Sistina Progress and Tate Transgressions

6 June 2014

The tide continues to run against supporters of the Vatican’s 1980s and 1990s restorations of Michelangelo’s Sistine Chapel frescoes, but it looks as if the National Gallery’s technical conservation division might be about to attempt a last-stand defence of the proclaimed “Gloriously Recovered Colours” that were said to have resurrected a “New Michelangelo”. An exhibition at the Gallery, Making Colour (June 18 to September 17), is to examine the stuff of pigments, in the course of which… Michelangelo is to be enthroned among the great colourists Titian, Turner and Matisse. The manoeuvre shows signs of back-firing.

The Times’ art critic Rachel Campbell-Johnston was healthily wary and alert to art world conservation politics when previewing the exhibition (“True colours: from Titian to Turner”, The Times, 31 May 2014):

“It is wilfully provocative to put a sculptor most famous for his pallid stone carvings on a list of the world’s greatest colourists. But his Sistine Chapel paintings – coming together as they do to create the single greatest pictorial scheme of the Italian High Renaissance – are among the most vibrant works of western art ever created. And after a recent and highly controversial restoration in which solvents were used to strip away half a millennium’s worth of accrued candle smoke and grime – and with it, many argue, the artist’s own shadowy subtleties – Michelangelo is being reassessed. Every book on this artist will have to be rewritten declare historians who marvel at the newly revealed drama of vivid colour. Others, however, remain not just sceptical but deeply dismayed at the irreversible damage that the cleaning has done.”

Even the restoration-friendly Art Newspaper carries seditious words on conservation and the Sistine Chapel in its current (June) issue. The spat that we reported between Bendor Grosvenor (“Art historian, dealer and broadcaster”, of the Philip Mould and Company gallery), and Martin Myrone (“Lead curator, pre-1800 British art at Tate Britain”), at last month’s Mellon Centre conference on connoisseurship and educated eyes, is re-run in the Art Newspaper under the heading: “Do we need a return to connoisseurship?” Dr Grosvenor’s latest comments on restoration and connoisseurship are, however, almost cryptically condensed. They read in full:

“I despair at seeing a picture over-cleaned through a conservator’s misunderstanding of how an artist worked, and the removal of an original glaze in the belief that it is either dirt or over-paint (the Sistine Chapel is the most depressing example of this).”

For the record, Dr Grosvenor’s Mellon Centre mea culpa of May 2nd was delivered as follows:

“And to show why I think that connoisseurship has such a valuable role to play in conservation, let me mention what is – let me end with what is probably the most single important painting in Western art history: Michelangelo’s Sistine Chapel ceiling. I recently went to Rome and saw the ceiling for the first time, and as I was standing underneath it with my binoculars, being jostled this way and that by the crowds, I am afraid I got a terrible shock. I always used to think that critics of the Sistine Chapel restoration were being slightly myopic, or a little bit obsessive, and that trained restorers surely at this level were infallible, and couldn’t possibly damage pictures. But how wrong I was! The Sistine Chapel has been subjected to the most brutal over-cleaning imaginable. I don’t mean the exposure of the bright colours which we see looking so nice here, which most people fixate on, but the actual removal, through simple abrasion with solvents and a rough sponge, of the crucial darks and shadows which gave the ceiling so much meaning and form. Though we don’t have time to go into the debate here as to whether Michelangelo worked a secco on the ceiling or purely in fresco it seems to me that the whole approach to the cleaning of the ceiling was fundamentally misunderstood. But my contention is that if the restorers had, in fact, been real trained connoisseurs of Michelangelo’s work and were not just pure technicians and had a feeling and an eye for how Michelangelo intended his pictures to work they might not have made the same mistakes. And I don’t think I can really make a greater example of why connoisseurship matters. Thank you very much.”

The now linked battles over art restoration and connoisseurship are intensifying. (We are intrigued to know what Dr Grosvenor thinks of the Philip Mould gallery’s own picture cleaning methods. We do know that even when restorers aim to remove just “varnish”, real paint often comes off in the wash – as seen at Figs. 12 and 13. Would the risks not be all the greater when restorers are removing what they take to be “re-paints” from pictures in a hunt for better work underneath?) The museum world’s phoney “Culture Wars” between a supposed but now mythic Art Establishment (look at the recent membership of the Royal Academy and its Summer Show banner “Discover the new; discover the now”) and the Tate and State-pampered, edgy, head-banging contemporary art sensationalists is masking a fundamental art world schism that shows signs of turning ugly. Dr Grosvenor’s ideologically opposite number at both the Mellon Centre conference and the Art Newspaper forum, was Dr Martin Myrone – who happens to have hit the headlines. Tate Britain is mounting an exhibition of British folk art (see “Tate Britain rejects ‘elitist’ Old Masters as Turner makes way for thatched king”, the Times, 5 June 2014). Tate’s press release declared “British Folk Art will include surprising and diverse examples of British folk art, from rustic leather toby jugs to brightly coloured ships’ figureheads. The imposing larger than life-size thatched figure of King Alfred created by master thatcher, Jesse Maycock, in 1960 is one of the exhibition’s highlights.”

News of this exhibition almost caught us off-guard: when Tate spokespeople witter about “diverse” and “surprising” things, we instinctively reach for our cultural pistols, so to speak. But for once, the artefacts clearly are of interest (see Fig. 11) and worthy of attention. The bone cockerel shown in the Times is, in its wit, force and verve of plastic articulation, the superior of the over-sized blue cockerel presently occupying the fourth plinth in Trafalgar Square – which itself is the best of a very long, very bad bunch of occupants. The straw man, likewise is, with its subtle, ominously Germaine Richier-like weight-shifting presence, more than an expressive sculptural match for, say, Sir Anthony Gormley, R. A.’s turgid “Angel of the North”. In short, we have no problem with the subject of the exhibition: quality is, as quality is found. No problem, that is, except this: the Tate is not parking this exhibition in Tate Modern’s vast halls or spinning it as an overdue and welcome blast against the enfeebled self-indulgence of today’s decayed fine art tradition. Instead, it treats this folk art as vindication of that very sector (because Tracey sews and Grayson potters) and is using it as yet another way of denigrating and humiliating odious, elitist Old Masters. (One more sign, perhaps, of the un-wisdom of permitting one man an unbroken, guaranteed-for-life, twenty-six years long reign of tenure at the Tate?)

Insofar as Dr Myrone’s dense sub-Marxian jargon in the Art Newspaper permits appraisal, it would seem that his antipathy to the notion and practice of connoisseurship is deep and visceral. As he puts it in the Art Newspaper:

“…Instead, contriving the resuscitation of connoisseurship on the basis that its worth is self-evident may be retrogressive, obscuring the stakes and investments actually brought into play as the different parties involved (academics, curators, dealers and so forth) establish their relative authority and their claims to public attention…Arguably, the only thing that now distinguishes connoisseurship as such is the element of economic and social purposefulness, its specific role as a way of talking about art and asserting aesthetic merit in terms which are readily translatable into economic value. The language of connoisseurship is simply more compliant to the needs of the market than other forms of historical discussion, which may be more open-ended and questioning, less certain about the judgement of value.

“Moreover, allowing the issues of authenticity and authorship to overshadow all the other issues and questions around historical works of art risks impoverishing our understanding and enjoyment of art’s rich histories and our ability to communicate this in genuinely open-minded, engaging and thought-provoking ways. There is nothing, I think, radical or outrageous in pointing out that connoisseurship has served to reinforce social difference and further material interests over history.There are numerous studies which testify to this. What would be absurd would be to claim that this has somehow stopped in the present age and that connoisseurship is now absolutely removed from struggles over cultural authority…”

What is so sad and alarming is that art professionals working in the most elevated art institutions should be so antipathetic to art as art. As for lucre, they are happy to pursue careers and draw salaries working among art as long as it can be made instrumental – serve some “enlightened” progressivist, consciousness-altering, society-levelling social force. This is sad because it is philistine. It fails to respond directly, unashamedly, unapologetically to art itself. It is dangerous because should such blinkered aversions gain an absolute upper hand, cultural repression would result. Dr Myrone is clearly a conscientious man with the interests of the common weal at heart. But if we were to deny contemplation of the highest, the best, and the most life-enriching art to all, we would gain nothing and simply add cultural and personal impoverishment to existing social ills.

This antipathy to connoisseurship must be defused. First, let us recognise that it really doesn’t necessarily come with snooty baggage or an eye on the financial main chance. That, at heart, it is a perfectly simple, decent and desirable matter; that it is comprised of nothing more odious than an ability to discern qualities that are of value. Second, that every art school lecturer used to recognise “the hand” of every student. We say “used to” because artistic hands are only evident when common cultural purposes are pursued through limited artistic means (as when all art students drew and drew from the same casts or figures). If scrunching paper and blinking lights count as art today then connoisseurship is already dead – and Dr Myrone can chill. He may, on the other hand, already be halfway to connoisseurship himself – in the Art Newspaper, he also writes:

“It is perfectly possible to talk about technique, authorship, authenticity and quality without recourse to the rubric of connoisseurship. Moreover, the application of skill in these various matters is part of the every day work of the art historian and curator, tending in practice to be rather modest and mundane. It is just part of the job.”

Well, which is it to be? If connoisseurship is being done routinely, albeit under a different name, what is the problem? And why should we not talk about the doing of it, on the assumption that some may be doing it better than others?

In art practice itself, every proper artist is a connoisseur, not least of his own work. Every teacher forms preferences and will see more of value in the productions of one student over another. That is connoisseurship in action. Nothing to be ashamed about. When teaching in art schools it is not unheard of to encounter a student from Eton or from the Old Kent Road. Proper professional concern for quality and talent puts the Old Etonian on a level playing field and at risk of being outclassed by the greater talent of someone from nowhere. Dr Myrone complains, as reported in the Times, “We have rested much more on the idea of a canon of great masters, a Hogarth-to-Turner story…it is a fairly narrow kind of canon. A select few artists have been elevated, but there is a whole world of making and physical production which is really exciting.” And so there is – but what humbug: narrow canons? How many working illustrators, film animators or car designers win Turner Prizes or get elected to the Royal Academy? Is everything really of equal value to the Tate? Are all avant gardists of the same merit? On what basis, then, are the Turner Prizes awarded? If someone scrubs a painting and features come away, as was the case with the group of lads holding a ladder at the top of Fig’s. 7 and 8, would it be a good and desirable thing if art historians lacked the critical visual ability to notice – or the courage to speak out? Dr Grosvenor has at last cottoned on to the menace – is Dr Myrone still not up to it? Has he not yet come across the excellent post on Grumpy Art Historian which carries this helpfuly clarifying comment:

“Why cannot the art historian emulate [the archaeologist] and treat all images simply as artefacts of a given culture? I think the answer is simple. Such pretended scientific objectivity would rapidly lead to the suicide of our subject. On a purely practical level the archaeologist is saved from the agony of selection by the relative scarcity of his evidence. We are in a very different position. Once we decided not to make any distinctions between painting ceilings or, for that matter, assembly halls, we would be so swamped with material that Michelangelo’s or Wren’s creations would be lost in an ever-swelling card index”

Above, top, Fig. 5: The Sistine Chapel ceiling as seen after cleaning in the 2006 Scala book The Vatican Museums ~ Masterpieces from the Incomparable Papal Collections. The book carries this statement-in-brief of the enduring official account of the restoration: “It took nine years from 1980 to 1989, for the restorers to rid the frescoes on the ceiling of the Sistine Chapel of the accumulated grime of centuries to recover the original bright colouring, allowing us to enjoy these extraordinary figures once more.”
Above, Fig. 6: A detail, as recorded in a large-scale lithograph of the entire ceiling that was printed in twenty-one colours on two sheets of paper. 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 stunning A history of Chromolithography as described in our previous post.)
The testimony of this large-scale work which faithfully recorded the Ceiling’s then chromatic and tonal relationships is immensely valuable. Partly because it shows all of Michelangelo’s upper walls and ceiling frescoes simultaneously on the same plane and without any perspectival distortion (and, thus, in a manner that was inconceivable photographically), but more especially because it captured the hierarchy of tones and colours which progressed from the darker more subdued lower sections (seen in this image in its outer parts) toward the brightly lit ‘windows’ which cut through the illusionistic architecture and permitted the biblical scenes to be set in the sky or out in the wider world. This single image gives the lie to the original claims of the restorers – and their once-numerous supporters – that the shading in Michelangelo’s frescoes had not been a deliberate artistic intention, but was simply the arbitrary consequence of accumulations of soot and varnish. That claim was always preposterous – but it explains why, even to this day, some supporters of the restoration cling to the once-confident and near-universal belief that the “transforming” (i.e. artistically devastating) effects of the cleaning constituted an almost God-given revelation. The ‘political’ need for this restoration to be defended at all costs has inflicted considerable theological collateral damage as well as immense artistic damage.
Above, Figs. 7 and 8: A section of the upper-right corner of Michelangelo’s Last Judgement wall, before cleaning (top) and after cleaning (above). Again, looking at the areas and the scale of the shading that was lost here, makes clear how absurd was the claim that Michelangelo had originally painted as as in the cleaned state at Fig. 8, and, then, centuries worth of grime had conspired to alter Michelangelo’s painting so as to bring it to the condition see at Fig. 7.

A RECENT RESTORATION “DISCOVERY”: WHAT COMES OFF IN THE VARNISH REMOVAL WASH
Above, Figs. 12 and 13: A painting – View of Scheveningen Sands, by Hendrick van Anthonissen – as seen (top) before “varnish removal” at the Hamilton Kerr Institute, the art conservation branch of the Fitzwilliam Museum, and after cleaning (above).
View of Scheveningen Sands is on permanent display in the Fitzwilliam Museum in the recently refurbished gallery of the Dutch Golden Age, which reopened on 3 June.
Cambridge University’s Varsity website reports that whilst removing the varnish from this painting, the restorer, postgraduate student Shan Kuang, discovered that “a figure started appearing standing directly on the horizon line [of the sea].” And then, soon after, the fin of the whale was discovered, being at first thought to be the sail of a ship. However, eventually, the body of the stranded whale was fully revealed…and another glorious restoration discovery and Good News Story had been made and announced to the world.
…AND, YET ANOTHER RESTORATION DISCOVERY:
“Paris Street; Rainy Day” – now not!
The Wall Street Journal reports that The Art Institute of Chicago’s six-month restoration of Gustave Caillebotte’s 1877 painting revealed surprises. A previous restoration left the sky “duller and more one-dimensional [sic]”. As a result of the varnish removal – and the removal of what was taken to be an earlier restorer’s repaint in the sky – curators now believe Caillebotte is likely to be viewed more as an Impressionist and less a traditional realist. Moreover, the restorer said that Caillebotte had not (as had been thought) depicted a generic rainy day in this bustling street scene near the Gare St. Lazare. Instead, he had had in mind “a precise moment right after the rain has stopped and the sun is trying to break through” — which is why everyone in the picture continues to walk around with umbrellas up. To the present restorer, this newly recovered state of the painting constitutes “the kind of specificity that was a hallmark of the Impressionists”. Another great conservation-led advance for scholarship, then.

The Twilight of a God: Virtual Reality in the Vatican

12 December 2013

It seems that there is to be yet another make-over at the Sistine Chapel. It seems that, for the Vatican, you can never have too much colour, or too bright a supply of lights – or too many paying visitors – in the Pope’s private chapel. It seems that aesthetics are now under the control of technicians and bean-counters. Michelangelo is to suffer further indignities. The recent falsification of his work by “restoration” is now to be artfully compounded by bespoke hi-tech boutique lighting.

On 7 November, the Times’ business section broke the news that the Sistine Chapel is about to be illuminated by no fewer than 7,000 new LED lights (by courtesy of technical wizards at Osram and EU Research funding). Their purpose is to “enhance” the experience for visitors (see Fig. 1, “Judgement day for a bright idea”). In the FT Weekend Magazine it is claimed that the 5m tourists who now pack into the chapel each year will “have a far better view” (Mind/Science: “Illumination: New Light on Michelangelo”, 30 November 2013). This is on the grounds that, while the present lighting creates a “low-contrast twilight that fails to bring out the colours in Michelangelo’s masterpiece”, the replacement will facilitate “a completely new diversity of colour”. This diversity is to be the product of artificially selective sources of lighting, quite unlike anything found in nature and unlike previous systems of artificial light used in churches and chapels.

There are two things wrong here. The first is that Michelangelo’s colours have already been forced chemically into a false chromatic intensity by the misconceived and radically intrusive restorations of the 1980s and early 1990s. As we have repeatedly demonstrated (see bottom right), the homogenised applications of solvents-saturated cleaning gels stripped away the artist’s own tonal modifications of colour and intensification of shadows, even though there was abundant evidence that this part of the frescoes was original work that had been recorded during the artist’s own lifetime and throughout the frescoes’ history. (On the aesthetically destructive impact of the cleaning method, see Figs. 3 and 4.) Second, this proposed attempt to flood the Chapel with artificial light constitutes a bizarre “own-goal” act of revisionism on the part of the Vatican.

That is, the defence offered at the time of the controversial restoration was that the new and startling colour effects (which many critics likened to Disney animation stills) had been calculated by Michelangelo himself so that his images would cut through the gloom of a smokey chapel. On that initial rationale there can be no aesthetic or historical justification today for flooding the Chapel with artificial stage-lighting that is to be ten times more powerful than the existing artificial lights.

In the December 1987 Apollo, the Vatican’s official spokesman/consultant on art historical matters, Prof. Kathleen Weil-Garris Brandt, conceded that the “transformation of Michelangelo’s mysterious dark frescoes, half visible but so familiar (at least from reproductions), into blazing, colouristic pyrotechnics… is attracting the most public attention and controversy.” Nonetheless, she insisted that Michelangelo had “modelled his forms by means of colour” – this, despite the fact that his contemporaries had been united in the contrary conviction that he had done so by his unprecedented powers of light and shade. One apologist declared in December 1987 that all previous Michelangelo scholarship had been prey to what he dubbed “the Darkness Fallacy and the Sculptural Fallacy”. It was further claimed that the revolutionary chemical excavation of the “New Michelangelo” was “one of the great revelations of our time” and that it required nothing less than the rewriting of art history.

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? If that seems inconceivable, let us turn the question round. Has there been in recent years any loss of chromatic intensity in the bare, stripped-down fresco surfaces that were left exposed for the first time in their history to the air-borne pollution of Rome? If not, why, as the FT reports, was it thought necessary to analyse Michelangelo’s surviving pigments so that each one of the 7,000 new lights might be individually attuned to a spectrum that suits the said, specific pigments precisely as and where they are encountered on the present ceiling – and in the present “twilight that fails to bring out the colours in Michelangelo’s masterpiece”?

This proposed adjustment of lights for the purpose of chromatic enhancement rather creepily resembles the use of projected light to simulate the original condition of colours that had faded in Rothko’s Harvard murals. The authors of a paper delivered at the 2011 Lisbon ICOM conference on this particular usage on modern paintings, concluded that theirs is: “A novel restoration technique that uses colored light from a digital projector to compensate for color alteration… To the authors’ knowledge, this approach has not been used previously for the restoration of paintings.” So we ask again: Has the Vatican been monitoring the colours of Michelangelo’s frescoes since the last restoration? If it has, have any changes and deteriorations been detected – and is this lighting system designed to compensate for them? Could the Vatican be attempting to launch by stealth what will be the world’s first non-secular virtual restoration?

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

April 1st 2011

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Above, Fig. 1: a detail from one of Michelangelo’s Sistine Chapel pendentives, “The Punishment of Haman”, containing, in its centre section, a repair made made by the painter Domenico Carnevale in 1566.
Above, Fig. 2: a diagram in which the parts of the figures of Esther and the king Ahasuerus that were repainted by Domenico Carnevale in 1566 are indicated by dotted lines in the centre section.
Above, Fig. 3: a detail showing, in the centre section, the arms of Esther as restored in 1566 by Domenico Carnevale.
Above, Fig. 4: the left-hand section of Michelangelo’s pendentive depicting “The Punishment of Haman”, as seen before the last restoration. Note the close conformity between the tonal/shadowy zone occupied by the figures as seen here and that recorded in the engraving of 1796 by Domenic Cunego in Fig. 6.
Above, Fig. 5: the left-hand section of the pendentive “The Punishment of Haman”, before cleaning.
Above, Fig. 6: the pendentive “The Punishment of Haman”, as engraved in 1796 by Domenic Cunego. Note particularly, here, the skilful placement of the darkest tones in the three corners of the pendentive. And, the masterly use of light and shade to articulate the roles of the principal and secondary figures. Pulling the (very sketchily drawn) group at the left out of their original shadow, as occurred in the recent restoration, did them no favours and did great violence to the disposition of Michelangelo’s own pictorial values. Few will doubt that Michelangelo had intended to place the greatest possible emphasis on his central crucified figure – an invention which constituted an astonishing tour de force in its day by means of the violent planar opposition of the knees, which are parallel with the picture plane, to that of the hands, which contrarily advance upon it at a near right angle. This great figural innovation is emphasised by the artist in the similarly acute foreshortening of the wall to the right of Haman.
Above, Fig. 7: the figures of Esther and King Ahasuerus, after restoration.
Above, Fig. 8: Michelangelo’s depiction of God in “The Separation of the Earth from the Waters”, as engraved by Domenico Cunego, 1772-1780. Note the remarkable similarity between the shading of God’d left arm and that reproduced by Carnevale in his treatment of Esther’s arms.
Above, Fig. 9: Michelangelo’s “The Separation of the Earth from the Waters”, as engraved by Attilio Palombi in 1887.
Above, Fig. 10: The left hand of God in “The Separation of the Earth from the Waters”, after the recent cleaning. The diagonal crack entering at the top, centre, bounds the area of Carnevale’s restoration of the hand and part of the cuff, made in accordance with the tonal values found on the figure in 1566.

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