibyl heroically supporting her colossal book [Fig. 5, above]. But about halfway down the chapel is a scaffolding resting on rails along the walls, covered with mustard-coloured fabric on which appear the shadows of ordinary mortals busily at work. [Fig. 4, above.] Beyond it you look towards the Zechariah, the Joel, and the Delphic Sibyl, suffused with light and seemingly the work of another, more lively, more decorative artist…Inevitably, judgement contains a strong subjective element, the more so as two kinds of verdict are involved, short-term judgement dominated by pleasure at the unwonted freshness of paint surface and long-term judgement in which one asks oneself whether the image has the same communicative power that it possessed before… Each time I go back to the chapel and sit, as I have so often sat, before the pitted surface of the Jeremiah, I feel concern that future generations may be denied an experience that raised the minds and formed the standards of so many earlier visitors. This is the basis of the claim of Beck and many others that the cleaning should be suspended at this point.” (Emphases added.)

Against all of which, he baldly insisted: “If there were the least reason to believe that the late frescoes would be overcleaned, this would be a valid view. But there is no evidence of overcleaning in the restored section of the chapel and there is no reason to suppose that the later frescoes will be treated less judiciously.”

THE WILFULLY DISREGARDED HISTORICAL VISUAL RECORD

On Pope-Hennesy’s own – albeit limited – admissions, there was every reason not to take the Vatican restorers’ methods on trust, not the least of these being the fact that, as any visually alert scholar should have appreciated, the many copies of the Ceiling made from Michelangelo’s day to our own, had all testified to his secco overpainting:

Above, Fig. 6: Top, left, the ink and wash copy of Michelangelo’s Sistine Ceiling figure Jonah, made between 1524 and 1534 by Giulio Clovio; top, right, a c. 1800 etched copy of Michelangelo’s Jonah by the Irish painter James Barry, R. A.; above, left, a detail of Michelangelo’s Jonah before Colalucci’s cleaning and showing the then surviving secco remains of the Clovio-copied dramatic shadow cast from the Prophet’s left foot; above, right, Jonah’s left foot after Colalucci’s elimination of the secco-enhanced shadows.

Disregarding all such historical visual testimony, the Vatican insisted that what had been understood since the 1512 unveiling to be Michelangelo’s own shadows, were arbitrary accumulations of soot trapped in “glue-varnishes” applied centuries later by successive restorers with sponges tied to thirty-feet long poles – poles of which, we established, no record existed and which, had they existed, would have stopped thirty-feet short of the ceiling. The phantom poles were summoned by Vatican officials in the absence – which we also established – of Vatican records of ceiling-high restoration scaffolding.

THE BOOK THAT WOULD HAVE BLOCKED THE SISTINE CHAPEL RESTORATION:

Above, Fig. 7: Left, the compendious 1990 book of historic copies of Michelangelo’s Sistine Chapel frescoes; centre, the book’s reproduction of Giulio Clovio’s Jonah drawing; right, the book’s reproduction of 19th century engravings (after lost copies) of the two lunettes Michelangelo had painted on the Chapel’s altar wall and would later destroy when preparing that wall for his Last Judgement.

Had the above book been published before 1980 and due consideration been given to Wilson’s account, a cleaning of the ceiling would have been stopped dead by the testimony of the above two images. The Clovio drawing alone constituted a proof positive that Michelangelo’s instantly-acclaimed lights and shadows had not only been present on the Ceiling but were also present on Michelangelo’s upper wall lunette frescoes – just as Colalucci’s Vatican restorer predecessors had reported. It did so because the two lunettes part-shown in its lower corners, were the very ones that Michelangelo destroyed to paint his Last Judgement. Thus, the sharply pronounced shadow that had been cast along the ground by Jonah’s left foot had been painted before any restorer had been near the frescoes. It could not, therefore, have been a freakishly artistic by-product of soot trapped within successive “glue varnishes” applied by restorers. Moreover, the glimpses of the shadows cast by Michelangelo’s lunette figures in Clovio were in turn confirmed by the etched copies of the two destroyed lunettes on the altar wall. Even the Clovio-recorded nude boy supporting Jonah’s name tablet had originally cast his own shadow on the wall before Michelangelo painted his Last Judgement.

Above, Fig. 8: The name tablet for the Prophet Zacheriastop, before cleaning: above, after cleaning.

THE ELEPHANT ON THE CEILING

Michelangelo had not been the first artist to depict cast shadows. What stunned his contemporaries had been the thunderous force of spatial illusionism within which his figures had realised an unprecedentedly vivid sculptural presence-in-space. It was precisely in the wake of the illusionistic shading’s evisceration that Pope-Hennessy had (correctly) noted that where the name tablets had previously been “firmly integrated in the [real and fictive] architecture of the chapel…they [now] read like supertitles in an opera house”see Fig. 8, above. To repeat: that tragically late-published book had shown beyond any dispute that there had been no break in the visual record of Michelangelo’s shadows from his day to ours – and, therefore, that the Vatican’s restorers had destroyed the finishing stages of Michelangelo’s own painting throughout the ceiling. In retrospect – and after all the account/demonstrations we have published (see, for example, Cutting Michelangelo Down to Size) – it might increasingly seem that this visually self-evident truth was a truth too big and too inconvenient in its implications ever to be ceded by the Vatican and the compliantly supportive art historical establishment it had garnered.

UNDERSTANDING POPE-HENNESSY’S SCHOLARLY BLANK CHEQUE

As a former director of both the Victoria and Albert Museum and the British Museum; a professor of art history at New York University’s post-graduate Institute of Fine Arts; and the very recently retired Chairman of European Paintings at the Metropolitan Museum of Art, Pope-Hennessy’s essay had effortless clout despite his self-subverting acknowledgements of both disturbing artistic results and – even – a wide distrust of the restoration among professionally sound peers. He opted to berate the critics while lauding the restorers, not on what they had done (on some of which he was critical) but on what he expected them to do next. Perhaps he had been privy to Mancinelli’s assurance to Tintori? He had certainly registered concern over of a group of cleaned Prophets and Sibyls:

“Optically, seen from the altar end of the chapel, they look a little smaller and less weighty than they did before. In the heads, a gain in definition is accompanied by a loss of ambiguity.”

Given that the visual arts work on and through their optical reception, how could Pope-Hennessy discount his own art historically informed, optically received, reading of diminished volumes and weights in Michelangelo’s figures? Perhaps he, like the art critics Hughes and Russell, had been swayed (or cowed) by the sheer authority of the supposedly unanimous Kress Foundation report? In any event, he wrote:

“…a gulf opened between those who adhered to the old concept of the ceiling and those who embraced the ceiling as it seemed originally to have been. The dispute was taken up in the American press, in largely polemical terms. There were demonstrations; and vociferous protests were made by both academic and non-figurative artists. The Vatican authorities went so far as to explain publicly, in two days of conferences in New York, the restoration program and the data on which it was based. Not unnaturally American criticism was reported throughout Italy, and had a disturbing, though not demoralizing, effect on the restorers involved. Arrangements, however, were made for a number of restorers of acknowledged excellence (three of them specialists in fresco decoration) to visit Rome, and they one and all endorsed the wisdom of what was being done.” (Emphases added.)

LEARNING TO LOOK

Aside from this explicit professional deference to a Higher Technical Authority in matters of aesthetic appraisal, other possible explanations for Pope-Hennessy’s stance emerged in his 1991 memoir, Learning to Look. This most distinguished scholar had a visual Achilles Heel – of time spent in an art school, he recalled “I disliked this too, and to this day I cannot draw.” Moreover, he had developed aversions to fellow art historians – and even (like Colalucci) to subjective judgements:

“One of the things about art history that I found puzzling from the first was that clever art historians (there were stupid ones too, of course, but a lot of them were really clever) should reach diametrically opposite conclusions on the basis of a tiny nucleus of evidence. The reason, so far as one could judge, was that the subjective element in art history was disproportionately large. If this were so, it was not only works of art that needed to be looked at in the original but art historians too, since their results were a projection of their personalities. So for some years, I made meeting art historians a secondary avocation.”

From the first, Pope-Hennessy had indeed made it his business to meet as many art historians as possible. When he left Balliol College, Oxford, with a second-class degree in history and an alumnus’s legendary “tranquil consciousness of an effortless superiority” (- in his case, specifically: “in the form of a self-confidence that sometimes verged on arrogance and a clear understanding of the difference between success and a succès d’estime”) he sold some inherited coconut islands off Borneo as income to be devoted “to travelling and to the preparation of a book” – and all this when, like Max Beerbohm’s Young Arnold Bennet, already having “a life plan in my mind.” During the Second World War he “found himself” in the Intelligence Department of the Air Ministry and there, for the first time, “met ordinary people” whom he considered “congenial and interesting”. In later life he expressed a preference for works of art over people of any kind:

“Objects mean more to me than people. It is not that I am frigid or reclusive, but that object-based relationships are more constant than human ones (they never change their nature and they do not pall).”

THE CHURNING “RAW MATERIAL” OF SCHOLARSHIP – AND A NEW SPECTATOR SPORT?

However, and despite his avowed attraction to the constancy of objects, as a self-made art historian, Pope-Hennessy came to welcome their radical alteration by restorers:

“People sometimes complain that there is nothing new to be said about Italian painting. They mean by this there are now monographs on many minor painters and that the works of great artists have been discussed in a large number of books. But the truth is that the raw material of Italian painting is in a constant state of flux. When paintings change through cleaning, our view of the artist who produced them changes as well.”

Like many of their scholarly peers, newspaper art critics have come to welcome the easy copy-generating potential of restorers’ alterations. In December 2022, Waldemar Januszczak of the Sunday Times, extolled the National Gallery’s controversially reconstructed Piero della Francesca Nativity (Fig. 9, above) and claimed that museums themselves now welcome “the inevitable brouhaha that follows any big restoration” because it “provokes interest and gets people through the door.” However, the art historian Giorgio Bonsanti deplored the intervention in IL GIORNALE DELL’ARTE and fears that such “controversies are destined not to subside but to remain and grow in future years, because the problem exists, and will remain evident to the millions of visitors to the National Gallery”. Scarcely less alarming to the Gallery must have been the Guardian critic, Jonathan Jones’, (earlier) assault on the repainted Nativity.

Jones had been the newspaper art critic of choice who was embedded within the Gallery’s conservation department during the restoration of its version of the Leonardo Virgin of the Rocks. The Evening Standard art critic, Brian Sewell, a student of Anthony Blunt at the Courtauld Institute, and a long-time scourge of National Gallery restorations, had been similarly co-opted within the restoration of Holbein’s The Ambassadors (Fig. 10, below). When so embedded, Jones predicted (wrongly) that “ArtWatch will attack the restoration”. On the Nativity, Januszczak similarly predicted: “There will be those, of course, who will howl at the changes – there always are.” In this case, at least three have now done so on the record – in addition to Jones and Bonsanti, in the March/April 2023 issue of the Jackdaw, its editor, David Lee (“Abbronzatura Solaire”), complained that aside from imposing complexions on the shepherds that are “more appropriate to Love Island than Bethlehem”, the Gallery has confounded a manifestly un-finished painting with a damaged finished painting.

Having previously studied the Nativity’s historic and restoration dossiers, we would add that this panel painting has likely suffered more accumulated restoration blunders than any other in the collection – with the possible exception, perhaps, of Giovanni Bellini’s Madonna of the Meadow. Both of those two pictures received disastrous “structural surgery” from a restorer (Richard D. Buck) who had been hired and brought over from America in 1948 by the National Gallery’s Director, Sir Philip Hendy, to introduce supposedly advanced conservation methods. Januszczak, who defends the Nativity’s recent repainting make-over on the grounds that “an active artwork that is doing what it is supposed to be doing must always trump a charming ruin”, begs the crucial question – “What is an historic picture supposed to do?” – and he clearly fails to appreciate that it is not Time and Neglect but, rather, restorers who, through their ceaseless Un-doing and Re-doing of pictures, create ruins. Where no auction house or dealer would dream of boasting that a picture on offer has had multiple restorations, museum pictures are treated today like so many bags on an airport carousel waiting to be picked up and done over on the whims and fancies of the next available restorer.

(Incidentally, Jones, Bonsanti, and Lee have by no means exhausted the many due criticisms of the Nativity’s latest restoration makeover. The ruined stone wall behind the repainted Shepherds, for example, has itself been repainted in a manner that robbed it of thickness and perspectival placement and left it running flatly across the picture plane, like so much stone-patterned wallpaper, to serve as a backdrop foil to the hypothetically reconstructed heads, as seen at Fig. 9.)

PROCLAIMED RESTORATION TRANSFORMATIONS – AND THINGS THAT CRITICS OVERLOOK

Where Pope-Hennessy had likened the Sistine Ceiling to Beethoven’s Ninth and noted that “another, more lively, more decorative artist” was emerging, Januszczak whooped at the spectacle of the transformation:

“The thin and neat scaffolding bridge moved elegantly along the ceiling like a very slow windscreen wiper. In front of it lay the old Michelangelo, the great tragedian, all basso profundo and crescendo. Behind it the colourful new one, a lighter touch, a more inventive mind, a higher pitch, alto and diminuendo. It was being able to see both of them at once – Beethoven turning into Mozart before your eyes – that made this restoration such a memorable piece of theatre.”

Unlike Januszczak, Pope-Hennessy had not always welcomed restoration-induced changes. In his 1970 book, Raphael, he observed: “But Raphael restored is Raphael interpreted; it is different from the real thing” – and in 1987 he would likely have known that a recent “Raphael restored” at the Vatican had proved disastrously different from the real thing. In 1982, Mancinelli had said of a bungled, chemically experimental restoration that required extensive repainting by Colalucci in Raphael’s Loggia, “It is the best demonstration that a restoration can also not go along well.” In 2016, Colalucci recalled that the Vatican had faced “a serious problem” when “a new inorganic substance that had not been sufficiently tried and tested” was used.

In 1991, as the Sistine Chapel restorations neared completion, Pope Hennessy reverted to his younger self’s restoration-critical stance and noted:

“In London since 1945 the National Gallery had been the target of ceaseless criticism. There had been intermittent controversies in the press over the cleaning of paintings, but successive directors had enjoyed the support of a passive, compliant board. The policy of Radical Cleaning had been espoused by Philip Hendy (who must have suffered from some retinal defect which made him see pictures as flat areas of colour) and had continued under his successors for so long that proof of the damage done to the collection over thirty years could be seen in almost every room.”

That judgement on National Gallery cleanings was sound and it constituted an international commonplace. Mario Modestini wept for half an hour at the sight the Gallery’s “flayed” restorations; in 1970 Pietro Annigoni painted “MURDERERS” on the National Gallery’s doors in protest; in March 1999 when I visited the Gallery with Professor Anatoly Alyoshin, head of the Repin Institute, St. Petersburg (Russia’s leading institute for the training of picture restorers), he was shocked by the paintings’ uniform brightness and seeming newness. Stopping between galleries, he swept his arm around and said “See! Everything in every school looks as if it was painted in the same studio at the same time.” In a sense, everything had been – after stripping paintings of all they judge extraneous, National Gallery restorers are permitted to this day to paint onto them whatever they take to have been an artist’s original intentions, even with pictures as old and venerated as Holbein’s The Ambassadors and Piero’s Nativity. Old masters are being treated like neglected scores awaiting the life-restoring interpretation of a would-be pictorial Furtwängler, von Karajan or Barenboim – but with the difference that where musical scores outlive their successive interpreters, a painting is its own score.

PURISM AND FAKISM: FALSE AGE CRACKS AND RE-INTERPRETATIONS ON RESTORED PAINTINGS

In the 1990s the National Gallery’s then head of restoration, Martin Wyld, contended: “The ‘Good Restorer’ is the one who ‘does the minimum necessary but not too little… we remove everything not put on by the artist and then use our judgement to get back to the original.” On 8 April 2023, the Financial Times (“Behind the seams at the museum”) reported that the present head of restoration, Larry Keith, said of his restoration of Parmigianino’s Saint Jerome’s vision of John the Baptist revealing the Virgin and Jesus, “We are editing, in a way. The work is informed by science and objective criteria, but there are decisions you take, which on some level are interpretive”. In an Esso-sponsored, BBC-filmed restoration of the Ambassadors (which has ceased to be available), Wyld was seen to have repainted much of the carpet to a new design on the authority of a “carpet expert”, and to have repainted much of Holbein’s famous anamorphic skull to a new and elongated design derived from a computer-distorted photograph of another skull. The Gallery’s defence of Wyld’s first-ever insertion of a Virtual Reality image into an old master painting was its claim that “modern imaging techniques” offered more “scope for exploring possible reconstructions” than the perspectival and optical conventions by which the skull had been produced. The pronounced differences between the Ambassadors’s old original paint and Wyld’s newly redesigned and presumptuously repainted parts of the skull, were concealed by his painting fake lines of cracking onto his own newly painted hypothetical reconstructions to match the real cracks on the real old paint.

PRODUCING “DIFFERENT, MORE POWERFUL” IMAGES

The New York restorer and Kress-appointed Sistine Chapel invigilator, Dianne Dwyer Modestini (formerly Clinical Professor, Kress Program in Paintings Conservation at NYU’s Institute of Fine Arts) – very extensively repainted and artificially distressed the much-damaged Leonardo School Salvator Mundi that fetched a world record $450 million in 2017 at Christie’s, New York – prompting Thomas Campbell, a former director of the Metropolitan Museum of Art, to ask: “450 million dollars?! Hope the buyer understands conservation issues – #readthesmallprint”. Dwyer Modestini had published this small-print report of an early intervention in her decade long undoing and redoing of the picture:

“The initial cleaning was promising especially where the verdigris had preserved the original layers. Unfortunately, in the upper parts of the background, the paint had been scraped down to the ground and in some cases to the wood itself. Whether or not I would have begun had I known, is a moot point. Since the putty and overpaint were quite thick I had no choice but to remove them completely. I repainted the large missing areas in the upper part of the painting with ivory black and a little cadmium red light, followed by a glaze of rich warm brown, then more black and vermilion. Between stages I distressed and then retouched the new paint to make it look antique. The new colour freed the head, which had been trapped in the muddy background, so close in tone to the hair, and made a different, altogether more powerful image. At close range and under a strong light the new background is obvious, but at only a slight remove, it closely mimics the original [paint work] … Most of the retouching was done with dry pigments bound with PVA AYAB. Translucent watercolours, mainly ivory black and raw siena, were used for final glazes and to draw [false age-] cracks…” (Emphasis added.)

That claim was subsequently disproved when the lost Charles I Salvator Mundi emerged in Moscow and was seen to be of an entirely different composition – at which point, the previous resemblance of the painting’s complex shoulder drapery folds to those in the Hollar etching had become more of a disqualification than a potential corroboration.

CHRISTIE’S RESPONSE

In December 2017, Christie’s was presented with photographic evidence (Fig. 11, above, top) assembled by Dr Martin Pracher, a lecturer in technical art history, that showed the changed states of the Salvator Mundi’s (true left) shoulder drapery between 2012, when exhibited at the National Gallery as an autograph Leonardo prototype painting, and 2017, immediately before the $450million October 2017 sale at Christie’s, New York, in which the picture was offered as a then different but supposedly still-autograph Leonardo prototype that enjoyed “an unusually strong consensus” of scholarly support. Under Press questioning (see Dalya Alberge in the Daily Mail) a Christie’s spokeswoman said Modestini had “partially cleaned the passage of paint in the shoulder and the dark streaks disappeared… To imply something incorrect has taken place would itself be incorrect”. Thus, it was insisted that the recently “disappeared” multiple folds, were not folds but mere “dark streaks” that had appeared during Modestini’s 2005-2010 restorations only to disappear under her 2017 ministrations.

INSTITUTIONALLY SEALED LIPS

Of whatever it consisted, Modestini’s last-minute intervention had been made under sworn secrecy at NYU’s Institute of Fine Arts conservation studios, as she disclosed in her 2018 memoir, Masterpieces: Based on a manuscript by Mario Modestini. That is, when the Salvator Mundi returned to New York in July 2017 ahead of Christie’s November sale, Modestini, was instructed “not to inform anyone” when the painting was “delivered to the Conservation Center under guard and in great secrecy”. Modestini further disclosed that a deal brokered by Christie’s ahead of the sale whereby the vendor would receive at least $100million had also been “successfully kept under wraps.”

THE NATIONAL GALLERY’S ABIDING INFLUENCE ON RESTORATION “REVELATIONS”

When Pope-Hennessy deviated in 1987 from his earlier soundness on transformative restorations, he bought into the National Gallery’s longstanding picture cleaning rationale by endorsing two of the 20th century’s most spectacularly controversial restorations:

“In its cleaned form the [Sistine] ceiling has become again what Michelangelo’s contemporaries considered it, one of the supreme achievements of mankind. With Titian, the revelation started in the National Gallery in London, when the Bacchus and Ariadne was freed of centuries of dirt and proved to be painted in an altogether different tonality from any that had previously been supposed.”

That there had been no “centuries of dirt” to remove from the Titian will be shown in Part III. A fuller understanding of Pope-Hennessy’s late-life restorations lapse and an appreciation of the methodological and promotional similarities between the two most controversially transformative restorations in the second half of the twentieth century will be tracked through the records of the two successive National Gallery directors from 1934 to 1967, Sir Kenneth [later Lord] Clark, and Sir Philip Hendy. By the 1980s, that pair’s polished formulations had come to serve as an internationally infectious template for the unbridled techno-experimentalism seen in the Brancacci and Sistine chapels during what, for Colalucci, had constituted the terminus of “the golden age of restoration in Italy, the halcyon era from the late 1940s to the mid-1990s.”

In Part III, we correlate the false scholarship that flowed from the Titian Bacchus and Ariadne and Michelangelo Sistine Chapel restorations, along with the artfully engineered professional endorsements both restorations received from the then highest authorities.

With the Sistine Chapel ceiling we know, but who wrecked Gustav Klimt’s Helene and Sonja portraits?

The restoration injuries on Klimt’s paintings now rival those seen on Michelangelo’s Sistine Chapel ceiling frescoes. Both cases testify to profession-wide failures to read pictures as art and to heed the testimony of photo-records – that is, they testify to the linked failures of restorers who inflict damage and of scholars who accommodate adulterated works within their narrative accounts.

Above, Fig. 1: Top, the after-restoration right foot of Michelangelo’s monumental Erythraean Sibyl on the Sistine Chapel ceiling; below, the after-restoration right hand in Klimt’s 1898 Portrait of Sonja Knips, as seen today (in the Galerie Belvedere, Vienna).

Above, Fig. 3: A detail of Klimt’s portrait of Helene Klimt as seen before restoration, left, in 1956 and after restoration, right, in 2012.

While the injuries to the two artists are comparable in magnitude, the means are quite unalike. With the Sistine Chapel, there is no mystery about the cause. Before the cleaning of the ceiling started (after the cleaning of Michelangelo’s lunettes on the chapel’s upper walls), leading Michelangelo scholars endorsed a Dan Brown-esque claim that self-declared New-Era restorers had uncovered a New Michelangelo whose true traits had gone unnoticed by all those who had, in the artist’s lifetime and for nearly half a millennium afterwards, copied and studied his work. The claim was preposterous, but the fact of the ceiling’s highly controversial and radically transformed appearance was acknowledged by all parties and is now on the historical record. Moreover, twenty-two years after the greatly contested restoration finished, the late chief restorer, Gianluigi Colalucci, admitted that his predecessor at the Vatican, Luigi Brandi, “the old chief restorer”, had warned him that Michelangelo had conducted much if not most of his painting with “pigments perhaps diluted with oil or resin or varnish” on the fresco surface.

What neither Colalucci nor the Vatican ever acknowledged was that in the late 1980s, as we had first reported in 1993, Leonetto Tintori, the restorer of Masaccio’s Trinity in the Santa Maria Novella, Florence, and a member of the international committee that investigated the controversial cleaning in the mid-1980s, had “urged the Sistine team privately to preserve what he termed ‘Michelangelo’s auxiliary techniques’ which in his view included oil painting as well as glue-based secco”.

Cleaning the ceiling had been thought impossible because of the complexity and vulnerability of Michelangelo’s method. To justify the use throughout the ceiling of a ferocious solvent gel that was robotically brushed on and washed off twice in twenty-fours like an oven cleaner in a pre-determined method devised to ensure a homogenous appearance, the restorers and curators claimed – against material and documentary evidence – that Michelangelo had not worked on top of his frescoes when dry. The Vatican never delivered a report on the restoration and now, with the death of Colalucci, never will. The photo-record, thanks to digitalisation and the web will endure.

With Klimt’s oeuvre, the debilitation occurred piecemeal in public and private collections over (roughly) half a century and on no overtly declared programme. Again, thanks to photography, there can be no long-term cover for mis-restorations because we know how Klimt left his works and can calibrate and demonstrate injuries to them, as with the two portraits of Sonja Knips and Helene Klimt.

Klimt’s instruction that those wishing to understand him need only look at his pictures is widely acknowledged but little comprehended. “I am convinced that I am not particularly interesting as a person”, he had written, “if anyone wants to find out about me – as an artist, the only capacity in which I am of any note – they should look carefully at my paintings and try to learn from them what I am and what I have tried to achieve.”

That is no longer possible. It no more occurred to Klimt that his works would cease to bear true witness than it had to Michelangelo that he would one day be hailed as the Matisse of the Renaissance by a restorer (see our “Maestro Colalucci: His Method and its Madness”, Jackdaw, May/June 2021, and “A crime against the artist”, The Independent, 22 November 1991, at Fig. 34 below.) Now, a century on from Klimt’s death and with scarcely a single picture true to its original self, the most charitable view of scholarly silences on injuries might be to assume that those who depend on access to Klimt’s works and records either know or fear they cannot afford professionally to embarrass private or institutional owners by citing past or recent injuries. However, Klimt scholarship and publications have exploded in recent years and it is now possible (through photo-illustrations) to make fair appraisals of the various changes his works have undergone at the hands of restorers – even though their actions remain almost nowhere acknowledged.

HELENE KLIMT: ASKING THE RIGHT QUESTIONS

Fig. 4, above: Top, Klimt’s portraits of Helene Klimt and Sonja Knips, as bracketed in the precious and giant – it weighs 16 lbs – 2012 Taschen Gustav Klimt The Complete Paintings, Ed. Tobias G. Natter; above, the Klimt and Knips portraits as published with Klimt’s approval between 1908-14.

As Dr Natter hoped, the Taschen book is now a standard work of reference. His ambition to supplement updated “details about each work, its provenance, exhibition history and selected bibliographic references” with a picture of “how it was received in its day” proves richly informative. Notwithstanding such art historical diligence, no account is given of what restorers euphemise as pictures’ “conservation histories” and therefore this book, like all others in the field, fails to address how each work looked in its day and to estimate how much or how little it does so today. Seemingly failing to recognise that every work of visual art starts life as its own primary document, this ambitious book takes what restorers have left in their wake as synonymous with the art Klimt produced. As is customary in the field, Natter expresses deep and sincere gratitude to all owners and “in particular, the private owners” for their trust, helpfulness, and inspiring conversations.

ART HISTORICAL NARRATIVES

One of the book’s contributors, Susanna Partsch, (“Paintings of women”), sets the above two portraits as staging posts in a now prevalent art historical schema:

“The earliest portraits on display at that occasion [a 1903 Klimt exhibition] were the private ones of his young niece Helene Klimt and the Portrait of Sonja Knips both of which were completed in 1898. The some twenty portraits that Klimt produced between 1891 and 1898, most of them showing anonymous models, seem to have been finger exercises on the way to a new style.”

With the Portrait of Helene Klimt, the artist’s then six years old niece who became his ward on the death of his brother (Fig. 4, above left), Natter jumps straight into formalist art criticism:

“If Klimt’s portraits of the early 1890s had shown him dissolving line and blurring colour in a painterly manner, the artist here explores the harmony of the strict profile view. This is reinforced by the precision of the page-boy haircut, the neutral background and the high-necked blouse, its fabric interpreted and ennobled by the generosity of the execution. The dualism of mimesis and dissolution, of faithful reproduction and painterly openness, is already in evidence here as a stylistic means.” (Emphases added.)

Thus, the head is said to be painted in one manner and the blouse in a radically contrary one, but this supposed pictorial dichotomy rests on an assumption that the picture’s present traits are as when originally executed when the photo-record (at Fig. 3 and below) testifies that they are not. Natter cites but does not reproduce an early record of the Portrait of Helene Klimt: “A previously unheeded photograph published in the magazine Das Interieur in 1911 [that] shows the child’s portrait hanging in a bedroom in the Flöge sisters’ home in Ungargasse, Vienna (N.N. 1911).” Having brought photography to the table, Natter neglects to consider the testimony of the earliest published photographs of this painting including one above at Fig. 4 of 1908-14 which Klimt himself had carefully vetted and endorsed.

This profession-wide neglect of historical photo-records persists even as Klimt’s own use of photography attracts attention. In 2012 Prestel published Gustav Klimt & Emilie Flöge Photographs, edited by Agnes Husslein-Arco and Alfred Weidinger, the scientific director of the Linz Upper Austrian State Museum; former vice-president of the Belvedere in Vienna; and a digital and film photography specialist with a preference for black and white images. Agnes Husslein-Arco, a former figure skater and Sotheby’s Austrian director, was director of the Belvedere museum between 2007 and 2016 and is credited with transforming it into a major tourist attraction in Vienna. In the book’s preface, the then director said: “The product, a chronological presentation of photographs and snapshots, illustrates a biographical panoptic of these two personalities who were so influential in the fin-de-siècle art world…The following contribution by Alfred Weidinger provides information about Klimt’s relationship to photography and the use of the same in his artistic creations.” Weidinger wrote: “The reference to Klimt’s involvement with photography, only briefly sketched out here, is meant to offer a first look at a hitherto neglected area of Klimt research, and, at the same time, make evident the importance of this medium to the artist.”

Above, Fig. 5: Left, one of a group of Moriz Nähr photographs acquired by the Austrian National Library in 1943 that recorded both Klimt himself and “revealing reproductions” of his paintings, as here above left with his 1900 The Large Poplar I. Above right, The Large Poplar I, as reproduced (with slightly trimmed edges) in Alfred Weidinger’s 2007 Prestel Gustav Klimt – an earlier massive and compendious complete catalogue with specialist essays which had weighed in at a respectable 10 lbs. Weidinger expressed the hope that the book, which offered a fundamentally new basis for research, “holds out an invitation to discover many new aspects of the life and work of the great painter whose artistic home is the Vienna Belvedere.” (We welcome and accept that invitation.)

A SECOND OPINION

Above, Fig. 6: Left, Klimt’s 1898 portrait of his niece (and later ward), Helene Klimt, as published in Emil Pirchan’s pioneering 1942 and 1956 book Gustav Klimt and, centre and right, Helene, as paired with a Fernand Knopff profile portrait by Alfred Weidinger in his 2007 Gustav Klimt.

As with Dr Natter, Dr Weidinger’s catalogue entry on the Helene Klimt portrait made no reference to the Pirchan book’s photographic testimony. Instead, he drew attention to Klimt’s apparent indebtedness to an 1890 Fernand Knopff portrait in which “a severely profiled half-length portrait faces to the left, with an almost monochrome background which is divided into two areas by a thick brown vertical line.” Weidinger further notes that while Klimt “reduces his composition to the girl and the pale background we may detect a reminder of Knopff’s composition in the group of vertical lines in the front of Helene’s face, which in the Jeanne de Bauer portrait, functions as a special accent”. The stylistic comparison with Knopff is apt and fair but no mention is made of the photographically recorded fact that the lines to which Weidinger refers had not been visible in the picture in its 1908-14 and 1942-1956 photographs.

Weidinger takes pride that it had been “a major concern of ours to see, as far as possible, all Klimt’s pictures in the original and to take new photographs of them” and that their wishes had been met in the great majority of cases. That the lines in the portrait’s background had not previously been present must mean that they had emerged in a post-1956 restoration, which in turn suggests that a restorer had uncovered and left exposed a feature previously begun and then painted out by Klimt, perhaps because of second thoughts about introducing a parallel secondary motif that would have stood distractingly in competition with the picture’s subject.

Above, Fig. 7: Left, Klimt’s portrait of Helene Klimt as recorded before 1956 in Pirchan; right, the portrait as reproduced by Weidinger in 2007.

Had Weidinger compared the above pair of images he would surely have noted not only the late emergence of the lines but also the many changes to the blouse – and perhaps have offered some account for them. Instead, and seemingly accepting the 2007 state as if Klimt’s own, he drew a stylistic distinction between the treatment of the undamaged head – “the fine brushstrokes with which Klimt renders her hairstyle and profile give a draughtsman-like character to the girl’s head” – and the body, where: “the treatment of the high necked, puff-sleeved blouse, which Klimt paints in cream and light blue tones, is sketchy.” In 2012, Natter saw more in the blouse than sketchiness – viz: “fabric interpreted and ennobled by the generosity of the execution”; and, in the now disrupted head/blouse relationship, “a dualism of mimesis and dissolution, of faithful reproduction and painterly openness”. The photo record shows that both scholars missed countless injuries and adulterations to the blouse – including superimpositions that crudely redrew the collar and the arm’s contours – all of which they took to comprise evidence of a significant step in the march of Klimt’s stylistic development of which Partsch spoke in 2012.

Had Weidinger addressed such a comparison as that above, he would likely have seen that the draughtsman-like character of the head had been no less evident in the economical but precise elegant treatment of blouse, too, and that viewed as a whole, the work had originally shown no great dichotomy of pictorial means and, rather, comprised a beautifully measured record of a young girl’s dutifully patient self-conscious expression and resolute little soldier-like stance.

Above, Fig. 8: Left, Klimt’s portrait of Helene Klimt as in Weidinger, 2007 and, right, as reproduced by Natter in 2012.

The above, same-size, greyscale, direct photo-comparison shows that the painting underwent further changes between 2007 and 2012: the long-invisible vertical lines that emerged in 2007 had by 2012 turned more clearly towards the child suggesting a framed picture on a parallel background wall; an area of damage in the centre of the picture’s left edge that was visible in 2007 has been touched out, as were several scratches of long-standing.

Above, Fig. 9: Klimt’s portrait of Helene Klimt as recorded, left, between 1908-14; as before 1956, second left; as by Weidinger in 2007, second right; right, as by Natter in 2012.

Comparing four same-size successive photographs above shows the first two records of the blouse (1908-14 and 1942-56) to be identical and radically different from the two in 2007 and 2012. The post-2007 traits that are now enshrined in the literature as “sketchy”, or an “ennoblement by generosity of execution” can be seen on a simple photo-comparison to be products of hands other than Klimt’s. The photographic record incontrovertibly shows that in this portrait, autograph features that survived until at least 1956 were subsequently weakened or erased, and that new and stylistically alien contours had been added in an evident attempt to simulate something of the then-botched blouse’s original coherence and richness of design. Thus, field-leading contemporary scholarship had failed to notice, acknowledge, or condemn a vandalising act of bowdlerisation. Instead, it has incorporated a restorer’s deformations into a celebratory narrative of a privately owned work that is on loan to a public museum (Berne, Kunstmuseum).

Above, Fig. 10: Top, left, Klimt’s Portrait of Helene Klimt in Pirchan, 1956; and, top right, in Weidinger’s 2007 Gustav Klimt. Above, left, Klimt’s 1894 Seated Young Girl; above, centre and right, a diagram showing first the 1956 Pirchan illustration with the then folds of the blouse outlined in black, and right, with what we take to be a post-1956 restorer’s superimpositions also identified in black.

Weidinger’s comments on Klimt’s indebtedness to Knopff (and to Whistler) are constructive and, in Klimt’s early Seated Young Girl, above left, he sees indebtedness to both Klimt’s brother, Ernst, and their joint master, the painter Hans Makart. Despite such fine-tuned stylistic discrimination, Weidinger seems to see no relation in the Seated Young Girl to Helene’s blouse. Had Natter addressed the losses and additions in the post-1956 blouse, would he have spoken of a “dualism of mimesis and dissolution, of faithful reproduction and painterly openness, [that] is already in evidence here as a stylistic means” in Klimt’s supposedly contrasting handling of the head and blouse? The blunt tuth is that, with Helene’s blouse, the dissolution was chemically and physically induced decades after Klimt’s death by an unidentified restorer on an unrecorded/undisclosed occasion.

SONJA KNIPS

Above, Fig. 11: A 1915 photograph of the Sonja Knips portrait in the dining room of the Villa Knips, as in the giant 2012 Taschen book, left; as in the Neue Galerie’s, 2008 Gustav Klimt: The Ronald S. Lauder and Serge Sabasky Collections, Ed. Renée Price, where a modern colour photograph of the painting has been superimposed, centre; and right, top and centre, as in Christian M. Nebehay’s, 1976 Gustav Klimt; bottom right, Sonja Knips as published respectively in Weidinger, 2007, and Natter 2012.

Natter and Weidinger both carry historic photographs showing Klimt paintings in the background but without comment on their then appearances. The Nebehay image above, right and centre, is small and printed on poor paper but even at this level of reproduction, it gives indication of the picture’s tonal hierarchies and dispositions – the subject is brilliantly lit on the left and moves into shadow on the right of the picture.

Klimt’s paintings were much photographed in his lifetime (that is, before his death in 1918), many were seen in their exhibited environments, some were photographed before being first exhibited and then again after subsequent reworking. For all this, and even though both 1898 portraits at Fig. 4, top, have exceptionally long and secure photo-histories, their narratives have been written without regard to such evidence and in terms of constituting steps towards subsequent pictorial developments – which progressivist schema happens to provide perfect art historical cover for dramatically altered pictures.

Of the Portrait of Sonja Knips, Dr Natter summarises: “This graceful female portrait marks a turning point in Klimt’s portraiture and is rightly considered a prelude to his Secessionist works. The sitter is portrayed in life size, seated in an outdoor setting. The square format is new and represents a fundamental choice whose possibilities Klimt would explore over the next few years. New, too, is the corresponding juxtaposition of light and dark, foreground and background, fullness and void.” That account was more consistent with the picture’s 2012 published appearance, Fig. 4, top right, than when first recorded as at, Fig, 4, bottom right, where today’s “void” comprised distinctly articulated spaces, forms and, even, mini-figures.

Of the painterly means, Natter adds: “Klimt employs a differentiated manner of painting, executing some areas of the portrait in a cursory fashion while focussing with great precision upon others. He thereby creates a fascinating contrast between the naturalistically modelled head of the sitter and the gauzy shimmer of her dress. This latter conceals a wealth of painterly effects and is infused with a rustling tension by a cascade of multiple parallel brushstrokes. Klimt at the same time camouflages the highly artificial nature of the arrangement as a snapshot.” In terms of a perceived stylistic dichotomy no mention is made of the picture’s former second carefully composed and precisely, naturalistically realised component – the now transformed and deranged small red sketchbook, as seen at Figs. 1 and 2.

AN AFFAIR – OR NOT?

With Klimt and his female subjects there is always a relationship issue and with this picture scholarly differences have arisen. Natter is agnostic: “Whether – as some suspect – Klimt and Sonja Knips enjoyed an intimate relationship, cannot be verified. But it is certainly the case that the painter presented her with one of his sketchbooks as a token of his particular affection.” He first speculates: “Whether he indeed pressed one such red leather-bound book into her hand during a sitting, because he felt the painting needed an accent of colour at that point remains conjecture”. (The reported source for this formalist reading had been the subject herself, as discussed below.) Natter takes the fact that such a scenario is conceivable to be “a clear reminder that Klimt, unlike the expressionists, continued to legitimize internal compositional requirements by cloaking them in external motifs.” Thus, a key question is begged: Whatever the relationship between the artist and the sitter, the book served an essentially formal pictorial purpose – the pink dress had “needed” on chromatic/pictorial grounds to be offset by a small red parallelogram of which just such an instance was conveniently to hand in a book of sketches Klimt had gifted to the picture’s beautiful subject whom he had known since her teenage years.

Thus was a formalist painterly purpose attributed to an immensely charged and fastidiously depicted small book, even after its – undiscussed – visually deranging transformation into the quasi-Cubist construct at Figs. 1 and 2.

TWO SCHOLARLY TAKES ON THE TWO PORTRAITS

Above, Fig. 12: Top left, the infra-red image of the Sonja Knips portrait published by Weidinger in 2007; top right, the second oldest (1908-1914) photo-record of the painting; below, Klimt’s 1896 Girl in the Foliage as published, left, in Emil Pirchan’s 1942 Gustav Klimt, centre, in Johannes Dobai’s 1978 Klimt, and, right, by Weidinger in 2007.

Weidinger situates the Sonja Knips portrait in the same part of the oeuvre’s developmental arc but also within social artistic and fashion contexts:

“This portrait is considered a turning point in Klimt’s portrait painting…the beginning of a series of large format portraits of ladies, predominantly of the prosperous, Viennese upper-middle class…and their wish for prestigious portrayal…[Knips] was one of his few models from the circles of – albeit minor – nobility…Klimt portrayed Sonja Knips sitting in a chair. A portrait formula he had already tried out in small-format portraits of ladies of 1896-98. The diagonal division of the painting into two zones places the subject opposite an empty space in tones of dark brown – a motif also used in Whistler’s Arrangement of Grey and Black No 1: Portrait of the artist’s mother (1867-71) and already taken up by Klimt in his Lady in an Armchair (cat. 106) and Lady by the Fireplace (cat. 106)…”

While the social/professional account of Klimt’s developing career is of interest, the perceived dichotomy of subject and void better accords with the picture’s present appearance than that seen in the special reproduction of 1908-14 (Fig. 4, right). Weidinger’s “empty space” had been closer than Natter’s “void” to the picture’s original and distinctly articulated spaces and forms but, then, he brushed away all claims that Klimt had originally “painted figures, a pool, or even a horse in the background which he then overpainted” on the grounds that no figural elements can be identified in the infra-red image. Thus, the testimony of a single undated technically penetrating image trumps all the compendious photo-records that testify to the contrary.

Above Fig. 13: Left, Dante Gabriel Rossetti’s 1868 Lady Lilith; right, the undated infra-red image of the Sonja Knips portrait made – presumably – at the Belvedere, Vienna.

In lieu of an evaluation of the infra-red image in the context of the picture’s full photo-history, Weidinger pursues stylistic antecedents and influences: “The all-over brushstrokes suggest a landscape of bushes and trees such as Klimt had already once depicted in his Girl in the Foliage”, as above Fig. 12. Further, “In the upper left-hand corner of the picture there is a recognisable view, accentuated by a flower. Since Sonja is presumably in a garden, as suggested by the lilies above her head, this may be a view of the landscape, similar to Rossetti”. (In the Rossetti above, the landscape view is a reflection in a framed mirror.)

Above, Fig. 14: Above, Rossetti and Klimt details; centre, details, of Klimt’s Sonja Knips and Emilie Flöge portraits before restorations; below, Klimt’s Two Girls with Oleander.

Notwithstanding his reading of the infra-red testimony on foliage, Weidinger adds: “Admittedly, it is also possible that the setting is an interior room.” The picture’s present void may thus be read either as an ex-interior or an ex-garden or even a landscape – but which and how to decide? While the lilies above Sonja’s head might have been made in homage to Rossetti’s roses, in terms of Klimt’s stylistic development, they might also be considered to have anticipated his first placement of a decorative foil behind a portrait, which scholars have located in Klimt’s slightly later and more abstracted 1902 portrait of Emilie Flöge, as above, centre right. At the same time, Klimt might have been nodding back to his recent self’s 1890-92 counterpointing of closely adjacent flowers and young female subjects in the Wadsworth, Connecticut Two Girls with Oleander (as above, bottom) – which picture Weidinger nicely pairs with Alma Tadema’s deep-spaced 1893 Unconscious Rivals, at Bristol City Museum.

KLIMT’S CROPPING DEVICE

Above, Fig. 15: Top, left, J. C. Leyendeker, Couple Descending a Staircase, c. 1925; right a detail of Klimt’s Sonja Knips portrait; above, left, John Singer Sargent’s 1884 sensation-generating “Madame X”; centre, Klimt’s c.1894 Portrait of a Lady in Black as seen today; right, Klimt’s Lady in Black as shown in 1978.

Sonja Knips is shown wearing an elaborate evening dress and seated in a softly upholstered armchair. Her and the chair’s images are cropped by the bottom and right-hand edges of the picture and therefore are brought closer to the viewer while left without a clear relationship to a ground plane. Such cropping facilitates key modernist picture plane-asserting strategies – as evident in the above Sargent and Klimt portraits of a standing lady in a black costume. Sargent sets the whole figure in a dark enveloping but bounded space. The fused figure and (vertically, not horizontally, cropped) table are as securely placed on the floor as a linked piece of sculpture on a plinth. Adding to that palpable sense of the body, Sargent’s light picks up form-disclosing drapery configurations within the dress’s overall blackness. That mix of a theatrically lit figure and minimal but precisely realised furniture may have found echo in the American illustrator J. C. Leyendecker’s brilliant advertisement for Arrow Shirts (above, top left).

With the cropped chair and figure in Klimt’s lady-in-black, above centre, we are given fewer such lights and altogether less spatial orientation – except in narrow overlapping recessional relief: the chair overlaps the lady, who overlaps the hanging carpet and the wall, which overlaps a second parallel wall. While such treatment can be read as a staging post in a long march towards modernism, Klimt had shown fondness for precisely such compositional parallelisms and eschewing of deep spaces at the height of his neo-classical “historicist” period, as recapitulated in his Young Girls with Oleander at Fig. 14 above.

In any event, whether a recapitulation or an anticipation, in his lady-in-black, the emphatically extravagant shapes of the black dress pin the subject to the picture plane like a butterfly to a board. Or, rather, they do so in the picture’s present restored and buffed state. Originally, and as late as in its 1978 appearance as above right (in Johannes Dobai’s Klimt) when much of Klimt’s complex and nuanced hierarchy of values survived, the lighting was not uniformly bright but softer and more focussed, in a more Sargent-like theatrically light-animated space. Then, the décolleté was rendered both more brilliant and more plastic by adjacent as well as internal tonal values. A darker tone at the back of the neck/shoulder in combination with the more shadowed profile face and shoulder (offset by a spotlighted halo) bestowed a more columnar, sculptural neck.

Klimt was then disposing lights and shades imbibed from his classical training like a masterly cinematographer with his lamps. The great British cinematographer, Jack Cardiff, learnt his lighting in childhood from studying old masters in museums and his lighting was so skilful and flattering that great actresses of a certain age would only appear in films employing him. (One of Klimt’s sons, Gustav Ucicky, began a distinguished filmmaking career as a camera man in 1916, as Nebehay discussed in his 1992 Gustav Klimt: From Drawing to Painting.)

THE FULL PHOTO-RECORD

Weidinger’s inclusion of the Belvedere infra-red image raised awkward methodological questions. With a century old painting, can a “below-the-surface” view reliably locate a work’s original appearance? If infra-reds are admissible evidence, what grounds exist for excluding the testimony of all other photographic records?

Above, Fig. 16: Top, Klimt’s Helene and Sonja portraits, as published between 1908-14 through the H. O. Miethke gallery in Vienna; and (above), the portraits as published in 1942 and 1956 in Emil Pirchan’s Gustav Klimt.

In Klimt’s portrait of Sonja Knips, the group of lilies shown above and close behind her head must be presumed to be either cut flowers in a hidden vase or some free-floating artistic/symbolic device. Presently (as at Fig. 11, bottom right), the subject herself aside, all is indeed darkly mysterious and serves effectively as a backdrop/foil to the brightly lit head and spectacular dress – almost as in Leyendecker (Fig. 15, top left) when the early photo-record shows Sonja set in an articulated and bounded space.

In 1908, Klimt and Galerie Miethke had collaborated on the publication of a group of collotypes marketed under the name Das Werk Gustav Klimts, a project aimed to distribute his work to a new type of collector. From 1908 to 1914, Klimt personally supervised the 50-print enterprise, which faithfully reproduced what he thought to be his most important paintings from 1898 to 1913 and he designed a unique signet for each print, which was placed beneath the image and impressed in gold ink. Emperor Franz Joseph I of Austria was the first to own the initial instalment.

Where some might sniff at the enterprise’s commercialism, Weidinger reminded us (2008, the Tate, “The master of erotic theatre” ) that: “Contrary to what people think and what has been written about the Secession, it was not a museum, but a gallery operation that generated cash. The artists had families and needed the money.” In the event, those limited edition ultra-high quality photographic reproductions generated a niche market as quasi-artworks. (See, for example, 1stDibs; Acquisitions of Fine Art and the Jason Jacques Gallery.)

If the art historical testimony of these images remains neglected, their role in the withdrawal of the Klimt group of artists from the Secession was reported in Nebehay, 1992:

“In the spring of 1905, after a difference of opinion regarding Carl Moll’s activities in the then leading gallery H. O. Miethke, the ‘Klimt group’ had left the Secession. This group, which comprised apart from Klimt, architects such as Josef Hoffmann and Otto Wagner and artisans such as Kolo Moser, was opposed by the so-called painter group, led by Jose Engelhart, who protested against Moll’s exhibition activities at Miethke’s which, they said (not without reason) were damaging to the Secession. When it came to a ballot, the opponents – having roped in one of their members then staying in Berlin – won by only one vote. Again, the real talents gathered around Klimt: the rest were mediocre. The eight wonderful years of the Vienna Art Spring were over: after the ‘Ver Sacrum’ came no mild summer, no fruitful autumn, no contemplative winter.”

A MOST ADVANCED METHOD OF PHOTOGRAPHIC REPRODUCTION

The following technically informative account of the role of the originally created portfolio of ten Klimt works is given by 1stDibs:

“…the folios of collotype prints published by H.O. Miethke in Vienna between 1908-1914 known as Das Werk Gustav Klimts, are important art documents worthy of as much consideration for the bold stand they take on established ways of thinking about artistic collaboration as they are for their breathtakingly striking images…Miethke’s pioneering art house had become Klimt’s exclusive art dealer and main promoter of his modernist vision. Paul Bacher and Carl Moll, a founding member with Klimt of the Vienna Secession, who all broke away during the rift in 1905, took stewardship of the gallery following the fallout with the Secession. Das Werk Gustav Klimts is a prime example of Miethke’s masterful and revolutionary approach to marketing art. Miethke’s innovative marketing strategy played to a penchant for exclusivity. The art gallery and publishing house utilized the press and art critics – such as Austria’s preeminent Art Historian, Hugo Haberfield, who became Director of the gallery in 1912 – as a means of gaining publicity as well as maintaining effective public relations. Miethke used the grand exposition format to extend the art gallery’s market reach, cultivating their product’s prestige by stroking the egos of current art patrons while simultaneously creating accessibility for newcomers and other avid collectors to share a relative proximity to other wealthy and respected members of the art collecting community… Between 1908 and 1914, H.O. Miethke published a total of 5 instalments of print folios of Klimt’s painted work, each comprising 10 prints. The series was limited in availability to 300 and purchase was arranged through subscription. Each issue was presented unbound in a gold embossed black paper folder…These folios were not comprehensive of Klimt’s work; but rather, they feature what he believed were his most important paintings from 1898-1913. Only 2 collotypes in each folio were multicolored…Alice Strobl’s scholarship on this subject confirms Klimt’s involvement throughout the 7-year production process. The Virgin, for example, which dates from c. 1912-1913, was created well after the portfolio was first conceived c. 1908. Its corresponding signet, therefore, could not have been created a priori [see Fig. 17 below] … Understanding the fragile nature of the collotype printing process also reinforces this project’s distinctive and ground-breaking characteristics. The fragile collotype plates could not be reused. As such, this necessitated the completion of a run on the first go and also dictated the limited production numbers such as the 300 pulled for Klimt’s Das Werk. Printed by hand, the collotypes required deft handling by the printer, k.k..Hof-und Staatsdruckerei. A complicated and lengthy process involving gelatin colloids mixed with dichromates, the creation of 16 color separation thin glass filters to achieve the light-sensitive internegative images which could faithfully capture all of the painting’s tonal gradations and colors, exposure to actinic light, and delicate chine collie papers which allowed for greater color saturation, the printer’s collaborative role in capturing and transmitting Klimt’s nuanced paint strokes is nothing short of remarkable. Ernst Ganglbauer, Director of kaiserlich-konigliche Hof-und Staatsdruckerei (1901-1917) was eager to promote art prints. An innovator, he elevated the Kaiser’s press to international renown by assembling the best of the best in technical and aesthetic advisors. This dream team of free-lance artists developed adaptive uses for the Staatsdruckerei’s existing equipment and, together with the printers there, perfected the multicolor print process for Miethke and Klimt’s Das Werk.
(Emphases added.)

Clearly, these early Klimt-approved images were as good as could be made at the time and might properly form the starting point for any comparative study of the two pictures’ photo-records. Their then technological sophistication was truly remarkable: in key respects, the multiple colour separations made to capture the exact tones and hues anticipated by a century the ground-breaking multi-spectral high-definition digital camera invented by the engineer/optician Pascal Cotte of Lumiere Technology.)

Other collotypes made and produced in limited-edition books today sell at eye-watering prices. In 1942 and again in 1956 the two portraits (along with many others) were published in Emil Pirchan’s book Gustav Klimt, as above at Fig. 16.

PHOTOGRAPHIC DEMONSTRATIONS OF RESTORATION INJURIES

Above, Fig. 17: Left, a collotype print of Klimt’s The Virgin published between 1908-14 through the H. O. Miethke gallery in Vienna, here overlapped by its Wiki image. The chromatic and tonal differences between the two records speak for themselves.

Above, Fig. 18: Top left, Klimt’s Sonja Knips portrait (a Miethke 1908-14 collotype); right, the left section of the Belvedere infra-red image published by Weidinger in 2007. Above left, the portrait as in 2007 and, above right, in 2012.

The above comparison of the testimony of the 1908-14 photo-record and the pre-2007 infra-red image, suggests that formalist accounts of a light v. dark triangular pictorial dualism are over-stated, space-denying simplifications. Note that almost half-way up the photo-record’s left-hand edge, the picture is bisected by a short horizontal tonal division between a darker upper area and a less dark, seemingly shadowed area of ground. That crisp horizontal division speaks not of a void but of a distinction between a wall and a ground plane. Such an architectural reading is further indicated in the top left-hand corner of the infra-red image by a seeming bottom corner of a window or aperture. On the combined evidence of the Klimt-approved Miethke collotype and the Weidinger infra-red image we can conclude – much as with the Helene portrait – that Klimt had toyed with the idea of inserting an implicit rectangular feature (a fragment of a window, or aperture) in the picture’s top left-hand corner which would have echoed the picture plane but that he had decided against it and painted it out. Having painted out the feature, Klimt then pulled that corner of the picture back towards the picture plane with the “echoing” parallelism of the flowers’ motif. (Had the superimposed fragmentary flowers not been in place, the restorers might well have semi-excavated the window aperture as with the frame behind Helene.)

With further regard to the Klimt-approved Miethke-recorded spaces and structures, if we read leftwards from the centre of Klimt’s strategically placed little red book, another tonal division runs horizontally before turning upwards diagonally to meet (almost) that of the wall/floor junction running in from the left edge. Above this lower division there are leaf-like formations that suggest a shrub or topiary that runs upwards and behind the lilies. However, on the infra-red image detail, above right, the leaf-like formations also run below the book and into the area that had read in 1908-14 as the shadowed section of the floor. That would indicate that Klimt had painted out the lower leaf-like forms to produce the ground plane as recorded in the Miethke gallery collotype. Today, as seen above in 2007 and 2012 (Fig. 18), the originally distinct tonal zones have been subsumed in the larger, undifferentiated dark zone that is now taken as a Klimt-intended emptiness or void. However, even today, within this supposed void, a seeming tableau of small figures and statuary can still be glimpsed despite having been ruled out on the supposed evidence of the sole infra-red image.

FIGURES IN THE BUSHES OF A TRULY EXCEPTIONAL PICTURE

In her 1989 Klimt, Life and Work, Susanna Partsch wrote of the Knips portrait:

“Sonja Knips is sitting in a park or garden, on the edge of a light-coloured chair…The light earth contrasts with the dark background, which has some red in it on the left. There is something mysterious about the dark, irregularly applied colour, which casts shadows on the light earth. There is the merest suggestion of a pond in the background. Against this background Sonja Knips sits in a sumptuous pink dress with high neck and ruffles, narrow waist and full skirt. The lower edge of the picture cuts off the bottom of the skirt, which is therefore not visible, any more than are the feet. With her left hand, Sonja Knips grips the armrest, as if she were just about to get up, and this impression is strengthened by the way she sits on the edge of the chair but is contradicted by her right hand, which rests quietly on her leg clasping a red booklet. Nor does the expression on her face suggest that she is about to move, she gazes straight ahead out of the picture, disquieting in her immobility. This portrait is the only one with a hint of landscape in the background. Klimt painted many landscapes and many people but kept the two distinct, which makes this portrait truly exceptional. It was painted at a time of upheaval, when Klimt had abandoned historicism but not yet found his own style. In the same year he painted his first landscape pictures. The orchids and the pond in the portrait represent a subdued symbolism, hinting at sumptuousness and mystery.”

That nicely observed account presumably preceded the picture’s restoration. Twenty-three years later in her 2012 Taschen essay “Paintings of women” Dr Partsch writes of the same picture:

“…She is sitting at the very front of the seat of a generously sized armchair and is leaning on the upholstered arm as if she were about to stand up. In her right hand she holds a small red book. With her body angled to the left, she has turned her head so that she is looking straight out the picture and fixes the viewer with her gaze. The curls of her hair are taken up in the ruffles of her dress, while her head is framed as a whole by a backdrop of flowers – lilies or orchids that are either growing in a garden or standing in a large vase on the floor. Beyond the top of the canvas, blooms and branches form an invisible arch that descends into the picture in the top left-hand corner in the shape of another flower. This left half of the picture consists of two planes clearly divided by their colour. The [lower] area of pale brown, in some places shot with green, in the lower left-hand corner barely distinguishes itself from the tender pink dress and forms a floor of some kind. The dominant field of blackish brown, which provides a foil to the flowers and the female sitter, contains several lighter patches. These have inspired numerous interpretations, with some authors suggesting that Klimt had painted over what was originally a garden setting. Infra-red photography has failed to confirm this theory and it thus remains unclear whether Sonja Knips is situated in a room or outdoors in a garden…”

The two accounts of the same picture by the same author differ – but what has changed if not the picture itself? A certain hardening of a feminist stance emerges. Sonja is now more assertively “looking straight out the picture” and “fixes the viewer with her gaze”. Partsch now complains generally that Klimt’s portraits of women “seldom reveal the individuality, character or abilities of the women they depict” and raps him over the knuckles for having reduced one female subject, his Rose von Rosthorn-Friedmann of 1901, “to a figure of elegance and sensualism” while neglecting to indicate that “she was a pioneering female alpinist who became the first woman to climb the East Face of Watzmann and Thurwieserspitze in the Ortler Alps”. The complaint seems something of an ideology-signalling contrivance: short of tying some rope, climbing boots and crampons around his subject’s neck, it is hard to see how Klimt might better have done justice to her than as below at Figs. 19 to 21.

A digression is merited on this female portrait: the charge of “reducing” his subject to elegance and sensualism – as if those two traits preclude all others – is unfounded. Klimt, who said of Alma Schindler “She is beautiful, she is clever and witty, she has everything that a fastidious man can expect from a woman”, did not rob the subjects of his commissioned female portraits of dignity, gravity or intelligence, any eroticising tendencies notwithstanding – and nor was he formulaic in his portrayals: every subject prompted a re-invention, and a re-invention that was preceded by multiple exploratory studies. Natter’s close attention to the receptions initially given to Klimt’s paintings is pertinent on Rosthorn-Friedmann: “her death, still relatively young, on 19 January 1919, prompted Hugo von Hoffmannsthal to write a letter to her widowed husband, in which he emphasized the striking beauty, intelligence and warmth of this exceptional woman.”

Above, Fig. 19: Left, Sargent’s “Madame X”; right, Klimt’s portrait of Rose von Rosthorn-Friedmann, as in Natter, et al, 2012.

In Rosthorn-Friedmann Klimt fused glamour athleticism and grit, if not steel (note the eyes; the pinched nostrils; the mouth and its bared teeth); not to mention the sinuous lightness of a delicately perched and coiled figure whose torsion more than vies with that of Sargent’s “Madame X”. With what is known of his subject, all would seem to be in order in Klimt’s painted account. Partsch casts doubt on Alma Schindler’s claim that Klimt had just begun an affair with his model, but Natter spells it out: “In her diary entry of 19 January 1900, Alma mentioned Klimt’s latest liaison: ‘What’s more, he’s just started an affair with Rose Friedmann, that old hag! He takes where he finds.”

Above, Fig. 20: Klimt’s 1901 portrait of Rose von Rosthorn-Friedmann as seen in the two deluxe Klimt catalogues: that is, as in Weidinger, 2007 left; and as in Natter, 2012, right.

We cannot vouch for the veracity of the two books’ reproductions of the painting and both publishers take fair pride in their productions. Yet, as seen above, there are numerous chromatic and tonal differences in the respective photo-illustrations which, given the chronology, suggest a post-2007 restoration. Because Weidinger attempted to have every Klimt work re-photographed for the 2007 Prestel book’s catalogue we can, perhaps, safely take the images above left to be a fair record of the then state of the picture. So what might account for the general losses of tonal and chromatic vivacity as seen on the right in 2012? For example, Partsch notes (Taschen, 2012) that “her dark, coiffured hair is barely distinguishable from the blue of the background”. That indeed was the case, but it had not been so in the 2007 Weidinger reproduction as above left, centre, when the blues, blacks and whites were warmed and enriched by red. The evident weakening of the strong form and shape of the greatly more lustrous hair in 2007 is not an isolated incident within the picture. It had been accompanied in 2007 by a markedly sharper, darkly unified near-diamond shape of background enclosed by the arm and body.

WHICH IS THE REAL KLIMT?

Above, Fig. 21: Left, Klimt’s working drawing for the Rose von Rosthorn-Friedmann portrait (which picture is held in a private collection in Switzerland); right, a detail of the painting, as reproduced respectively in: 1988, Gabriella Belli, Gustav Klimt Masterpieces; 2007, Weidinger, et al; and in 2012, Natter, et al.

The picture had long been thought lost and was known only by a single photograph. Unfortunately, no one seems to have reproduced that early record. What is to be made of the above trio of details recorded consecutively in just twenty-four years? With the above detail, we see three successive states: 1988; 2007; 2012. With the second and third – which is to say, the two most recent states – we can dismiss the possibility of photo/reproduction variations because such could not be responsible for distinctly local changes, as with the dramatically and selectively darkened space between the little and the ring finger that occurred between 2007 and 2012. All three images are individually of a piece and speak of distinct appearances in the picture. Of the three states, the first (1988) is the one that is least like the others: its arm has two sharply defined contours and is slimmer than those in the other two photographs. To this photo-testimony, might anything be gleaned from what is known and what has been said about the picture?

Writing on the most recent (2012) state Natter speaks first of its reception and then of Klimt’s initial struggle: “Klimt wrestled long and hard with the composition and the standing motif, as his preliminary drawings testify… Only gradually did he arrive at the curvaceous, serpentine pose of the final portrait… Noteworthy is the dialogue between the figure and background…Such a permeability of natural forms and representations of the human figure is therefore thoroughly typical of Klimt…” (Emphasis added.)

Writing on the 2007 state, centre image above, Weidinger related the picture’s “erotic connotations” to Klimt’s “numerous snaky women who populate the symbolist paintings of 1898 to 1907” and held that, in this portrait, Klimt “emphasizes both line and area so as to produce a stylized rendering of the body such as manifested itself first in his Symbolist works…Instead of twisting three-dimensionally around her own axis, as do Mannerist figures [and Sargent’s “Madame X”] Rose von Rosthorn’s S-shaped body appears to be all on the same plane; the effect of this, coupled with the emphatic outlining, is to make the portrait seem curiously flat.”

There is a crucial difference in the two accounts. Where Natter speaks of the permeability evident in a dialogue between the figure and its background, he seems on safe ground with the borders of the extravagant fur stole and the lower body on the right, and with the division between the background and the assumed reddish chair, but there is no such permeability at the contour of the face and choker, or at the scissors-like fingers and chair back. Weidinger notes that the red of the armchair had been achieved with “the application of innumerable tiny brushstrokes, pointing in all directions at once” and that “the same method is used for the skin, although here the outcome is not so coarse”. The key difference in the two accounts lies in Weidinger’s recognition of Klimt’s deployment of both line and area. The line (which bounds impermeable shapes) is confined to the areas of bare flesh – the head neck and arm – where Klimt’s classically trained draughtsmanship asserts itself. In his commissioned portraits Klimt retained a respectful and more traditionally hierarchical attentiveness to the forms of heads and hands, whatever indulgence might have been given elsewhere to symbolism, pattern-making abstractions, and decorations.

The earliest photograph, above left is, by definition, the record that is temporally closest to the picture’s original appearance and it should, accordingly, be taken as a more reliable record than the two later states. Additionally, this 1988 state better accords with a vivid contemporary response to the painting. In contradiction of the present (post-2012) chilled blue background, Natter cites Frans Servaes’ captivation in 1901 with Klimt’s use of colour: “The shimmering violet of the background plays with tumultuous gentleness around the bare propped arm and the dark dress covered with spangles in the most wonderful fashion.” Today, one sees no violet against the arm in Figs. 19 and 20. A patch of background to the right of the dress might be thought of as violet but the larger cooler blue areas certainly could not. Might there have been earlier losses in the background as with those seen more recently in the hair? Natter also mentions that Ludwig Hevesi had been particularly struck by “Slender elastic lines having a singular swing, profile to the left…A slim pale arm supports itself on three fingertips on a piece of furniture; one realizes immediately that a figure such as this really does not need to support itself” – like that of an agile, super-fit rock climber, perhaps? Klimt’s final, working study, above left, had fixed the slim arm’s outer contour with deftness and precision. Such decisiveness of design in the arm is best seen here in the oldest record (1988) and is least evident in the most recent and most fumbled arm (2012) where the contours have succumbed to a havering state of permeability. To discount the 1988 photo-testimony in favour of the later states it would be necessary to claim that an earlier restorer had wrongly imposed an alien linearity on the arm and that in two successive restorations an original, fumbled and fatter arm had been recovered. The non-publication of the sole photograph by which this once lost painting was known is to be regretted.

VOID SPACE OR INTRIGUE?

To return to the Knips portrait, in both Figs. 16 above and 22 below it is possible to read miniature figures or statuary within the vegetation along a horizontal line to the left of Sonja Knips’ forehead.

Above, Fig. 22: Left, the 1908-14 collotype of Sonja Knips; right, a lightened section of the collotype’s left-hand area, in which the original two-tone ground/wall/shrubbery boundary is clearer. The above greyscale inset is a detail of a photograph carried in the October 1900 Figaro Illustré, as discussed by Emily Braun in the 2001 Gustav Klimt Modernism in the Making, Ed. Colin B. Bailey. In all three images the horizontal line of figures and a statue is discernible.

Above, Fig. 23: Top row, left, the 2007 Weidinger infra-red image; right, the 1908-14 Miethke collotype – in these, we indicate (in red) the moving ground/wall boundaries and the placement of the “window”. Below, in the centre group, we see how the reported figures had appeared in early photographs. In his 2007 rejection of earlier claims of perceptible figures in the picture’s upper half on the testimony of the infra-red image, Weidinger cites scholarly experts who had variously identified: “cupids and two figures…[a] pool and fish-like creatures… [and a] horse’s head…” Given such testimony – and the fact that discernible figures had registered in the dark background to the left of Sonja’s head in the Klimt-approved collotype and subsequent photographs to this day, as in Fig. 24, right below – those figures’ status might better have been resolved by the publication at high resolution of all the Belvedere’s photographs and technical records of the picture rather than with a dismissal by technical fiat on a single, out-of-context, difficult-to-read infra-red image.

The small, photographed free-standing Cupid sculpture in the centre group above is the former antiques shop find that has been upgraded and displayed at the Metropolitan Museum, New York, as an autograph early Michelangelo. If it might seem improbable that Klimt should have included secondary figures in a large and exceptional portrait, it could equally be held that the photographically-recorded figures in question were forerunners of the artist’s later incorporations of entire armies of people and horse riders – as in the above three later portraits of The Dancer (1916-17), left; Adele Bloch-Bauer II (1912), top; and Elisabeth Lederer (1914-16) bottom right.

Above, Fig. 24: The Portrait of Sonja Knips, as in 1908-14, left, and today, right, as seen in both colour and in greyscale.

THE DEMISE OF THE LILIES AND THE RISE OF “APPROPRIATE RESTORATION STRATEGIES” AT THE BELVEDERE

Above, Fig. 25: Three details of the lilies backdrop as recorded in: 1908-14, left; 1942-56, centre; today, right. In the inset, above right, a 1912 British Vogue fashion shot.

The differences seen above between 1908-14, left, and 1942-56, centre, are not substantial and might amount to little more than variations in reproduction values. The subsequent differences seen above, right, however, are of another magnitude and show outright losses of autograph material, as to the foliage between the upper arm and the back of the chair.

Above, Fig. 26: Left and centre, a two-page spread from Christian Nebehay’s 1969 Gustav Klimt, showing Sonia Knips in 2011 and her portrait when the hand/notebook motif was still intact; right, a detail from Johannes Dobai’s 1978 Klimt showing that by that date the hand/book had been injured and left incoherent. The offending restoration must, therefore, have taken place between 1969 and 1978. The picture itself was commissioned by Sonja Knips (1873-1959) and owned by her until 1950 when she was seventy-seven and it was bought by the Belvedere, Vienna. The museum says of its (manifestly hyperactive) conservation department:

“The Belvedere’s restoration and conservation department is dedicated to the preservation and care, restoration, and technological research into the art and cultural assets of the Belvedere’s collection, which ranges from the Middle Ages to contemporary art. Its mission is to record and preserve objects of historical and cultural significance. Conserving these irreplaceable originals requires a methodical and scientific approach in order to shed light on the historical, stylistic, iconographical, technological, and material aspects of the artworks. With this in mind, the Belvedere’s conservators devise appropriate strategies. On average, the department conserves and restores 150 paintings and frames each year, and frames and mounts between 100 and 150 graphic works.”

THE DECONSTRUCTION OF SONJA’S LITTLE RED BOOK

Above, Fig.27: The red leather-bound Klimt sketch book held by Sonja Knips, as seen, respectively in 1908-14, top; in 1956, centre; and today, above.

In this photo-sequence we see that crucial differences of appearance arose between 1956 and 2012 – in fact, on above evidence, between 1956 and 2007. Given the book’s changed appearances, Dr Natter’s claim that “The dualism of mimesis and dissolution, of faithful reproduction and painterly openness, is already in evidence here as a stylistic means” becomes problematic. Given that the once faithfully tight and precise book/right-hand had by then been left in a quasi-Cubist double image that resembles time-lapse photography, should it have been regarded as an instance of mimesis or dissolution? Natter’s view remains unknown because has not commented on the present condition. Such questions arise with other Klimt portrait pictures:

Above Fig. 28: Top, left, Klimt’s now lost 1900 portrait of the thirteen-years old Trude Steine (note the strong line of the shoulders); centre and right, a large detail of Klimt’s 1902 Portrait of Gertrud Loew, as in 1956 and today; above, a three-part chronological sequence of Klimt’s 1905 Portrait of Margaret Stonborough-Wittgenstein.

As a lost work, the Trudy Steine picture, will at least now never lose its great – photographically preserved – vivacity and force. Gertrud Loew disappeared when sent to Berlin in 1938. Her portrait survives but it has not been spared by restorers. Speaking to its condition today, as top right, Weidinger writes:

“Ludwig Hevesi [1902] referred to the portrait of Gertrud Loew – shown for the first time at the ‘Klimt Collective exhibition’ at the Secession in 1902 – as ‘the most fragrant lyric of which the painter’s palette is capable’. Like Serena Lederer the subject is clad in white. Colour accents are set by her long, downward cascading shawl with its lilac-coloured border. Klimt renders her pale skin in tones close to that of her dress, and only her red lips, blue eyes and dark hair supply the necessary contrasts. Her loosely flowing dress betrays no sense of corporeality. In this connection, Natter speaks of her ‘dematerialization’”. Weidinger adds that when exhibited in 1903 it had been said to possess “all the charm of radiant filminess” and “the gauziest lyricism of which the palette is capable.”

That was then. Restorers thought the filminess might be taken further and, to that end, simultaneously darkened the upper background and lightened the upper costume, thereby dematerializing the previously clear articulation of the subject’s shoulders. To add to the tonal mayhem, both the lower background and the lower dress have been lightened. This is no longer the picture Klimt painted of Loew. The Pirchan reproduction gives a truer account than the painting itself.

Above, Fig. 29: Main centre images: a detail of the picture as recorded in 1956 and today, in which sequence it is easy to identify the obliteration of leaves, multiple micro-losses of value in this dress and the loss/painting-over of the original foliage between the shoulder and the chair back; insets, a detail of one of Klimt’s preparatory studies for the painting; and (bottom left), a detail from a photograph of the portrait carried in the October 1900 Figaro Illustré (as discussed by Emily Braun in the 2001 Gustav Klimt Modernism in the Making, Ed. Colin B. Bailey).

Natter’s claim that Klimt camouflaged disparate pictorial means by simulating a photo snapshot holds fair insofar as Sonja grips the arm of chair firmly and (as others have noted) leans forward as if caught when about to rise, but the picture was no product of a snatched moment, as the many studies Klimt made of his subject when in costume and in the chair testify (see Fig. 30 below). It is also part-true that Klimt conjured a “fascinating contrast between the naturalistically modelled head of the sitter and the gauzy shimmer of her dress” (we are advised that the material was likely either very finely pleated silk chiffon or muslin) but, aside from the abundant skirt, there is no near-abandonment of corporeality: even in semi-repose this dress in animated and formed by the lithe, almost geometricized, body that was captured in Klimt’s preliminary studies.

Notwithstanding the abundance of small folds on the sleeves, the thin shapely taught-ness of the arm seen by Klimt and captured in the drawn studies had asserted itself in the painting. On comparing the above photographic sequence, it is evident that in the very earliest recorded state (1900, bottom left), the orchestrated collection of shadows at the bottom of the lower arm much better and more decisively “drew” the limb’s contour: at the turn of the sharply defined elbow there is first a discernible concavity and then a convexity that straightens as it runs down towards the wrist. That original taught-ness of form/anatomy and relative weight of shadow at the lower contour was also evident even in the small low-quality image from Nebehay’s, 1976 Gustav Klimt, shown above at Fig. 11, but, like so much in Klimt, it has subsequently been fuzzed and lost.

Above, Fig. 30: Some of Klimt’s many sketches for the Portrait of Sonja Knips, in every one of which the forms and the massing of the hair were noted in relation to the head.

Above, Fig. 31: Top, three photo-comparisons of details showing changes between 1956 and today; centre row, left, a drawing of Sonja Knips and a later photograph; right, a Klimt study for another painting; bottom row, Knips in 1956 and in 2007 (Weidinger).

More than a first foray into a new type, this arguably stands as one of Klimt’s best female portraits, its twenty-five years-old subject being utterly composed, beautiful, intelligent and with a resolute, if poignant gaze. As mentioned, having first seen Sonja to be gazing out of the picture, Susanna Partsch (“Paintings of Women”, Taschen, 2012) now sees a Gorgon-like demeanour with Sonja turning her head “so that she is looking out of the picture and fixes the viewer with her gaze”. That reading is not remiss on today’s appearance but in Pirchan’s 1956 image (here bottom left) the gaze seemed fractionally averted and the effect markedly more reflective than confrontational. Moreover, a comparison of the mouth’s two states shows that Sonja has received a fresh lipstick that no long conforms to the shapes and forms of her lips.

Partsch writes that “The curls of her hair are taken up in the ruffles of her dress” without noticing that the earlier softly disposed forms and luxuriance of the hair have been drained of form and vitality – as with the disappeared darkly accented shadow at the lower temple and cheek that formerly served to draw the contour of the face and drew attention to Knips’ right eye. Considering the importance of hair as a feminine adornment and how hard artists labour to do justice to its glories, it seems odd that clear injuries to it, as here and with Rose von Rosthorn-Friedmann alike, should generally go unremarked.

Consensual views break down on Klimt’s and Sonja Knips’ relationship. In the 2007 Neue Galerie book, Knips’s granddaughter, Dr Manu von Miller, author of Sonja Knips Und Die Wiener Moderne, 2004, reports (“Embracing Modernism, Gustav Klimt and Sonja Knips”) that recently disclosed materials from the Knips family revealed much about Sonja and shed light on previously unknown aspects of Klimt’s life and person. Thus: Klimt’s Sonja portrait “likewise contains hints about the life of the artist” and that the two had had an affair years before it was painted, Klimt having known her since she was a teenager. Painting Sonja had released Klimt from his role as “a ‘decorative’ painter”, and he in turn enormously influenced Knips enabling her to “break free of the rigid bourgeois conventions of her time, and to create her own highly personal approach to aesthetics and collecting.” In 1896 Sonja married the industrial magnate Anton Knips – a mismatch, he not sharing her passions for socialising, modern art and young artists. Klimt’s relationship had, Dr Miller reported, “blossomed at some point into an amorous relationship. How long the affair lasted is not known but Gustav and Sonja’s romance is substantiated by notations on a paper fan found among Sonja Knips’s personal effects.” Those included a love poem dated 1895, the year before Sonja married Anton. A member of her family had told Miller the affair ended because Klimt was unwilling to marry her. The fan was thus “a love note and a farewell”, Klimt having ended another affair in the same manner…and given that Sonja sat for Klimt’s portrait scarcely a year after her wedding, Miller felt “It is hard to imagine that the painting could have been produced without their recent love affair being in the minds of both artist and sitter. She may have viewed the portrait as an enduring reminder of the relationship; it was noted by an acquaintance of Sonja’s that her eyes would light up when she was asked about the history of the painting’s creation.”

As mentioned, Sonja Knips kept the painting until her seventy-seventh year and, as Miller noted, she purchased Klimt’s unfinished (and highly erotic) Adam and Eve after his death and hung it “in the small boudoir next her bedroom”. Partsch will have none of Miller’s account, writing (Taschen, 2012): “On the basis of this fan and the decoration on the reverse side, Manu von Miller reconstructed a love affair between Gustav Klimt and Sonja Knips before her marriage and proposed that Klimt used the fan as a way of ending their relationship. Miller also suggests that Klimt may have done the same with a second fan destined for an unknown recipient and on that occasion carrying the German proverb… (‘Best to get unpleasant things over and done with’) … It is my view that the fan belonging to Sonja Knips points neither to a love affair between the artist and his model nor to a rupture between the two. Rather, it shows Klimt expressing his congratulations to Sonja Knips upon her engagement…”

What then, to make of the prominently displayed (- almost at the picture’s geometrical centre) little red book? In 1992 Nebehay wrote of “a small red notebook: a sketchbook that Klimt gave her.” It had been found in Sonja Knips’s estate and edited by Nebehay and was one of only three such surviving notebooks. It contained a small photograph of Klimt. Alice Strobl had dated Klimt sketches in it to between 1897 and 1899. Strobl had reported an eyewitness’s recollection of Klimt’s studio floor “strewn with thin red notebooks in which he jotted his artistic ideas down in shorthand, as it were.” Nebehay notes that Klimt was as disorderly with his notebooks as with his sketches which lay about in heaps on the floor.

On the book’s possible significance, Nebehay, like Partsch, leaned towards scepticism: “A married society woman would never have dared keep anything that was more than a souvenir” and, he went on, “Johannes Dobai reports that the lady [Knips] told him that the figures hidden in the foliage behind her had no symbolic meaning and as for the notebook in her hand, that was chosen for the colour effect.” Against that, Weidinger wrote in 2007:

“During his second series of studies, Klimt appears to have wanted to portray Rose von Rosthorn-Friedmann holding a rose in her right hand, but in the final version decided against this. The little sketchbook Sonja Knips is portrayed holding serves a similar purpose. Her claim that Klimt had merely wanted to add a shot of colour can be refuted on the grounds that the book appears in the studies for this work as well. Klimt is clearly using the book as an attribute which he considers apposite.”

Alma Schindler who so jealously and angrily cited Klimt’s affair with Rose had been delighted when Klimt preferred to make a new fan for her rather than contribute to a fan gifted by another man. Klimt pursued Alma as a teenager and was greatly distressed when prevented from initiating an affair with her. Klimt, as mentioned had known Sonja, too, as a teenager before her marriage. If the presence of the book is to be discounted, what of the picture’s part-hidden Cupid and figures and why have they been so uniformly dismissed on the sole testimony of a technically penetrating image?

Partsch contests an affair against much evidence and trusts an infra-red image: “The dominant field of blackish brown, which provides a foil to the flowers and the female sitter, contains several lighter patches. These have inspired numerous interpretations… [which infra-red photography] has failed to confirm…” In 2008 Rachel Barnes (Gustav Klimt) wrote: “There was a theory that Klimt painted a number of things in the background, including a horse. Subsequent infra-red examination has proved this was not the case.”

It is unfortunate on many levels that in modern times scholars turned from artists to restorers for guidance on technical and aesthetic matters when restorers have no technical means of analysing artistic values and, through their interventions, so repeatedly demonstrate inabilities even to recognise and respect them. It seems that nothing might arrest their long march through the world’s art – no matter how egregiously they mangle its images and, hence, meanings. We live in hope that owners and scholars will better defend the integrity and dignity of works of art but note that we first complained of restorers’ manifestly and indefensibly destructive actions – and of art historians’ effective complicity – in an article, “A crime against the artist”, in The Independent of 22 November 1991 as reproduced below at Fig. 34:

The Sistine Chapel Restorations, Part III: Cutting Michelangelo Down to Size

27 May 2013

“Judging by Past Experience, it is Perilous to Suggest Restoration…”

~ Charles Heath Wilson, 1881, “The Life and Works of Michelangelo Buonarroti”. Publisher: John Murray, London.

“I once barged into a correspondence in The Times when the National Gallery was under fire from the ‘anti-cleaners’. I was ticked off very severely by Lord Crawford, the Chairman of the Trustees. I had, mildly I thought, criticised the authorities for ignoring the sincerely held views of the opposition…I was later restored to favour in high places when I made it clear in an article in The Studio that I was convinced that our National Treasures were in the keeping of qualified responsible people.”

T. J. Honeyman, 1971, “Art and Audacity”. Publisher: Collins, London.

It is not widely appreciated how inherently dangerous art restoration practices remain, or how culturally deranging restoration changes can be. At the bottom end of the trade, restorers often advertise their services on a promise to leave pictures “as good as new – or better”. The restoration of Michelangelo’s Sistine Chapel ceiling was – on the accounts of its own restorers and initiators – the biggest, the best, the most scientifically advanced and “radically transforming” top-end restoration ever undertaken. This “Restoration of the Century” left one of the world’s greatest artistic accomplishments so profoundly unlike its former self that enthusiasts could announce the discovery of a “New Michelangelo” who was “very different from the one art experts thought they knew”. At the same time, the chief restorer thrilled in 1982 that the frescoes looked as good as new: “as though they were executed yesterday”. In the midst of this commonplace restorers’ confusion between “recoveries” and “discoveries” (or sometimes, “revelations”), some surprising expressions of support materialised. In 1987, a top-end art historian writing in the magazine Apollo [Endnote 1] announced the demolition of the “Darkness Fallacy and the Sculptural Fallacy” within Michelangelo scholarship, and predicted that the then concurrent restorations of the Sistine and Brancacci chapels would leave both Michelangelo and Masaccio as “less isolated geniuses” who would be “returned to their respective periods” (i.e. confined within designated art historical boxes). In 1991, a newspaper art critic exulted in the displacement of “doomy outpourings of religious angst” by colours as “bright as Opal Fruits” – which colours reflected the workings of a “much more rational mind” [2]. Unsurprisingly, such professional pleasure-taking in chemical transformations that could cut artistic Titans down to size alarmed those who had been happy with the surviving Michelangelo, and an enormous controversy arose. Unsurprisingly, the criticised characterised the criticisers as instances of “the magnitude of the shock to entrenched opinion” that had been unleashed by a triumphant restoration. (As will be seen, the expression of sincerely held citicisms can be harshly punished when substantial vested conservation interests are challenged.)

Behind this interpretive culture war, the effects of the restoration on Michelangelo’s art were material and aesthetic. Those changes are forever. Although bad scholarship can be remedied by good scholarship, the latter cannot undo damage to unique, historic works. What remains to be done, a third of a century after the restoration’s 1980 launch, is a proper, disinterested aesthetically informed analysis of the restoration-induced changes, item by item, figure by figure, photograph by photograph; and, a frank evaluation and acknowledgement of their cultural and art historical consequences. Had this restoration’s profound transformation been accepted without challenge, we would be in a world today where technicians enjoyed unfettered licence to rewrite (or as they sometimes prefer, “to re-present”) history itself. Even tacit endorsements of injurious restorations can damage scholarship and falsify history.

The restoration of Michelangelo’s Sistine Chapel ceiling was well and publicly defended from 1980 until the mid 1990s. At that period, a seismic shift occurred. What follows is an examination from a British perspective of the restoration’s defences up to 1995 (in which year implicit art historical support for the restoration resulted in a seriously misleading exhibition at the National Gallery); and, a further presentation of visual proofs of the restoration’s injurious consequences. We note here how many supporters have admitted entertaining doubts about the restoration’s probity.

A new cleaning method, and the selling of a “New Michelangelo”

In the 1980s, at the height of an international restoration mania, a supposedly “advanced” “scientific” cleaning material was used on Michelangelo’s Sistine Chapel ceiling. It was ferocious in its effects and mechanistic in its application which was expressly designed to thwart personal and allegedly “subjective” and “unscientific”, aesthetic appraisals. The most sophisticated imagery on an immensely important historic work of art was thus subjected to a “treatment” that derived not from the complexities of picture restoration and its necessary acts of discrimination and constant evaluation but, rather, from architectural stone cleaning techniques. This cleaning method altered the ceiling’s centuries old artistic/historic continuity to such a degree that the restorers and their supporters ventured that history would need to be rewritten. The changes, for sure, were dramatic: depictions of figures that had been archetypally and transcendentally alive were brightened, flattened, rendered more abstract, more “on the picture surface” and left with an altogether more modernist and imaginatively impoverished aspect. Contrary to official claims this (demonstrably) was not a liberation or recovery of the ceiling’s original condition and appearance – see, particularly, Figs. 1 and 60.

When Michelangelo’s ceiling was unveiled in 1512 the world was stunned by the grandeur, pictorial audacity and, above all, by figural inventions that had rendered the divine corporeal and vividly alive within our own space and time. Michelangelo had not so much made depictions-on-surfaces as conjured perceived spaces adjacent to the ceiling’s imperfect forms. His optically “sculpted” spaces – which opened vistas beyond the ceiling’s surfaces while simultaneously projecting figures in front of them – had been realised through powers of draughtsmanship and modelling with utter disregard for the “integrity” of the architectural surfaces. Seemingly palpable space was necessary to situate Michelangelo’s monumental programme of over three hundred figures – figures that ran from depicted carved stone sculptures (his architecture-adorning putti), through living, space-occupying young sculptural Adonis’s (his contorted, anxious ignudi) and, more prosaically, through the historical ancestors of Christ, to the divinely gifted Prophets and Sibyls, and finally to God Himself and his celestial supporters. This was immediately acclaimed as a dazzling artistic and illusionistic advance. Its eventual influence was to carry mural painting into the Baroque and beyond. Although artistic fashions and modes of description change constantly, for nearly five centuries this “stupendous” work’s vital relationships endured, as the many copies made throughout its existence testify (see Fig. 1b).

How Doubts became Denials

With the restoration of Michelangelo’s Sistine Chapel ceiling, while some art world players were galvanized into opposition, many others were excited and swept along by the presumptuous magnitude of the transformation. As mentioned, many of the supporters of the restoration have disclosed moments of doubt. We cited in our post of March 4th that the co-director and chief restorer of the ceiling, Gianluigi Colalucci, had said in 1990: “I must confess I harbour a lingering almost subconscious fear that someday someone will come, unexpectedly, with a really intelligent observation that will show all of us to have been blind.” The following year the Sunday Times art critic, Waldemar Januszczak, produced a celebratory book (“Sayonara Michelangelo”) in which he asked in the face of the transition:

Who among us looking up for the first time at this new, bright, clear Sistine ceiling, perfectly rational, a light-filled work, was not tempted by the doubt: it can’t be so.”

This temptation was throttled by the sheer spectacle of the restoration as an art-changing performance:

The thin and neat scaffolding bridge moved elegantly along the ceiling like a very slow windscreen wiper. In front of it lay the old Michelangelo, the great tragedian, all basso profundo and crescendo. Behind it the colourful new one, a lighter touch, a more inventive mind, a higher pitch, alto and diminuendo. It was being able to see both of them at once – Beethoven turning into Mozart before your eyes – that made this restoration such a memorable piece of theatre.”

Even the National Gallery’s thoughtful and scholarly (then) curator of Renaissance painting, Nicholas Penny, who recognised (“White Coats v. Bow Ties”, London Review of Books, 11 February 1993) that “The most terrifying thing about the restoration of old paintings and sculpture, as distinct from the editing of texts, is that something might be lost altogether”, swallowed his own moment of anxiety:

But perhaps one should admit that something is lost however much is gained by any intervention – some possibility of interpretation if not some actual pigment or glaze or polish.” [Emphasis added.] With a seeming acceptance of such material and interpretive losses, the greater gains in the Sistine Chapel were said by Penny to have emerged as follows:

Study of the ceiling now that it has been cleaned tends to distance Michelangelo from the art of recent centuries – and from the work of artists who were inspired by the ceiling – and reveals a far closer connection with the dazzling colours favoured by artists in his immediate following and also evident in some of the better-preserved 15-century Florentine panel paintings.”

Note the cultural role being served by “restoration” changes: even when their legitimacy is vehemently challenged, restorations facilitate through “study”, new interpretations and a certain re-shuffling of scholarly furniture. Scholars and restorers invariably say that they have duly considered and rejected the criticisms as ill-informed, but the fact remains that eventually all restorations themselves come to be rejected and undone by later restorers. Indeed the alleged need to undo previous restorations is one of the commonest justifications for a restoration. The net consequence of repeated restorations is not a return to an original condition each time, but a daisy chain of altered alterations, with each successive restoration leaving the given work looking unlike its previously “restored” state. With accumulating alterations, works get thinner and thinner. Insofar as such abraded appearances are acknowledged, they are attributed to previous “rubbing”, or other euphemisms. Losses of original material during restorations (as Penny conceded) are to some degree inevitable. This is because while painters work from supporting canvases or panels upwards, restorers work downwards with their solvents and abrasives towards or beyond pictures’ finished surfaces. Collisions are inevitable.

The “New Michelangelo”

The art historical revisionism that advanced with this restoration might have been plausible had changes of colouring been the only changes, and had any of Michelangelo’s contemporaries noted dazzling colours. By any properly visually alert appraisal, however, the changes were less ones of enhanced chromatic power than of debilitating losses to the ceiling’s initially celebrated dramatic modelling and lighting (see Fig. 60). Although Nicholas Penny acknowledged such objections to the received critical consensus, he nonetheless caricatured them:

Polemics against the restoration appeal repeatedly to the ideas of chiaroscuro and harmony as artistic absolutes.” The implication that critics were in the grip of a fetishized false artistic consciousness was underscored: “It is painful but important to acknowledge that the inspiration one artist draws from another, earlier one is often inseparable from misunderstanding.” It is a common defence against critics to allege some “misunderstanding” of the “facts” because of ingrained or entrenched prejudices but with this restoration the objections stemmed not from misapprehensions or misplaced adherence to ahistorical idée fixes, but from the fact of the concrete, demonstrable and historically verifiable injuries to the painting.

Further Material Evidence of Injury

Having shown many directly comparative pairs of “before” and “after” restoration photographs as proofs of injury – we further present seven single photographs (Figs. 1 to 6 and 48b), each of which alone testifies to the destruction of the final stages of Michelangelo’s painting. To pinpoint the unsoundness of the restoration’s theoretical underpinning, we also show two other works, one drawn (Fig. 41), one painted (Fig. 47) that seem emblematic of serious critical neglect. It will be argued that insufficient respect for the artistic and documentary records (particularly in the form of graphic copies and related paintings) facilitated an initial misdiagnosis of Michelangelo’s painting methods. In addition, we examine the “macro” consequences in terms of changes to the previous relationships between the broad and differentiated zones of the Sistine Chapel’s consecutively decorated surfaces.

Selling the Restoration and Blocking the Critics

In December 1987 two articles that acknowledged the intensity of the controversy were published in Britain. One was a work of journalism by a leading cultural writer with strong interests in science, Brian Appleyard. The other was a full-blown and frankly declared Public Relations Apologia by Kathleen Weil-Garris Brandt, a professor of art history at New York University, a consultant member of the Vatican’s Scientific Advisory Committee on the restoration, and the Vatican’s spokesman on “scholarly and general information” for the public relations firm Arts and Communications Counsellors, which had been retained to handle the crisis.

To take the former first: on 20 December 1987 the Sunday Times magazine carried an article on the restoration – “Lost or Found?”. Its author, Brian Appleyard, acknowledged that he had been “carefully and elaborately briefed” by the co-directors of the restoration, Fabrizio Mancinelli, the curator of the Vatican Museums’ modern paintings, and Gianluigi Colalucci, the head restorer, and by Professor Carlo Pietrangeli, the director of the Vatican Museums, and that the next day he had been “scientifically persuaded” by the Vatican’s chemist, Nazzareno Gabrielli. Nonetheless, Appleyard gave a fair and balanced account, citing the arguments of James Beck, a professor of art history at Columbia University, New York. Even while recognising that “the vast majority of art historians are on the side of the Vatican”, Appleyard concluded “So far the Vatican have been troubled by Beck but have been secure behind the battery of art historians prepared to stand up and oppose him. But his fury and energy are beginning to pay off. More and more awkward questions are beginning to be asked and he warns of more home-grown opposition in Italy.”

An Artist Thwarted

The article itself prompted controversy in Britain by including directly comparative before and after restoration photographs of sections of the frescoes. To this artist’s eyes, those photo-comparisons showed instantly that the “cleaning” was damaging and that the protests were well founded (see Figs. 9 to 11b). Working then as the principal illustrator of the Independent, a new and fashionable newspaper with excellent arts coverage, I asked the arts editor if I might write a short article demonstrating the ways in which the ceiling was being damaged. He declined on grounds that the newspaper’s art critic, Andrew Graham Dixon, had (like Beck) visited the scaffolding, and had been persuaded (like many art historians and critics) that all was fine.

Thus, the first lesson in this controversy was that an artist who had trained for four years in a junior art school, for five years in a fine art college and for three post-graduate years at the Royal Academy Schools – and who afterwards had taught and practised drawing and sculpture for fifteen years – could be unvoiced in a debate about the treatment of a work of art in deference to the views of someone sixteen years younger who had read English at university and art history at the Courtauld Institute (- on which institution’s restorations see “Taking Renoir, Sterling and Francine Clark to the Cleaners”).

An Artist Heeded

When the Independent launched a Sunday edition in 1990, its arts editor invited an article on the Sistine Chapel restoration. In preparation, I contacted James Beck who put me in touch with many key critics. These included, in Italy, Professor Alessandro Conti, Venanzo Crocetti, the sculptor who had worked on the previous restoration of the Sistine ceiling in the 1930s, the restorer Mirella Simonetti; and, in the US, the critic and writer Alexander Eliot and the painter Frank Mason. From the Independent on Sunday I spoke directly to Professor Brandt, Dr Fabrizio Mancinelli, Professor John Shearman, (an advisor to the restoration who viciously attacked Beck on the record and then threatened to sue if I published his grossly defamatory comments), and wrote to Gianluigi Colalucci. The second lesson had thus been that critics of restorations, however prestigious, could find themselves victims of scurrilous attacks from professional peers.

Shooting the Messengers

When surveying the restoration’s then decade long literature, Brandt’s 1987 Apollo article emerged as a seminal document. Its declared purpose had precisely been to defend the “transformation of Michelangelo’s mysterious dark frescoes…into [the] blazing colouristic pyrotechnics that is attracting the most public attention and controversy” (this was despite the fact that Michelangelo had been praised at his own funeral for “the fleeting and sombre colours with which he had formed such rare and lofty shapes”). Most striking of all was Brandt’s assaults on the restoration’s critics, whether they were scholars, restorers, traditionalist artists or fashionably modish artists:

“But, a tiny, heterogeneous and vociferous cadre emerged with the dramatic charge that Vatican conservators are ruining one of the great icons of western civilisation. “Convinced of the urgency of their mission, the critics conducted their campaign in the international press and television and achieved a remarkable degree of public visibility. A letter by a well-meaning group of American master painters of the Pop generation, calling for a halt to the cleaning of the Sistina (as well as the Last Supper) was one index of their success. An interview with one of the American Sistina critics in People Magazine was, however, another… “To the ears of most art historians and conservation experts, however, the critics claims sounded more and more like the wild cries of some ferocious mutant of Chicken Little. Many believe that the critics, like that benighted bird, were misunderstanding insufficient evidence to draw mistaken conclusions to the alarm of the neighbours. Still the issue is a serious one. Are the critics merely opportunists, body-surfing on a wave of publicity they would never otherwise have enjoyed? Or should we be hearing in their polemics a warning that the cleaning of major works of art is another of those matters too important to be left to the experts?” “If the critics’ questions have such detailed answers, what is the continuing public fuss about? Why has the criticism been so remarkably vague, shifting and misinformed? Why have the critics been so reluctant to make the frequent visits to the Sistine Chapel scaffolding…Why does criticism remain invulnerable to the abundant available information. How could such a small group of people, none of whom is – in a professional sense – an expert on Michelangelo and conservation, attract so much publicity and even some well-intentioned adherents? (The original nucleus of nay-sayers consists of only five persons: two painters, one former art critic and two art historians, distributed in Italy and the USA; connexions between them exist but are hard to define.)”

In addition to an insinuation of some underlying conspiracy, Brandt appended an imputation of political motivations that served as platforms for personal opportunism:

“It is easy to see how any hint that the Vatican might be hurting Michelangelo could fuel political fires while providing a chance for professional power play among factions of the intellectual establishment.”

If political motivations combined with personal power play might exist among critics in Italy, Brandt maintained, the situation was different in the United States where:

“The continuing publicity has, of course, also become a phenomenon in itself with a life and fascination of its own. All the more significant that only one American scholar has been tempted to join the public furore. “None of this grandstanding matters much – although one doesn’t like to see an important issue distorted and people misled. I do not believe that a tenacious campaign of ill-informed criticism and personal attacks on the conservators will stop the careful cleaning of the Ceiling.”

Traditional Slurs

At this historical point Brandt’s past abuse of the critics might best be taken to have been self-answering. Her assurance that “the cleaning chemicals do not actually come into contact with the fresco surface” has not worn well and, besides, was at odds with the chief restorer’s earlier admission that if left on a minute too long the chemicals began devouring the fresco surface and Michelangelo’s shading with it. Similarly, her claim that the restoration had been “spurred by the alarming discovery that the glue layers were contracting as they aged , and were pulling flakes of plaster and pigment away from the surface of Michelangelo’s frescoes” proved an impermanent position. As was later reported in “Art Restoration, The Culture, the Business and the Scandal” (James Beck and Michael Daley, 1993), it had been claimed in 1986 (six years into the restoration) that “various checks [had] ascertained that in several places minute flecks of colour were lifting” and that this had “necessitated an immediate restoration.” In 1987 it was said that extensive areas of flaking were progressively worsening and threatening an imminently “uncontrollable situation”. By 1988 Vatican spokesmen were claiming that the weight of encrustations upon the paint surface was causing it to break away from its ground. By 1989 it was said that the glues had “shrunk and puckered” causing “scabs” to fall away “pulling pigment with them”. It was said that this “slow destruction by glue-pox” was “the Vatican’s principle motivation for cleaning the ceiling”. When we asked Brandt in 1990 how big the puckerings were, she replied “Oh! Some are as big as your hand.” Soon after, in 1991, the problem de-escalated: initial investigations were acknowledged, once more, to have encountered “minute desquamations and loss of pigment.”

Brandt’s patronising claim that “the so-called ‘controversy’ is not actually about facts and issues but is a reflection of culture shock” lamely echoed charges made in earlier restoration controversies. During the National Gallery cleaning controversy in London in the late 1940s the critics were said by the art critic, Eric Newton of the Daily Telegraph, to be suffering from the “shocked eye”, a condition which afflicted “the connoisseur and the artist – the visually sensitive man with a quick eye and profound reverence for what he had seen”. Just as at the Sistine Chapel, Newton’s dismissal of the expertise of creative players was made on the claimed authority of restoration “science”. Such generalised appeals to the authority of science often prove to be empty incantation and Newton volunteered no more than “The purely scientific and technical aspects of the process, however are too complex to describe here.”

In 1857 picture cleanings at the Louvre were defended on the grounds that “It is understandable that the romantic amateur loves the rust and the haze of the varnish, for it has become a veil behind which he can see whatever he desires” (Horsin Déon). One critic of the Louvre’s restorations, Edgar Degas, threatened to produce a pamphlet that would be “a bomb”. When Brandt dismissed the Sistine Chapel critics on the grounds that the controversy was “rather unreal since the arguments against cleaning are mainly nostalgically emotional [while] those on the other side are chemical and scientific” she presented her role as being to “dissolve some of the murky argument and preserve a few facts”. As will be seen, artists and art historians can have distinctly differing views as to what constitutes a “fact” and what a blind prejudice.

The Evidence of Restoration Injuries – and the Surprising Reactions To It

When the Independent on Sunday’s picture desk obtained high-quality colour transparencies from the Vatican in 1990 we examined the image of the Erythraean Sybil, part of which had been shown in Appleyard’s Sunday Times article, and encountered among many losses the restoration-mangled foot seen at Figs. 2 and 3. Those losses and losses to a figure on one of the lunettes were first published in the Independent on Sunday of 25 March 1990 (see Figs. 12, 13 and 14) and then later in the Independent of 20 March 1991, where the arguments against the restoration were put by Daley, Beck, Conti, Eliot and the art historian Bruce Boucher, and balanced by three counter arguments.

Of the latter, Ernst Gombrich was harshest on the critics: “No one is infallible, but I have not the slightest doubt that the overall impression and operation is right, and the critics talk absolute nonsense.” The Courtauld Institute-trained editor of The Art Newspaper, Anna Somers Cocks, condescended that some people liked things to look “romantic and old, and can’t cope with the clarity and brilliance of what the Sistine Chapel looks like now it has been cleaned”. The Courtauld Institute-trained Nicholas Penny said “It’s one of the great revelations of our time but the transformation is so absolutely amazing that it is bound to give some people a shock and I am sympathetic to them being shocked”.

Brandt’s 1987 Apollo account had fallen on well-worked ground in Britain where even art world players with strong track records of being critical of restorations had become supportive of this restoration. The Courtauld Institute-trained restorer Sarah Walden, who had implicitly criticised many of her peers and predecessors in her 1985 book “The Ravished Image ~ Or How to Ruin Masterpieces by Restoration”, was one such and she offered this (simplistic) technical distinction in defence of the restoration’s results:

Unlike easel paintings, frescos are not a film of paint on a surface but impregnate their own support and need no varnish. Given an intact, dry wall, they are spared many of the rigours of restoration, except for the removal of dust and dirt. As the recent cleaning of Raphael’s Galatea in the Farnesina in Rome has shown, and as the present work on Michelangelo’s Sistine Chapel seems to confirm, this is one area where impressive results can be had with far less risk.”

As shown on 28 April 2012, the restorer Leonetto Tintori had discovered on examining the ceiling that it had been covered by what he termed “Michelangelo’s auxilliary techniques” which included not just glue or size painting but also oils. Walden, whose principle critical complaints had been against the “Anglo-Saxon” schools of restoration in Germany, Britain and the US, as opposed to the “Latin” restorations of France and Italy [3], had evidently accepted the restorers’ claims that Michelangelo had simply coloured successive patches of wet and drying plaster at great speed and thereafter accepted whatever disparities and inequalities of value emerged on drying without making any unifying or enriching interventions with glue-based painting a secco on his fresco surfaces when dry, as was customary and as had been noted by his contemporaries. She had further accepted the restorers’ (revisionist and unsupported) claims that the large amounts of glue-based material on Michelangelo’s frescoes had been applied by restorers as a “varnish” to a work which, on her own account, would have required no varnish, and despite the fact that previous Vatican restorers had attributed that very material to Michelangelo. Gombrich, who had played a prominent role in the post-war cleaning controversies at the National Gallery in London – and who had written the Foreword to Walden’s book – was similarly persuaded by the present Vatican restorers’ well disseminated technical account.

Gombrich’s Startling Lapse of Scholarship and Visual Acuity

In 1995 Gombrich presented an exhibition, “Shadows: The Depiction of Cast Shadows in Western Art”, at the National Gallery (London) on the thesis that an avoidance of cast shadows had been “widespread among painters of the High Renaissance”. He did so without reference to the paintings of Michelangelo or Raphael. (When pressed on these omissions he replied “I never meant [the catalogue] to be an encyclopaedia of all cast shadows, though some of my readers seem to assume so.” – Letter to Michael Daley, 10 June 1995.) As will be shown, in a curious fashion, Gombrich’s pictorial amnesia constituted the logical terminus of a more general denial by art historians of the distinctive artistic relationships that had survived on the pre-restoration ceiling, and of the connections between those relationships and the art forms of the period and immediately afterwards. Defending this restoration became an exercise in not-seeing what was and what had been. Gombrich’s position on this restoration was a great disappointment to us given his outstanding earlier contributions.

Gombrich on the Sanctity of Scholarship

In 1978 as the Vatican Museums’ curators, restorers and scientists were moving towards restoring the Sistine Chapel ceiling, Gombrich had discussed one of Michelangelo’s prophets – his Ezekiel – in the context of problems of art connoisseurship and medical practices (and with no reference to colour) [4]. He pointed out that just as with placebos “suggestibility plays a part in our response to works of art”. Demonstrating by a comparison between Jeremiah and Ezekiel that the latter was uncharacteristic of Michelangelo but characteristic of Raphael, he firmly attributed its execution to Raphael (see Fig. 25). Of all the prophets on the ceiling, he contended, this one alone lacked Michelangelo’s profound stylistic traits: “he always negates the picture plane. Jonah being the most famous example of this space-creating and surface-denying imagination, which so aroused the admiration of Renaissance writers.” How could it have been overlooked, Gombrich continued, that the Ezekiel, far from denying the picture plane, asserted it: “Instead of being self-enclosed it impetuously moves to the right, addressing an unseen partner in what looks like a violent argument. It is this implied movement which tears the cohesion to pieces and introduces a shrill note of drama entirely absent from the other creations. The composition is only superficially Michelangelesque…” Further, what the Ezekiel betrayed in its agitated gestures was Raphael’s own great indebtedness to Leonardo: “Indeed it is hardly too much to say that Ezekiel would fit comfortably into the groups of the apostles in the Last Supper of S. Maria delle Grazie.”

This was vintage Gombrich, learned, conceptually adroit, visually acute and boldly re-attributing a Michelangleo to Raphael through Leonardo. Except that here his elegant arguments and persuasive stylistic “evidence” amounted to no more than a plausible contrivance – a conceit that was, he confessed, an art connoisseur’s equivalent of the medical practitioner’s placebo. He hoped that connoisseurs “will not take offence and that the spirits of Michelangelo and Raphael will forgive me this harmless fabrication.” (Was that jest to become a maquette for a far greater and undisclosed prank on those two great artists seventeen years later?)

Gombrich and the Guardians of Memory

Two decades earlier, in a moving 1957 essay “Art and Scholarship”, Gombrich had championed the scholar as “the guardian of memories”. It seemed that he had been stung to do so by the painter Wyndham Lewis who had recently written:

When I see a writer, a word man, among a number of painters, I shake my head. For I know he would not be there unless he was up to something. And I know that he will do them no good…”

Gombrich’s retort was: “Why should the artist bother about that spoilsport the scholar and his past? The brief answer to this question, I fear, may sound moralistic. Because truth is better than lies.”

Indeed it is – but this leaves his own later omissions in the National Gallery exhibition the more perplexing: How could so great a scholar make so seriously misleading and unfounded a claim in (seeming) defence of such an unsupportable restoration? Spicing this mystery is the fact, as shown below, that Gombrich’s faith in the Sistine ceiling restoration was not absolute and that he, too, like Colalucci, Januszczak and Penny, had once acknowledged a moment of doubt.

Gombrich’s Moment of Doubt

As mentioned, Gombrich was as one with the views of the restorer Sarah Walden on this restoration. Walden was to persist with her endorsement of the restoration until at least 2004 when, in a revised edition of her book (now titled “The Ravished Image ~ An Introduction to the Art of Picture Restoration & Its Risks”), she pressed Gombrich into a swipe at critics of the Sistine ceiling restoration:

The subject of restoration tends to attract cranks and fanatics, but to suggest that the world’s foremost art historian was one of those would be absurd. He approved for example of the cleaning of the Sistine Chapel, and wrote to me about an Italian who opposed it and was seeking his support: ‘Of course he wants to use [my writings] as ammunition against the cleaning of the Sistine Chapel, but I do think the problems of cleaning are different…I have been up the scaffold…I have no doubt that the team are aware of the many problems…I am even fairly happy about the work on the Sistine ceiling.’” [Walden’s ellipses.]

While Walden tactfully refrained from identifying the Italian critic, by publishing a letter she received from Gombrich in 1987 in the revised book, she revealed an intriguingly confessional remark:

Last week I was sent a book from Italy violently attacking the ‘cleaning’ of the Sistine ceiling. It may contain some exaggerations but it is still disquieting. Michelangelo e la Pittoria a Fresco, by Alessandro Conti (La Casa Usher, Florence 1986). If you read Italian and have a little time during the next few weeks I’ll gladly lend it to you to look at.”

That unsettling book was later described by Penny in the LRB as “the most sustained polemic against the restoration”. Charles Hope, an authority on Titian and then the Senior Lecturer in Renaissance Studies at the Warburg Institute, London, wrote (in a letter of 1994 to the restorer Helen Glanville – see below) that “The scholar who has done most to draw attention to the relevant texts is of course Conti; and whatever you think of his book (he is not a restorer, by the way), I am sure we can agree that it is obligatory reading for anyone interested in the controversy surrounding the ceiling. Yet […] and so on not only pass over his arguments in silence instead of addressing them, they seem never to cite his book at all…” Gombrich, too, would seem to have suppressed his own disquiet and passed over Conti’s arguments even though he must have appreciated that Conti was a very considerable authority on restoration having taught the History and Techniques of Restoration at the University of Bologna; the History of Modern Art at the state university in Milan; and, the History of Art Criticism at the University of Siena. In his 1988 “History of the Restoration and Conservation of Works of Art” (republished by Butterworth in a 2007 English translation by Helen Glanville) Conti spoke of the alien “material and chromatic robe” with which the Sistine ceiling paintings had been invested “during the present restoration” and identified “the various media” Michelangelo had used on the ceiling as “fresco, lime and secco”. (For Conti’s further comments in that book on Domenico Carnevale’s repairs to Michelangelo’s ceiling, see the caption at Figs. 48a and 48b. That his now very scarce Michelangelo e la Pittoria a Fresco has yet to be published in English might itself be thought something of a scandal.)

The Context of Gombrich’s National Gallery Exhibition

Gombrich’s 1995 exhibition came not just towards the end of his long and distinguished career but at the end of a brief period of intense discussions in Britain on the restorations at the Sistine Chapel and the National Gallery. We had been at pains to show that extreme as the Sistine Chapel restoration was, it was part of a wider radically transforming international assault by restorers acting on historic works of art in the name of their “conservation”. (Between 1990 and 1995, this author alone had published twenty-three times on those subjects – see Fig. 12.) Such discussions greatly accelerated with the publication of the 1993 Beck/Daley book “Art Restoration ~ The Culture, the Business and the Scandal” which, in addition to two chapters on the Sistine Chapel carried a chapter on the National Gallery’s restorations. Responses to the book were various and sometimes startling. They prompted an additional chapter, “The Establishment Counterattacks”, in the revised 1996 American paperback edition. We should acknowledge here that the National Gallery, under its present director, Nicholas Penny, as initially under its previous director, Charles Saumarez Smith, has given ArtWatch UK full and most generously helpful access to all conservation and archival records, and that we have drawn heavily on the compendious material on the Gallery’s conservation practices that is provided in the annual Technical Bulletins. Moreover, since 2012 the Gallery has placed much archival material online.

Responses to “Art Restoration, the Culture, the Business and the Scandal”

After his initially even-handed coverage, Brian Appleyard now characterised Beck in the Independent as being “litigious” – even though he had brought no legal actions but had been sued (unsuccessfully) for criminal slander by an Italian sculpture restorer and had faced a possible prison sentence of three years. Appleyard compared the Beck/Daley book unfavourably before its publication – and before he had read it – with Walden’s book of 1985, specifically dismissing its unseen chapters on the Sistine ceiling on a Waldenesque insistence that “The fact that it was largely pure fresco made the cleaning process straightforward.”

On 18 November 1993 the New York Review of Books carried an essay by Charles Hope, on “Art Restoration ~ The Culture, the Business and the Scandal”. Hope (who was later to become, as Gombrich had been, the director of the Warburg Institute), recalled that “like many other art historians” his initial response to the cleaning had been “entirely favourable”, but which confidence, he now confessed, had been “entirely misplaced”. Viewed in their entirety, the cleaned frescoes create “a decidedly disagreeable impression: the colours are gaudy…the figures look crude and often flat and the architecture seems insubstantial and pedantic.” In short, “Restrained grandeur has been replaced by garish confusion” and it was “difficult to believe that the right procedure was adopted.” Worse followed for the restoration establishment. “Restorers are not always particularly well-informed about the history of art nor especially interested in it”, while, for their part, art historians “seldom have the scientific training to judge the full implication of the courses of action proposed to them.”

Perhaps most disturbing to the Sistine Chapel restoration supporters was Hope’s acknowledgement that when “Talking to friends I find that my unease is widely shared; and it is certainly noticeable that the completion of the restoration has not attracted the kind of acclaim that greeted the unveiling of the lunettes.” After the publication of his review, Hope told Beck in a letter (20 November 1993) “You’ll be cheered to know that several art historians have told me, by letter or in person, how glad they were that I had said what I did.” This greatly amplified a note of caution that had already been present in Nicholas Penny’s observations in the LRB nine months earlier:

I have met few art historians, even among those who are nervous about the cleaning of paintings, who believe that a mistake was made in cleaning the ceiling. Nevertheless, many art lovers were shaken by what has been published on the subject and some have been no less alarmed by what they have seen in the chapel itself.”

A Restorer’s Response

Temperatures rose after Hope’s review. The Art Newspaper allotted four pages in its May 1994 issue for the counter arguments of Helen Glanville, a Courtauld Institute-trained picture restorer who had read Modern Languages at Oxford. Like Brandt seven years earlier in Apollo, Glanville struck a combative tone and a tendentious note by producing accounts of our “Accusations” against which she provided lawyerish “Defences” written in consultation with the authorities. In 1963 Gombrich had complained “Nobody who criticizes the policy of a great institution expects such criticism to be accepted without further argument. What one has the right to expect, however, is that the answer should concern itself with the substance of the criticism.” In language eerily reminiscent of that used against Beck by Shearman, Glanville challenged not only our character but the judgement of those who had supported us: “The most disturbing aspect is that reviews of the book (including that by Charles Hope in the New York Review of Books of 18 November 1993) appear to indicate that even respected members of the art world accept Daley’s presentation of ‘facts’ at face value”.

Hope’s Riposte

Hope sent a letter to Glanville explaining that he had been “particularly careful not to take Daley at his word”, that he had checked what I had written on Sebastiano was in accordance with the monograph on the artist by Professor Michael Hirst (of the Courtauld Institute, and a member of the Vatican’s Pontifical Commission for the Restoration of the Sistine Chapel ceiling), and also with “the account of the [Sebastiano] restoration in the National Gallery’s Annual Report”. In further reproach, he added “I would have thought it was fairly obvious to anyone familiar with the recent literature that I had done my homework, not least because there are various arguments and texts used in the review which do not figure in the Beck-Daley book at all. [5] In my review I have tried very hard to be fair to both sides…Having read your article I see nothing that ought to be changed; indeed it would be difficult to see what you actually found objectionable in it…Before I began working on the review my scholarly sympathies were entirely on side of the defenders of the recent restoration, and I was hoping indeed expecting, to be persuaded that my unease at the present appearance of the ceiling was unjustified. But the reverse has happened, and not just because Beck and Daley produced such compelling arguments…” Hope then set out with great clarity the scholarly import of the material evidence we had supplied and which he had found persuasive:

I was disappointed that you did not discuss directly what seemed to me the most important single type of evidence in the whole controversy, the drawing by Clovio of Jonah [see Fig. 1] and the one at Windsor showing the whole ceiling. Both of these, as you will remember, can be securely dated to no later than 1534, and they both show very specific, well-defined areas of shadow also recorded in the engravings of the sixteenth century and later, which have now disappeared. The important thing is that the drawings predate the engravings, that they were manifestly produced independently of one another, yet they are consistent. If they are misleading in the same way, we need to have some explanation of why this is so, because if Michelangelo did paint shadows of the kind they show, and in the places they show, then Beck and Daley would seem to be vindicated.”

Gombrich’s Denial of Historical Realities

Coming so soon after Hope’s generous and substantial support, Gombrich’s claim, as a scholar with an impeccable record as a critic of restorations, that cast shadows had popped out of existence for the duration of the High Renaissance might have seemed like manna to the National Gallery and the Vatican. Did his historical account not implicitly constitute a most authoritative rebuttal of the Beck-Daley, Hope-supported, central claim that the destruction of Michelangelo’s cast shadows had given historically corroborated proof of injury to the Sistine Chapel ceiling? In so doing, did he not also provide express relief to the restorers themselves? If the shadows had never existed during the High Renaissance, as he was claiming, how could they possibly have been harmed in restoration?

In May 1994 The Art Newspaper published my letter of reply to Glanville’s article. It concluded: “this concern [over restorations] is shared by others. The current director of the Prado, Calvo Serrraller, has condemned the Sistine Chapel restoration as a misguided ‘face-lift’. A restorer in St Petersburg complains of the ‘perniciousness of radical British restoration techniques’. A curator of New York’s Metropolitan Museum condemns the ‘strident tones’ produced by ‘the exuberant cleaning of paint surfaces, for which the National Gallery has unfortunately become famous’. It is a pity that the National Gallery staff are not prepared to debate these matters directly. It is a pity that discussion should be necessary at all when, to educated eyes, the evidence of injury contained in before and after cleaning photographs is so unmissable.” It would seem, (on Gombrich’s recollection – “In the shadow of the masters”, interview, The Art Newspaper, May 1995) that that very month, the National Gallery’s director, Neil MacGregor, approached Gombrich to ask whether he would do an exhibition in the “The Artist’s Eye” series (in which artists assembled and discussed selections of paintings made from within the Gallery’s collection).

Mr MacGregor’s Choice

Gombrich submitted five or six proposals from which, he said, MacGregor “selected shadows”. Thus the National Gallery had obtained an exhibition that purported to explain why the masters of the High Renaissance had opted to “show us a shadowless world”. If the content was helpful to the Gallery, the fact of Gombrich’s participation might have been a greater boon still. As a critic of the Gallery’s restorations during the 1950s and 1960s he had been a dangerous foe. Before becoming the National Gallery’s director, MacGregor, as editor of the Burlington Magazine, had himself been a partisan of restorations and was well aware of Gombrich’s standing in these disputes. In a Burlington editorial in January 1985, MacGregor had written:

Cleaning controversies are probably the liveliest, and they are certainly the hardiest, of the art world’s perennial topics of discussion. Of course, thefts and exports make bigger headlines, but they lack conversational staying power, just as new record prices slip faster and faster from the memory. But debates on cleaning run and run, this Magazine having been the forum for one of the most celebrated jousts in the early 1960s.”

MacGregor then drew a distinction that marked a crucial advance that picture restorers had made by the 1980s: “Then the key question was how, or even whether, to clean. Now it is more likely to focus on what can be learnt through cleaning about the picture itself.” This rebranding of art restoration, despite all of its inherent risks, as an aid to scholarship had seemed a spectacular professional coup. By the late 1980s museum restorers had forged a common professional alliance with curators in which “discoveries” made in the course of a restoration could be presented to the world through professional journals, museum press releases, and newspaper/television interviews. The National Gallery laid claim for having pioneered the new hybrid discipline known as Technical Art History, in which curators, restorers and scientists pool efforts so as to fly in tight professional formations. In reality, museums and galleries had set themselves a trap – and Gombrich had chosen the worst possible moment to flip sides in the Great Restoration Battles: to talk about what has been learned/discovered requires the production of material, visual evidence and such evidence becomes fair game for examination.

Gombrich’s Case Against the National Gallery’s Restoration Methods

In 1950 Gombrich had drawn attention in a letter to the Burlington Magazine, to a passage in Pliny which described wondrous effects achieved by the legendary painter Apelles when he finished off his pictures with a thinly spread dark coating or “varnish”. How could we be sure, Gombrich asked, that no Renaissance masters had ever emulated the great painter of antiquity by applying similarly toned varnishes to their own works? He received no reply from the National Gallery. Ten years later, he put the question again in his book “Art and Illusion”, this time provoking Helmut Ruhemann, the Gallery’s pioneering exponent of “Total Cleaning”, into a categorical insistence that “there is no evidence for anything so inherently improbable as that a great old master should cover his whole picture with a ‘toning down layer.'”

Gombrich returned to the fray in 1962 in a Burlington Magazine article (“Dark varnishes – Variations on a Theme from Pliny”) contending that even a single instance of tinted overall varnish would undermine the philosophy of the Gallery’s intrusive restorers who presumed to discern and recover originally “intended” effects among the complex, variously degraded, many times altered material layers of old paintings. Gombrich had cited Pliny’s remarkable technically eloquent account of Apelles’ method: “He used to give his pictures when finished a dark coating so thinly spread that, by reflecting, it enhanced the brilliance of the colour while, at the same time, it afforded protection from dust and dirt and was not itself visible except at close quarters. One main purpose was to prevent the brilliance of the colours from offending the eye, since it gave the impression as if the beholder were seeing them through a window of talc, so that he gave from a distance an imperceptible touch of severity to excessively rich colours.” To the National Gallery the suggestion that colour might be suppressed in any degree by an artist was an affronting heresy, and the idea that a dark toning layer might simultaneously render colours individually more brilliant while collectively more unified was an oxymoron.

The Gallery’s then head of conservation science, Joyce Plesters, responded with a long, witheringly dismissive rebuttal in the Burlington (“Dark Varnishes – Some Further Comments”). Professor Gombrich, she insisted, lacked “technical knowledge” and his scholarship was incomplete and misinterpreted. The entire documented history technical history of art – much of which she appeared to quote – showed that “no convincing case” could be made for a single artist ever having emulated Apelles’ tinted varnish. The passage from Pliny, she sniffed, was but a matter of “academic rather than practical importance” – a charge that was echoed by the director, Philip Hendy, in the Gallery’s Annual Report where he disparaged technically ignorant “university art historians”. Plesters grandly offered to “sift” and “throw light” upon any further historical material that Gombrich or others might care to present in future directly to the National Gallery. Once again, a moment of high political danger for the Gallery’s restorers and curators passed: if no evidence existed of artists having used glazes and varnishes in the manner alleged by critics, how could restorers possibly be damaging them?

The controversy slowly subsided into isolated protests such as that of the painter Pietro Annigoni who painted “MURDERERS” onto the doors of the National Gallery, one night in 1970, in protest against what he had described in a 1956 letter to the Times as “atrocious results [that] reveal an incredible absence of sensibility”. But by 1977 it was “game-over”, so to speak. That year the National Gallery felt confident enough to launch its Technical Bulletin in which restoration methods would be described and illustrated. In it, Plesters mused complacently that “one or two readers may recall the furore when the cleaning of discoloured varnishes from paintings…began to find critics”. (On Plesters’ own technical incompetence, see our post of 27 January 2011.) In the same year a former director of the Gallery, Kenneth Clark, pronounced picture cleaning “a battle won” and claimed responsibility for the victory by having installed a “scientific department with all the latest apparatus” at the National Gallery. He had done so, he said, not because he believed in the “application of science to picture cleaning”, but rather because “until quite recently the cleaning of pictures used to arouse extraordinary public indignation, and it was therefore advisable to have in the background what purported to be scientific evidence to ‘prove’ that every precaution had been taken.”

Gombrich’s Vindication

Joyce Plesters died in October 1996. Earlier that year the National Gallery’s Technical Bulletin carried reports of the cleaning of two paintings by Leonardo’s follower Giampietrino. One, his Salome, had suffered the usual weakening of modelling and shading. The other, his Christ carrying his Cross (Fig. 45) had not. Intriguingly, the latter was said to enjoy both “intensity of colour” and a “restrained overall effect” – the very paradoxical effect the Gallery had dismissed as inherently improbable. Even more remarkably, Giampietrino had first built up an “illusion of relief” with “dark translucent glazes”, and then – just like Apelles – had deliberately “restricted his own range of values” with “a final extremely thin overall toning layer consisting of warm dark pigments and black [!] in a medium essentially of walnut oil with a little resin”. The “varnish” was thus virtually identical as a material to the painting itself – which may explain why it had survived for so long. Many, more soluble, resin varnishes with warm dark pigments had been judged to be earlier restorers’ attempt to impart a deceiving “old masters’ glow” after a harsh cleaning…and removed as alien disfigurements.

Conspicuously, the Technical Bulletin reports made no reference to the Burlington Magazine’s celebrated joust of the early 1960s. Had the Gallery privately informed its recently honoured guest exhibitor of his belated vindication, we wondered? It had not. When we informed Gombrich of this technical corroboration, he replied:

Many thanks for your letter. I happen to have a birthday these days (87, alas!) and I could hardly have a nicer present than the information you sent me. I don’t ever see the N. G. Technical Bulletin and would have missed their final conversion to an obvious truth! Better late, than never. There is more joy in heaven (or Briardale gardens)…”

We published an account of the National Gallery’s remarkable discovery, and of Gombrich’s response to it, in the November 1998 Art Review (“The Unvarnished Truth”). Three years later in a prefatory remark for the revised 2004 edition of Walden’s book “The Ravished Image”, Gombrich announced: “It is now clear that the position I took forty nine years ago in this matter has been vindicated”. As, indeed, it had been, but curiously, Gombrich declined to mention the fact that an exact analogue of Apelles’ reported practice had been discovered on the work of an associate of Leonardo’s within the conservation studios of the Gallery which had originally dismissed his claims but recently honoured him with an “autograph” exhibition. Instead, he attributed his vindication to research reported five years later in a Burlington Magazine article of January 2001 on work conducted in the conservation studios of the Getty Museum. The article, “‘Amber Varnish’ and Orazio Gentileschi’s ‘Lot and His Daughters'”, by Mark Leonard, Narayan Khandekar and Dawson W. Carr, was certainly an important document. It reported that underneath a thick recent, disfiguring but easily soluble varnish, an older thinner much tougher (but still soluble) varnish “remained directly on the paint surface in many areas.” Examinations of paint samples established that “in some areas at least”, this varnish layer had been applied “very early in the life of the painting”, if not originally.

It had been found that in areas where sections of this early, possibly original varnish had been removed in earlier cleanings, the artistic consequences had been devastating: “One particularly prominent loss was in the neck of the daughter at the left. The older varnish remained intact throughout the face, yet at the line of the chin it had been broken through, and removed throughout the rest of the neck. To the naked eye, it looked as if the final layer of modelling in the neck had been ripped from the surface. Although the preparatory flesh tones were still intact, the carefully nuanced sculptural solidity found throughout the rest of the face was missing.” Although no one noticed it, this last remark echoed and corroborated Annigoni’s Times complaint of 1956 that restorers at the National Gallery pronounce “miracles” when “brilliant colours begin to appear“. Unfortunately, he continued, “what they have found are nothing but the preparative tones, sometimes even of the first sketch, on which the artist has worked carefully, giving the best that is in him, in preparation for the execution of the finished work.”

Welcome as such recent confirmations of longstanding claims by artist and art historian critics of restorations are, it should be noted to how great an extent they are arising after the horse had bolted. The National Gallery has yet to disown any of its post-war restorations – in which period it has restored and often re-restored almost its entire collection and often to seriously deleterious effects (see Figs. 55 to 59b by way of example). As the unwisdom of stripping off old varnishes finally begins to gain acceptance in restoration and curatorial circles, the fact remains that had artists’ testimony been heeded, not only would the ponderous and hugely expensive particle accelerators and other “diagnostic” apparatuses of modern museum conservation departments not have been needed, but that much of our visual cultural patrimony could far sooner have been spared mistreatment. Even before Gombrich’s first 1950 letter to the Burlington, in 1946, a painter, Laura Knight, had explained the intrinsic dangers of picture cleaning with perfectly calm “hands-on” knowledge and clarity in a letter to the Times (27 November):

With the exception of direct painting, a comparatively modern method, a painter builds his pigment onto canvas or panel – always with the final effect in view. The actual surface of a picture is the picture as it leaves the artist’s hand. The varnish which finally covers the work for protection to a varying extent amalgamates with the paint underneath. Therefore drastic cleaning – the removal of the covering varnish – is bound to remove also this surface painting and should never be undertaken.”

Although Gombrich might well once again have been feeling that “There is more joy in heaven…” this early or original Getty Museum Varnish had not corroborated his Apelles’ thesis to the same degree as the National Gallery’s research on the Giampietrino. There, the surviving original “varnish” layer was not simply naturally discoloured but had been deliberately loaded with “warm dark pigments and black”.

Had Gombrich learned of his own vindication on this point a decade sooner, he might perhaps have been less censorious of those who claimed that Michelangelo, too, had toned down his own colours with black pigment on the Sistine Chapel ceiling. He might even have been less easily persuaded that Michelangelo had confined himself to painting into wet plaster with waterbound pigments. For that matter, even as late as 1993, had Gombrich heeded (as had done his successor at the Warburg Institute, Charles Hope), the hard evidence we presented in “Art Restoration” that the most massively extensive applications of original dark toning layers had occurred on the greatest masterpiece of the High Renaissance – Michelangelo’s Sistine Chapel ceiling – he might have enjoyed his sense of vindication sooner [6]. He might also then have appreciated that the very technical proof of the antiquity of the discoloured layer on the Orazio Gentileschi painting (the fact that this layer had not run into pre-existing age cracks) had been observed more than a century earlier on the surface of Michelangelo’s Sistine ceiling; that the ceiling’s controversially removed a secco passages had, in fact, precisely passed the Getty Cracks Test. As Charles Heath Wilson had discovered and reported when examining the ceiling within touching distance: “There can be no doubt that nearly all of this work is contemporary, and in one part only was there evidence of a later and incapable hand. The size colour has cracked as the plaster has cracked, but apart from this appearance of age, the retouchings have all the characteristics of original work.” Where Brandt had reported in her influential Apollo article that while the restorers had been on the lookout for “the famous secchi”… “they were surprised not find a secco passages”, Wilson had found it without any difficulty (and without any hi-tech apparatus) because: “Retouches in size-colour are easily recognised. Pure fresco has a metallic lustre, but the retouches are opaque. They are also necessarily painted differently from the fresco, have a sketchy appearance, with hard edges, or are hatched [see Fig. 34] where an attempt is made to graduate them.”

Perhaps, even after twenty further years of campaigning, we might need to re-emphasize that earlier testimony of Wilson’s: the size colour had cracked as the plaster had cracked. The glue/size had not run into any pre-existing cracks. That is to say, the size colour had been applied before the plaster had cracked. The plaster is known to have cracked before any restorers went near the ceiling. Ergo, the size colour could only have been applied when the ceiling was new – and therefore Michelangelo alone could have been the author of the secco painting that lay so clearly to view on the dry surface of his frescoes. This hard technical proof cross-links with the even earlier artistic corroboration of Michelangelo’s authorship of the shading and the cast shadows that was found in Clovio’s beautiful hand-drawn sketch of the Jonah shown at Fig. 1. Moreover, had Gombrich heeded our 1993 account, he would also have appreciated that Wilson had, a century earlier, precisely confirmed his Apelles’ dark toning thesis, insofar as Michelangelo’s extensive secco paintwork had been observed to have “consisted of a finely ground black, mixed with a size”.

By accepting Wilson’s firsthand testimony, Gombrich would further have appreciated, pace Mrs Walden, that Michelangelo had put this secco work to the following extensive artistic ends:

The shadows of the draperies have been boldly and solidly retouched with this size colour, as well as the shadows on the backgrounds. This is the case not only in the groups of the Prophets and Sibyls, but also in the ancestors of Christ in the lunettes and the ornamental portions are retouched in the same way. The hair of the heads and the beards of many of the figures are finished in size colour, whilst the shadows are also thus strengthened, other parts are glazed with the same material, and even portions of the fresco are passed over with the size, without any admixture of colour, precisely as the force of watercolour drawings is increased with washes of gum…These retouchings, as usual with all the masters of the art at the time, constituted the finishing process or as Condivi expresses it, alluding to it in the history of these frescoes, ‘l’ultima mano’. They were evidently all done at the same time and therefore when the scaffold was in place.” And not only! He would have seen an anticipation of the Getty Museum Optical Identification of Aesthetic Injuries Method. That is, Wilson had testified precisely that the faces of the Prophets Daniel and Jeremiah had “undoubtedly been injured by rude hands, suggesting that glazing has been partially or entirely swept away”. Specifically: “The face of Jeremiah seems colourless and painted in black and white only: that the face of Daniel is blotched with brown marks.”

Gombrich had thus been magnificently vindicated twice over on his Apelles Thesis: once on the testimony of a close follower of Leonardo, and once on the testimony of the mighty Michelangelo. He had very graciously accepted news from us of the (lesser) confirmation from within the National Gallery. How sad it is that he had left himself unable to lay rightful claim to the vastly more substantial example of Michelangelo’s Sistine Chapel ceiling paintings. How sad, too, that in defending his error of judgement on Michelangelo, he should have obliged himself to unperson the artistic legacy of the twin giants Michelangelo and Raphael in order to mount an incoherent untenable shabby little exhibition at the National Gallery.

CODA:

Sad as this all is, even now, it is not yet the end of the tragedy. Art historians and their (reversible) tribulations aside, how terrifying it remains that the consequence of the destruction of the precious historic/artistic material that comprised the finishing stages of Michelangelo’s own paintings (and which had protected the fresco surfaces for hundreds of years) is that the remaining now stripped-bare surfaces have been left prey to a persisting polluted atmospheric stew for which no solution has been found by the Vatican’s technical and scientific wizards after two decades of assurances – and twenty-six years after Prof. Brandt disclosed in Apollo that “I have urged repeatedly that problems of climate and pollution control in the Sistine Chapel be given higher priority.” In our post of 21 January, “Setting the Scene, Packing Them In” we cited reports that as many as 20,000 visitors a day were being run through the Chapel. Already, we are outdated. More recent reports put the daily total as high as 30,000 – and report a new pestilence: pickpockets operating within the Pope’s private chapel.

The force of this distinction masked certain inconsistencies. For example, even in Britain during the early post-war period when national schools or tendencies were most pronounced, two highly successful German restorers represented polar opposites in picture restoration’s “ideological” wars. While Helmut Ruhemann lead the controversial school of “Total Cleaning” from within the National Gallery, Johannes Hell championed the philosophy of gradualist and minimalist restorations in which an overall appraisal of the aesthetic consequences of cleaning was maintained at all times. Hell, whose work was admired by members of the Royal Academy, including its painter-president, Gerald Kelly, did so from a successful career within the private sector but his disciples were to gain influential positions in the US museum world. Today, the linkage of competing restoration philosophies to national practices has lost almost all force. All museums – like the Louvre, like the Getty – now sport increasingly powerful science departments and engage nationally and internationally in the kind of professional collaborations between restorers, scientists and curators that operate under the new umbrella discipline know as Technical Art History – and there is scarcely a Technical Art Historian today who would subscribe to a “Total Cleaning” philosophy. Virtually to a person, restorers nowadays declare themselves to be minimalists. 4.

He warned how misunderstandings of key art historical terms such as sfumato and colorito had carried grave and irreversible consequences for much art “as it did in the case of the Sistine ceiling”.

I then wrote a piece for Harvard Magazine on the subject, which Jim Beck told me helped persuade him to join us.

Above, Fig. 1a: A copy of Michelangelo’s Prophet Jonah. This wash drawing by Giulio Clovio and owned by Rugby School of Art, England, is the single most compelling and illuminating indication of the nature of the restoration injuries to Michelangelo’s Sistine ceiling.
It records in its bottom corners parts of two lunettes that Michelangelo had painted before 1512 but then destroyed by 1534 when preparing the altar wall for his Last Judgement. It is therefore a record of how Michelangelo’s painting appeared before the frescoes had become dirty and before any restorer had approached the ceiling. Crucially, and like so many subsequent copies, it shows that Michelangelo had painted with dramatic lighting effects which modelled his figures strongly in relief and caused them to cast shadows onto surrounding surfaces. Moreover, this pronounced Light/Dark pictorial system is seen to have been applied consistently to all figures, including the decorative sculpted children who adorned the architecture or performed subsidiary tasks such as supporting name plates. The cast shadow here seen attached to Jonah’s left foot was thus present from the very beginning. It could not have been an accumulation of soot from candles or braziers, or a later restorer’s addition, or an optical illusion created by darkening restorers’ “varnishes”, as have variously and collectively been suggested. (In truth, there is no record of any restorer applying any varnishes across the ceiling.) This was Michelangelo’s own entirely autograph cast shadow and it was included in every copy of the Jonah (see Fig. 1b below). It had survived for over four and a half centuries but was removed during the last restoration – as seen in Fig. 1c below.
There can be no grounds for disregarding Clovio’s testimony – and as Charles Hope noted (below left), none had been offered by supporters of the restoration. If Michelangelo had not constructed his figures and spaces in the manner recorded, how or why would Clovio have imposed those values? Vasari described Clovio as “the Michelangelo of small works” who had “far surpassed all others in this exercise.” This drawing’s recorded values are entirely consistent with all contemporary accounts of the ceiling when it was unveiled and there are no grounds for rejecting this testimony. Because the restored ceiling was no longer consistent with this (and other copies) or with the contemporary records, the restorers called for – were indeed obliged to call for – a new history to be written to accomodate the (spurious) “New Michelangelo” for whom they wished to claim credit.
Above, Fig. 1b: copies of Jonah, left, by Rados, engraving, 1805-10; right, drawing by Conca, 1823-29. Below, Fig. 1c: Michelangelo’s Jonah, before cleaning (left), and after cleaning (right).
Above, Figs. 2 and 3: The right foot of Michelangelo’s Erythraean Sibyl on the Sistine Chapel ceiling, as found after cleaning and retouching. We assume that no one would claim that Michelangelo intended the foot to be seen in its present condition, or dispute that these two photographs record a grossly injured passage of painting. The present double image is the bodged outcome of the wrongful removal (by accident or following a misdiagnosis of the surface painting) of a revised foot that Michelangelo had superimposed over an originally positioned foot. That now-destroyed later foot was copied in countless graphic works.
Above, Fig. 4: The Libyan Sibyl’s left foot, sans cast shadow, after “cleaning”. As with Figs. 2 and 3, we had thought when publishing this image in the 1993 book “Art Restoration, the Culture, the Business and the Scandal”, that support for this outcome would not be forthcoming. We were wrong. The restorer Helen Glanville, writing in The Art Newspaper (see below), offered the following defence: “after cleaning, Michelangelo’s alteration in the outline of the Libyan Sibyl’s foot can be seen more clearly”. This was written, presumably, in the belief that Michelangelo had intended to depict a heel not rounded but that came to a point? For an indication of the horrendous injuries and tonal losses inflicted on this foot – and the rest of the figure – see Fig. 60.
Above, Fig. 5: A detail of the mother in Michelangelo’s Ezechias/Manasses/Amon lunette. When this photograph was published in 1986, the co-director of the restoration, (the late) Dr Fabrizio Mancinelli said of the painting method on the lunettes:
Technically speaking, the lunettes are all executed in buon fresco…with nothing done a secco and without even those retouchings which were normal to harmonize the painting when the intonaco had dried too quickly or when one giornata differed excessively from those of the previous day. Michelangelo made sure to use only those colours that he knew were suitable to fresco: …the greens are ferrous silicates…Further, where there are corrections, the colours of the colouring-over are water-soluble and have mixed into the plaster.”
When we drew attention to the incompatibility of that account with the injury seen in the photograph above, where both greens and yellows that had been painted over underlying flesh and costume perished (letter, Michael Daley to Kathleen Weil-Garris Brandt, 27 May 1990), the account was changed and it was acknowledged that “a green colour applied a secco, not always well conserved, was found”.
Above, Fig. 6: A detail from Michelangelo’s The Punishment of Haman containing, in its centre wedge-shaped section, a repair made made by the painter Domenico Carnevale in 1566 or shortly after.
No technical proof of a restoration-injury could be clearer than Carnevale’s repair here to the lost section of Michelangelo’s painting that ran through the centre of the figure above. Carnevale had replaced the plaster and while it was still wet, painted it to match Michelangelo’s adjoining colours and tones. Carnevale’s paintwork ceased to match Michelangelo’s painting when his finishing glue/size additions were removed (with AB 57 and copious washing) during the restoration. It is artistically inconceivable that Michelangelo had painted flatly and without sculptural/tonal modulations, as today seen today in the outer flanking sections of painting. Even if he had he done so, it would then be no less inconceivable that Carnevale would have repainted the lost central section with lashings of black shading that did not match Michelangelo’s then surviving painting.
On Carnevale’s highly skilfully matched repairs to Michelangelo’s painting elsewhere on the ceiling, see Alessandro Conti’s comments at Fig. 48a and 48b.
How Michelangelo’s Ceiling was Undone:
Above, Fig. 7: National Geographic’s beautifully balanced record of December 1989 (here flipped) by Victor R. Boswell, Jr., showing (in the bottom section, below the restorers’ scaffold) the last moments of the Sistine Chapel ceiling as it had been finished by Michelangelo and as it met the top of the Last Judgement. Note how closely linked were the the generally dark tonalities of the ceiling and the Last Judgement and how in both, the figures advanced towards the viewer from within the prevailing darknesses – the very effects which had been reported by Michelangelo’s contemporaries and recorded in copies made from the earliest days of the ceiling. Note, too, how in the central figure of Jonah, the shadow cast by his left foot could still be seen clearly, even at this considerable optical distance – after four and a half centuries and through whatever degree of dirt was then present. As recalled left, the Sunday Times’ art critic, Waldemar Januszczak, likened the cleaning changes to seeing Beethoven turning into Mozart during “a memorable piece of theatre.” Januszczak was even more (debunkingly) delighted with the final result:
The windshield wiper has finished its journey across the greatest painting in Western art. In my opinion it has made that painting substantially greater by celebrating it as the work of of a rational, hardworking, colourful human rather than some sweaty impulsive, God-driven genius.”
Above, Fig. 8: The chapel, as seen when all parts had been cleaned. A comparison of this photograph with that at Fig. 7, shows that the former unity of tones between the Last Judgement and the adjacent ceiling has been ruptured. The darks that had been common to both were vital to the creation of spatial depth and atmosphere. In the not-yet-cleaned section of the ceiling in Fig. 7, it is striking how the architectural elements had seemed brighter, even when their surfaces had not been cleaned. This is because, in art, all values are relative and a given, actual tone can be made lighter or darker simply by altering the values of its neighbouring tones. In the ceiling before cleaning, we see how Michelangelo created pools of darkness in the corners of the intersecting architectural borders so as to evoke recesses from which his figures emerged. After “cleaning”, the previously strong drapery colours are no longer subsumed within overall tonal schemes but float about, catching the eye arbitrarily. This new configuration of effects was deftly described by Charles Hope (see left) as as one in which:
Restrained grandeur has been replaced by garish confusion.”
That grandeur and restraint had been hard earned over four years of punishing painting. The uncleaned section of ceiling shown above at Fig.7 was the last part to be painted. It contained Michelangelo’s greatest figural inventions and his most considered and successful orchestrations. It constituted a stupendous finale that for a generation awaited his Last Judgement. Separating the one from the other with chemically-induced tonal and chromatic variations was a dreadful lapse of judgement.
How the Injured Ceiling Came to Britain:
Above, Fig. 9: The cover of the Sunday Times colour magazine of 20 December 1987 carrying a composite juxtaposition of photographs showing the head seen below at Fig. 10, when partly cleaned, partly uncleaned. (There has been some fading on the right-hand edge of this copy of the magazine, but the indication of the relative values of the two states is a fair one.)
Above, Fig. 10: The head of Michelangelo’s ignudo situated above the top left-hand corner of the ceiling panel depicting the Sacrifice of Noah, details of which are shown below at Figs. 48a and 48b, as discussed by Alessandro Conti. Note how in this large plate of 1965, the colours are strong and the modelling is stronger. Note the then survival of the pupil in the man’s left eye. Note the then strength of the locks of hair behind the brow, and the sharpness of the drawing at the nostrils.
Above, Figs. 11a and 11b: The comparison here of a detail of Michelangelo’s ceiling before and after cleaning was published in the Sunday Times magazine on 20 December 1987. It instantly convinced this author that the “cleaning” was damaging on the following grounds: if the after-cleaning state (as shown above right) had truly recovered the original appearance as left by Michelangelo in 1512, there could be no plausible explanation of how the painting might then have progressed towards the greater degrees of finish, modelling and sharpness that were seen (left) to have existed underneath the dirt immediately before the “cleaning”. The official suggestions that the superior passages of modelling seen before cleaning were fortuitous by-products of accumulations of soot from braziers and candles and from discoloured restorers’ “varnishes” were technically preposterous. The reinforcement of drapery folds with dark shadows (as seen left) is too closely related to the designs to have been accidental. Similarly, no accidental and arbitrary proccesses could have sharpened the drawing of the oak leaves and, even, added veins to the leaves. To any artistically-trained eye, it is self-evident that the post-cleaning state shown here records an abraded version of the original values that had survived underneath all grime until the time of the last restoration. Moreover, had a disfiguring film been safely removed from an underlying image, the values and relationships that were previously visible in that image underneath the film would have emerged with greatly increased, not diminished, force. The lights would have appeared lighter and the darks darker. Here, more was visible underneath the dirty surface than remained after the cleaning. The difference between the two enables the viewer to callibrate the extent of injury that occurred during the cleaning.

Above, Fig. 14: The mother in Michelangelo’s Ezechias/Manasses/Amon lunette, as seen before restoration (left) and after (right). If the detail examined in Figs. 11a and 11b posed problems for supporters of the restoration, this comparison of one of the giant figure groups is crushingly impossible to explain away. Once again, it must be asked: if the cleaned state on the right had constituted a recovery of original painting, by what means had so many tonal values and relations been altered or, even, inverted so that light-on-dark became dark-on-light? By the same token, why did relationships that were previously evident underneath the grime change character and emerge with diminished, not enhanced, pictorial vivacity?
Conflicted Accounts: Shadows V. Non-Shadows
Above, Figs. 15 and 16: Left, the 1993 first edition (publisher: John Murray, London) of “Art Restoration”, showing the Prophet Jonah before cleaning – and, therefore, when still retaining the left foot’s cast shadow, as first recorded before 1534 by Giulio Clovio and as seen here at Fig. 1. Right, the book/catalogue (publisher, National Gallery Publications) for Sir Ernst Gombrich’s 1995 National Gallery exhibition on the depiction of cast shadows in Western art, showing a detail of a painting by a follower of Rembrandt. Gombrich warned his reader/viewers that the book/exhibition would not “offer a coherent history of cast shadows in art”. He was as good as his word: claiming that cast shadows had not been employed by Renaissance artists, he failed to discuss the work of either Michelangelo or Raphael, suggesting by implication that neither had employed cast shadows – when, as will be seen, nothing could have been further from the truth.
Above, Fig. 17: A preview of “Art Restoration” by Martin Gayford in the Daily Telegraph that carried (left) a reproduction of Masaccio’s Saint Peter’s shadow healing a cripple in the fresco cycle at the Brancacci Chapel in Florence. One of the most striking features of Masaccio’s short life is that his Brancacci Chapel paintings came to be, as James Beck put it in “Art Restoration”, “copied and studied by the finest masters of the time, headed by Michelangelo, and were thought of as an unofficial school for artists”.
Sir Ernst Gombrich’s Bizarre Historical Disjunction
Above, Fig. 18: The St. Peter incident was a landmark in Gombrich’s Story of Shadows but only insofar as the event “could hardly have been rendered in the idiom of Masaccio’s predecessors”. For Gombrich, this was a great pictorial advance that began and ended immediately with Masaccio, after whom painting became a cast shadows-free zone until the “taboo was lifted in the seventeenth century” by the “pivotal” intervention of Caravaggio. This thesis was perverse and demonstrably untrue. The reason offered for this alleged shadows-free interegnum – specifically for “why so many artists of the Cinquecento withheld their attention from cast shadows” – is said in mystifyingly circular fashion somehow to have been explained by the fact that “There is hardly a function of cast shadows that is not illustrated by Caravaggio’s dramatic painting [ The Supper at Emmaus, here shown at Fig. 27].
Above, Fig. 19: Raphael’s The healing of the lame man. A detail of the St Peter and St John from the Raphael Cartoons in the Victoria and Albert Museum. It must be considered inconceivable that Gombrich was unaware of this image or likely to have been surprised by its echo of Masaccio’s treatment. So why did he neglect Raphael, whose cartoons for the fabled tapestries of the lower walls of the Sistine Chapel constitute one the greatest cycles of the Renaissance? We know that these cartoons were made in full consciousness of Michelangelo’s recently unveiled cast shadows-full Sistine Chapel ceiling, the force of which had so swamped and excited the younger artist that he was said instantly to have put aside all things Perugino. Why, then, drop both of these great masters from an account of cast shadows?
This particular image is potent in many artistic and art historical respects. Where Fabrizio Mancinelli claimed that colour had had for Michelangelo “a primary structural role”; that it had enabled him to “abandon almost altogether traditional chiaroscuro modelling”, we see that Raphael had clearly drawn a very different conclusion. Already, from his Ansidei Madonna of 1505, shown below at Figs. 22 and 23, we know that Raphael enjoyed a perfect grasp of the principles of tonal manipulation to sculptural and spatial ends. We can see here above that he took from Michelangelo the realisation that chiaroscuro was susceptible to immensely monumental and dramatically expressive pictorial purposes; that chiaroscuro itself can be used for a primary structural purpose within picture-making; that its lights and shades could be used not just to describe forms within a figure but to leap about figural groups, accentuating and/or uniting potentially disparate elements within a work’s overarching design; becoming, in short, a pictorially enriching compositional tool as well as a plastically descriptive one.
Leonardo’s Literary Testimony:
Above, Fig. 20: In his depiction of Christ’s charge to St. Peter, Raphael shows the saint’s shadow falling across Christ’s feet and neatly eclipsing the light on the toes of his left foot. This could hardly have been a little-considered feature of so monumental a work.
Against such artistic realities, Gombrich held that Leonardo’s writings provided “impeccable literary testimony” for his contention that Cinquecento artists had eschewed cast shadows. He asserted: “We soon realise that some of the greatest observers of nature appear to have deliberately avoided the cast shadow…they show us a shadowless world” (emphasis added). He then elaborated (without examples): “It looks indeed as if many of these masters had studiously avoided inserting such shadows, as if they regarded them as a disturbing and distracting element in an otherwise coherent and harmonious composition.” (Emphasis added.)
As if? But where is the beef? Gombrich took it to lie in this short passage in Leonardo’s Notes (Trattato della Pittura):
Light too conspicuously cut off by shadows is exceedingly disapproved of by painters. Hence, to avoid such awkwardness when you depict bodies in open country, do not make your figures appear illuminated by the sun, but contrive a certain amount of mist or of transparent cloud to be placed between the object and the sun and thus – since the object is not harshly illuminated by the sun – the outlines of the shadows will not clash with the outlines of the lights.”
And yet we see above that Raphael designed and composed with harsh lights and shadows in open country to be transposed (as below) into fabulously expensive tapestries to be shown on special occasions underneath Michelangelo’s frescoes.
Above, Fig. 21: Above, a detail from the Vatican’s tapestry The conversion of Saul as designed by Raphael and woven by astonishingly talented Flemish weavers. Saul is brilliantly lit by the Light of God and stumbles at its revelatory power. He, the fleeing Christians, and their persecuting soldiers, all have stark shadows cast by God’s radiant light.
Above, Figs. 22 and 23: Details of the National Gallery’s Raphael Ansidei Madonna. Had Gombrich not banished Renaissance cast shadows, he might well have included this picture from the Gallery’s collection in his own exhibition. It comprises a veritable showcase of cast shadow types (- and it did so nearly a hundred years before Caravaggio’s Supper at Emmaus, shown at Fig. 27). As seen in this pre-1938 photograph, there are simple shadows cast by rectilinear blocks; shadows cast by bare feet (which are always tricky things to depict); and, a tour de force demonstration of a cast shadow projected onto the shaded concave surface on the Virgin’s throne that might be taken to constitute a textbook demonstration of Alberti’s instruction that planes should “take their variations from the changing of place and of light”.
Above, Fig. 24: This detail is intriguing. Having to draw lots of fluted barley twist columns is a nightmare in any draughtsman’s book, but Raphael went further, insinuating panels of complex sculptural decoration. Where Michelangelo had confined his putti to flat surfaces (as behind the two Prophets below) Raphael affixes his to doubly curving surfaces. Moreover, many of the carved details of relief are (improbably) shown as if carved in the round, so as to cast their own tiny shadows – as with the vine stems, for example. Might this little self-inflicted labour have been thought by Raphael to constitute a “Protogenes’ Riposte” to the Apelles of his time?
Gombrich’s Great Raphael Joke
Above, Fig 25: Gombrich ran this photo-comparison of Michelangelo’s Prophets Ezekiel and Jeremiah in his 1987 (republished) essay “The Rhetoric of Attribution ~ a cautionary tale”, where, as discussed opposite, he attributed the Ezekiel – cast shadows and all – to Raphael, while under the influence of Leonardo.
Giampietrino’s Neglected Testimony, Part I
Above, Fig. 26: A detail of Giampietrino’s full-size copy of Leonardo’s Last Supper. As we will see, Giampietrino is an artist who appears to have been cast into some outer art historical darkness. Where Gombrich adduced evidence from the National Gallery’s Caravaggio The Supper at Emmaus of 1601 (as shown below) – and in Leonardo’s “impeccable literary testimony” – for why Cinquecento artists had eschewed cast shadows, we find contrary material testimony in this Giampietrino copy, that Leonardo himself, in his Last Supper of 1492-7/8, had been casting solid shadows from his bread, and translucent ones from his glass vessels, when he should have been doing no such thing having outlawed it in his own words while being trapped historically inside Gombrich’s shadowless interregnum.
Gombrich’s Game-Changer
Above, Fig. 27: The National Gallery’s Caravaggio The Supper at Emmaus may be in better condition than Leonardo’s too-often, too-radically restored Last Supper, and than Michelangelo’s recently restored Sistine ceiling, but there can be no grounds for accrediting him with a single-handled revival of strongly cast shadows, for the first time since Masaccio and Robert Campin, for the good reason that cast shadows had never gone away. Gombrich sees Caravaggio’s cast shadows on the tablecloth as “harsh” and therefore likely to have offended the traditionalists who had preceded him on the grounds that had they known of them they would have judged them to “interfere with the clarity of the composition”. Caravaggio, in Gombrich’s hands thus becomes a kind of “Doctor Who” time traveller, capable of inhibiting those who preceded him by means of his pending example. At the same time, just as soon as he came into artistic existence and influence, “many artists of the seventeenth century were rapidly converted to Caravaggio’s idiom, and the tenebroso (dark) style conquered not only parts of Italy but also whole regions of the north where it culminated in the art of Rembrandt.”
Gombrich seems (on many grounds) not have been familiar with Charles Heath Wilson’s 1881 “Life and Works of Michelanglo Buonarroti”. In that book, when discussing Michelangelo’s use of cast shadows on the ceiling, Wilson wrote: “the shadows cast by the figures which sit in front of the white marble arch, with its piers cornice and moulding, are painted with Rembrandt-like vigour, and must at one time have given those figures complete relief against the bright and fair resemblance of marble, now so dingy and so unlike what it has been.” For these figure/architecture relationships see Figs. 1, 25 and 60.
Graphic Recollections of a Shadowy World
Above, Fig. 28: A detail of Giorgio Ghisi’s early 1570s copy of Michelangelo’s Erythraean Sibyl. This engraving establishes that the configuration of tonal relationships around and behind the Sibyl’s head were present within sixty years of the ceiling being unveiled. As seen in the not-recently-restored state of the fresco below, that essential set of relationships had survived for approaching five centuries, and therefore could not have been, as the restorers’ have claimed, a product of arbitrary accretions and disfigurations.
Above, Fig. 29: Consider the content of this pre-cleaned scene of Michelangelo’s. The Sibyl is engrossed in reading a Great Book. Behind the book are two putti. One is lighting a lamp, an activity which may have disturbed the second, who rubs his eyes as if awaking from slumber. The sleepy child is set in deep shadow/darkness. That surrounding gloom throws into relief the Sibyl’s brightly lit head, from which a dramatic shadow is cast on the wall behind. Why then, are these The Shadows That May Not Speak Their Name in Gombrich’s book? Why can art historians and critics no longer see and celebrate the brilliantly inventive and expressive purpose to which they had been put by Michelangelo? Would it really be fanciful heresy to suggest that Michelangelo might have been using lighting effects to expressive ends ahead of Rembrandt? Or, that he was using using light and darkness metaphorically for a portrayal of Spiritual Enlightenment? What purpose is served by truncating Michelangelo’s achievements?
Above, Fig. 30: The contrast between the state above, before the last restoration, and that found here, is astounding. The removal of the shaded zone behind the Sibyl has left the sleepy putto dark-skinned against a light, scrubbed-down wall – yet another inversion of artistic values, and not an enhancement of the previously existing values. Reading the three images above in sequence, we see a progressive diminuition of tonal strengths and variations. This phenomenon of the “stone-washed jeans syndrome” is virtually a given in pictures that fall too frequently under the swabs of restorers. It should be acknowledged that there is evidence of injuries before the last cleaning: in the 19th century, the painter Charles Heath Wilson complained of secco work on the ceiling having been destroyed in places after being “washed by labouring men with water in which a caustic has been mixed”. But the downwards optical jump of values is greater between the pre and post-cleaning photographs of the last restoration, when the scientists-backed “labouring men” of our times decided that none of the secco was Michelangelo’s and removed it all with watery gels containing two “caustics”, one of which brightened the colours, while the other dulled them.
A Restorer in Denial
Above, Figs. 31 and 32: The Erythraean Sibyl’s head before cleaning (top) and after cleaning (above). When we published the above comparison in 1993 (in “Art Restoration”), we came under fire in an Art Newspaper review of April 1994: “Vandals or saviours. Are scientists helping to destroy the world’s art? Helen Glanville, a restorer with an historical perspective, challenges the latest accusation made against her profession”.
Above, Fig. 33: As seen above, Glanville, complained of a caption that had read “…before cleaning, and afterwards with shading lost” and suggested an alternative reading: “the discoloured glue layers masked the high finish and subtlety of Michelangelo’s modelling, emphasising deepest shadow and highlighting and obliterating the delicate transition tones.” The suggestion was without merit: discoloured layers do not simultaneously brighten lights and darken darks in a fashion that enhances sculptural legibility. To the contrary, we repeat, they compress ranges of values and they reduce tonal vivacity.
If we look more closely into the two states of the head, as seen in the three pairs of comparative details below, we find specific differences that cannot possibly be explained away on a discoloured varnish hypothesis.
Above, Figs 34 (top) and 35: Discoloured varnish (superimposed on the after cleaning state) could not have shaded the corner of the mouth with dark hatched lines so as to cause it tuck into the forms of the face. Nor could it have redrawn the apperture of the nostril so as to enlarge it. Nor could it have arranged itself into hatched vertical lines so as to shade the slumbering putto to the right and throw the lit profile of the Sibyl’s face into relief.
Above, Figs. 36 (left) and 37: Discoloured varnish could not have improved the internal modelling encountered in the ear. It could not have drawn a sharp line around the ear lobe. One could go on because there is scarcely a detail that had not been embellished and clarified by Michelangelo. There is below yet another category of changes that Glanville overlooked.
Above, Figs. 38 (left) and 39: Michelangelo had changed the design of the head with his secco revisions. The plaited “pony tail” had been greatly enlarged and strengthened; the back of the neck had been extended and shaded so as to throw it into relief against the lighter architectural zone. Such changes are only ever products of artistic intent and purpose. They should never be mistaken for dirt and removed.
The Testimony of Brilliant Lighting Effects within the Graphic Tradition:
Above, Fig. 40: In his account of cast shadows, Gombrich joins the stream of graphic depictions in 1604 with a British Museum image (by Saenredam after Cornelis Cornelisz) that illustrates the fable of The Cave of Plato. (It is a philosophically interesting example, for sure, but it leapfrogs by half a century the brilliantly lit compendium of cast shadows set within Plato’s “academy” as shown below.) Had Gombrich begun with Georgio Ghisi’s suite of six engravings made in the early 1570s after Michelangelo’s Prophets and Sibyls (including that of the Erythraean Sibyl shown above in detail at Fig. 28) the thesis of his National Gallery “Shadows” exhibition would have collapsed under the weight of its own implausibility. Every one of Ghisi’s engravings (made when the ceiling was only sixty years old) records strongly cast shadows that had survived well – if not intact – on the ceiling until the last restoration, as can be seen in Fig. 29.
Gombrich’s Neglected Graphic Testimony:
Above, Fig. 41: Enea Vico’s engraving of 1550 showing the studio or “academy” of Michelanglo’s rival Baccio Bandinelli. The testimony of such engraved records, like that of Giampietrino’s paintings, has been too little heeded in general terms, and was quite disastrously disregarded in the restoration of Michelangelo’s Sistine Chapel ceiling painting.
This copy is owned by the Metropolitan Museum, New York, which comments that Bandinelli had commissioned the engraving specifically to:
celebrate his achievements and pretensions as a teacher and man of learning. Vico conceived the artist’s workshop not as it must have looked but rather as a gentlemanly room peopled with industrious assistants in fashionable dress. Bandinelli himself appears at the extreme right in a garment adorned with a badge of knighthood, a sign of the rank he had recently received from Charles V. By equipping the studio with books and antiquities, Vico presents the making of art as an intellectual enterprise, and by naming the studio an “academy,” he associates it with Plato’s famous school. The foreground is strewn with classical statuary and human bones appropriate for anatomical study. Brilliant lamplight and flickering firelight cast evocative shadows and illuminate the figures bent over their work. Some of their poses and groupings are reminiscent of Raphael’s famous fresco The School of Athens, an analogy that further exalts the character of Bandinelli’s enterprise.”
A Second Stream of Testimony
The comments are fair and the reference to the depicted uses of brilliant light, highlights a widespread failure to recognise the remarkably dramatic lighting effects made by Michelangelo for all to see on the Sistine ceiling – and their great influence on his contemporaries. On the testimony of Vico’s engraved output alone, as seen above and below, the lie is given to the “shadowless world” advanced by Gombrich in his 1995 National Gallery exhibition. It is particularly to be regretted that such streams of artistic testimony are disregarded when they can have such direct bearing on the “conservation” of works of art. For one thing, their testimony is peculiarly reliable, owing to the fact that their unvarnished existences do not invite the adulterations of restorers.
Above, Fig. 42: If art historians can see connections between Michelangelo’s colours and those of the later Mannerists, why do they miss the connections between his systems of light and shadow and the brilliant working of that legacy in Mannerist print-makers? In Vico’s Mars and Venus a light every bit as brilliant as that seen in Gombrich’s choice above, at Fig. 40, is present. And, as for shadows, almost every last detail in the foreground (slippers, doves, cat, dog) sports its own cast shadow.
Above, Fig. 43: Gombrich’s second graphic example is a marvellously lucid and elegant image, but, again, it is one that helps moves his narration even further away from the Renaissance to 1684, when it appeared as an illustration within Roger de Piles’ “Elémens de la Peinture Pratique.” That particular graphic example had the virtue of linking to some nice definitions from Filippo Baldinucci’s “Vocabulario Toscano dell’Arte Designo” of 1681: “Shadow: The Darkness created by opaque bodies on the opposite side of the illuminated part”…”Shadow: In the language of painters it is generally understood to refer to more or less dark colour which serves in painting to give relief by gradually becoming lighter”…”Cast Shadow (sbattimento) is the shadow that is caused on the ground or elsewhere by the depicted object…” Again, this further throws the reader off the scent of the High Renaissance and its actual practices of depiction and its associated uses of cast shadows.
Michelangelo, of course, could not have known de Piles but he could hardly not have known Alberti’s “Della pittura” of 1435-6 – and what great pertinence that treatise might have had to Gombrich’s own ostensible, object of inquiry: over and above the great virtues of colours in painting, Alberti maintained, the uses of black and white were sovereign:
It is worth all your study and diligence to know these two [black and white paints] well, because light and shade make things appear in relief. Thus white and black make painted things appear in relief and win that praise which was given to Nicias the Athenian painter. They say that Zeuxis, a most famous antique painter, was almost the leader of the others in knowing the force of light and shade; little much praise was given to the others. I almost always consider mediocre the painter who does not understand well the strength of every light and shade in each plane. I say the learned and the unlearned praise those faces which, as though carved, appear to issue out of the panel…”
Could any head have better exemplified the wisdom of Alberti’s observations than Michelangelo’s Erythraean Sibyl? And had Paolo Giovio not celebrated the fact that Michelangelo had given “such great emphasis to the light in contrast to the shade that even knowledgeable artists were induced to believe in the truth of the figures he painted and to see what was flat as solid”? Had not Vasari marvelled at Michelangelo’s precise ability to portray even “the divine majesty” in “the firm and tangible terms that human beings understand”? Had not Vasari further disclosed that Michelangelo “first made models in clay or wax, and from these, because they remain stationary, he took the outlines, the lights and the shadows, rather than from the living model”? In 1525 Giovio had testified that Michelangelo “used a gradually diminishing light to suggest some figures in the distance, almost hidden”. Condivi (in reality a mouthpiece for Michelangelo himself, it has been suggested) held the Prophet Jonah, who sprang from the centre top of the Last Judgement, the “most admirable of all…because contrary to the curve of the vault and owing to the play of the light and the shadow the torso which is foreshortened backward is in the part nearest the eyes and the legs which project forward are in the part which is farthest.” Vasari was no less impressed: “Then who is not filled with admiration and amazement at the awesome sight of Jonah…The vaulting springs forward, following the line of the masonry; but through the force of art it is apparently straightened out by the figure of Jonah, which ends in the opposite direction; and thus vanquished by the art of design with its lights and shades, the ceiling even appears to recede.”
Above, top, Fig. 44 (detail) and 45: Cornelis Bos’ copy of 1530-50 of Michelangelo’s (now lost) Leda and the Swan.
One of the miracles of drawn copies in black on white is the virtuosity and precision with which tones can be calibrated, orchestrated and fixed. Not only does this copy convince us that Michelangelo had used cast shadows on his (late) panel painting, but that he had indeed employed tones as a means of establishing aerial perspective: note how the two putti (as so often on the Sistine ceiling) are set in deep shadow and themselves toned down markedly vis-a-vis the limbs of Leda. Does the artfully thrown (and shaded) drape behind the action not itself testify to a vast indebtedness to this picture, by Bronzino in his great allegory of c. 1540-5 Venus, Cupid, Folly and Time?
Above, Fig. 46: the National Gallery’s painted copy of Michelangelo’s Leda and the Swan, as seen in 1964.
Giampietrino’s Neglected Testimony, Part II
Above, Fig. 47: The National Gallery’s Christ carrying his Cross by Giampietrino, c.1510-30, oil on panel.
The significance of this painting by a close follower of Leonardo has been underplayed at the National Gallery and more generally overlooked by art historians. (For a fuller discussion, see “The National Gallery’s £1.5 billion Leonardo Restoration”.) It has an especial significance with regard to Gombrich’s 1995 National Gallery exhibition on cast shadows in Western painting.
The Leonardo Connection
Giampietrino was a close and trusted associate of Leonardo. He painted the full sized copy of the Last Supper that the Royal Academy loaned to Milan so that it might inform the massive amounts of repainting that took place during the last restoration. Note that this picture consists of generally dark values against which the figure is (relatively) brilliantly illuminated. The light does not fall on Christ as if through some hypothesized cloud or mist. It does so dramatically and selectively. A trio of brightest lights pick out Christ’s right brow and cheek, his shoulder, and his forearm – across which, at the wrist, the dramatically cast shadow from his shoulder falls in defiance of Leonardo’s injunction to avoid clashing outlines of shadows and lights – much as it was ignored by Raphael on the Christ’s left arm as seen in Fig. 20. There was a peculiarly poignant irony in Gombrich’s failure to attend to the testimony of this painting.
While Gombrich’s show was running, this painting was one of two Giampietrinos undergoing restoration and technical investigation. This painting confirmed (for reasons given opposite) that Gombrich’s objections to the National Gallery’s cleaning policy during the 1950s and 1960s had been perfectly well founded. Those findings were published the following year in the National Gallery’s annual Technical Bulletin but the Gallery neglected to draw Gombrich’s attention to this vindicating research (see below, left).
The Contorted Testimony
Having contended, against so much contrary graphic and pictorial evidence, that cast shadows in painting had popped out of existence during the High Renaissance, Gombrich then claimed, that they re-emerged every bit as swiftly in the painting of Caravaggio as they had disappeared after Masaccio. That Gombrich’s method here should have been so profoundly “un-Gombrichian” was sad to behold, but such was his esteem and aura that he appeared to sweep all along with him.
Credulous Critics
It seemed as if the merest incantation of the art term that has become such a fetish in recent scholarship – Tenebrism – could dissolve all critical faculties. Richard Cork of the Times, a strong supporter of the Sistine ceiling restoration (and that of Leonardo’s Last Supper), swallowed and regurgitated the specious bait whole:
A superb small show at the National Gallery, where the eminent art historian E. H. Gombrich opens our eyes to the shadows cast in Western art. Surprisingly few painters included shadows in the Renaissance for fear of spoiling the harmony of their compositions. But then Caravaggio arrived, acting like a dramatic lighting director who revels in extremes of brightness and gloom…The show is a quiet revelation, which makes us look at the rest of the National Gallery’s collection in a new light.”
Alessandro Conti on Domenico Carnevale’s Match with Michelangelo:
Above, Fig. 48a: Michelangelo’s Noah’s Sacrifice before the last restoration, and as published in Alessandro Conti’s “History of the Restoration and Conservation of Works of Art”, London, 2007. Large sections of this passage had fallen away when the ceiling was only 53 years old. The losses here were repaired (as with that shown in Fig. 6) by the painter Domenico Carnevale. Conti described Carnevale’s repairs in the following terms:
As a result of the subsidence of 1565, an actual reintegration of the intonaco [and hence paint layer] had been necessary in the vault painted by Michelangelo. Between 1566 and 1572, the vast loss in the intonaco in Noah’s Sacrifice was made good by a little known painter: Domenico Carnevale da Modena. If one examines the restoration without insisting on a comparison with Michelangelo’s original, it is difficult not to be impressed by the qualities of this 16th century master. For the reconstruction of the figures, it is possible that he was able to make use of drawings and other graphic documentation, whilst in the handling of the paint he showed the ability – particular to restorers – not to imitate the original technique, but to make allowances in his integration for his work to be seen from below. To do this, Carnevale used large strokes, as featureless as possible, with which he reconstructed an image which is somewhat anonymous in as much as it did not have any distinctive handling characteristics of its own, but which succeeded admirably in fitting in with the original paint.”
Given the close and effective matching of values in this large section of painting, we can all the more confidently take the presently seen mismatch between Carnevale and Michelangelo’s work at Fig. 6, to be a confirmation of lost original secco painting in that zone. A similar mismatch emerged in this zone (as seen below in the leg at Fig. 48b). Although the mismatches are not as pronounced in flesh sections as in draperies, we can see that Carnevale’s repair in buon fresco to the upper leg no longer matches the surviving general tonality of the lower leg. The restorers have claimed that this mismatch is indicative of the general levels of dirt on the ceiling at the time. Even if that were true, it would not account for the shaded modelling on the sides of the upper leg with which Carnevale had effected the seamless match with Michelangelo’s then surviving passages of painting, as seen above at Fig. 48a.
Damage to the Sistine Chapel’s Cycles of Painting:
Above, Figs. 49 (top) and 50: It is easiest to demonstrate injuries with details, but the greatest injury done the Chapel was in terms of the relationships that had been established through time between the larger component parts – the decorated surfaces of it walls and ceiling, to which, too little attention has been paid. The promotional hype that accompanied the restoration as it ran into opposition, sold a single narrow, partial, pictorial narrative: that of the Glorious Recovery of Unanticipated Original Colouring. If we pan out from the single technical proof of injury to Michelanglo’s paintings, the repair made by Carnevale (above, top Fig. 49) – we see above at Fig. 50 how this group of figures, before cleaning, had played a secondary role in an outer (relative) darkness. Moving down to Fig. 51 below, we see how the centrepiece of the (curving triangular) section in which they were set, consisted of the astonishingly inventive and brightly lit figure of the crucified Haman.
Above, Fig. 51: This view of a corner of the chapel before the last wave of restorations gives some indication of the disruption of the living, accreted history of the interior. On the right of the photograph is the wall of the Last Judgement. It will be noticed that this wall is not architecturally linked to the chapel’s side wall. This is because in preparing the wall for his great painting, Michelangelo obliterated all architectural continuities (blocking in windows and even obliterating some of his own earlier painting – the two lunettes around the original windows), so as to prepare a single flat “canvas”, as it were, for himself. To the left of the altar wall we see the survival of chapel’s architectural features. It is striking how, before restorations, this wall had broken down into horizontally discrete architectural zones or bands with distinct pictorial/decorative characters. The bottom zone (not visible in the photograph but included in Figs. 53 and 54, below) consists of a simple trompe l’oeil depiction of hanging drapery. On this section, the Raphael tapestries, the cartoons for which are housed in the Victoria and Albert Museum, London, are occasionally displayed. On the section above them (as seen here at the bottom), are individual scenes painted in their own perspectives which “puncture” the surface integrity of the wall with their aerial depths. They are however, bound together by emphatic framing sections of illusionistic architectural decoration that partially re-assert the architectural integrity of the wall. Above that band there is a sequence depicting pairs of former popes that flank each window. In this passage the integrity of the wall is asserted generally but periodically punctured by the illusionistic niches which house the figures of the popes like sentries in their boxes. Immediately above that tonally light and rather decorously treated band, Michelangelo and pictorial fireworks commence. Michelangelo ruptures the (variously) maintained architectural integrity of the wall in two key respects. He peoples this lower band of his painting (the lunettes – the sections of wall that surround the windows) with seated figures of a greatly increased scale and vastly more monumental treatment. Crucially, he situates these giant figures (the ancestors of Christ) in optical recesses that push the walls backwards. Against these perceptually re-situated walls, Michelangelo cast giant shadows so as further to assert both the monumentally substantial physical presence of the figures and their “commanding” occupation of their own space and their own lighting systems. The zone above constitutes the beginning of the vault of the ceiling, and on this section, resting above the junctions between the lunettes, Michelangelo placed his most monumental figures of all, his twelve Seers comprised of seven Prophets and five Sibyls. The consequence of all this, was that before restoration there existed a kind of archaeological stratification of historically and artistically separate layers with distinct conceptual/architectural/pictorial characters – a living history. What uncomprehending violence was to be done to those accreted variations in just a couple of decades.
Above, Fig. 52: Here we see a wall/ceiling conjunction after cleaning and its then relationship with the not-yet cleaned Last Judgement. The most striking feature here is the extent to which the wall/ceiling paintings have been “de-materialised”; the extent to which the surfaces of the building are exerting their own presences more strongly than before.
As in so many instances and regards, Charles Wilson provides an invaluably informed and visually acute firsthand witness:
Before entering upon the subjects of Michelangelo’s method of painting or principles of colour, the disposition of the chiaroscuro, which he has maintained throughout the whole of the frescos, must be noticed.
The light proceeds from the painted apertures in the ceiling and falls with equal diffusion downwards on all sides.
The horizontal shadows of the architecture are very precisely and decidedly marked, but the angular cast shadows are are modified and softened because otherwise they would have confused with their sharp angles, the general decorative divisions of the design.
On the other hand the shadows cast by the figures which sit in front of the white marble arch, with its piers cornice and moulding, are painted with a Rembrandt-like vigour, and must at one time have given those figures complete relief against the bright and fair semblance of marble, now so dingy and so unlike what it has been.
The backgrounds of the lunettes are darker than those of the figures of the vault, as are the grounds of the merely ornamental figures in the angles above, and those below the Prophets and Sibyls form a basement to the brilliant chiaroscuro of the arcade.
The effect of the chiaroscuro in the scenes in the open panels has been very aerial, increased by the powerful light and shade of the figures close to those openings.
When first painted, the arrangement of the chiaroscuro must have produced a brilliant effect, now centirely obscured, but which no doubt might still be in a great measure restored…”
Note, however, that Wilson had complained of dirt, dust and cobwebs upon the paintings but not of “glue-varnishes” slathered on by persons un-named, unknown and of whom no records exist (as was admitted to us in 1990). The glue/size painting was easy to identify and was almost entirely by Michelangelo’s own hand. Note also that, having described the injuries to the secco work made by an earlier restorer, Wilson was especially concerned that any attempted cleaning might inflict further injury on the highly water-sensitive size-painting.
The Persisting Atmospheric Pollution
Above, Fig. 53: Visitors thronging the Sistine Chapel as shown in the 21 December 2012 Guardian (Photograph: Oote Boe Ph/Alamy). It may well be the case that the apparently bleached-out condition of the wall and ceiling paintings is something of a “trick of the light”, but to our knowledge, no photograph of the chapel taken before the last restoration ever showed anything approaching this general tonality. And that is for a good reason: everything that had been found on the surface of the frescoes was removed, including Michelangelo’s own size painting with finely ground black pigments. This photograph also testifies without any ambiguity to the densely packed throngs of visitors (up to 20,000 each day, it was then said) whose presence is converting the chapel’s micro-climate into a toxic environmental stew that threatens to consume what has been left of the frescoes.
Below, Fig. 54, Visitors thronging the Sistine Chapel as shown on the 21 May 2013 Mailonline where it is reported that visitor numbers can now reach as many as 30,000 a day.
The National Gallery’s Stripped-Down Paintings:
Above, Fig. 55: Gombrich included the National Gallery’s Pontormo of c. 1518, Joseph with Jacob in Egypt, in his “Shadows” exhibion. It was a curious “own-goal” choice, given that it abounds with cast shadows. Had Gombrich wished to make another point, he might have drawn attention to the debilitating changes inflicted on this work in the name of its “restoration”.
Above, Fig. 56 (top) and 57: The detail of the Pontormo immediately above and as included in Gombrich’s 1995 exhibition, looks very different from its earlier pre-restoration self (as seen top). The details shown above and below left were photographed for a book of details from pictures in the National Gallery in 1938 by its then director, Kenneth Clark. Clark’s details were re-photographed for new, 1990 edition of his book. The then National Gallery director, Neil MacGregor, noted that many of the pictures had since been cleaned and that Clark himself had been “fearful of what might be found if the golden veils of dirt and varnish were ever to be removed.” Many of the paintings were now, MacGregor noted, “different in critical respects from the paintings Clark discussed”. MacGregor further noted that the reader able to compare the plates in the two editions “will decide how much is gain, how much loss” but he gave no clues as to losses or gains. A crucial difference between the before and after cleaning states is the grievous loss of the former brilliant orchestration of lights and shades which had constituted such a proof of Pontormo’s indebtedness to Michelangelo.
Above left, Figs. 58a and 59a, details before cleaning; above right, Figs. 58b and 59b details after cleaning: It is evident in these further details, that this painting endured much restoration treatment after 1938. It was cleaned (in secret) during the Second World War in 1940, and again in 1981-82. In the latter cleaning “discoloured varnish and retouchings” were removed with “propan-2-ol and white spirit”. This was reported to have left in place “a thick greyish layer of surface dirt and varnish remnants”…It was removed with “a potassium oleate soap”, and the whole was finished off with “pigments in Paraloid B-72″ and a “Ketone-N” synthetic varnish. In the details of the boy’s head we see how the picture has been left more transparent, more like its own Infra-red photographs, as underdrawing now floats into view.
The Mutilation of Michelangelo’s Finest Sibyl:
Below, Fig. 60: The Libyan Sibyl, before cleaning (large) and after cleaning (inset). With reference to Fig. 4, above, note the catastrophic removal of dark toning and shading around the Sibyl’s right foot, from which formerly sprang such a vivid cast shadow. The final stages of Michelangelo’s painting on this great figure (and all others on the ceiling) were taken for varnish and removed in their entirety on this (official) prescription:
…Removal of retouchings and repaintings with a mixed gelatinous solvent, consisting of ammonium bicarbonate, sodium bicarbonate, Desogen (a surf-actant and anti-fungal agent), carboxymethylcellulose (a thixotropic agent), dissolved in distilled water. Mixture acts on contact. The times of application, rigorously measured, were: First application: 3 minutes, followed by removal, washing with water. Left to dry for 24 hours. Second application: 3 minutes, followed by removal, washing and leaving to dry as before. If necessary, and locally only, small applications, followed by plentiful final washing. In the case of salt efflorescences consisting of calcium carbonate, there was added to the solvent mixture a saturated solution of dimethylformamide…”

The Sistine Chapel Restorations, Part II – CODA: The Remarkable Responses to Our Evidence of Injuries; and Thomas Hoving’s Rant of Denial

28th March 2013

Before considering the third and concluding part of our examination of the Sistine Chapel ceiling restoration, it might be helpful to note the responses made to the first two posts (“Setting the Scene, Packing Them In” and “How to Take a Michelangelo Sibyl Apart, from Top to Toes”). Without exception, these have comprised outright expressions of support and/or of indignation and distress at the fate of the frescoes. Such phases as “I had no idea”, “I was horrified to see” and “that things were so bad” abound. Serious and intelligent websites have reported our accounts in similar terms. As is discussed below, no one has challenged our evidence of injuries and everyone who has responded has been shocked and alarmed by it.

Bob Duggan on the Big Think site expressed this concern with precision: “When I learned that my very breath and perspiration could contribute to the slow destruction of the frescoes, I felt sad. However, when I read Art Watch UK’s accusation that the Vatican undertook a 20-year restoration project of the frescoes ‘in full knowledge that the stripped-down bare fresco surfaces would thereafter be attacked by atmospheric pollution unless given some other protective covering’ (which has not yet happened), I felt rage over the local mismanagement of a global cultural treasure…” Duggan added that he was “reminded of a similar, more recent restoration fiasco involving Thomas Eakins’ The Gross Clinic. Years after the artist’s death, overzealous conservators stripped away darkening varnishes applied by Eakins to reveal the brighter colors beneath that were more in line with the Impressionism then en vogue.”

Ikono, an organisation dedicated to democratizing art through the production and broadcasting of short films that present art to the wider public sphere, reported that “ ‘The Vatican authorities are in conservation crisis today because they stripped the Sistine Chapel frescoes bare in the 1980s and 1990s. They did so against material and historical evidence that Michelangelo had finished off his frescoes with additional glue or size-based a secco painting,’ writes Artwatch in an excellent two-part article on the Sistine Chapel Restorations…”

Our case was re-presented in the pithiest form imaginable on the Left Bank Blog: “OY! According to ArtWatchUK: ‘The Vatican authorities are in conservation crisis today because they stripped the Sistine Chapel frescoes bare in the 1980s and 1990s. They did so against material and historical evidence that Michelangelo had finished off his frescoes with additional glue or size-based a secco painting. That original, autograph material was removed in full knowledge that the stripped-down bare fresco surfaces would thereafter be attacked by atmospheric pollution unless given some other protective covering. An attempt to coat the frescoes with synthetic resin (Paraloid B72) was abandoned leaving some surfaces clogged and the rest unprotected. The authorities then promised to install hi-tech paraphernalia that would somehow prevent the polluting atmosphere from making contact with the Chapel’s painted walls and ceiling. As was shown in our previous post, that cockamamie promise was not delivered. Today, in a chapel increasingly over-crowded with paying visitors, these stripped-down frescoes stand in greater peril than ever.'”

A number of questions arise. If the import of the evidence we have assembled over the past 23 years is so clear to so many, why does it have so little traction with the authorities who sanctioned the affronting restorations? Does the absence of any challenge to our evidence mean that everyone is now (privately if not openly) persuaded that – quite aside from the present and ongoing environmental assaults within the chapel – Michelangelo’s painting has indeed been gravely and irreversibly injured artistically, in terms both of its individual component parts and its general orchestration of effects? Or does it show that the authorities, in pursuit of their own interests, are now impervious to and politically insulated against any criticism?

When we first began making this case over two decades ago in the dark pre-digital era, the ink was scarcely ever dry on our criticisms before someone or other claimed that our comparative photographs were misleading; that old painted, drawn, or engraved copies of the ceiling were not to be trusted and had no force as testimony; that we were technically ignorant, or victims of “culture shock”, or agents of mischief – or worse. Could it really be, as it still sometimes seems, that no matter how grave and persuasive the evidence of injuries might be, there exists a wider disabling public resignation and conviction that nothing might today impede the lavishly funded, sponsorship-attracting, Conservation Juggernaut?

To be institutionally specific and somewhat blunt: could it be that the Vatican authorities today think it better to continue sheltering behind a fantastical fairy story of the transforming powers of Wicked Soot and Imperceptibly Darkening Varnishes, than to concede a professional misjudgement made by a small group of in-house experts over a third of a century ago?

Our colleague in France, the painter and the President of ARIPA (The Association Internationale pour le Respect de l’Intégrité du Patrimoine Artistique), Michel Favre-Felix, adds weight and urgency to these considerations with a two-fold reaction. In the first instance, he too was startled by our further evidence of “this incredible statement by the chemist: ‘Ammonium carbonate alone tends to tone down colours…sodium carbonate livens them up'”, and the little-noticed admission of the ferocity of the cleaning agent AB 57 by the chief restorer and co-director of the restoration, Gianluigi Colalucci: “Here’s a tiny patch where I left it on too long. In this little experimental patch you see completely solid violet paint, but around it you can see the gradations of dark and light, which are the shadings of Michelangelo’s own work”. As Favre-Felix notes, whenever a given chemical is known to have even the slightest effect on the original colours, it is rightly forbidden to use it.

His second and generous reaction was to offer further visual corroborations in the form of evidence produced for ARIPA’s journal Nuances of other damages made on the monumental figures of the Sistine Chapel ceiling. The injuries to one of these, the Cumaean Sibyl, are of great strategic significance in our joint battles. That is, we have just shown in our two previous posts the gross damages inflicted on two of the greatest figures that came at the end of Michelangelo’s cycle when he was at the height of his conceptual, painterly and figurally inventive powers – his Libyan Sibyl and his Prophet Daniel (see Figs. 2 and 3). To that catalogue of injuries, the further evidence of this third case must surely now establish an indisputable and irresistible critical mass? Of the ceiling’s twelve alternating Prophets and Sibyls that constituted Michelangelo’s most heroic monumental and spiritually expressive achievement, we can now demonstrate how three in a row of these painted colossi suffered grievously. Statistically, a sample of a quarter might be considered sufficient to make a general case? We could, God willing, pursue the evidence further if necessary, but is it not now time sufficient for the Vatican to confront and address past heritage preservation errors and desist from what would otherwise constitute an effective falsification of scholarship and art history?

The Portuguese online newspaper Publico reported our criticisms of the Sistine Chapel’s restorations on the second of March. Professor Charles Hope, a former director of the Warburg Institute, was quoted in further criticism of the restoration. The present director of the Vatican Museums, Antonio Paolucci, conceded a pressing need for ameliorative environmental measures which he said would shortly be announced. Unfortunately, he nonetheless and bullishly defended the restoration itself as one which will last for centuries – even before any measures have been announced. (We understand that since those comments were made, the promised announcement has retreated from this April to “the end of the year”.)

If we might at least now be sure that the Vatican is aware of our criticisms and evidence, we recognise that for its part, the Vatican will also appreciate the potential material and political risks of abandoning defences of the restoration. Visitors to the chapel greatly swell attendances to the Vatican Museums. In 1976, about 1.3 million people visited the museums. By 2007 the number had reached nearly 4.3 million, netting some $65 million and providing the Vatican City with its most significant source of income. An admission of error would also embarrass the many major players within the international art world who proclaimed a Revolutionary Restoration in the 1980s. To what degree of embarrassment might be sensed in an ill-tempered and defensive outburst by (the late) Thomas Hoving, a former director of the Metropolitan Museum of Art, New York, in a filmed interview for a portrait of the late painter Frank Mason, an early critic of the restoration and a founding member of ArtWatch International.

Thomas Hoving and selected dialogue from an interview in the film A Light In The Dark:

00:53:02 – Thomas Hoving:

“He doesn’t know what he’s talking about (Frank Mason). There’s a guy at Columbia, some professor who’s been screeching about this for years. (pause) Turns out that he just doesn’t know what he’s talking about. (pause) Do you think Michelangelo was honestly going to deliver it to the Pope something that looked dirty?! (laughs) His marble was going to look gray, his marble was going to look blackened out?! You think that he really mixed his fresco to look like that?!”

01:07:01 – Alexander Eliot:

“I wouldn’t say that the Sistine ceiling had been destroyed myself. I wouldn’t use that word. I would say that it had been desecrated.”

01:07:24 – Thomas Hoving:

“I was part of the desecration personally, if this idiot is right. I am part of it so he ought to put my name on it. (pause) I was invited by the man who cleaned it, Paolucci – whoever, (pause) [Gianluigi Colalucci was the chief restorer and co-director of the restorations, which ran from 1980 to 1994. Antonio Paolucci became the Director of The Vatican Museums in December 2007. – Ed.] to come up in the rickety elevator (makes sound effect of elevator) all the way to the top, and he gave me a beautiful fresh sponge, dipped it in the solution and (he) said OK clean. And they were finally doing the Separation of Earth, (uh) Separation of Light and Darkness, the last one. They started with the Flood and worked backwards. I said, ‘What?’ He said, ‘Ya, try it.’ I went (reaches up) ‘shooo!’ (wiping motion) And this thin film of black just disappeared. “It was just built up soot over hundreds of years from the stoves that they used to drag in there when the Cardinals all had to meet. That’s what they all did. They had little cubby holes, their servants had cubby holes, they had tents, they had bunks, full service catering, and stoves. “And fresco is impervious to anything other than being blasted by (uh) laser beams you know (does sound effect) out of Star Wars. Not only did they not desecrate or ruin it, they didn’t do anything to it that wasn’t there. So the guy is full of shit (!) if he said that they damaged the Sistine ceiling in any way, they didn’t! I know it. I was there. I cleaned about eight inches of the Sistine ceiling – personally!”

01:10:11 – Thomas Hoving:

“It’s not a controversy, the guy is full of it (Alex Eliot) He’s never been there, he’s never seen it. Did he clean a part of it?”

Interviewer Sonny Quinn:“He made a film…”

Thomas Hoving: “Big deal.”

SQ: “He was close enough so he…”

TH: “Close enough? It’s about 55 feet, give me a break!”

SQ: “…they built scaffolding for him and he was there for six weeks…”

TH: “During the cleaning?”

SQ: “No, before the cleaning…”

TH: “Ya, so?”

SQ: “Well, he wanted everybody to examine his film and…”

TH: “Ah the guy is just full of it…”

For the record (once again), in 1967 the art critic and writer Alexander Eliot and his wife Jane Winslow Eliot spent over 500 hours making a close-up documentary film of the ceiling, The Secret of Michelangelo, Every Man’s Dream. Eliot was up there on the scaffold, every bit as close to the ceiling as Hoving was to be – and for much longer. On 20 May 1985 Eliot had pleaded with the Vatican’s Secretary of State for him to view the Vatican’s own copy of the Eliots’ film and to “have it stopped at the images of the Ancestors [on the lunettes]. Compare what it proves was there against what’s left today”. That precious record of the unrestored ceiling awaits a re-showing. One can only wonder why the Vatican never pressed the testimony of that filmed footage of the pre-restoration ceiling in support of the later cleaning.

For footage of the cleaning itself in progress, see the Ikono site mentioned above which links to three short films. The narrations of all are unspeakably hagiographic and tendentious: critics of the restoration are said to have been “divided”, while the restorers displayed a “passion for their task that recalls that of Michelangelo himself”. The restoration’s outcome is said to “speak for itself” and to have answered “all but the most severe critic”. Most brazenly of all, an outing for that old canard: this restoration had provided “rich opportunities for study”.

We should perhaps resign ourselves to the possibilty that the Eliots’ film may never be aired again – but it will never be possible to expunge all the photographs of the unrestored frescoes that permit the kind of directly comparative visual analysis routinely conducted on this site. Such comparisons truly do “speak for themselves” because they permit like fairly to compare itself with like. For those with eyes to see, such photo-comparisons will forever tell the same heart-breaking story: a misconceived, technically aggressive restoration inflicted grievous injuries on Michelangelo’s art.

CAN YOU SEE WHAT IT IS YET?
Above, Fig. 1: A cleaned fragment of Michelangelo’s Sistine Chapel ceiling – but from where?
Above, Fig. 2: A section of Michelangelo’s ceiling before restoration. At the bottom, we see three of his great monumental figures. Two of these, the Libyan Sibyl and the Prophet Daniel, were discussed in the previous post in terms of the great injuries they suffered during restoration. The third figure in the row is that of the Cumaean Sibyl, whose restoration fate is examined below.
Above, Fig. 3: The Cumaean Sibyl seen centre between the Prophet Daniel (left), and the Prophet Isaiah (right).
Above, Fig. 4: The Cumaean Sibyl seen before restoration. Note especially the richly modelled (i.e. shaded) interlocking forms of the two nude boys arms; the dramatic range of tones in evidence on the Sibyl’s monumental left arm; and, the deep, darkly hollow, sculpturally punctuating pool of shadow bounded by the boys’ elbows and the Sibyl’s upper right arm. In general terms, note the extraordinary sculptural fusion of the three figures and their (seeming) collective occupation of a real and palpable space in front of the architectural wall behind them. The plastic lucidity of this group had survived for nearly five centuries. To alert observers it had remained what it had been initially to Michelangelo’s contemporaries: astounding. Note the brilliance with which the twin, linked left arms of the boys had mimicked and echoed in dutiful witness the colossally concentrating anatomical transmission of the Sibyl’s intellectual power and prescience via her own gigantic (and otherwise overblown) left arm. The great Michelangelo scholar Charles de Tolnay must surely have had this figure in mind when he wrote of how Michelangelo had, in the painting of his ceiling, rendered all preceding art “an imperfect preparation” for it, and all the art that followed it “a decadence”.
Above, Fig. 5: The Cumaean Sibyl seen after restoration. There are many differences between the two states and none of the recorded changes has proved beneficial. Note first the transformation that took place in the hanging bag holding manuscript papers, the post-restoration state of which features as our mystery object at Fig. 1. Note the obliteration of the shading which had explained the forms and spaces of the architectural elements on which the Sibyl is enthroned. Note how the escalating, sculpturally expressive tones that ran around the Sibyl’s left arm turning its forms in space have been vitiated by the emergence of a linear highlight on the arm’s underside which overly asserts the drawing of the figure and undermines its calculated tonal simulations of real forms in real spaces. That assertion of marks-on-a-flat-surface now recurs throughout the group and, to echo René Hughe, imparts a distinctly modernist and ahistorical character on an iconic work in which the artist had originally and triumphantly done the greatest violence to the “integrity” of the picture surface on which it had been composed.
Above, Fig. 6: The Cumaean Sibyl seen before restoration. Note the varieties of shades of green that were to be seen on the board of the book and on the hanging bag of papers. Note the highlight on the left side of the cushion (or cushioning drapery) that supports the giant book and the strong dark shadows to left and the right of the hanging bag. Note how the glazing on the drapery had not only darkened and sharpened the sculptural forms (by turning surfaces away from light sources) but had also intensified the hue, moving it away from the tan/orange to a deeper, richer red. We see evidence of a red glazing having been deployed over the base green colouring of the bag, so as to produce the dark shading which is expressive of the forms held within the bag.
Above, Fig. 7: The Cumaean Sibyl seen after restoration. Note the destruction of the varieties of green and with them the flattening of the hanging bag. Note the disappearance of the highlight on the cushion under the book. Note how an abrupt change of hue occurs between the drapery over the leg and that under the book. The justification of the changes induced by the restoration has been that (- as pugnaciously described by Hoving, left) nothing other than black filth had been removed and that this removal had been made expressly to liberate cleanliness and brilliance of colouring. What, then, must the restorers have thought that they were doing when these changes of hue occurred? For that matter, what must the Japanese photographers have thought was happening through their recording lenses?
Above, Fig. 8: A drawing (detail) of the Cumaean Sibyl made by Rubens in 1601, showing the bulging and the shading of the bag. If all the features that were sacrificed in the cleaning really had been misleading impressions created by gradual accumulations of soot and darkening varnishes, as the restorers claimed, the process would have to have begun with a very dramatic spurt between 1512 when the ceiling was unveiled and 1601…and then done nothing much at all for nearly four hundred years.
Above (top), Figs. 9 and 10 showing catastrophic changes of hue and tones. Above (centre), Figs. 11 and 12, showing the catastrophic losses of shading (lights as well as darks) during restoration. The method of the restoration has only ever been defended in general terms, when what is required is some explanation for the various local changes that occurred throughout the ceiling. Because Michelangelo had made elaborations and modifications with paint applied to the dry frescoes, in varying degrees, some parts of the ceiling were more badly affected by their removal than others. It was for the restorers first to acknowledge the changes that were occurring under their sponges and then to explain them section by section. This was never done. If we reverse the sequence as directly above at Figs. 13 and 14, the question then becomes: If Michelangelo had left the bag as is now seen after the restoration (left) at Fig.13, what non-man made process could account for the changes that had occurred by 1601 and then survived without further change until 1980?
Above, Fig. 15: An engraved copy of the Cumaean Sibyl by Cherubino Alberti made before sometime before 1615 which shows the bulges on the bag much as copied by Rubens. The engraving is also eloquent – as so many copies were – on the generally dramatic “Trompe l’oeil” effects created by Michelangelo, one of the most crucial of these being his posited brilliant lighting sources which appeared to have cast shadows from real figures onto surrounding surfaces. These devices are virtually universally recorded in countless copies throughout the centuries and regardless of stylistic changes between artists. A simple cleaning of the paintings would have enhanced their surviving tonal contrasts and thereby intensified the illusions. Instead, what we see along with a compression of these tonal values is a reduction of Michelangelo’s once revolutionary sculptural and spatial effects. Thus was Michelangelo’s original celebrated vanquishing of the ceiling’s complex surface geometries itself vanquished by the actions of technicians.
Above, Fig. 16: An aquatint copy of the Cumaean Sibyl made c. 1790 by Giavanni Volpato, again showing the rich modelling on the bag, the richly modelled arms of the boys first seen in the above copies nearly two centuries previously. Below, Fig. 17: A still from the animated film Frankenweenie. In our post Frankenweenie – A Black and White Michelangelo for Our Times we held that Tim Burton’s vivid black and white photographic images of hand-made models participated brilliantly in one of Western art’s most distinguishing traits. From Alberti to Ruskin, artists have deployed tonal gradations so as to conjure three-dimensional effects on flat pictorial surfaces. Until the 1960s every art student learnt to manipulate tonal values in this fashion. Tragically, such conventions have been discarded in (most) fine art education and in much of today’s fine art practice. Fortunately, those ancient empowering lessons have not been lost in Cinema and Photography. In Burton’s hands they have found singularly powerful expression. It is Art’s great tragedy that Michelangelo’s stupendous and pioneering exemplar of plastic illusionism should have been injured by its intended restorers.

The Sistine Chapel Restorations, Part II: How to Take a Michelangelo Sibyl Apart, from Top to Toes

4 March 2013

I must confess I harbour a lingering almost subconscious fear that someday someone will come, unexpectedly, with a really intelligent observation that will show all of us to have been blind.” ~ Gianluigi Colalucci, 1990

We were startled when the Vatican authorities admitted that Michelangelo’s Sistine Chapel frescoes are in greater peril than at any point in their history. Powerful art institutions rarely broadcast their own embarrassments. More often, they see off their critics by sitting tight, quietly briefing journalistic proxies and…continuing to be. Welcome as was the acknowledgement of the problem by Antonio Paolucci, director of the Vatican Museums, casting the Chapel’s paying visitors as the principal cause of the present crisis, masked greater institutional responsibilities.

The Vatican has yet to acknowledge that this environmental crisis arose as a direct consequence – and within just two decades – of permitting the Chapel’s ancient frescoes to be used as a test bed for the then new and highly controversial cleaning agent “Mixture AB 57”. And, despite the brouhaha over toxic visitors, there remains no hint of acknowledgement that the restorations of the 1980s and early 1990s proceeded on an art critical misreading which, in addition to stripping the fresco surfaces bare and leaving a chemical time-bomb within the Chapel, inflicted grave and irreversible artistic injuries on Michelangelo’s paintings – see right.

On the cleaning method’s toxic conservation legacy, we had precisely warned in 1993 that: “even if the Vatican team were to concede that the brilliance of Michelangelo’s new colours is a chemical deceit purchased at the cost of a physical and chemical weakening of the frescoes, the dispute would not be laid to rest. The need to avoid further deterioration would still be there.” (James Beck and Michael Daley, “Art Restoration: The Culture, the Business and the Scandal”, Chapters III and IV.) In similar vein we can now say that today’s promises of dramatic technical “improvements” are simply recycled 1980s assurances that, at best, remain of a palliative nature. Even when promised the first time around, the Vatican authorities had admitted to us (see below) that the measures could not fully solve the then already pressing environmental problems unleashed by the restoration’s experimental method.

The Experimental New Picture Cleaning Method

AB 57 was developed by Professor Paulo Mora and his wife Laura Mora, chief conservators at Rome’s Istituto Centrale del Restauro, for cleaning stone buildings. It comprised: “a mixed gelatinous solvent, consisting of a solution of ammonium bicarbonate, sodium bicarbonate, Desogen (a surf-actant and anti-fungal agent), carboxymethylcellulose (a thixotropic agent), dissolved in distilled water.” Toti Scialoja, a painter and a former professor at Rome’s Academy of Fine Arts, complained that its ingredients were “too powerful – ammonia and soda, the stuff you use to clean your bathtub”. Professor Christoph Frommel, director of the Bibliotheca Hertziana in Rome, described it as “a sharp and aggressive chemical”.

The Moras presented AB 57 as a means of removing insoluble salts and incrusted materials from wall paintings: “If the original surface of the painting is unaffected by water then this mixture will have no deleterious action on it”. Michelangelo’s frescoes did not suffer greatly from incrusted and insoluble salts but they were extensively covered with water sensitive glue/size painting which artists, conservation experts and scholars held to comprise Michelangelo’s own final painted adjustments. An early sign of the wrongness of the new cleaning method came when the restorers abandoned customary claims of a miraculous “recovery” of original and authentic conditions. The use of AB 57 had produced such a mismatch between the cleaned frescoes and the early copies that had been made of them, that the hype had to be bolder and of a different order. As seen in our previous post, the decision to clean with AB 57 had been taken quickly and in express excitement at the prospect of overturning art history itself. This dramatic technology-led change of conservation philosophy was reported in a 1983 Newsweek account: “As recently as 1976 while cleaning paintings by the other artists on the side walls of the Chapel, workers deliberately kept the colours muted so that Michelangelo’s wouldn’t look too faded by comparison. ‘Even then it entered nobody’s head to start on Michelangelo’, says master restorer Gianluigi Colalucci. But when a new cleaning solvent was developed, Colalucci tested it…”

Selling the Surprising AB 57-induced Changes to Michelangelo’s Painting

Having used it, the resulting rupture between the old Michelangelo and his restored self was trumpeted by Fabrizio Mancinelli, the Vatican Museums’ curator and co-director, with Gianluigi Colalucci, of the restoration. Mancinelli claimed in 1986 that the restoration “had brought to light (and will continue to bring to light) a totally new artist, a colourist quite different in character from the unnaturally sombre character who has in the past fascinated generations of historians, connoisseurs and fellow artists…The cleaning of the frescoes has led to the surprising conclusion that the kind of suggestive painting by shadows for which Michelangelo was admired until a few years ago was essentially the product of candle smoke and still more of glue varnishes applied possibly even before the 18th century.” (“The Sistine Chapel ~ Michelangelo Rediscovered”, p. 218.)

Even though no evidence was ever produced of extensive glue applications having been made by restorers, in the early years, art historians and credulous art critics queued to repudiate what one scholar dubbed the “Darkness Fallacy” and the “Sculptural Fallacy” of traditional Michelangelo studies. The proclaimed “New Michelangelo”, however, was an entirely modern chemically engineered artefact, not a scholarly construct. In fact, it flew in the face of the historical record: Michelangelo had been celebrated at his own funeral not for any colouristic brilliance – let alone for, as one critic recently held, the “sharp and acid palette used by Michelangelo in the Sistine Chapel” – but for his “fleeting, sombre colours”. The new art historical dispensation rested on a twentieth century purging of aged, sometimes distressed but nonetheless authentic material. Indeed, it was precisely because this was not a historically-informed recovery of an original state that drums had had to be rolled for “The New Michelangelo”.

It was claimed that this revisionist reading of historical and material evidence had been corroborated “scientifically”. But this was a New Science to sanction a New Michelangelo. Scientific examinations of the frescoes in the 1930s by X-ray and ultra-violet imaging techniques had led to altogether contrary conclusions. It was reported in 1938 that Michelangelo’s “overpaintings were lying quite brightly a secco on the fresco layer itself; these overpaintings proved themselves undoubtedly the painting of the Master himself.” (See “Art Restoration”, Chapter III.) It was further claimed that Colalucci and his colleagues had recovered the original fresco surfaces so deftly that they had preserved its “original” patina and even left a thin layer of dirt above them that would protect the new surface from airborne pollution. Well, we all now know from the present panic in the Vatican that that assurance was not worth a used solvent swab and that a couple of years ago “unimaginable amounts” of dirt were scrubbed off the frescoes by conservators working at night so as not to impede the daytime tourism stream.

The Over-Selling of Conservation Science

Conservation science has its uses but it can never analyse or appraise works of art because Art’s essential properties are aesthetic not material; perceptual not mechanical. Insofar as there might be a science of art, it is to be found in art itself and within artists’ own practices. This is because art consists not so much of materials as of values and the relationships between values that artists’ create and orchestrate, albeit, with materials. These values are aesthetically relative, not intrinsic to materials, and they are continuously appraised and adjusted by artists as they work. Self-criticism, self-analysis and continuous aesthetic appraisal are integral to the making of art. With art, critical and analytical faculties can never be replaced by apparatuses or be donned by technicians. Conservation science might sometimes tell us of what something is made but never by whom it was made.

The Mis-Appliance of Conservation Science

In terms of professional art restoration, conservation science can serve a useful diversionary purpose. The restoration-authorising authorities and art lovers alike can be invited to put aside critical responses on an implicit assurance that some inscrutable but infallible force has guaranteed the probity of whichever of the many conflicting restoration methodologies is being used at that moment. We ArtWatchers are not inclined to be so trusting nor so easily led. In the case of Michelangelo’s Sistine Chapel ceiling, having examined evidence of the cleaning method and its consequences for two and a half decades, and being now armed with the officially published accounts, we are confident that not only can it be shown that Michelangelo’s tonal/plastic systems were recently injured, but that even his very designs, his drawing, his vaunted disegno were repeatedly violated and corrupted.

A Catastrophic Loss of Art Citical Nerve

These losses and violations were not so much unfortunate by-products of an inappropriately aggressive cleaning agent as the consequence of prior and catastrophic failures of art critical judgement and powers of aesthetic analysis. This failure was evident not only within the Vatican’s curatorial, scientific and conservation staffs, but throughout much of the wider international art historical establishment. By effectively agreeing to “de-attribute” what were – and had always been recognised to be – the last stages of Michelangelo’s own work, an overly deferential art historical establishment sanctioned their destruction. For all this (initial) pan-national consensus, the judgement was historically rogue. In 1986, when defending his own restoration, the chief restorer, Gianluigi Colalucci admitted that his professional predecessors’ judgements had been contrary to his own and “not encouraging” to the restoration. That was an understatement: restorers who had worked on the previous restoration (1935-36) had officially and flatly reported that Michelangelo had “finished off a secco”, that is, that he had painted on top of his frescoes when they had dried.

The Testimony of Charles Heath Wilson

Restorers who had worked on the restoration of 1904 had abandoned attempts to clean the frescoes for fear of damaging Michelangelo’s vulnerable work on the surface. Colalucci, greatly in thrall to contemporary “scientific” analysis, dismissed such official reports as “subjective impressions”. He also ignored the testimony of the British painter and fresco expert Charles Heath Wilson who had reported his own close-hand examination of the ceiling in an 1876 book “Life and Works of Michelangelo Buonarotti”. Wilson had found the frescoes “extensively retouched with size colour…evidently by the hand of Michelangelo”. He found that this secco painting “readily melted on being touched with a wet finger and consisted of a finely ground black, mixed with a size probably made according to the usage of the time from parchment shavings.” He further noted, “The shadows of the draperies have been boldly and solidly retouched with this size colour, as well as the shadows on the backgrounds…The hair of the heads and the beards of many of the figures are finished in size colour …These retouchings…constituted the finishing process or as Condivi [Michelangelo’s preferred biographer] expresses it, alluding to it in the history of these frescoes, ‘l’ultima mano’.”

For Wilson, there could “be no doubt that nearly all of this work is contemporary, and in only one part was there evidence of a later and incompetent hand.” Aside from its artistic force, certainty about the secco painting’s antiquity lay in an elegant technical proof: “The size colour has cracked as the plaster has cracked”. It is a matter of record that the ceiling cracked before any restorers touched it. If, as has been claimed, later restorers had repeatedly applied glues, those glues would inevitably have been brushed into the pre-existing cracks. Wilson, who tested the depth of the cracks with a penknife, saw that none had been. Artists like Wilson appreciate that it is impossible to paint over a cracked surface without working the material into the cracks. Wilson was left in no doubt: having been applied when the ceiling was new and not-yet-cracked, these surface glue paints could only have been Michelangelo’s own work, his finishing stages, his l’ultima mano. Normally, restorers recognise that when varnishes or paints can be shown to have run into age-cracked materials this can be taken as a proof of their more recent origins. On this occasion, the restorers failed to recognise the implications of the converse.

The Vulnerability of Michelangelo’s Glue Painting

Moreover, this original secco work, Wilson appreciated, was water-sensitive, having been damaged when “washed by labouring men with water in which a caustic has been mixed”. As to when the alleged restorers’ glue-varnishes might plausibly have been applied, no evidence was forthcoming. In 1996 Colalucci said that although “countless attempts at cleaning and restoration seem to have been made”, only “four are actually accounted for”. The four are of 1566, 1824-25, 1904 and 1935-36. As we showed in our post of 1 April 2011, that first restoration itself provided the clearest possible evidence of Michelangelo having painted shadows a secco. That evidence, taken together with the copies of the ceiling discussed opposite should have been an end to the matter. The last two restorations cited by Colalucci coincide with photographic records and these, too, offer no support for the claimed superimpositions of secco painting and glue-varnishes by restorers.

Perplexed by the Vatican’s unwavering but evidently unsupported insistence that the ceiling had repeatedly been coated with glue “varnishes”, I asked in May 1990: “Does any documentary evidence exist to support the claim that hot animal glue was repeatedly applied to the frescoes over the centuries in order to revive the colours?” Colalucci replied that there was none. In 1986 he had reported a note in a manuscript which described how the ceiling had once been cleaned with linen rags and bread “scrubbing hard, and sometimes when the dirt was more tenacious, the bread was moistened a little” but added “That is as much as it says. The note does not mention at all the use of substances to revive colours or of glue varnish.” (See “Art Restoration”, pp. 74-78.) If, as Wilson discovered, the secco painting dissolved at the touch of a wet finger, an earlier hard scrubbing with wet rags or bread would certainly have been sufficient to cause the injuries that Wilson and others had reported to parts of the ceiling.

A Filmed Corroboration of Wilson’s Testimony

Wilson’s appraisal was echoed from another scaffold a century later. In 1967 the art critic and writer Alexander Eliot and his wife Jane Winslow Eliot spent over 500 hours making a close-up documentary film of the ceiling, “The Secret of Michelangelo, Every Man’s Dream”. Alexander Eliot reported in the April 1987 Harvard Review how “with the exception of the previously restored Prophet Zachariah, almost everything we saw on the barrel vault clearly came from Michelangelo’s own inspired hand. There are passages of the finest, most delicately incisive draughtsmanship imaginable. Michelangelo’s loving depiction of fingernails, eyelids and tiny wrinkles stand in contrast to tremendous swirls of colour…” On 20 May 1985 Eliot had pleaded with the Vatican’s Secretary of State for him to view the Vatican’s own copy of the Eliots’ film and to “have it stopped at the images of the Ancestors [on the lunettes]. Compare what it proves was there against what’s left today”. That precious, now historical, record still awaits a re-showing.

Venanzo Crocetti’s Protests Against the Restoration – as a Sculptor and as a Former Restorer in the Sistine Chapel

In 1989 the sculptor Venanzo Crocetti, who had spent “four full years” working during the 1930s as an apprentice restorer on the scaffold, published three photo-comparisons of the cleaned lunettes in an article in the December Oggi e Domani (“Salviamo Almeno il Giudizio Universale”) – see Fig. 28. Crocetti’s account was detailed and technically informed. He began by explaining how he had appealed unavailingly in 1983 to the director general of the Vatican Museums, Prof. Carlo Pietrangeli, to desist from incurring the “rapid biological degradation caused by the cleaning power” of AB 57. Crocetti flatly dismissed claims that the glues had been applied by restorers. He also testified that as early as 1983 applications of AB 57 had been standardised at 3 minutes each, regardless of local conditions (see below). He complained of the folly of cleaning aggressively in small patches, zones that had originally been made with very broad applications. These glue-paint applications, he noted, had been made chiefly in the shaded parts of the figures and to such artistically selective purpose that Michelangelo’s authorship was beyond question. As a (formerly) supreme case in point, see Fig. 1.

The Effects of the Double Applications of AB 57

Crocetti’s testimony on the AB 57 cleaning method then being used on Michelangelo was particularly damning. He noted that while the first 3 minutes long application left the frescoes looking cleaner, the second on the following day, left them with altered and considerably degraded colours. He believed that the first applications effectively “degreased” the surfaces leaving them open to greater penetration by the second applications. He was convinced that the immediately apparent visual effects of these twin applications would not be their final outcome. He argued that their corrosive actions would continue because of the absorption of the solvents to a depth of half a centimetre. Some days after the second applications he noticed (from the scaffold itself) the appearance of “whitish oxidations of variable intensity” over large zones.

He considered the restorers’ claimed discovery of “stratifications of dirt gathered on the frescoes over the centuries” exaggerated and misleading, and he held that the early photographs of the lunettes by Anderson made the extent of this exaggeration clear – see Fig. 28. He believed that the ferocity of AB 57 made any finely tuned cleaning gradated to meet local conditions impossible. He believed that the greatest injury was to the chief feature of the frescoes – their disposition of lights and shades, and not their local colours. He believed that the restorers, in their pursuit of more intense colours, had penetrated the frescoes to their brighter, less modulated preparative layers. He felt confident that he had seen at first-hand how, with “cleaning”, the figures in the lunettes had been remade, becoming “false in form and colour” alike. He saw that many of the shadows from which the figures had formerly emerged had simply disappeared. He saw that corrections which Michelangelo had, with mastery, made invisible, had been exposed (in particular, see Figs. 11-16). Above all, he confirmed that the condition of the frescoes remained “excellent”, and that this was in part due to the absorption over the centuries of greasy substances of chapel smoke which had “strengthened the colour. Leaving upon it a glittering shift of the lightest varnish [thereby counterbalancing] the aridity and fragility” of old fresco. Having worked on the restoration in the 1930s, he found himself near to despair.

The Invasive Ferocity and Likely Legacy of AB 57

The AB 57 water-based paste used to remove Michelangelo’s size painting contained two “caustics”: sodium bicarbonate and ammonium bicarbonate. Professor Frommel had questioned the method of application: “Who knows if they succeed in cleaning this completely away? No one can prove whether or not it will affect the frescoes in the future. No one can say definitely if they get all of it off.” Consider Colalucci’s own account of the method of application:

The times of application, rigorously measured, were: First application: 3 minutes, followed by removal, washing with water. Left to dry for 24 hours. Second application: 3 minutes, followed by removal, washing and leaving to dry as before. If necessary, and locally only, small applications, followed by plentiful final washing. In the case of salt efflorescences consisting of calcium carbonate, there was added to the solvent mixture a saturated solution of dimethylformamide…”

Chemically Adjusting Michelangelo’s Colours

AB 57, a calcium dissolving solvent, was thus used to remove organic materials with an oven-cleaner like ferocity and speed even though many experts held those very materials to comprise authentic Michelangelo work. Contrary to assurances otherwise, the aesthetic consequences of this stripping extended, as Crocetti had observed at first hand, into the very fabric of the exposed fresco surfaces. This was a serious matter. The Vatican’s research chemist, Nazzareno Gabrielli had explained that AB 57 contained two separate salts because while “Ammonium Carbonate alone tends to tone down colours…sodium carbonate livens them up”. The Moras’ combination, he judged, had “the proper chromatic effect”. So far as we know, it was never explained by what means the “proper” combination for Michelangelo might have been established.

Juggling with dangerous chemicals and processes constitutes professional chic in some restoration quarters. Restorers often claim that a dangerous chemical in “safe hands” is better than a mild one in “untrained hands”. When restorers speak among themselves, the professional conceits are more evident. The IIC Bulletin carried an obituary on Paolo Mora who died on 27 March 1998. He had studied under Mauro Pelliccioli, who restored Leonardo’s Last Supper, and, reportedly, was fond of claiming that he could clean a picture with a broom and drugstore chemicals. When he found himself too busy to clean a large Bellini altarpiece, Pelliccioli enlisted two students and showed them how to dissolve rods of caustic soda in water. He demonstrated his cleaning technique by sweeping a swab of soda over the picture with one hand followed immediately by a “neutralising” swipe with a turpentine swab with the other. Thus enlightened, the students were said to have “cleaned the large painting in a single day”.

The AB 57 Rinse-Water Menace

Aside from exposing the stripped fresco surfaces to the Chapel’s notoriously polluted atmosphere, yet other risks were taken in pursuit of brighter colours. Removing the water-based solvent gel with copious amounts of washing risked, as Frommel feared and Crocetti had observed, depositing corrosive ingredients within the frescoes. The “highly soluble” ingredients were said to have been selected because “they are easy to wash off”. It was certainly desirable that they should be so: carboxymethyl cellulose is known to encourage sodium retention; ‘Desogen’, being a detergent as well as fungicide, is non-volatile and does not evaporate. The Moras had conceded that these ingredients have “the disadvantage of remaining in the painting unless removed after treatment by rinsing with water”.

There are problems with washing, however. First, the rinse water was absorbed deeply into the porous fresco and with it, inevitably, particles of soluble and corrosive ingredients. Twenty four hours were needed for the water to evaporate before a second application of AB 57 could be applied. Second, tap water may contain solutions of sodium, iron, copper, and chloride, and unless it is packed with sufficient calcium bicarbonate, will itself attack the calcium carbonate of fresco. Even distilled water (which is free of impurities) slowly dissolves calcium carbonate and attacks the frescoes’ structure. When challenged in 1991 on having introduced dangerous materials into the frescoes, Colalucci replied: “AB 57…has been greatly tested and is very old. The actual solvent is held within a gel which does not allow the particles of the actual solvent to penetrate the plaster and the colour. However, the gel is removed and only a minimal (if any) percentage might remain which has no influence on the colours.” In 1986 Colalucci disclosed that, at that date “The work was concluded with abundant rinsing, repeated at intervals of up to several months” and that only “The last rinsing was done with distilled water”. Much copious washing was thus carried out with tap water.

Mirella Simonetti on Dangerous Deposits and their Air-Borne Allies

Far from having “no influence”, experts expressly feared that residues deposited within the frescoes by rinsing would react with airborne pollutants and moisture. The restorer Mirella Simonetti held one of AB57’s ingredients, bicarbonate of soda, to be an “extremely damaging” residue because, when combined with the sulphates of calcium and air-borne sulphuric anhydrites, it produces sodium sulphate – a whitish dust which corrodes the fresco and destroys its coloured surface. Simonetti also maintained that the use of EDTA (ethylene diamine tetra acetic acid) within the solvent gel had chemically altered the fresco by causing a “breakdown in the molecular structure [and] bringing about a disintegration [which] in turn causes the division of the components and the discohesion of the lime.” Once weakened in this fashion, the disintegration would continue – and “even water can favour such a process”. Simonetti’s alarm was later vindicated when, tests showed that the compound’s corrosive properties etched the surface of marble into irregular corrugations, scattering light and imparting a deceiving effect of brightness that provided more routes of ingress to airborne pollutants.

Fresco Painting and Its Known Enemies

It had long been recognised that air-borne sulphur attacks fresco. In 1884 the reverend J. A. Rivington explained in a paper delivered at the Society of Arts in London how air contaminated by coal and gas emissions destroys fresco: “The carbonate of lime is converted into the sulphate, breaking up the paint and becoming itself disintegrated in the process of change.” The notoriously contaminated air surrounding and invading the Sistine chapel contains sulphur dioxide from coal-burning, nitrous oxides from car exhausts and hydrogen chloride from incinerated plastics. When combined with rain or condensed water these substances produce sulphuric, nitric and hydrochloric acids respectively, all fiercely corrosive. Water is brought into the Chapel by tourists in the form of perspiration and breathing vapour while breathing itself gives off carbon dioxide.

On 12 December 2012, Corriere della Sera reported: “‘Dust, temperature, humidity, and carbon dioxide are the great enemies of paintings’, Museum Director Antonio Paolucci told reporters in the Vatican, ‘so this threat is something we have to address. The five million tourists who visit the Sistine Chapel each year bring massive amounts of grime and humidity with them, and it is seriously damaging Michelangelo’s frescoes. So starting in the middle of 2013, every tourist will be thoroughly vacuumed, dusted, cleaned, and chilled before admission to reduce the amount of environmental pollution they cause. ‘On entering the chapel, each tourist will be required to pass through a hi-tech vacuum system to remove dust, fibres, skin flakes, hair and other tiny particles, before they are allowed to view the frescoes. At the same time, a special carpet will also clean their shoes, while side vacuums will cool their temperature, to reduce the heat and humidity that emanates from their bodies. The dirt and heat generated by the 20,000 bodies each day has caused grime to accumulate on the paintings, and a thick layer of dirt had to be scrubbed off of the Last Judgment two years ago. This cannot be allowed to happen again.’”

What Goes Round, Comes Round

We have been there before. In “Art Restoration” in 1993 we wrote: “A recent report commissioned by the Vatican on the Chapel’s microclimate noted that the very large numbers of tourists produce the following adverse effects: they carry in from the streets polluted dust and organic particles on their clothing and hair; their combined body heat raises the temperature by as much as 5°C; and they greatly increase the relative humidity of the air. The moisture and carbon dioxide given off by tourists combines to produce carbonic acid which dissolves the calcium carbonate of the fresco. Water vapours convert sulphur particles into sulphuric acid which also dissolves fresco. The body heat creates convective air currents which carry polluted particles up to the walls and ceilings. Water vapour can activate the traces of salt and detergent left behind after the cleaning with AB57.”

In 1981 Colalucci had equated the glue/size paints with “extraneous chemical substances” without which “and with the science we have today” he hoped “the frescoes will remain in good condition for a very long time”. As mentioned, he offered an assurance that he had left “a very thin film of dirt touching the paint surface with its varying ‘patina’. This fine layer of dirt acts as a form of protection to the paint.” As also mentioned, we now know that whatever Colalucci might have left behind performed no such service, and that dirt on frescoes is no protection from further accumulations of corrosive dirt.

Promises, Promises

There have been many unfounded assurances. In 1987 Kathleen Weil Garris Brandt, Professor of Fine Arts, at New York University’s Institute of Fine Arts, and spokeswoman for the Vatican on the restoration of Michelangelo’s Sistine Chapel frescoes, assured readers in Apollo that, “The substances used for the cleaning…have been used successfully for over twenty years… their chemical action is known and stops once the process is finished…the cleaning chemicals do not actually come into contact with the fresco surface”. Just months before in the Summer 1987 Art News, Summer 1987, the Moras themselves had claimed no more than that placing the solvents in a cellulose gel helped to “reduce penetration into the fresco”. In the summer 1987 Art News, the assurances were becoming more specific. M. Kirby Talley Jr., an independent consultant in fine art, interiors and art conservation, wrote:

In order to prevent the condensation of moisture on the surface of the fresco, the Vatican has already embarked on an extensive programme to control the micro-climate of the Sistine Chapel. Professor Camuffo of the University of Padua spent a year making detailed measurements of relative humidity, temperature and air movement. A climate-control system based on his findings, which will prevent the movement of air above the windows as well as filter it, is now being developed by Carrier-Delchi. Electrical heating coils, ‘A sort of giant electrical blanket,’ as Persegati called it, will be placed under the roof above the ceiling, and will help to maintain a steady temperature during the winter. A dirt absorbing carpet has already been installed on the stairs down to the chapel and on part of the floor inside. Carrier-Delchi is considering a wind shower to remove dust particles from people’s clothing before they enter the chapel. Low heat lamps that can be adjusted to the amount of natural light entering through the windows will further reduce the temperature.”

Synthetic Resins – On or Off?

Talley Jr. reported that Colalucci had assured him that Michelangelo had used no secco paint on the lunettes, and that while the synthetic resin B 72 had been used to seal the walls of the lunettes it had not been used to that purpose on the ceiling. Even the official apologias for B 72 were more disturbing than reassuring: “Like all restoration materials it has its good and its bad points”, Talley said. Frommel was quoted as saying “According to the critics B 72 is something which may become opaque in the future. Are the critics right when they say we don’t know what it will do? They say tests should have been made and then a long period of time should have been allowed to elapse before proceeding. Paraloid can close the surface to respiration. It can close the pores, and if that were to happen it might change the interior life of the fresco.” To this Talley gave voice to B 72’s champions. According to the Moras “If you don’t use Paraloid, what do you use? Organic resins and inorganic fixatives such as lime water, ethysilicates and barium hydroxide all have serious drawbacks. Of the synthetic resins the acrylics are the best, and of the acrylics Paraloid is the least bad.” Was the least bad, good enough for Michelangelo – and better than his own secco painting which had for centuries protected the fresco surfaces from airborne pollutants?

On this question, the Vatican’s accounts prove unsatisfactory and shifting. All that can be said safely is that B 72 was abandoned and not replaced at some point between 1986 and 1991, at which latter date Colaucci claimed “There was no final application to protect or saturate the painting”. This change of mind was defended in 1991: “Our decision not to apply a protective material derived from the awareness that any new material which is not homogeneous with the original components of the fresco will undergo rapid degradation, causing, in the best of cases, aesthetic damage.” This being so, we must expect some parts of the frescoes to deteriorate more rapidly than others – but how many? In 1991 Colaucci put B 72 applications at “lunettes 50 per cent, ceiling 3 per cent”. In 1993 (“Art Restoration” p. 120) we had noted that while protection of the frescoes was to depend on the thin layer of original dirt that Colalucci claimed to have left in place and on the above described plans to stabilise and purify the chapel’s microclimate: “When Michael Daley asked if the air-conditioning system would eliminate the great fluctuations triggered by tourists, he [Mancinelli] replied ‘No. It will reduce the peaks and the troughs but will not eliminate the problem entirely.’” Of course, at that date, as today, the problems could have been halved by halving the numbers of tourists. Then, as perhaps still is the case, on days when the Chapel was closed to visitors, visitor numbers to the Vatican museums fell by 60 per cent.

The Breach of Methodological Good Practice that Menaced Michelangelo’s Shading

In the execution of the cleaning, certain procedural lapses compounded the risks and dangers. Early in the programme (in 1981 when working on the lunettes), Colalucci had said that AB 57: “was created mainly for marble but the Moras experimented with it on fresco. It is like paste. It can be on for a minute or ten minutes. The effect varies with the amount of time it spends in contact with a surface. The danger is that if you leave it on a minute or two too long it will go beyond the foreign substances and start removing the paint. You can see little areas where I’ve applied AB57 in two or three stages. Each time I take it off well before it’s too late. Then I look at it and gauge how much more time it will need…Here’s a tiny patch where I left it on too long. In this little experimental patch you see completely solid violet paint, but around it you can see the gradations of dark and light, which are the shadings of Michelangelo’s own work.”

Why, then, were the varying thicknesses of the (mis-designated) “foreign and extraneous substances” all given identical applications of two three minutes-long applications set twenty-four hours apart? Such an uniform treatment of so vast and varying a programme of painting seemed to breach conservation’s own ethics and “good practice”. As we had reported in “Art Restoration”:

Within four years, Colalucci had abandoned this control of the solvent by constant observation and timing. In its place a standardized procedure was adopted, described in the 1986 ‘General Report on the Lunettes’: ‘First application, three minutes followed by removal and washing with water. Left to dry for 24 hours. Second application, three minutes followed by washing and leaving to dry as before’. These three-minute applications were said to have been ‘rigorously measured’. Colalucci explained the reason for the change of procedure: the size of the ceiling required that work be carried out by a team. Individual restorers, responding to the evidence of their own eyes, would draw different conclusions. Therefore, in order to obtain a ‘homogeneity of result’ – a ‘primary objective’ – they must be denied the opportunity to judge for themselves how long the solvent should remain in place. Solvent applications had to be predetermined, Colalucci felt, in order to avoid ‘either emotional involvement or complex mechanical manipulation on the part of the restorers’. When asked in 1985 at the Wethersfield Conference in New York why he did not adjust the timing to what his eyes were witnessing, he replied: ‘Because emotional or subjective conditions must not be permitted to intrude upon science.’ The scaffold, he added, did not permit stepping back to assess effects and the continuous bright lights of the Japanese film-makers ‘fatigued one’s eyes’. The activity of the film crews was itself a distraction as was also his having to entertain up to sixteen VIP visitors a day…” See Figs. 34 and 35.

Conservation Ethics and Showbiz Restorations

The inventors of AB57 held that cleaning should never be considered “entirely a technical matter…confined merely to the choice of solvent”. The restorer’s responsibility for the control of the solvent’s actions is absolute and should never be left to “depend on the natural uncontrolled action of the products” and must always depend on “the precise wish and aim of the restorer guided by his critical interpretation”. By failing to exercise control at all times, the restorer “deprives himself of the principal alarm signal when faced with new situations; he gives up looking ahead and allows the problem to resolve itself mechanically so that subsequently he can impose the result as an accomplished fact.”

By test-driving a new cleaning agent under television studio conditions in a constricted, over-crowded and art-politically febrile space, the Vatican restorers pioneered a new professional genre: conservation as both entertainment and professional swank. The combination of the Nippon Television Corporation sponsored showbiz and a provocatively radical restoration drew many protests. This spawned intensely propagandistic promotional razzmatazz, the unprecedented scale and character of which will be examined in Part III.

“The activity of restoration can be defined in terms of two overlapping headings, procedure and method. Procedure is fixed and invariable, and consists in the scientific planning and execution of the restoration project, regardless of the material involved. Method, however, is the department strictly of the action taken in the course of the restoration, and is therefore variable, subject to factors arising from the material, technique and state of conservation of the monument involved. “The adoption of a procedure which governs the progress of the work is characteristic of modern restoration. Under the impetus of a marked development in technological expertise, modern restoration has extended its established and primary function of conservation for aesthetic ends to include a research capacity, directed towards the work of art considered as an inseparable duality, conceptual and material. “In the past restoration practice aimed at cancelling out the effects of time and events upon the work of art, termed by Brandi comprehensively its historical aspect, absolute priority was given to its aesthetic aspect, conditioned of course by its contingent situation. The restoration of works of art was therefore entrusted to artists, who were free to introduce personal methods, often secret or private, consistent with the aim of returning the work to its pristine material state, but not necessarily to its original intended state. “In the evolution of the ‘art’ of restoration, the laboratory for the Restoration of Pictures in the Vatican Museums has had a not insignificant role. Founded in 1992 by Biagio Biagetti according to the latest ideas, and subsequently provided with a Laboratory for Scientific Research, the institute is today directed by by Carlo Pietrangeli who in 1978 established its guidlines in Rules for the restoration of works of art. “In June 1980 this laboratory, constitutionally responsible for the restoration of the pictorial patrimony of the Holy See, qualified and informed by its enormous experience, which goes back more than 50 years and has been constantly renewed both technically and in terms of personnel, undertook the most important task it had yet undertaken in its history, the restoration of the frescoes of Michelangelo in the Sistine Chapel…” ~ Gianluigi Colalucci, “Michelangelo’s Colours Rediscovered”, “The Sistine Chapel – Michelangelo Rediscovered”, London, 1986.

The restoration of Michelangelo’s frescoes in the Sistine Chapel was a venture that shook the very foundations of the art world more than any other single event has managed to do in the last quarter of a century. “Promoted and conducted with rigorously conservative objectives, over the course of its execution the restoration program assumed an ever-growing significance in historical and critical terms – an importance that was foretold when the first patches were cleaned and was fully confirmed by the restoration of the Eleazar-Mathan lunette.” ~ Gianluigi Colalucci, “Michelangelo The Vatican Frescoes”, by Pierluigi de Vecchi and Gianluigi Colalucci, 1996.

…The intuition that the colours must have been quite different from those that could be seen can be found sporadically in the writings of the more perceptive scholars of Michelangelo, from [Charles Heath] Wilson to Biagetti and Wilde. But clear and conclusive evidence of the original colours was established for the first time in recent times by the extraordinary photographs of the Japanese photographer Takashi Okamura, taken just before the restoration and published in a book of 1980, unfortunately in a small limited edition and now not widely seen. The eye of the camera, in itself much more acute than the human eye, and aided by much stronger light than is usually available in the Chapel, revealed beneath the dirt and deteriorated glue-varnish the tangible existence of of what the restoration today is gradually retrieving. “Although the book with Okamura’s photographs and the restoration that is now proceeding came about independently and for different reasons, the two are complementary, and Okamura’s book is today a valuable record of what for centuries had masked the true nature of Michelangelo’s painting; if the cleaning had not gone ahead, it would have been the sole means by which to achieve a proper or effective analysis of his work…” ~ Fabrizio Mancinelli, “Michelangelo at Work”, “The Sistine Chapel Michelangelo rediscovered”, London, 1986.

Above, Fig. 2: Michelangelo’s Moses.
Evaluating restorations (or attributions) requires a clear appreciation of an artist’s most secure works and characteristics. Michelangelo’s phenomenally potent carved figures, such as his Moses (above), found parallel realisation in the figures he was compelled to paint on the Sistine Chapel ceiling, such as the Libyan Sibyl shown at Fig. 1 and below. In the reproduction of his Moses at Fig. 2, we see how (natural or artificial) light and shadows are trapped/made by the architectural projections. Within the constraining rectilinear spaces set by the architecture, the figure’s own component parts move and shift against one another so as to produce planar and volumetric dynamism and expressive anatomical torsion.
MICHELANGELO’S USE OF DRAPERY
The not-naturalistic drapery in the Moses complements and enhances the body’s deportment with its own autonomously animated structures and vitalising rhythms. The deeply undercut, shadow-producing drapery over Moses’s left thigh had found direct pictorial anticipations on the ceiling in the Libyan and Erythraean sibyls shown here. Michelangelo had discovered, as Leonardo had taunted, that a painter controls his own lighting and can (like an etcher) submit it to his own singular will, darkening here, highlighting there, shaping and moulding matter with form-describing tonal values and relationships. In Fig. 1, which is a fragment of a coloured painting reproduced in greyscale, we “see” a piece of sculpture – or strictly speaking, a sculpturally conceived figure that happens not have been made but was depicted pictorially with an imagined optimal lighting so as to render its forms with the fullest sculptural lucidity and force. Such was Michelangelo’s genius in these matters that the fragment from his Libyan Sybil might be thought the creative equal of a fragment of the Parthenon’s carved frieze.
SPOT THE ODD ONE OUT:
Above, Figs. 3, 4 and 5.
Fig. 3 (above, top) is a fragment of the Libyan Sibyl’s drapery before restoration. Fig. 4 (above, middle) is the same fragment after restoration. Fig. 5 (above) is a fragment of an engraved copy of the Libyan Sibyl made in 1797 by a fine (Flaxmanesque) engraver, Tommaso Piroli.
Of the three images, the first is by Michelangelo as found before the last restoration. The second is the same fragment of the figure as it emerged after the last restoration. The third is the corresponding fragment of a copy showing the figure as it had survived for nearly three hundred years. We hold that the differences between the first and the second states constitute evidence of injury, and claim support for this reading in the third image here and in the images at Figs. 6, 7 and 8. As further corroboration, we show below how, in the wake of the restorations of the 1980s and 1990s, many similarly injured passages can be found throughout the ceiling. The painting contained in the first image (at Fig. 3) had never been challenged or doubted as part of an entirely autograph work of Michelangelo. Never challenged, that is, until the beginning of the last restoration when the Vatican’s restorers advanced a claim that this figure, and all others on the ceiling, had been so deformed by dirt and successive layers of restorers’ varnishes as to constitute a corrupted and misleading Michelangelo. The true Michelangelo, it was contended, lay unrecognisably different under alien material accretions which, with the help of some very powerful chemicals-in-a-gel, would be dispersed – even though the resulting change of appearance in the paintings would in turn require that everything previously thought about the artist be overturned. Tragically, the Vatican authorities permitted this hubristic, artistically perverse and historically unsupported programme to proceed. That which had survived for nearly five hundred years in Fig. 1, was turned after two three minutes long chemical dousings into Fig. 2.
THE CHANGED CHARACTER OF THE DRAPERY
The pre-restored image showed drapery that was boldy massed, purposefully shaded and satisfyingly sculptural in its volumetric descriptions and compositional fluency. To educated eyes, its then appearance could only have been a product of artistry. It could not have been an accidental by-product of random accumulations of unequally disfigured accretions, as has been claimed in defence of all the restoration changes. The pre-restoration state, as is shown above, bore too close a family relation to Michelangelo’s carved sculptural forms for its authorship ever to have been in question. By comparison, the post-restoration image is weaker; its forms smaller; its tones consistently lighter. The surviving tonal modelling is more local to each piece of material, less broadly unified across incidents. It is thus weakening to the previously strong overall sculptural effects, spatially ambiguous, and more akin to shallow relief than free-standing sculpture. There is no historical corroboration for today’s appearance – it appears in no copies. All of which raises the question: “Why was the very design of Michelangelo’s work changed by this removal of a piece of drapery?”.
THE LOST SECTION OF DRAPERY
The large fold of drapery that hangs from the lower left leg no longer sweeps down gracefully from below the knee, as seen if Figs. 3 and 5, but emerges abruptly and uncomfortably at the shin. On stylistic grounds alone, the removed material cannot be said to have been an addition made by some other person, let alone by accretions. This section of pre-restoration drapery was entirely, seamlessly of a piece, and served a clear compositional purpose.
Above, Fig. 6. The Libyan Sibyl, as copied in 1797 by Tommaso Piroli. As well as giving the clearest account of the not-yet truncated drapery hanging from the left leg, Piroli (an engraver of antiquities) provides an elegant shorthand account of Michelangelo’s three principal zones of dark tone. The first, at the bottom between the legs, differentiates their positions in space vis-a-vis the viewer: the side of the more distant leg misses the strong light source (as indicated by its emphatically cast shadow) and is therefore optically subordinated by darkened tones. The arms and torso are relieved by dark tone over the drapery hanging from the table. The curving sweep of drapery on the right begins brightly at the top, as if caught by the light. This area of brightness relieves the darker shaded side of the arms and torso. It then darkens as it passes close to the Sibyl’s body before lightening again as it moves froward into the light that catches the left leg and foot.
Above, Figs 7 and 8: Two states of an anonymous 16th-century engraving.
Although the author of this copy (published in “La Sistina Riprododotta”, 1991, and here reversed) was not as fluent a draughtsman as Piroli, and took liberties with the architecture, on the two crucial issues of the right foot’s cast shadow and the shape and the extent of the hanging drapery at the raised left leg, the copy is entirely consistent with the later artist’s testimony. Thus, just as with Piroli two centuries later, we see that the drapery emerged below the knee and at an acute angle. It did not, as today, burst into view abruptly at a right angle from behind the shin, as left by the restorers. We can rule out the possibility that a change might have been made to Michelangelo’s drapery by a restorer even before this 16th-century engraving was made. The restorer known to have been called in during the 16th-century – Domenico Carnevale – did so in 1566. He made five repairs in total and all were made in buon fresco, not a secco. He did no work on the Libyan Sibyl. Thus, only Michelangelo could have amended his own buon fresco work on the Libyan Sibyl’s drapery with a secco painting – just as he can be seen to have done on the sybil’s right foot…which can also be seen to have been injured in the last restoration, at Figs. 11, 12 and 13.
Above, Figs. 9 and 10. The legs of the Libyan Sibyl, as published in 1990 (left) and in the post-restoration state in 1992 (right). In Fig. 9 we see how before restoration the former design of the hanging drapery helped create a compositionally mediating, “fanning” movement between the position of the two legs, as had been recorded in the 16th and 18th-century copies shown above. Both copies show that, as before restoration, the wedge-shaped piece of hanging drapery ran into the shadowed zone that served to push back the right leg and give greater prominence the left leg.
THE MANGLED FOOT AND ITS DISAPPEARED SHADOW
Above, Figs. 11, 12 and 13.

This sequence records many alterations made in the Libyan Sybil’s right foot: before cleaning (top); after cleaning (middle); and after repainting (bottom). In fig. 11 we see a mini fanning movement in the three short dark accented folds at the ankle of the sybil’s right foot which have melted away in Fig. 12. We see also in Fig. 11 examples of what Alexander Eliot described as “Michelangelo’s loving depiction of fingernails, eyelids and tiny wrinkles”. Once again, Michelangelo’s habit of placing a dark shadow beind the lit edge of a form and a light ground behind its shaded side was evident here in his treatment of the strategically dramatic arched foot.
UNDOING AND (PARTIAL) REDOING

This sequence also comprises a tacit acknowlegement of error on the part of the restorers. Evidence is here present not just of the loss of the foot’s cast shadow (as also with the Jonah below) but even of its anatomical credibility. Michelangelo had repositioned this foot, scraping away one part and adding another. The cleaning undid this revision, and thereby produced (uniquely in Michelangelo’s oeuvre) a human heel that was not rounded but that came to a point, as in Fig. 12. We questioned this transformation (and that of the Erythraean Sibyl’s right foot, shown below) to Fabrizio Mancinelli, the co-director of the restoration, when he gave a talk on the restoration at the Courtauld Institute, London. Later, on visiting the Chapel we discovered that the heel had become rounded again if not entirely whole, as seen at Fig. 13. Clearly, if the repainted addition is now correct, it should never have been removed in the first place.

Above, Fig. 14: An article in The Independent of 22 November 1991, which first showed the Erythraean Sibyl’s right foot as it emerged after restoration.
Above, Figs. 15 and 16: The Erythraean Sibyl’s right foot before cleaning (left) and after cleaning and restoration (right). Note, in addition to the mangled foot, the changes made to the forms and the colours of the drapery. We assume that no one believes that the foot today is as Michelangelo intended it to be left. We have found deafening the collective silence of art historians and art critics on this grotesque blunder. Perhaps some think that such sacrifices of authentic painting are a price worth paying to get at brighter colours?
Above, Fig. 17: The Libyan Sibyl and the Prophet Daniel, before restoration
Note how effectively Michelangelo had simulated monumental figures set within palpable architecturally bounded spaces. On the left, we see the Libyan Sibyl (discussed further below) and the Prophet Daniel. Note particularly with what force the drapery over Daniel’s right shoulder cascades and twists, and how emphatically it captures a deep dark shadow next to his right side.
Above, Figs. 18 and 19: The Prophet Daniel, before restoration (left) and after restoration (right).
In this pairing, we see one of most massive destructions of a Michelangelo a secco revision. Once again, corroboration of the pre-restoration state – and disqualification of the post-restoration state – is found in early copies of the figure, as shown below.
Above, Figs. 20 and 21. Engraved copies of the Prophet Daniel.
These two copies made in the 1790s by artists working in very different graphic styles (in tones in the case of Giovanni Volpato, left, and with lines with Tommaso Piroli, right) both testify to the then survival of Michelangelo’s unprecedented pictorial chiaroscuro – his emphatic placement of lights against darks which had so struck and thrilled his contemporaries.
When we first reminded the restoration’s supporters of Michelangelo’s original pictorial schema and drew attention to the corroborating copies, Nicholas Penny, for one, rushed to be dismissive, saying of the copies that “none of them support the claim Daley makes”, and added, “I am surprised to hear that the ceiling was ‘praised precisely for its unprecedented chiaroscuro’.” In the 11 February 1993 London Review of Books Dr Penny had recited the then Standard Defence For The Restoration:
Study of the ceiling now that it has been cleaned tends to distance Michelangelo from the art of recent centuries – and from the work of artists who were inspired by the ceiling – and reveal a far closer connection with the dazzling colours favoured by artists in his immediate following and also evident in some of the better preserved 15th-century panel paintings.”
The operative words were “now that it has been cleaned”. While it is true that Michelangelo’s biographers had suffered the handicap of having to respond to the ceiling when it was freshly painted and not yet “cleaned”, it was remiss of Penny not to have noticed that none of Michelangelo’s contemporaries had spoken of dazzling colours or likened his great fresco cycle to 15th-century panel paintings. The truth is that Michelangelo had shown his figures and his fictive architecture as if placed in a brilliant “cinematographer’s” light – why else, how else, could so many of his feet have originally sported such dramatically cast shadows on the ceiling’s illusionistic mini projected “floors”, and so many of his figures have cast such dramatic shadows onto the walls?
EVEN GOD WAS AT RISK FROM THE CLEANERS
Above, Figs. 22 and 23: God (detail) in Michelangelo’s panel showing the bestowing of life upon Adam, before cleaning (top), after cleaning (above).
If old pictures were simply being cleaned and not injured, their ranges of tonal values would be extended and not diminished, as seen here. For example, in the bottom left-hand corner what was graduated, nuanced, modelled, has become uniform, flatter, more “on the surface”. The ridges of drapery which formerly wrapped round the shoulder, now break off short. The folds themselves have become simpler in drawing, less expressive in shading. Lines of under-drawing emerge more strongly, while crisp tonal demarcations blur. Individual hairs get lost. If Michelangelo really had left his painting as in this “cleaned” state, what might have improved the drawing and modelling to the degree seen in the uncleaned state through all the (alleged) foreign accretions and filth?
Above, Fig. 24. This pre-restoration photograph shows the crucial junction between the Last Judgement and the ceiling. The zone contains some of Michelangelo’s most brilliant figural inventions, of which the commanding central Jonah earned the greatest admiration when the ceiling was unveiled. Note the general dispositions of tonality, the relative lightness of the illusionistic compartmentalising architectural elements, and the then legibility of the shadow cast by Jonah’s left foot – which foot, curiously, touches the same architectural arch as the foot of the Libyan Sibyl, above and to the right of Jonah.
Above, Fig. 25: Jonah’s left foot, before cleaning (left), and after cleaning (right).
While no one enthused over Michelangelo’s colours, everyone marvelled at his unprecedented use of light and shade on the ceiling. Among them, Condivi thought the Jonah the “most admirable of all…because contrary to the curve of the vault and owing to the play of light and shadow, the torso which is foreshortened backward is in the part nearest the eye, and the legs which project forward are in the part which is farthest.” Vasari asked: “Then who is not filled with admiration and amazement at the awesome sight of Jonah…The vaulting naturally springs forward, following the curve of the masonry; but through the force of art it is apparently straightened out by the figure of Jonah, which bends in the opposite direction; and vanquished by the art of design, with its lights and its shades, the ceiling even appears to recede.” [Emphases added.] Note carefully what was being said at the time: by his drawing and his use of lights and darks, Michelangelo had made surfaces which were actually advancing towards the viewer seem to recede. What was not said, pace Mancinelli, was that Michelangelo’s colours had been used “pure” and that, as such, they had played “a primary structural role”. No authority then existed for the restorers’ recent trading of those impeccably accredited lights and darks for today’s heightened colours.
Above, Fig. 26. Four copies of Jonah, as published in “Art Restoration: The Culture, the Business and the Scandal” in 1993.
Most certainly, no authority existed for removing the shadow cast by Jonah’s foot. Countless copies over the centuries had recorded it. Giulio Clovio, in his copy shown here in the top left-hand corner, also recorded (in the bottom corners) parts of two lunettes that Michelangelo had painted before 1512 but destroyed before 1536 to prepare a continuous surface for the Last Judgement.
Above, Fig. 27: A 19th century engraved copy of a now lost drawn record of the two sacrificed lunettes. The copy of a copy of the sacrificed lunettes shows precisely “the kind of suggestive painting by shadows for which Michelangelo was admired until a few years ago”. Its testimony specifically contradicts the restorers’ claim that the suggestive painting was “essentially the product of candle smoke and still more of glue varnishes applied possibly even before the 18th century.” The dramatic shading in this record captures the decisively drawn shadow at Jonah’s left foot, as glimpsed at the top left. Fabrizio Mancinelli’s claim that the lunettes had erroneously “been interpreted for centuries by scholars as chiaroscuri with light and shade distributed so that the figures seem to be emerging from the darkness”, flouted Paolo Giovio’s 1525 testimony that Michelangelo had “used a gradually diminishing light to suggest some figures in the distance, almost hidden…”
Above, Fig. 28: A lunette figure before (left) and after (right) restoration. This was one of three photo-comparisons of the cleaned lunettes published by the sculptor Venanzo Crocetti in the December 1989 Oggi e Domani. That there was much surface disfigurement on the lunettes is not in dispute. Crocetti had seen for himself after years on the scaffolds that the effects of smoke varied by location within the Chapel and that the lunettes had been disproportionately affected because of their position at the junctions between the walls and ceiling. The central question in the restoration generally, as here, is why previously evident artistic features (shadows, folds of drapery and so forth) disappeared along with the dirt through which they had formerly been visible? How, for example, could the left thigh of this figure have been perceived before restoration with a light upper surface and a darker side surface – and why did that tonal distinction disappear?
Above, Fig. 29: An engraved copy of Michelangelo’s Erythraean Sibyl made in the 1570s by Giorgio Ghisi. Here we see that shadows that disappeared in the last cleaning had been recorded within sixty years of the painting and therefore could not have been products of later accretions. It has sometimes been suggested that the testimony of engraved copies is not reliable because engravers exagerated tonal effects. Ghisi produced five other major plates of the prophets and sibyls (and of their surrounding figures). Like his Erythraean Sybil above, all showed a strongly dramatic use of shading that was still to be found in the figures themselves until the restoration. If Ghisi had exaggerated, what had he been exaggerating at a time when soot and restorers’ alleged varnishes had yet to impart their (Mancinelli-attributed) chiaroscuro-esque effects? Had Ghisi and other early copyists like Giulio Clovio collectively anticipated dramatic effects that Time and Accident would bestow centuries later?
Above, Fig. 30: The Erythraean Sibyl before cleaning. Note the many correspondences of lighting and shading between the engraving and the photograph four centuries later. In both, the Sybil’s head casts a shadow onto the architecture. In both, the face’s lit profile is thrown into relief by background shadow. In both, the deeply undercut ‘U’ shaped fold of drapery that runs from the right thigh begins in the light but sinks progressively into a shadow which merges with the shadow that the figure casts onto the architecture.
Above, Figs. 31 and 32. The head of the Erythraean Sibyl before cleaning (left), and after cleaning (right), showing catastrophic losses of modelling and shading. Note here the particulary emphatic and successful use of the tonal convention of relieving light contours against dark grounds, and vice versa, so as to deploy the most sculpturally expressive range of half-tones in between.
Above, Fig. 33: This (rotated) view of the ceiling in which the vertical wall appears in the bottom left corner shows the complicated curved geometries on which Michelangelo’s images were painted and the curious way in which the shadow-casting feet of Jonah and the Libyan Sibyl touch the same piece of curving architectural moulding.
Michelangelo’s task in designing and executing such a complex array of figures in so precise an “architectural” context was immensely difficult. In this respect, it would be less than human not to feel some sympathy for the restorers whose handicaps were compounded by the decision to allow the sponsors (the Nippon Television Corporation) to film the entire operation from the scaffold. In addition to the TV crews, other photography was permitted as part of the restoration’s promotion in the media. In one specialised respect, photographs that catch restorers at work can illuminate restoration proceedures to a degree rarely encountered in offical presentations.
Above, Fig. 34: The Libyan Sibyl during cleaning. This photograph, of a restorer being filmed at close quarters while working on the Libyan Sibyl, was reproduced across two pages of a 1992 book “Michelangelo and the Creation of the Sistine Chapel” by Robin Richmond, a painter who was supportive of the restoration. It shows that the figures were being cleaned first and separately from the backgrounds. A slight overlapping of the cleaning onto the figures’ dark green “relieving” background has introduced a light green halo-effect. The difference between the light green ‘halo’ and the adjacent dark green between the figures indicates the magnitude of the reductions of tonal values that took place in the shaded zones throughout the cleaning. As Crocetti had observed, Michelangelo had used his size or glue painting most of all in these zones. Wilson, testified that he had done so with a finely ground black pigment.
Above, Fig. 35: The Libyan Sibyl during cleaning. Over the years, many excellent photographic records of major restorations have appeared in National Geographic. The December 1989 issue carried an article (“A Renaissance for Michelangelo”) which contained the stunning photograph above by Adam Woolfit (here in greyscale for comparative purposes). This photograph records the cleaning as it approached the draperies over the Libyan Sibyl’s legs. The halo effect seen at Fig. 25 had by then disappeared along with the removal of almost all of the dark green background toning. Only a small rectangle of the former dark paint on the background remained, temporarily attached to the bottom of the Sibyl’s left upper arm. Woolfit eloquently captures the extremely bright artificial television lighting under which the restorers worked, and, most valuably of all, an “in-between” state when the incoherences that emerge in the stripping-down of paintings have yet to receive restorers’ tidying and patching-up with the paint brush (-or, in restoration trade posh, “reintegration”) .
Above, Fig. 36: The Libyan Sibyl as published in 1990.
Above, Fig. 37: The Libyan Sibyl as published in 2010. The transformation during restoration was immense. In 1986 Mancinelli claimed that Michelangelo had used his colours “constantly pure” and that they had served “a primary structural role” enabling him to “abandon almost altogether traditional chiaroscuri modelling”. The following photographs chronicle the swift demise of Michelangelo’s nearly five hundred years old chiaroscuri.
Above (top), Fig. 38, the torso of the Libyan Sibyl, as published in 1904 and, Fig. 39, in 1996. Within the characteristically restoration-compressed range of tones, the boy’s hair, which previously was light and blonde, relieved against a blackish green ground (as seen in Figs. 36 and 38), is now darker than the radically “cleaned” light green background drapery. If we consider the whole figure before cleaning (as at Figs. 17, 33 and 36) we see a consistent and dramatic light falling on it from the left. As well as casting the strong shadow from the right foot, that light illuminated the left side of the sibyl and the right-hand side of the architecture. The sibyl’s head had a lit side and shadowed side and, just like that of the Erythraean Sybil, each side was set off by a tonally contrasted background. Similarly, the brightly lit left arm was strongly relieved by the very dark green drapery, while the shaded right arm was thrown into relief against the light stonework…and so forth. After a cleaning, we would expect Fig. 39 to be like Fig. 38 in its values only more so with lighter lights and darker darks. Instead, while Fig. 39 is now certainly cleaner looking and tidier, by comparison with its former self, it resembles an early state of an etching before the dark tones and blacks have been worked up – rather as may be seen at Figs. 7 and 8.
Above, Fig. 40. The Libyan Sibyl’s head, as published in 1966, before restoration. Note the progressions of tones, and the brilliant highlight at the shoulder.
Above, Fig. 41: The testimony of Woolfit’s 1989 photograph (detail) of the cleaning in progress. We see at this stage of restoration that along with the removal of the glue-based paint on the background green draperies, the formerly clear and precisely established contours of the left upper arm have been disrupted by the emergence of dark patches of sketchy, inconsistent and disconnected outlining. Given that these arbitrary irregularities are not present in either the pre- or the post-cleaning states, we must consider how they arrived and how they were persuaded to depart.
Above, (top) Fig. 42, the Sibyl’s forearm, as seen in 1904. Above, (middle) Fig. 43, the Sibyl’s forearm, as seen during cleaning in 1989. Above, Fig. 44, the Sibyl’s forearm as seen after cleaning and repainting. At Fig. 43, once again, along with the removal of the former dark toning material behind the arm, we see remarkable changes to the tonal modelling of the arm itself and to its previously lucid, now erratic contours. We would claim that such changes cannot be seen as anything other than restoration-induced injuries: 1) It is inconceivable that Michelangelo would ever have been content to leave a limb in such a condition. (Think of the Virgin’s arms in the Doni Tondo.) The massively intrusive overdrawing of the thick bar-like contour of the thumb and forefinger seen after cleaning at Fig. 43 is inexplicable except as preliminary underpainting. (Remember that Crocetti complained of AB 57 having penetrated the frescoes to a depth of half centimetre.) 2) It is inconceivable that Michelangelo would have depicted the left contour of the forearm being ruptured by the intrusion of the edge of the giant book’s cover board that rests on the top of the draped table behind the sibyl, as seen at Fig. 43 (and as such, exclusively by courtesy of Woolfit’s photograph, so far as we know). Such an illogical intersecting relationship might have appealed to Picasso in his analytical cubist phase, but it could hardly have done so to Michelangelo. How, then, did it arise and how did it disappear? Have any accounts been published of the emergence and swift extinguishing of this extraordinary pictorial phenomenon? Has film of the cleaning of this arm been broadcast? 3) Finally, it is of course, inconceivable that had Michelangelo left the forearm drawn and modelled as seen in 1989 at Fig. 43, that subsequent accumulations of soot and glues could have sufficiently remedied his defects of drawing so as to bring the work to the condition seen in 1904 at Fig. 42. Clearly, the restorers themselves did not accept the emerging injuries to the arm to be a fair recovery of some original and authentic condition, because it is apparent from Fig. 44 that steps were taken to paint out some of the more glaringly incongrous defects. But who was the author of the “corrections” to the very defects that the restoration unleashed? Who should be accredited for authorship of the hybrid, revised arm as seen at Fig. 44?
Above, Fig. 45. In December 1989 National Geographic published this beautifully balanced record (here flipped) by Victor R. Boswell, Jr. of the last moments of the Sistine Chapel ceiling as finished by Michelangelo. Springing from the centre top of the not-yet-cleaned Last Judgement we see Jonah around whom congregate, in the last section of the ceiling that Michelangelo painted, some of the artist’s most miraculously inventive figures set in their fictive temple-in-the-sky. For a little longer this section retained the majesty and mystery of the infinite space and dark depths that had survived for nearly half a millennium.

The Sistine Chapel Restorations: Part I ~ Setting the Scene, Packing Them In

21 January 2013

The Vatican authorities are in conservation crisis today because they stripped the Sistine Chapel frescoes bare in the 1980s and 1990s. They did so against material and historical evidence that Michelangelo had finished off his frescoes with additional glue or size-based a secco painting (see right and our posts of 1 April 2011 and 12 November 2012). That original, autograph material was removed in full knowledge that the stripped-down bare fresco surfaces would thereafter be attacked by atmospheric pollution unless given some other protective covering (see Appendix below). An attempt to coat the frescoes with synthetic resin (Paraloid B72) was abandoned leaving some surfaces clogged and the rest unprotected. The authorities then promised to install hi-tech paraphernalia that would somehow prevent the polluting atmosphere from making contact with the Chapel’s painted walls and ceiling (see caption at Fig. 4). As was shown in our previous post, that cockamamie promise was not delivered. Today, in a chapel increasingly over-crowded with paying visitors (see Fig. 1), these stripped-down frescoes stand in greater peril than ever.

Ironically, the “cleaning” of the ceiling, which arguably constitutes the greatest single restoration calamity of the 20th century, occurred at a time when picture restorers had skilfully rebranded themselves as safe, scientifically validated “conservators” of all that is valuable – even though Kenneth Clark had recently admitted to having founded the National Gallery’s science department in the late 1930s in order to dupe the public and wrong-foot restoration critics. A grandly titled “Laboratory for Scientific Research” had been created at the Vatican in 1922 on the “latest ideas” but during the 1980s Italian restorers admitted that running technical “tests” before restorations was professional “window-dressing” because it was always known in advance which materials were to be used.

Some restorers sincerely believed in the scientific hocus pocus that supposedly had trumped anachronistic and unacceptably “subjective” aesthetic responses. The appointed chief restorer of Michelangelo’s frescoes, Gianluigi Colalucci, was one such, insisting that: “Emotional and subjective considerations must not be permitted to intrude upon science”. At that time the Vatican’s curatorial and administrative authorities may not have sufficiently appreciated the extent to which every restoration of a great work of art is an accident waiting to happen: a collision of sublimity and incomprehension made tangible. In 1993, at the beginning of the fourth chapter of the JamesBeck/Michael Daley book “Art Restoration: The Culture, the Business and the Scandal”, we asked:

If authentic painting by Michelangelo has been lost in the course of a scientific restoration, many questions need to be answered. Did a blunder occur because of or in spite of the use of a scientific approach? Has too great a dependence on scientific data undermined crucial powers of aesthetic discernment and judgement? Is the scientific method of restorers rigorous or slipshod? Is the scientific status of modern conservation legitimate or bogus? Do restorers always follow their own ground rules?”

In the last twenty years it has become clearer that the claimed scientific underpinnings of picture restoration methods were spurious and that an appreciation of the workings of art and its internal relationships is not to be gained through some analysis of material components in a laboratory, however highfalutin and expensive the “investigative” or “diagnostic” apparatus may be. Beyond its conceptually simplistic and aesthetically impoverished terms of reference, the very reporting of “scientific” conservation methods has lacked both critical rigour and methodological consistency. In practice conservation science has provided a flag of convenience under which fundamental artistic questions can be evaded while ever-more ambitiously grandiose, lavishly funded and spectacularly transforming projects are launched. The authorities at the Vatican seemed quite oblivious of the ease with which even the most modest restorations can escalate into dangerous and irreversible treatments.

In 1964 Dr Deoclecio Redig de Campos, the Vatican museums’ curator and director of restorations, launched a cautious cleaning of the 15th century frescoes by Perugino, Botticelli, Ghirlandio, Rosselli and Signoreli on the lower parts of the Sistine Chapel’s north and south walls. After 15 years, that programme led to the cleaning of two minor 16th century frescoes by Matteo da Lecce and van den Broecke on the east wall. By that date, direction had passed to Dr Fabrizio Mancinelli, the new curator (and soon to be, with Colalucci, the co-director of the Nippon Television Corporation-sponsored restoration of all of Michelangelo’s Sistine Chapel frescoes). As we reported in “Art Restoration”, Mancinelli decided that “Redig de Campos’s cautious policy of removing only part of the layer of grime and foreign substances…was not appropriate in this situation.”

What Mancinelli deemed appropriate was that the minor frescoes should be cleaned with the new aggressive cleaning compound AB 57, even though this would obliterate original painting applied a secco by the artists onto their frescoes when dry. Curiously, Mancinelli’s justification for this removal of authentic and historical material was primarily aesthetic. That is, he held that a cautious cleaning and repairing of the damaged original secco paints would give only “disappointing results” compared with what might be attained by what he termed “a more radical cleaning”. We should be absolutely clear: “radical” was a euphemism for stripping the paintings down to their bare fresco surfaces in order to introduce heightened (but inauthentic) colours. Although the programme was to prove unethical by restorers’ own professional codes, Mancinelli persuaded the authorities that the visual “gains” to be had by trading original material for chemically brightened colours on those two minor works would outweigh even a directly consequential need to “return to the side walls and [do] a more thorough job there too.” (Just as the slowest ship determines the speed of a convoy, so in decorated chapels the most brightly scrubbed surface sets the overall level of cleaning. Michelangelo’s fate was sealed.)

While restoring the east wall works in 1979, a single test of AB57 was made on one of Michelangelo’s lunettes (see Fig. 8 and, for the consequences, Figs. 4-7). Professor Carlo Pietrangeli, the director of the Vatican Museums, said in 1982 “the results were so encouraging that it was decided to take on the whole ceiling. By the summer of 1980 the work had begun.” As Pietrangeli told Patricia Corbett in the May 1982 Connoisseur, once AB57 was shown to deliver chromatically transformed frescoes, “No one was able to resist the temptation”. In 1987 Dr Walter Persegati, the Vatican Museums secretary and treasurer, said in the Bible ReviewThese tests brought forward such colours that we were both scared and excited…It was decided that the procedure developed for the cleaning of the van den Broeck and Matteo da Lecce was applicable to Michelangelo’s frescoes. Therefore, we decided we had to do it.”

Note that because it had been decided that it could be done, it was “therefore” also decided that it should be done. In Part II we investigate the means, the methods and the artistic consequences of that novel application of a new cleaning agent to the very old, very precious decorated surfaces of the Sistine Chapel. In doing so we also show why the Vatican’s curators were right to be scared.

APPENDIX

“A major purpose of the conference was to underline a basic truth: the conservation of any work of art is doomed to failure unless equal emphasis is given to its past and its future vicissitudes…Scientists and historians worry that conservators can be too ready to intervene, too impatient of prior tests, and insufficiently heedful of future dangers.” ~ Kathleen Weil Garris Brandt, Professor of Fine Arts, at New York University’s Institute of Fine Arts, and spokeswoman for the Vatican on the restoration of Michelangelo’s Sistine Chapel frescoes, reporting the proceedings of the “London symposium on the conservation of wall-paintings” in the November 1987 Burlington Magazine.

“There is therefore much concern about the future of the frescoes, given that no protective layer has been applied in this campaign (the controversial use of paraloid was abandoned at an early stage of the cleaning of the lunettes). The Vatican has decided to seal the windows and introduce an air-conditioning and filtration system. Doubts were expressed at the conference. Could the threat from faulty air-conditioning be worse than the threat from atmospheric pollution and mass tourism? ” ~ Caroline Elam, editor of the Burlington Magazine, reviewing the 1990 symposium on the Sistine ceiling restoration held in Rome to give preliminary consideration to the cleaning of Michelangelo’s “Last Judgement”.

“A ‘drunken herd’ of ‘unruly’ tourists is damaging Michelangelo’s famous Sistine Chapel paintings, one of Italy’s leading arts figures claimed as the pope prepared to mark the 500th anniversary of the iconic frescoes’ creation. Some 5 million people visit the chapel every year – sometimes as many as 20,000 in a single day — and an increasing number of experts are now arguing that mass tourism is damaging the paintings. Despite a major, 14-year-long restoration project in the 1990s, they claim that the breath, sweat, dust and pollution brought in by visitors dramatically changes the Chapel’s humidity and temperature – factors to which frescoes are particularly sensitive…” ~ Claudio Lavanga, NBC News, 31 October 2012.

On 12 November 2012 Art Daily cited a disturbing Associated Press report on the Sistine Chapel:
“The Vatican Museums chief warned that dust and polluting agents brought into the Sistine Chapel by thousands of tourists every day risk one day endangering its priceless artworks. Antonio Paolucci told the newspaper La Repubblica in comments published Thursday that in order to preserve Michelangelo’s Last Judgment and the other treasures in the Sistine Chapel, new tools to control temperature and humidity must be studied and implemented. Between 15,000 and 20,000 people a day, or over 4 million a year, visit the chapel where popes get elected, to admire its frescoes, floor mosaics and paintings. ‘In this chapel people often invoke the Holy Spirit. But the people who fill this room every day aren’t pure spirits,’ Paolucci told the newspaper. ‘Such a crowd … emanates sweat, breath, carbon dioxide, all sorts of dust,’ he said. ‘This deadly combination is moved around by winds and ends up on the walls, meaning on the artwork.’ Paolucci said better tools were necessary to avoid ‘serious damage’ to the chapel. Visitors who want to see Leonardo da Vinci’s ‘The Last Supper’ in Milan must go through a filtration system to help reduce the work’s exposure to dust and pollutants. This has made seeing da Vinci’s masterpiece more difficult: 25 visitors are admitted every 15 minutes. The Sistine Chapel, featuring works by Michelangelo, Botticelli and Perugino, underwent a massive restoration that ended in the late 1990s. The restoration was controversial because some critics said the refurbishing made the colors brighter than originally intended.”

“In an article in Corriere della Sera, Pietro Citati, a leading literary critic and biographer, has demanded that the Vatican limit access to the chapel, claiming it would save the frescoes from damage and restore some decorum to the consecrated site. Describing a visit, Citati claimed that ‘in the universal confusion, no one saw anything’ and ‘any form of contemplation was impossible’. The answer, he said, was to reduce the number of visitors drastically. ‘The church needs money for its various activities, but these monstrous conditions are not possible,’ said the writer, a close friend of the late novelist Italo Calvino. The manager of the Vatican museums, which include the chapel, fought back on Friday in the pages of the Holy See’s daily paper, L’Osservatore Romano. ‘The days when only Russian grand dukes and English lords or [American art expert] Bernard Berenson could gain access to the great masterpieces are definitely over,’ wrote Antonio Paolucci. ‘We have entered the era of large-scale tourism, and millions want to enjoy our historical culture,’ he said. ‘Limiting numbers is unthinkable.’”

It derived markedly in its (uncritical) sentiments from from the Vatican Museums’ secretary/treasurer Walter Persegati: “We learned from Dr Persegati that the Vatican is installing an air system that will protect the cleaned ceiling by making sure that no contamination, human or other, reaches it. The system provides a warm cushion of air just below the frescoes that will be a barrier to keep the chapel’s slightly cooler air containing dirt and dust away from the paintings. This cooler air will circulate throughout the chapel, but just below the warmer cushion of air.”

His photo-comparison shows the figure before cleaning (left) and after cleaning (right) and therefore pinpoints the indefensible inversions of value that occurred, where what was once darker than becomes lighter than, and vice versa.

In the section on the volume’s illustrations, the brilliant Michelangelo scholar and Columbia University professor wrote: “Because of the war it was not possible to procure the same quality of ink for the reproductions as that used in the first volume, and therefore the chiaroscuro lost something of its softness.” Tolnay died in January 1981. Soon after, Fabrizio Mancinelli claimed that his cleaning had led to the “surprising conclusion that the kind of suggestive painting by shadows for which Michelangelo was admired until a few years ago was essentially the product of candle-smoke and still more of glue varnishes”. Mancinelli died some years ago and can therefore no longer defend himself, but his attributing of Michelangelo’s brilliant sculpturally informed chiaroscuro to the arbitrary centuries-long cumulative effects of smoke and glue, must stand as one of Scholarship’s loopier contentions.

Misreading Visual Evidence ~ No 2: Michelangelo’s Sistine Chapel Ceiling

April 1st 2011

No single proof of a restoration-induced injury to a work of art could be clearer than the photograph shown here (Fig. 1) of a section of Michelangelo’s Sistine Chapel ceiling frescoes. It was taken after the last restoration and shows in its centre section a repair made in 1566 by the painter Domenico Carnevale when a section of Michelangelo’s fresco fell away during settlement of the building (see Fig. 2 diagram). Carnevale had re-plastered the loss and, while the plaster surface was still wet, faithfully painted it to match Michelangelo’s (then) surrounding colours and tones. The repair was a good one and for centuries it remained almost invisible (see Figs. 4, 5 & 6). Ever since the last restoration it has been glaringly evident that Carnevale’s painted section no longer matches what has survived of Michelangelo’s painting (see Fig. 7). As will be shown, on the evidence of these photographs, fair estimation can be made of the injuries inflicted upon Michelangelo’s frescoes during restoration.

The reason why the photographs testify to restoration injury is simple and elegant. Carnevale’s repair was made a fresco in “good” or buon fresco, which is to say, solely with pigments that were painted onto the still-wet plaster and, crucially, without any later additional painting on the surface of the fresco after it had dried. With this method, Carnevale matched the pictorial values of Michelangelo’s frescoes as they were then found, only half of a century after their completion. However, unlike Carnevale’s painting, where the pigments were locked into the lime plaster when it dried, Michelangelo’s own frescoes were completed a secco – that is to say, with much additional glue or size-based painting applied to the surface of the frescoes after they had dried. Against great evidence (see below), the Vatican’s restorers concluded that Michelangelo had painted entirely in buon fresco without a secco additions and, on that (unsound) decision, they contended that it would be perfectly safe to apply a recently developed oven cleaner-like thixotropic cocktail of cleaning agents (in two applications of three minutes duration each, each being washed off with copious amounts of water) that had been designed to strip polluted encrustations from marble buildings and that would most certainly strip all organic material – which in the event would include Michelangelo’s own glue-based painting – from the ceiling’s plaster surface.

Because Carnevale’s own painted repair was not so vulnerable we now see in the repaired (centre) section a better record of how Michelangelo’s own painting had appeared than exists in the surviving sections of Michelangelo’s painting. By properly reading the testimony of this photographic record, we can calculate the scale of loss that ensued when Michelangelo’s own a secco work on the surface of his frescoes was removed.

By that method, Michelangelo had painted shadows onto his figures after the plaster had dried. After the recent removal of those shadows a figure emerged (as seen right) with arms that were apparently depicted flatly and without tonal modulation in a single local colour/tone by Michelangelo on either side of a section by Carnevale where the forms of the arms were fully modelled by dramatic shading. Could that ever have been the case? Would Carnevale have been allowed to conduct a master-class demonstration to Michelangelo on how to render painted forms sculpturally? Those who still defend this restoration – as some British newspaper art critics do – might attempt to offer some credible explanation for this startling visual and plastic mismatch, which presently stands as the largest elephant in the art restoration room.

The crime against art that this restoration constituted was compounded by art historical apologists who claimed that the Michelangelo everyone for nearly five centuries had thought existed, had never existed, and that a new, true Michelangelo who, far from being “essentially a sculptor” was “one of the great colourists of Western Art”, had been uncovered by courtesy of a single cleaning. To justify this historically revisionist and artistically subverting “outcome”, apologists for the restoration were obliged to offer one of the most cockamamie art historical/technical accounts: namely, that what had “deceived” Michelangelo’s own contemporaries and everyone else for nearly five centuries had been nothing more than the effects of dirt and soot that had slowly and imperceptibly accumulated on the ceiling’s frescoes over the centuries.

This deceiving filthy material had, the artistically credulous are invited to accept, artfully arranged itself around Michelangelo’s flat, bright, “colouristic” designs so as to mimic the effects of the very sculptural preoccupations for which Michelangelo was already famed. In due course, it was further suggested, this artful dirt and soot had been set in glue by successive restorers, who, on one occasion, it is said, did so while standing on the top of thirty feet high step-ladders while brandishing glue-filled sponges tied to the end of thirty feet long poles. When the Vatican authorities were challenged on this account (by us) they had to admit that no proof existed of any glues ever having been applied by any restorers. What the Vatican authorities might also have admitted is that a further indisputable technical proof of Michelangelo’s authorship of the glue-painting on the fresco surface had emerged in the 19th century when the Vatican made its own moveable scaffold available to the British painter Charles Heath Wilson – and that this testimony was known to them. On examining the ceiling, Wilson had found that:

“…the frescoes are extensively retouched with size-colour…evidently by the hand of Michelangelo”.

Wilson could not only see this glue painting on the plaster surface, he could touch it:

The colour readily melted on being touched with a wet finger and consisted of a finely ground black, mixed with a size…The shadows of the drapery have been boldy and solidly retouched with this size colour, as well as the shadows on the backgrounds. This is the case not only in the groups of the Prophets and the Sybils, but also in those of the Ancestors of Christ in the lunettes and the ornamental portions are retouched in the same way. The hair of the heads and beards of many of the figures are finished in size colour, whilst the shadows are also thus strengthened, other parts are glazed with the same material, and even portions of the fresco are passed over with the size, without any admixture of colour, precisely as the force of water colour drawings is increased with washes of gum…These retouchings, as usual with all the masters of the art at the time, constituted the finishing process or as Condivi expresses it, ‘l’ultima mano’.”

In addition to his expert (i.e. artist’s) testimony, Wilson offered two further material proofs of Michelangelo’s authorship that might otherwise have been expected to be considered clinching by today’s “scientific” restorers:

They [the retouchings] were evidently done all at the same time and therefore when the [original] scaffold was in its place.”

There can be no doubt that nearly all of this work is contemporary, and in one part only was there evidence of a later and incapable hand. The size colour has cracked as the plaster has cracked, but apart from this appearance of age, the retouchings have all the characteristics of original work.”

It is a matter of record that the ceiling cracked before any restorers went near it. If the size painting cracked with the plaster, it must have predated the cracking – and, therefore, also that of any restorer’s intervention. Or, to reverse the testimony: if the glue had been applied by restorers long after Michelangelo had painted the ceiling and long after the ceiling had cracked, as has been suggested, it would have run into the already extensive cracks – but it was not and it had not. We can thus be in no doubt that today’s restorers removed the final stages of Michelangelo’s own work; that the “New Michelangelo” they had “discovered” was nothing more than the mutilated remains of his original work that they had left on the ceiling; that no part of the ceiling had escaped the consequences of their labours.

The last restorers of Michelangelo’s ceiling frescoes seem not fully to have heeded the cautionary evidence of their predecessors’ mishaps. The warnings – both pictorial and documentary – were clear enough. We see in the photograph of the left hand of God from Michelangelo’s “The Separation of the Earth from the Waters” (Fig. 10) that there is today a great mismatch between the sleeve and the fragment of cuff that had been repaired by Carnivale. Engraved copies of the 18th and 19th centuries (see Figs. 8 & 9) suggest that losses of shading to God’s left arm preceded the latest restoration. Charles Heath Wilson, who complained of the ceiling’s filthy and neglected condition and believed that it would profit from cleaning, nonetheless warned in terms against any watery interventions. Not only had he found Michelangelo’s size-painting vulnerable to a wetted finger, he complained that parts of the ceiling had already “undoubtedly been injured by rude [restoration] hands, suggesting that glazing has been partially or entirely swept away” and that great restoration injuries had previously occurred when the ceiling had been “washed by labouring men with water in which a caustic has been mixed”. (For details of the recent water-based cleaning methods, see bottom right.) The consequences of water injuries had been set out by Wilson:

Thus great brushes or sponges have been swept over the skies and backgrounds and have not only removed dirt in a coarse unequal way, but have eaten into the colours and destroyed them in a variety of places. The Face, shoulder and arms of the prophet Daniel, various parts of the bodies and limbs of the young men sitting over the cornice and other portions of the frescoes have been nearly obliterated by this savage proceeding. The Injury done is irremediable, for the surface of Michelangelo’s work has been swept away.

Note particularly, here, the skilful placement of the darkest tones in the three corners of the pendentive. And, the masterly use of light and shade to articulate the roles of the principal and secondary figures. Pulling the (very sketchily drawn) group at the left out of their original shadow, as occurred in the recent restoration, did them no favours and did great violence to the disposition of Michelangelo’s own pictorial values. Few will doubt that Michelangelo had intended to place the greatest possible emphasis on his central crucified figure – an invention which constituted an astonishing tour de force in its day by means of the violent planar opposition of the knees, which are parallel with the picture plane, to that of the hands, which contrarily advance upon it at a near right angle. This great figural innovation is emphasised by the artist in the similarly acute foreshortening of the wall to the right of Haman.

The cleaning method here identified reads in part: “…Removal of retouchings and repaintings with a mixed gelatinous solvent, consisting of ammonium bicarbonate, sodium bicarbonate, Desogen (a surf-actant and anti-fungal agent), carboxymethylcellulose (a thixotropic agent), dissolved in distilled water. Mixture acts on contact. The times of application, rigorously measured, were: First application: 3 minutes, followed by removal, washing with water. Left to dry for 24 hours. Second application: 3 minutes, followed by removal, washing and leaving to dry as before. If necessary, and locally only, small applications, followed by plentiful final washing. In the case of salt efflorescences consisting of calcium carbonate, there was added to the solvent mixture a saturated solution of dimethylformamide…
Final treatment: the thorough, complete and overall application of a solution of Paraloid B72 diluted to 3% in organic solvent, removed from the surface of the pictorial skin by the combined action almost simultaneously of organic solvent and distilled water, which coagulates the surface acrylic resin dissolved by the solvent.”
