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.)

“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 Zacherias – top, 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.

NEW YEAR REPORT
Assaults on History: Dishing Donors; a Vatican Wobble; and, Reigniting an Old Battle of Hearts, Minds, Interests and Evidence
We had a good and eventful campaigning year in 2013. At home, ArtWatch was invited to speak in the Scottish Parliament for the interests of art and against a municipal arts bureaucracy seeking to overturn a prodigiously generous benefactor’s wishes and instructions in order, effectively, to reward its own negligence with an extension of powers and a major capital project (without clear costing). Our views on this proposal were carried in the October Museums Journal, the December Apollo (see Burrell pdf) and in the Sunday Times (Scotland). We found ourselves in the midst of a high-level museum world schism.
MacGregor versus Penny
Speaking for the overturning of Sir William Burrell’s terms of bequest was the Glaswegian director of the British Museum and former director of the National Gallery, Neil MacGregor. Mr MacGregor had agreed (presumably with the blessing of his trustees) to be co-opted as an adviser and declared partisan onto a Glasgow Life body – “Burrell Renaissance”. In support of Glasgow Life’s ambitions, MacGregor expressed with characteristic (lawerish) eloquence impatience with the length of time in which The Living might find themselves governed by the Wishes of the Dead. The present director of the National Gallery, Nicholas Penny (a scholar, rather than a populariser of others’ scholarship) spoke no less eloquently in opposition: “What is very often forgotten in discussions of this kind is the moral advantage and tangible benefit of a declared preference for honouring the wishes of the donor. Real concern for the future is always more persuasive in those who have a genuine feeling for the past.”
Parliamentary Concerns
The matter will come before the Scottish Parliament this month. Intriguingly, one of the members of the parliamentary committee that scrutinised the Burrell Lending request from Glasgow Life, Gordon MacDonald, SNP MSP, told yesterday’s Sunday Times (Scotland) that: “I too was concerned at the cost of £45m bearing in mind that Kelvingrove refurbishment cost £29m and they raised £2.5m from sponsorship and donations. The major work at the Burrell is a complete new roof and removal of lecture theatre to create new gallery space. Both of which will be costly, but £45m?”
Fresh Crimes Against Art and History
Internationally, two recent horrifically destructive mural restorations (the first in Spain and another in China, see Figs. 1 to 4) had reminded many of the great Sistine Chapel cleaning controversies of the 1980s and early 1990s (see “Restoration tragedies”). In January 2013 we were drawn back into that monumental Sistine Chapel restoration controversy (which had triggered ArtWatch’s founding in 1992) by an official acknowledgement that Michelangelo’s stripped-down ceiling frescoes were prey to failures of environmental regulation that were being exacerbated by swelling visitor numbers. We had warned against such failures twenty years earlier: “Artificially induced changes in moisture, heat and patterns of air convection can themselves do gross damage…The most obvious risk is that external air-borne pollutants will be pulled in.” (“The Physical Condition of the Sistine Ceiling”, Chapter IV, p.122, Art Restoration ~ The Culture, the Business and the Scandal, London, 1993.)
An Old Crime Implodes
At the beginning of last year, Antonio Paolucci, the director of the Vatican Museums, insisted that whatever the problems, visitor numbers could not be restricted: “We have entered the era of large-scale tourism, and millions want to enjoy our historical culture. Limiting numbers is unthinkable.” Today, the unthinkable may be on the cards. Paolucci acknowledges in this month’s Art Newspaper that the huge increases in visitor numbers (5,459,000 last year from 4m the year before) constitute his biggest practical problem:
“…The sheer numbers can be damaging, especially in the Sistine Chapel, which everyone wants to see. At the height of the season it gets 20,000 to 25,000 people a day, all breathing out carbon dioxide and vapour and bringing in dust. We are employing Carrier, a top US firm [who donated and installed the presently failing system] to work out a method of dealing with humidity; otherwise we will have to limit numbers…” (Emphasis added.)
On January 2nd Paolucci expressed further concerns in a Vatican museums press release: “I’m asking myself what will happen during the coming Easter holidays and the great canonization of Popes John XXIII and John Paul II. This will bring to Rome an immense mass of Catholics from every part of the world. Such extraordinary numbers oblige one to make some fundamental and priority considerations. The objective must be from now on to observe constant maintenance and preventive conservation of the Heritage. To do so we must provide ever more important resources.” At the same time, Paolucci promised that, after 3 years of work, all will be ready in May for the “improved air conditioning, reduction of pollutants and humidity control of the temperature.”
Antonio Paolucci, a distinguished Renaissance art scholar (and student of Roberto Longhi), might be thought to be in an impossible position as director of the Vatican’s museums. Presently, Michelangelo’s frescoes are being devoured by pollution and condensation that are the inescapable by-products of permitting the Sistine Chapel to serve as a tourism cash cow. At the time of the last restoration of the ceiling, the Vatican’s finances were a source of scandal (one of its bankers had been found hanged on a bridge in London). On December 7/8 last year the Financial Times reported “The Vatican bank was established to serve the work of the Catholic Church around the world. It has now become synonymous with financial scandal. An 11-month FT investigation reveals the extent of mismanagement at the Euros 5bn-asset bank and the murkiness of its operations that finally led regulators, international agencies, big banks and even Pope Francis himself to take action.” (Rachel Sanderson, “The Scandal at God’s Bank”.) In this climate, is cutting back visitors really an option? For that matter, is the new air-conditioning system promised for May capable of coping with yet further increases of visitors of the kind indicated by Paolucci?
In the absence of dramatic reductions of visitor numbers (which must presently be netting in excess of £75m p.a.) it is hard to see how any amount of conservation tinkering might resolve the present crisis. It would never be logistically possible to seal every visitor inside a “moon-suit” that would prevent the destructive cycles of evaporation and condensation that were already known in 1993 to be creating continuous migrations of salts and vapour within the frescoes. (At that date it was established that some 425 kilos of water were being pumped into the chapel’s microclimate by the daily total of 17,000 visitors. On today’s visits that volume of water must reach 600 kilos per day.)
No increase of expenditure could reverse the initial un-wisdom of stripping Michelangelo’s frescoes down to the bare plaster, thereby both bowdlerising his art and exposing its remains to environmental degradation. No expenditure could put back the glue painting with which Michelangelo had modified and intensified the sculptural presence of his figures and the unprecedented dramatically illuminated theatre which they occupied. Those characteristics had startled and awed his contemporaries. They were repeatedly recorded in copies made in Michelangelo’s own lifetime and for centuries afterwards (see, in particular the late 18th century copy opposite at Fig. 8).
The Vatican is presently attempting to rebuild the relationship between the Church and contemporary art that was sundered 200 years ago. It is a noble aim but it will remain a vain one until the corruption of art history that followed the restoration of Michelangelo’s ceiling is acknowledged and addessed. What Michelangelo achieved on the ceiling was unprecedented and precious: a profoundly spiritual fusion of the human and the divine that was rendered corporeal and situated in a palpable space contiguous with our own. Scholar supporters of the restoration claimed in defence of the emasculation of that original stupendous and unique achievement that we could now make “more sense” of Michelangelo; that we could now see a clearer link between his art and that of the inferiors who preceded and followed him. As long as the Church continues to endorse so unfounded, untenable an account, it will be in no moral position to forge any constructive relationship between itself and today’s artists.
If the cash flow is to be maintained and if Michelangelo is to be preserved, there would seem to be only one conceivable solution: as with other environmentally vulnerable archaeological/artistic sites, a full-size, absolutely faithful facsimile of the chapel will have to be built as a destination for the ever-swelling press of tourists. Creating an alternative “virtual” chapel might seem a shocking prospect and a colossal admission of failure but would it be more unpalatable than proceeding with the proposed plan described in our previous post to turn the remains of Michelangelo’s own frescoes into a “virtual” colourised caricature of themselves with 7,000 individually attuned colour-enhancing LED lights that would flood the ceiling with an artifical and chromatically falsifying light ten times more powerful than today’s? Building a facsimile to draw the tourists would mean that what survives of Michelangelo’s original work might then be left in peace, as it is, and once again in a congenial, stable climate.
Further and Fresh Doubts
On November 30th Peter Aspden, the Financial Times’s culture correspondent, declared that the restoration of Michelangelo’s Sistine Chapel frescoes (“the most important such project in recent history”) had been a “crushing disappointment”. Recalling that before restoration the frescoes had been “more real, more subtle, more moving”, Aspden noted that arguments in defence of the restoration “have been rebutted, with no little ferocity.” If Michelangelo’s Sistine Chapel frescoes remain the worst case of injuries suffered in the great post-war restoration bonanza, they are not alone. Fortunately there are increasing signs of doubts about modern restoration procedures elsewhere. Consider this further critique of picture restorers that emerged from a most surprising quarter on December 17th:
“…The problem is, each generation of conservators has always thought that they, uniquely, had the definitive solution to fixing works of art. In the world of pictures, today’s conservators spend much of their time undoing the earlier, bad restoration of their predecessors. For example, the dreadful wax re-lining technique all the rage only a generation or so ago is now routinely removed, as over time the wax creates a dull, thick layer which affects the paint surface. Before that, there was a fashion for planing down pictures on panel, and laying them onto canvas, with all the attendant holes and large losses that entailed (see for example the poor Bridgewater Raphaels in the National Gallery of Scotland). More recently, conservators thought they had invented a synthetic varnish that didn’t go yellow with age. But now we are discovering that it just goes grey instead. So the pictures have to be cleaned all over again. It’s a fact that over the course of art history more damage has been done to pictures by those claiming to be ‘conserving’ them than anything else. We can only wonder which of today’s foolproof conservation techniques will have to be rectified by tomorrow’s restorers. Sometimes I think it’s all a giant, inter-generational job creation scheme by some shadowy, global conservator’s union.”
We had noted on 12 July last year that “There has never been a make-work project like art restoration”, and earlier, on 17 March 2011, that “Art conservation is now a substantial vested interest, a business with a shifting ideology that serves as self-promotion… Regardless of conservators’ good intentions, the fact remains that their treatments alter the material fabric and aesthetic appearance of works of art. Alterations are made on promises to prolong life, prevent deteriorations and recover original conditions, when history repeatedly shows contrary outcomes”. Although we greatly welcome the recent tacit endorsement, its source is perplexing. The author, Bendor Grosvenor, made these remarks on his (lively and informative) blog, Art History News.
Art Market restorations
Mr Grosvenor, a modern historian by training, has for a number of years worked as a researcher and, latterly, as a second pair of eyes for the Mayfair art dealer, Philip Mould, who happens to be a highly active “stripper-downer” of paintings in search of something better and more valuable underneath. In countless BBC television programmes, in his 1995 book Sleepers and in his 2009 book Sleuth, Mr Mould has been a most effective propagandist for today’s professional restorers, of whom Grosvenor evidently now entertains doubts. Mould himself has conceded with increasing frequency that great risks attend the stripping down of paintings. When asked recently on the best method of cleaning pictures, he replied somewhat flippantly “With spit and polish” and made no mention of the solvents – principally acetone – and scalpels used by his own restorers. (We have been haunted for some years by advice given on how to remove nail varnish when no acetone nail varnish remover is to hand: brush on fresh nail varnish, leave for a few moments and then wipe off. The acetone in the new liquid varnish swiftly dissolves the old hard varnish enabling both to be removed with the same cloth.)
Concealment and Disclosure
With the public museum sector we feel compelled to examine the bizarre and perverse phenomenon of promoting demonstrably wrecked paintings in special loan exhibitions. One such is the Clark Institute’s Turner “Rockets and Blue Lights”, which work is once again being promoted in Britain as the Belle of Turner’s Ball, this time at the Greenwich Maritime Museum’s “Turner and the Sea” exhibition. As our colleague in New York, Ruth Osborne, has established, another such restoration-wrecked picture hangs in the Frick Collection as an autograph Vermeer (“Vermeer Interrupted: A Study of Johannes Vermeer’s ‘Girl Interrupted at Her Music’ at The Frick Collection”). The Frick has refused to release to ArtWatch an archive photograph that shows the frequently undone and redone picture at its most pictorially deranged and incoherent “in-restoration” state. A copy of that photograph is held by the Getty Institute but it cannot be released because of the Frick’s enforcement of copyright ownership. All but the most informed visitors to the Frick will likely have no inkling of what lies beneath the present surface. Where Philip Mould seeks to identify and uncover works of quality that have been distorted by later accretions (- the art trade’s “sleepers”), the Frick presently conspires to pass off tricked-up underlying pictorial carnage as Vermeer’s own handiwork.
The Frick is not alone. The Phillips Collection in Washington has repeatedly spurned our requests to examine the conservation and filmed records of the Kecks’ ruination of Renoir’s “Luncheon of the Boating Party”. Museums have grown bolder in promoting their own conservation efforts, sometimes placing restorers behind glass walls to permit public scrutiny. This seeming increase of public accessibility can have an ulterior motive: one leading international conservator disclosed that the practice serves to prevent embarrassing public outbreaks of shock and indignation when familiar works are unveiled after long incarceration in conservation studios. A Turner painting currently undergoing such public exposure is running at the Bowes Museum where the restorer is presently taking a break after encountering difficulties not identified by preliminary “scientific investigations” – the very type of investigation in which Philip Mould has expressed great confidence.
As we have seen in a number of televised Mould restorations, carrying out preliminary scientific tests does not eliminate surprises in the course of restoration once restorers start swiftly cutting through varnishes with their swabs and solvents to get to the paint underneath. We remain sceptical of the value of preliminary scientific or chemical analyses, not least because, as in the case of Michelangelo’s Sistine Chapel ceiling, the analysis said to “prove” the artist had not completed his frescoes with glue-based painting conflicts with other more relevant – and, in fact, irrefutable – proofs of the kind often demonstrated on this site, as here today at Figs.13, 14 and 15.
ArtWatch has another full and ideologically challenging year ahead but a first priority will be to demonstrate the extent to which naïve and misplaced faith in today’s restorers can make professional monkeys of scholars, curators and trustees.

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

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

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.
ArtWatch Stock-taking and the Sistine Chapel Conservation Debacle
ArtWatch is entering its twenty-first campaigning year with strengthening critical bite. The new ArtWatch UK website greatly extended the published reach of our Journal (see Figs. 1-4), attracting 22,000 visits in its first year and 52,000 visits last year, half coming from the UK and the USA and the rest from 139 other countries. With this post our archive comprises 59 articles by 8 authors. In New York the ArtWatch International site has been revivified under its new director, Einav Zamir. In France our colleagues in the Association Internationale pour le Respect de l’Intégrité du Patrimoine Artistique (ARIPA) have re-structured their website which now carries much of the contents of their excellent, rigorous journal, Nuances. Our efforts now attract fewer hostile and more respectful responses. We enjoy (sotto voce) support at high levels in many quarters – including among some conservators – and we sometimes earn outright vindication, as shown below. International and national press interest in our campaigns remains high. Unfortunately, in the art world itself many players remain in official denial on the subject of restoration injuries. They can see and admit that this is wrong and that that is wrong, but not that pictures are still being injured in restoration.
Our debut post on 12 December 2010, “The New Relativisms and the Death of ‘Authenticity’”, contrasted the consequences of musical and pictorial reconstructions. Last May, in a fascinating talk (“The Pursuit of Excellence: A Call to Arms”) at the 4th annual Lufthansa Lecture, at St John’s Smith Square, London, Andrew Manze, a former baroque violinist and Artistic Director of the English Concert and now Principal Conductor and Artistic Director of the Helsingborg Symphony Orchestra, noted: “Musicians are lucky that they can do no permanent harm to their material compared to the irreversible damage inflicted on the plastic arts, as reported by the ArtWatch organization for example…”
Our second post on the 13 December 2010 (“An Appeal from Poland”) drew an immediate response. Distinguished scholars, curators and conservators in Poland had asked ArtWatch UK to support their opposition to a proposed loan of Leonardo’s “Lady with an Ermine” to the National Gallery (see “The National Gallery’s £1.5bn Leonardo restoration”). We were then attacked in Poland – abusively – by Count Adam Zamoyski, chairman of the Princes Czartoryski Foundation which had agreed to loan the many-times borrowed Leonardo for a substantial fee. It was later reported from Poland that: “In order to improve the functioning of the Foundation of the Czartoryski Princes and to assure the correct collaboration with the National Museum in Krakow”, Prince Adam Karol Czartoryski of the Czartoryski Museum had dismissed the entire board and its chairman, his cousin, Count Adam Zamoyski. Although the contracted loan went ahead it was announced that the fragile panel painting would not travel again for at least a decade.
Our posts of 8 February and 14 March 2012 produced evidence of a mis-reconstructed sleeve of Christ in Leonardo da Vinci’s “Last Supper”. This was reported in the Independent of 14 March 2012. In the National Geographic special issue “Exploring History” it is said that: “Generally lauded by art historians and appreciators, the restored work has aroused controversy. Some say too little of Leonardo’s paint is left, or cavil about the mural’s altered forms…As the debate wears on, we at least – and at last – have a legible ‘Last Supper’ to savor.” “Legible-but-false” could stand as a motto in those museum conservation departments where restorers paint photographically manipulated “virtual realities” onto old master pictures.
Last week our November 12 post on a Black and White Michelangelo drew an artistically perceptive endorsement from the painter and art critic, Gerry Bell. ArtWatch’s genesis was rooted in the tumultuous battles over the 1980-1990s Sistine Chapel restoration battles. That controversy has recently re-combusted – and in precisely the manner we had anticipated two decades ago in the 1993 James Beck/Michael Daley book “Art Restoration: The Culture, the Business and the Scandal”. 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 also 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 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 our next post we examine the consequences of the last restoration and its contributory role in the present crisis – a crisis for which the blame is brazenly being shifted by the authorities from the authorities and on to the (paying) visitors.
