Ghosts in the Lecture Room: Connoisseurship and the Making, Appraising, Replicating and Undoing of Art’s Images

18 May 2014

On the 3rd of May, the Mellon Centre hosted a lively conference on the divisive subject of art connoisseurship – “The Educated Eye?”, now available on Webinar ( Yesterday, a three-day congress opened at the Hague on “Authentication in Art” (7-9 May) carrying the subtitle “What happens when the painting you are buying, selling, investigating, exhibiting, insuring – Turns Out to be a Fake or a (Re)Discovery…” A small ground-breaking exhibition with bearing on the two conferences (“Diverse Maniere: Piranesi, Fantasy and Excess” – see below and Figs. 1 and 2) is running at the Soane Museum until May 31st.

Curating the Future

The question mark in the Mellon Centre’s conference title, reflects persisting antipathies to connoisseurship, which practice/discipline/pose nonetheless shows signs of rehabilitation. The conference proved admirably even-handed “ideologically” but somewhat constricted in its composition and terms of engagement.

The first speaker, Dr Stephen Deuchar, a former director of Tate Britain who has followed a former chairman of the Tate’s board (David Verey) into the Art Fund’s management, might be taken to represent the official modernist/progressivist museum world establishment. In his paper, “Connoisseurship Now: Some Thoughts”, Dr Deuchar disclosed that the Art Fund no longer confines itself to helping museums buy great works of art that might otherwise be lost to the nation, and now, for example, has contributed “generously” towards something involving the conceptualist Martin Creed (who turns lights on and off), even though no object will be acquired. Gifting this munificence to the Tate required Deuchar (and, perhaps, his chairman?) to step aside from the trustees’ deliberations.

There were two problems with Deuchar’s position. First, in espousing a Connoisseurship of The New-and-the-Forthcoming, the curator effectively operates blind in bandit territory. As the National Gallery’s director, Nicholas Penny, has pointed out, it takes time to evaluate new art, we cannot yet know how it will compare with other art that will shortly follow, or with other yet-to-be-seen contemporary art. Second, his position is old hat and inadvisable: in the 1960s and the 1970s critics championed contemporary art not on quality but on the degree to which it “challenged” existing art practices. So-called “New Activities” were heavily promoted by such critics and curators as Richard Cork and Sir Nicholas Serota of the Museum of Modern Art, Oxford, the Whitechapel Gallery and, for the last twenty-six years, the Tate. With the dismantling of quality as the principal criterion of judgement, and with the aid of the state-funded, respectability-conferring Arts Council, new activities soon became official activities, leaving most fine art practices and practitioners marginalised. Few noticed that “fine art” had cut itself off from related design and craft activities, and from its own history, to become a cosseted licensed playground where rules were the property of “artists” who played by no rules.

Culturally determinist Marxist art historians (like John Berger and, for a while, Peter Fuller), had gone further; had become more mystical and taken to praising art that they judged to have “anticipated the future”. Insofar as art might ever be said to do such a thing, it could only be seen to have done so in retrospect. When asked to comment on the significance of the French Revolution, the connoisseur of history, Mao Tse Tung, replied, “It’s too soon to say”.

The New Art History

The Mellon conference pitted (trade) chalk against (museum) cheese with Dr Bendor Grosvenor of the Philip Mould gallery and Dr Martin Myrone, a Tate curator and champion of the New Art History which pursues the socially signifcant in favour of the aesthetically desirable (“The Limit of Connoisseurship”). In the course of his conceptually suave paper, “Why Connoisseurship Matters”, Dr Grosvenor made two startling disclosures. First, having just seen Michelangelo’s Sistine Chapel ceiling, he now appreciates that the critics he had held to be “myopic” – were right all along: Michelangelo’s work has indeed been ruined. Second, that he stands behind restorers to prevent them from destroying glazes on Van Dyck paintings. (See Figs. 12a to 15.)

Dr Myrone declared allegiance to the New Art History where the social has routed the aesthetic. The resulting knock-about reminded this observer of days on the New Left in the late 1960s when Kim Howells, a rebellious Hornsey College of Art student (but later a New Labour government junior minister), wanted all potentially saleable object-based art to be outlawed – unlike the “democratising” mass medium of TV in which he was dabbling. When we asked Howells how he regarded Goya’s Horrors of War etchings, he replied that, although in sympathy with the works’ politics, the fact that they were printed on paper, “which is a capitalist commodity”, meant that they, too, would have to go. Dr Howells later grew up artistically and, as a visiting minister to the Tate, left a rude comment on a Turner Prize exhibition. Soon after, he lost his place in government.

Parts and Wholes

The afternoon session paired Spike Bucklow, the Hamilton Kerr Institute’s Senior Research Scientist (“Connoisseurship, technical knowledge and conservation”), and the British Museum’s head of prints and drawings, Hugo Chapman (“Dodging the label connoisseur from Christie’s to the British Museum”). Mr Chapman told how, when working in trade (Christie’s), he had been advised to describe himself as “an expert” rather than a connoisseur. It seems that the public can more easily forgive mistakes made by the former. Chapman told a story about a librarian who once hid a key drawing from an artist’s box when showing it to a scholar, and then, when duly reviewing the scholar’s book, professed himself astonished that no mention had been made of the said drawing.

The Hamilton Kerr conservator opted to address small things because “fragments are easier than wholes”, while the embarrassed-connoisseur attempted (more sensibly) to make artistic sense of the whole effects of drawings, and to understand, thereby, how they were executed. Dr Bucklow first showed how eloquently cracks on paintings can testify to a picture’s age, medium, underlying support, country of origin and so on. Having thus demonstrated an evidently usefully diagnostic tool (a kind of Connoisseurship of Cracks), he dismantled his own edifice by demonstrating how the vagaries of individual works’ histories and compositions so complicate the system as to render it effectively useless.

Mr Chapman, while conceding the very great difficulties of making sensible identifications of authorship in drawings, described how he tried to establish Michelangelo’s authorship of a drawing by considering its overall relationships and effects. In a nod towards Myrone’s position, he conceded that because many works in collections are ephemera, it would be futile to attempt to establish authorship of every piece of paper, even though such works often have great social significance and interest.

Salvage Operation

In the final paper (“New Connoisseurship, Old Europe, and the Future of Art history”), Professor Liz Prettejohn, head of York University’s Department of Art History, made a spirited attempt to retain a still-vital discipline that might be free of the more toxic ingredients of past connoisseurship practices. Prof. Prettejohn’s credentials in this respect were well established by a demonstration of her undergraduate response to a formal analysis test set by an old-style connoisseur professor. Prettejohn showed a Rembrandt etching about which students who had been reared exclusively on the study of modern art had been able to volunteer only that it was “old” and “probably Victorian”.

A Missing Link

This constructive, even illuminating, conference had two constricting deficiencies. First, connoisseurship’s purpose was largely confined to determining authorship, with, Dr Grosvenor’s startling asides apart, no consideration given to the urgent need to appraise restorers’ often radically transforming changes – an unforgivable lapse given that unsound attributions can always be corrected, while bad restorations are forever. Second, no artists contributed to this conference. While all speakers addressed the problem of producing an Educated Eye, none seemed aware that nothing educates the eye faster than producing or copying art. With artists, critical faculties were developed in academies and art schools by doing rather than by reading about or simply looking at. Listening to conscientious people grappling with the difficulties of connoisseurship while seemingly indifferent to or ignorant of art practices and blasé about restoration injuries, left an impression of a profession viewing fundamental problems through the wrong end of a telescope.

It is no accident that artists have initiated most of the great picture-cleaning controversies. Those who create art best identify injuries to it. The present state might easily be corrected: it would take small resources to have student scholars make brief drawn copies of the works they study, thereby appreciating art’s vital mind/eye/hand connections. Appreciation and discrimination may be of the theoretical essence in connoisseurship, but taken alone, without knowledge of and engagement with art’s practices, they leave practitioners susceptible to the traditional charge of being pretentious poseurs.

Drawn to Distinguish

Hugo Chapman’s sound quest to grasp the logic of the whole triggered theoretical and practical thoughts. Drawing provides the best route into questions of connoisseurship, being the most private, direct and likely entirely autograph form of image-making. If trainee art historians were required to make different types of drawing, even for brief periods, it would be incalculably helpful in establishing connections between historical artefacts and their original purpose.

Students might, for example, practice drawing as Rodin did with his famous late quick figure studies – never taking their eyes off the model while enclosing a complete figure with a swift continuous contour. Rodin did so, he explained, to fix in his memory the unique total effect of the body – its gestalt – and to test his own grasp of the miracles he had observed. The means required for drawing are miniscule: an American newspaper illustrator who illustrated first night performances of plays concealed a small pad and a very short pencil in a jacket pocket so that he could make discretely drawn notes of the actors to use later to prepare his finished illustrations.

By helping to fix images in the mind, drawing is the very opposite of taking photographs, which practice can evade thought and appraisal. Rodin once reproached himself for having failed to appreciate that the most important part of a head lay not in any of its individual features but in the manner in which they were all fused into a whole. In perverse contrast, the decision to restore the entire cycle of Michelangelo’s Sistine Chapel frescoes was made not on any analysis of the whole and its internal relationships but on the basis of brief chemical tests made on a single lunette (the sections of wall above the arched windows in the Chapel) that happened to be within the reach of restorers who were working on minor frescoes. Misplaced faith in the validity of those “scientific” tests (of an insufficiently tested cleaning agent – it was later discovered to have etched the surfaces of stone, producing corrugations that scattered light, rather than to have cleaned them) permitted the Vatican’s curators and restorers to launch a cleaning programme on the entire fresco scheme with uniform and pre-determined applications of a single, ferocious stone-cleaning material (a soda, ammonia and detergent cocktail) even though, to those with eyes to see, the lunettes had played a subdued and subordinate role to the ceiling proper in Michelangelo’s grand scheme. (See Figs. 4 to 9.)

There is a another way

By all accounts, the finest, least controversial, most sensitive picture restorer working in Britain in the 20th century was the German émigré, Dr. Johannes Hell. His method was utterly respectful of the whole and overall effects of pictures. Dr Hell had trained first as a fine artist and then taken a doctorate on Rembrandt’s drawings. He deplored restorers’ practice of cutting “windows” through (assumed) dirt and varnish until bright colours and light tones are exposed (as at Fig. 7). He worked overall on the entire surface of a picture with the mildest solvents so that no optically and conceptually deranging relationships could emerge. His slow method was made slower by frequently “resting” a picture to give it time to air out, so that no corrosive solvents might accumulate within the paint layers. With Hell’s method in mind, it can be painful to consider the haste in which today’s restorers procede with their swabs, acetone, scalpels and “windows” when in pursuit of more authentic and original paint underneath a picture’s surface.

Connoisseurship in action

We take a degree of pride in the fact that the (proper) exercising of connoisseurship has been alive and flourishing within this organisation for over two decades. From its inception in 1992, Artwatch has deployed aesthetic discrimination and visual analysis in demonstrations of injuries made during “conservation treatments”. Specifically and in terms of methodology, we have done so by the correlation of photographic records of the pre and post-restoration states of works. (This website was custom-made to carry directly corresponding images side by side or in continuous vertical sequences so as to facilitate the most directly revealing visual comparisons.) In the Witt Library, we see photographic records that do not just assist the making of attributions but that also record the progressive debilitation of paintings over successive restorations. We notice that the difference between an authentic work and a close copy can be far smaller than that between an authentic work seen before and after a bad restoration. Dr Grosvenor really did not need to wait until he could join the scrum in the Sistine Chapel to appreciate that Michelangelo’s work has been ruined – he needed only to study the countless pre and post-restoration photographic records that we have carried on this site and had described earlier at length in the 1993 (James Beck and Michael Daley) book “Art Restoration ~ The Culture, the Business and the Scandal”.

The nature of evidence

Defenders of restorations often say that they cannot be judged on photographic evidence. In other regards, art dealers have great faith in the veracity of photographs – they will bid online on the strength of a single photograph. Bernard Berenson preferred to examine Michelangelo’s ceiling by looking at large photographs in books rather than by eye when craning his neck in the chapel. We should be clear on two points: there are no good grounds for disregarding photographic proofs of restoration injuries; the kind of evaluative test that Prof. Prettejohn’s old style connoisseur teacher devised for undergraduates might just as profitably be applied to analysing the differences between pre and post-restoration conditions. (See “An Old Style Connoisseur Test for Undergraduate Art Historians:” opposite.)

For all the social alertness of the New Art Historians, little comment has been made on the major organisational and “ideological” changes within the museum world over the last half century or so. In our view, the failure of scholars and curators to heed artists’ complaints stems from the fact that they have allowed themselves to become dependent on the technical expertise of the very many restorers who have become institutionally embedded throughout the museum world. It is now restorers not painters who pontificate on the making of paintings. It is they who insist that photographic records of their own “treatments” may not be held up and used in evidence against their actions.

Speaking generally, as an organisation, we are bemused by a profession that uses photographs for all manner of curatorial, scholarly and critical ends except for the indentification of restoration injuries. Scholars now routinely revise their own professional scholarly accounts in order to bring them into line with restorers’ latest, often radical, transformations. In the published accounts of restorers and curators alike, nothing ever counts as an injury – every change is presented with drum rolls as a “discovery”. Whole steamships, Vermeer necklaces and sheep can go missing without an art historical murmur or any ruffling of connoisseurs’ feathers. Even in terms of attributions, Artwatch has been pro-active on the connoisseurship front.

The misappliance of science and early calls for the the return of connoisseurship

While protesting since the early 1990s against the cult of “scientific” conservation and its disparagement of “subjective” aesthetic judgements, we have throughout commended a return to proper and rigorous applications of connoisseurship. In the October 1994 Art Review article “How to Make a Michelangelo”, we suggested that “The fact that our scholars and technical experts flit quite so promiscuously through time and space might suggest uncertainty of connoisseurship and ability to ‘read’ paintings”. Three years later, in connection with another National Gallery attribution, we wrote: “In recent years the art of connoisseurship has become entangled with the scientific analysis of paintings. Problems of attribution, once resolved by the educated ‘eyes’ of individuals, are increasingly seen as the property of interdisciplinary teams of curators, restorers and scientists who enjoy the technical, financial and professional support afforded by large museums. But how sound are the new proceedures – and how reliable are the published accounts given of them?” (Art Review, July/August 1997, “Is this really a Rubens?”).

In truth, it might fairly be said that the campaigning essence of Artwatch has been a constant assertion of the primary value of visual connoisseurship – see also, “Is Michelangelo’s Entombment in the National Gallery by Michelangelo?” by James Beck in the Gazette des Beaux Arts, CXXXVIII, 1996. We have devoted two entire ArtWatch UK journals to critiques, successively formulated and advanced by the painter/scholars Euphrosyne Doxiadis and Dr Kasia Pisarek, of the National Gallery’s Rubens “Samson and Delilah” attribution. The title of the last book (2006) by ArtWatch’s founder, the late Prof. James Beck, was “From Duccio to Raphael: Connoisseurship in Crisis”. It received few reviews – and no mention at the Mellon Centre conference.

A connoisseur of Ephemera

No mention was made, either, of a remarkable new work of scholarship published last year by the British Library and the Oak Knoll Press in the USA – Michael Twyman’s “A history of chromolithography ~ printed colour for all” – which we first encountered in the Institute of Conservation’s Chantry Library, Oxford. The ingenious lengths to which printers went in the pre-photographic era to replicate any image, and all things in the world, in reliable colour on multiple, co-ordinated slabs of stone is truly astonishing to behold (see Fig. 3). It is impossible to exaggerate either the illuminating usefulness of this major, beautifully produced book, or the sheer delightfulness of its immense pictorial riches. For those who might feel that a major tome on a history of a printing method might make for dull or excessively technical reading, we would urge, “think again”: here are to be found ephemera (printed bills, advertising cards and the likes) alongside early pioneering hand-drawn attempts faithfully to produce such elusive epically heroic fine art subjects as paintings by Turner and Michelangelo. The faithfulfulness of the attempts to replicate the values of the most hallowed artists summoned applications of great sensibility and powers of aesthetic discrimination. Here, the connoisseur, the scholar, the social historian, the technical historian and the lover of fine drawing and colouring might all feast together, in awe at the dedication, the talent, the artistic insight found in an unsung publishing trade.

We were delighted, for example, to find so full an account of the production of Robert Carrick’s 30 x 44 inches 1852 chromolithographic copy of Turner’s “ Rockets and Blue Lights…” made in no fewer than fourteen colour separations (see Fig. 9). That faithfully made, expensive and then state of the art record (“the only perfect reproduction of a picture ever issued” – as it was claimed to have been in 1900) testifies indisputably to the destruction of the principal boat in the painting on which we have commented a number of times, most recently on the obtuse (or brazen) presentation of this wrecked picture as a jewel in Turner’s crown – see “From Veronese to Turner, Celebrating Restoration-Wrecked Pictures”.

Even more importantly, there is also reproduced, in its entirety, a massive 1,027 x 470 mm (40 by 27 inches) faithful cartography-like, on-the-flat, full colour image of 1852-53, that simultaneously depicts the entire curving geometries of Michelangelo’s combined ceiling and upper walls decorations (see Figs. 4 to 8). We had never before seen this work in its entirety. It reproduces every single figure (there are over three hundred) and architectural motif Michelangelo depicted. Most preciously of all, this encyclopaedic record testifies to the hierarchy of values within which Michelangelo situated his images.

By capturing the tonal and chromatic logic of the whole, not the fragment, of Michelangelo’s murals, this hand-drawn lithograph corroborates precisely the written testimony of the painter Charles Heath Wilson who examined the ceiling on a special scaffold in the 19th century. All parts of this great pictorial ensemble were not equal in their treatment. The “outer” section (as here seen at Figs. 4 and 5) was the semi-circular sections of painting made around the windows on the upper walls (the lunettes). They were the darkest passages of painting. They contained in their illusionistic recesses (see Fig. 7) depictions of the ancestors of Christ. This dark band of human figures set Michelangelo’s work apart from the wall paintings below – as did his great escalation of scale in his figures. Far from being an arbitrary but precisely situated zone of dirt, as the Vatican authorities preposterously and against all scholarly records claimed, this dark zone served aesthetically and symbolically as a kind of visual plinth for the even more monumental figures and the Divine Events depicted above on the ceiling. The next row comprised an architectural screen against which Michelangelo’s stupendous giant prophets and sibyls were set and relieved in the brilliant cinematic, shadows-casting light we have previously described. Above them, set in the sky glimpsed through illusionistic apertures in ceiling’s architectural scheme are the biblical scenes and the depictions of God Himself – Whose restoration injuries we have also chronicled. Today, by the miracles of our technology, we can see and move around the entire, now restoration-ruined surfaces of the Sistine Chapel, but the Vatican will not release a TV film made in the 1960s of the pre-restored state. Recent technical advances have carried us into a world where it is possible to produce perfect facsimiles not only of images but of three-dimensional objects and, even architectural spaces and forms.


The small exhibition currently showing at the Soane Museum shows three-dimensional realisations of graphic inventions of Piranesi by the foundation Factum Arte. A full size replica made by the foundation of Tutankhamun’s tomb in Egypt was unveiled this week. It was reported by Peter Aspden in the Financial Times “Fit for a king: Tutankhamun’s replica burial chamber”(see Fig.). Such technical capacities for replication raise issues that we will explore in coming posts. This fertile new territory is one for which scholars and connoisseurs will be ill-prepared to assess for as long as they ignore the mistreatment of unique and historic art objects by technicians who transform them into synthetic, polished replications of their (assumed) original autograph states. This website launched in 2010 with a discussion on authenticity in art and music (“The New Relativisms and the Death of ‘Authenticity'”). It did so in response to a restorer’s imposition (in new but deceivingly aged and cracked paint) of a piece of computer-generated “virtual reality” onto Holbein’s The Ambassadors. Connoisseurship is more urgently needed today than ever.

Above, figs. 4 and 5: Top, a detail, and, above, the whole of a lithograph printed, probably, in twenty-one colours on two sheets of paper, showing the entire Sistine Chapel ceiling and adjoining sections of the chapel’s upper walls and windows. The lithograph measures 1,027 x 470mm and was made from an 1853 drawing by Pratesi by C. Köpper under the art direction of L. Gruner and supervision of J. Storch at Winckelmann and Sons, Berlin.
The lithograph is reproduced in Michael Twyman’s “A history of Chromolithography”, with the image running across the book’s centrefold as seen here at Fig. 5.
Above, Figs. 6a and 6b: Left, the section of wall and ceiling in the Sistine Chapel that adjoins the wall of Michelangelo’s Last Judgement (here seen the thin dark strip on the right of the photograph). In this photograph, taken before the last restoration, we still see the dark zone of the lunettes which set Michelangelo’s frescoes apart from those on the walls below, much as had been reproduced in C. Köpper’s 1852-53 lithograph shown above at Figs. 4 and 5. Fig. 6b: The photograph on the right was taken after the cleaning of the lunettes and the ceiling, but before the cleaning of the Last Judgement. We see here how the former clear pictorial articulation between Michelangelo’s wall painting and that by others below it has been erased. At this stage, the not-yet-cleaned Last Judgement, seen in the bottom right-hand corner, is glaringly out of tone with the rest of Michelangelo’s work.

This photo-comparison was one of a number of such published in a December 1989 article, “SALVIAMO ALMENO il Giudizio Universale”, in the art magazine Oggi e Domani by the sculptor Venanzo Crocetti. As a young man Crocetti had worked on a restoration of the Sistine Chapel ceiling in the 1930s and was one of the earliest critics of the last restoration. His photo-comparison shows the inversions of relative pictorial value that occurred; where what was once darker-than, becomes lighter-than, and vice versa; when, if the work had simply been cleaned, the lights would have become lighter and the darks would have become darker. Such inversions of pictorial value only arise when paint is lost. And, yet, in defence of this cleaning, one of the co-directors of the restoration, the Vatican Museums’ curator, Fabrizio Mancinelli, claimed that his cleaning had led to the “surprising conclusion that the kind of suggestive painting by shadows for which Michelangelo was admired until a few years ago was essentially the product of candle-smoke and still more of glue varnishes”.

The image is 760 x 565mm.
It was unusual for important, original works of art to be brought to the chromolithographers’ studios because of the obvious dangers. Michael Twyman reveals in his chapter “Visuals and the Visualiser” that in the case of Turner’s Rockets and Blue Lights, this was done by William Day of the firm Day & Son because the printing and publishing house wished to make a reproduction that would serve as a demonstration of the firm’s capabilities in chromolithography.

An Old Style Connoisseur test for undergraduate art historians:
Compare the two sets of details of Van Dyck’s portrait Lucy Percy, Countess of Carlisle, (shown left before cleaning, and, right, after cleaning) in terms of: a) their relative vivacity as image and as a portrayal of the subject; b) their tonal gradations; and, c) their colouring.

The details on the left are as reproduced in the Tate Gallery’s 1992 catalogue to the 1992-1993 exhibition organised by Andrew Wilton, “The Swagger Portrait”. The details on the right are from the catalogue to the Tate Gallery’s 2009 exhibition, “Van Dyck in Britain”.

The Continuing Questions for Undergraduates here are: e) Are the drawing and the modelling in the flesh areas clearer and stronger on the top detail or that immediately above? f) Could the removal of discoloured varnish alone account for the dramatic chromatic change in the fabric of the dress? g) Was any other colour than blue discernable in the dress as seen before restoration? h) Has any loss of velatura occured in the course of the cleaning? i) Are all the changes that have occured in this painting attributable to a straightforward removal of surface dirt and discoloured varnish? j) Can we expect the painting to return to its previous subtlety and richness of colouring – and strength of modelling – when its present varnish discolours?

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.

(See The “World’s worst restoration” and the Death of Authenticity, and The Battle of Borja: Cecilia Giménez, Restoration Monkeys, Paediatricians, Titian and Great Women Conservators.) The fame of the incident led to a great increase of visitors to the parish church in Borja, Spain. The church imposed an entrance charge. At the end of December the parish priest was arrested for what the Daily Telegraph reports as “suspicion of misappropriating funds [£174,000], of money laundering and sexual abuse”.
Above, Fig. 2: The Daily Telegraph’s report of 23 October 2013 on the Chinese Government-approved, £100,000 restoration during which a Qing dynasty temple fresco was entirely obliterated by luridly colourised repainting. This crime against art and heritage came to light when a student posted comparative photographs online. In the resulting furore, a government official from the city responsible for the temple described the restoration as “an unauthorised project”.
Above, Figs. 3 and 4: The Telegraph reported that Wang Jinyu, an expert on fresco restoration from the Dunhuang Academy, had said the intervention could not be called “restoration, or [even] destructive restoration” because “[It is] the destruction of cultural relics since the original relics no longer exist”. It was noted that the case had echoes of a headline-grabbing incident last year when an elderly parishioner performed “a disastrous restoration” on a 19th century fresco of Christ in the Spanish town of Borja. One Chinese website user wrote. “They have turned a classic painting into graffiti. It looks like something out of Disneyland, doesn’t it?”
Above, Fig. 5: Above: Michelangelo’s prophet Daniel from the Sistine Chapel Ceiling, before (left) and after (right) cleaning. The great brightening of colours, simplifications and flattening of design, and destruction of shading and modelling that occurred during restoration led many to complain of the “Disneyfication” of Michelangelo’s work. Note particularly here the loss of folds on the drapery over the shoulder to the left, and the loss of the previous dark shadow to the right of that drapery. Supporters of the restoration defended such alterations on the grounds that Michelangelo had originally painted over-brightly and without chiaroscuro in order that his images would “read” through the gloom of a smokey, candle-lit chapel. Today, despite the creation of a hugely increased chromaticism during the restoration, the Vatican authorites are contending that there needs to be a ten-fold increase in the (artificial) lighting of the ceiling because the present lighting creates a “low-contrast twilight that fails to bring out the colours in Michelangelo’s masterpiece”. Have the colours faded to a tenth of their previous intensity over the last twenty years?
Above, Fig. 6: A greyscale version of Fig. 5. The contention that Michelangelo’s work needs ever-more artificial illumination is ironic – and, in truth, confessional. When his painting was originally unveiled in 1512, observers were stunned not by any brilliance of colouring (no one mentioned his colouring) but by the fact that the artist had given such great emphasis to light and shade, and to “sculptural” modelling in between his great tonal contrasts, that his figures appeared real, not painted, and that they seemed to be occupying real space and not merely decorating surfaces. Experts marvelled that such were Michelangelo’s powers of design that surfaces on the ceiling that were actually advancing towards the viewer, appeared to recede because his his brilliantly conjured illusion of perspective. This novel and revolutionary development was recognised for nearly five centuries…until the last restoration. There are no historical or artistic grounds for accepting claims that the unexpected restoration changes constitute miraculous “revelations” of original values.
Above, Fig. 7: Michelangelo’s sculpture of Moses from the tomb of Pope Julius II. In this reproduction we see how light and shadows are trapped/made by the architectural projections. In painting his monumental figures on the Sistine ceiling Michelangelo mimicked the kind of lights and shades that are seen on sculpture placed in architectural contexts, according to the (given) light source. We know that Michelangelo had done so on the ceiling because his effects were described and copied by his contemporaries and then by copyists in following centuries. Defenders of the restoration have claimed that scientific (i. e. chemical) tests, or “diagnostic analysis”, proved that, contrary to previous understanding, Michelangelo had not “modelled” his forms on the ceiling with tonal gradations but that he had modelled principally with colour. This is easily disproved: had Michelangelo constructed his forms with shifting colour values, then all black and white photographs and all black and white engraved copies of the ceiling would look less sculptural. Demonstrably, that is not the case. Similarly, if Michelangelo had constructed his forms by colour, removing the material described by restorers as dirt or varnish, would have produced images more sculptural than before the “cleaning”. That this was not the case is seen in the before and after photographs in colour first at Fig. 5, and then in greyscale at Fig. 6.
Above, Fig. 8: This engraving (of c. 1790) of Michelangelo’s Prophet Daniel shows intense, almost “cinematic” contrasts of light and shade and of very strong shadows that appear to have been cast by the depicted forms and draperies. As such, this image accords perfectly with the responses of Michelangelo’s contemporaries when the ceiling was first painted. It accords with accounts of Michelangelo producing model sculptures of figures that he was painting, in order to study the shadows that would be cast onto the ground or onto adjacent walls. Those who had studied the frescoes’ surfaces at close quarters (before the the last restoration) concluded that Michelangelo had reinforced the shadows on the ceiling with glue-paints carrying black pigment.
Above, left, Fig. 9: This section of the Prophet Daniel seen before cleaning (left) and after cleaning (right) shows stronger shadows and modelling before the restoration. Moreover, it shows that Michelangelo used the black glue-paints to revise the drawing and the modelling in the section of drapery on our left that hangs from Daniel’s right shoulder. When restorers remove material that changes the design of paintings, they usually claim that what was removed was not original but had been applied by previous restorers. That argument can easily be shown to be spurious in this case: where complete records of copies exist, it can be shown that shadows which were lost in the last cleaning had been recorded in all previous copies, including, sometimes, ones made during Michelangelo’s own lifetime. (See, for example, How to Take a Michelangelo Sibyl Apart, from Top to Toes, Frankenweenie – A Black and White Michelangelo for Our Times, and, Cutting Michelangelo Down to Size and Figs. 12-14 here.)
Above, Figs. 10 and 11: Here, we see a detail of Michelangelo’s Erythraean Sibyl before cleaning (top) and after cleaning (above). Once again, we see (in microcosm) the losses of shading and modelling that occurred throughout the ceiling. If we make careful comparative appraisals we can see the loss or break-up of actual brush-strokes. We can see that before restoration, the forms of the ear were more decisively drawn (note the black line that picked out the bottom of the ear lobe) and more sculpturally modelled. A straightforward cleaning of a dirty painting would enhance, not diminish, the values that had previously been visible even under dirt.
Above, top, Fig. 12; Above, centre, Fig. 13; Above, Fig. 14.
The above sequence of images of Michelangelo’s Jonah on the Sistine Chapel ceiling shows the continuity of features – note especially the shadow cast by Jonah’s left foot – that were recorded in an unbroken sequence from within Michelangelo’s lifetime until the last restoration. Thus, in Fig. 12 we see a wash drawing by Giulio Clovio which records in its bottom corners parts of two lunettes that Michelangelo had painted before 1512 but then had destroyed by 1534 to prepare the altar wall for his Last Judgement. It is therefore a record of how the figure appeared before the frescoes had become dirty and before any restorer had approached the ceiling. This single image refutes the testimony of the Vatican laboratory’s chemical analysis which was said to have established that Michelangelo had not painted the shadows. The shadows not only survived for centuries they were recorded in all copies and photographs of the figure up to the time of the last restoration. In Fig. 13 we see two engravings made in the early 19th century. In fig. 14 we see a photograph (on the left) showing the extent to which the shadows had survived until the last restoration, and one (on the right) taken after the restoration during which the shadows were removed.
Above, Fig. 15: Turner’s 1810 painting “Lowther Castle – Evening” which was given to the nation and presented to the Bowes Museum at Barnard Castle. As the Northern Echo has reported, on acquisition, the Bowes Museum decided to restore the painting. The museum’s conservation manager, John Old, carried out some “background work” and “a chemical analysis” and began the restoration which is visible to the public every Tuesday, Wednesday and Thursday. Like Philip Mould’s restorers (see Figs. 17 and 18), Mr Old began by cutting a rectangular “window” directly through the old varnish until paint was reached. This method of cleaning is widely encountered but is controversial within the field. It was strongly opposed, for example, by the influential and famously moderate or “minimalist” restorer Johannes Hell, for reasons that will be given in a future post.
In today’s picture restoration there is constant methodological churn. There are no agreed methods of cleaning – some restorers favour solvents; some favour soaps; some favour abrasives; others, lasers. Some advocate total and swift cleanings; some commend slow and partial ones. Some favour selective cleaning. There are no universally accepted codes of ethics, no strict rules of professional behaviour, there is no striking-off from professional registers. Despite frequently assumed quasi-medical airs and talk of diagnostics, patients and such, there is, as the painter Thomas Torak has regretted, no Hippocratic Oath to “do no harm”.
Above, Fig. 16: John Old at work, as shown in the The Journal of 26 December by which time many overlapping windows had been cut through the varnish. The Journal reports that “Although a chemical analysis was carried out” before work began, “it still turned out to be a bigger challenge than he expected as he discovered areas of paint loss probably caused by damp”. It is disturbing that neither chemical analysis nor close visual scrutiny – or background researches – identified the problem before work began: “Although we did a lot of scientific analysis you can never really tell what you’ll find until you start work”, Mr Old said. It is not reassuring that Old “retouched” the damaged area even before the cleaning was finished. Today, with varnish still to be removed when part of the picture has already been repainted, Old is taking a break from work “while further chemical analysis is undertaken to trace the different techniques used by Turner across the painting”. Given that the preliminary analysis failed to detect the surprise passages of damaged (and presumably repainted) work, how confident can we be at this point that further analysis will succeed in identifying all of Turner’s notoriously quixotic techniques on this painting?
With an artist like Turner, can it ever be sensible to begin by cutting windows quickly through sections of varnish, rather than by proceeding in a gradual and overall campaign to thin the varnish and, thereby, approach what is suspected to be the underlying paint surface with circumspection and retaining the option of holding back where necessary or desirable?
Above, Figs. 17 and 18: The dust wrappers of Philip Mould’s books of 1995 (left) and 2009 (right), both of which show rectangular windows cut sharply through discoloured varnish.
