Michelangelo’s disintegrating frescoes
As we predicted at the time of the last restoration of the Sistine chapel ceiling, by removing all of the glue-painting applied by Michelangelo to finish off and heighten the effects of his frescoes, the Vatican’s restorers exposed the bare fresco remains for the first time in their history to new dangers from the atmospheric pollution that is exacerbated by huge numbers of paying visitors.
Then, 2 million visitors entered the chapel every year. Now, that figure is 6 million.The Vatican has been carrying out secret attempts to remove disfiguring calcium deposits building up over the remains of Michelangelo’s painting. These deposits are caused when moisture given off by tourists and air-borne pollutants are absorbed by the plaster. This now-acknowledged process will also activate, as we specifically contended, the remnants of the cleaning agents (sodium and ammonia) that were washed into the frescoes during the rinse cycles of their last so-called restoration and conservation treatments. At the time, the use of the ferociously aggressive cleaning agent AB 57 was justified by the Vatican on the grounds that it was necessary to remove, among other things…ordinary solvent-resistant calcium deposits that had built up over the centuries in parts of the ceiling exposed to leaks in the roof.
Then, the Vatican promised that special air-conditioning systems would protect the newly exposed fresco surfaces in perpetuity. That system had failed even before the Vatican recently celebrated the twentieth anniversary of the end of the last restorations of Michelangelo’s paintings. Today, as the new physical threat is seen to be turning the frescoes white, the Vatican promises new, improved air conditioning units (from the same firm). To counter the new pale appearance, the Vatican recently installed thousands of LED lights, each individually attuned to heighten the colours in Michelangelo’s painting. Michelangelo’s now twice-injured painting has been left a colourised but still lucrative wreck – and an EU-funded (EUR 867 000) showcase (“This made the Vatican City’s Sistine Chapel the ideal venue for LED4ART”) for a company that shows in its advertisements that it has no idea what the Sistine Chapel looks like.
We said at the time that the restoration constituted a crime against art. Now, the Vatican promises to limit the numbers of visitors inside the chapel to 2,000 at any one time. But that means allowing a crowd as big as a full capacity audience at the Royal Opera House in Covent Garden, London, to pack into the small chapel all day long. The Vatican’s administrators – who have known of the present problems since 2010 – now concede that the glue coatings (that were in truth Michelangelo’s own final painted adjustments) had served as a protective barrier against all air-borne pollutants. The tills will continue to ring. Art lovers remain weeping. Shame on the Vatican’s administrators.

UPDATE: 16 November 2014
While the Vatican now admits the hitherto concealed fact of the damage that is being caused to Michelangelo’s frescoes by the massive increase of tourist numbers, it remains in denial about the destruction during the last restoration of the final a secco adjustments that Michelangelo had made to those frescoes. That autograph last-stage painting – which was observed and described with perfect, detailed clarity by the painter Charles Heath Wilson in the 1881 (second) edition of his book Life and Works of Michelangelo Buonarroti – is characterised, preposterously, and against the evidence of all contemporary and subsequent copies of the Sistine ceiling, as consisting of “centuries of built-up candle wax, dirt and smoke”, as if such substances might somehow have disported themselves along the lines of Michelangelo’s design so as to reinforce his modelling and depict shadows cast by his figures. This latest apologia is carried in an Associated Press article “Sistine Chapel frescoes turning white ~ Humidity, tourists’ CO2 to blame”.
A paperback facsimile of a 1923 edition of Wilson’s milestone book (in which he describes his close examination of the ceiling on a special portable scaffold) is now available. It is time for the Vatican to acknowledge that Michelangelo had indeed finished his frescoes with secco painting, and that its curators, restorers and conservation scientists had blundered badly and inexplicably when, having judged Michelangelo’s specific, purposive pictorial enhancements and modifications to be nothing other than arbitrary accumulations of polluting material, removed it – and, thereby, exposed the lime plaster surfaces of the frescoes to their present dangers. That initial error and the subsequent falsification of art history that was made on its back, have both now been maintained for two decades.
How the Metropolitan Museum of Art gets hold of the world’s most precious and vulnerable treasures
An exhibition of stained glass that has been removed from “England’s historic Canterbury Cathedral” has arrived at the Metropolitan Museum, New York, after being shown at the Getty Museum in California. The show (“Radiant Light: Stained Glass from Canterbury Cathedral at the Cloisters”) is comprised of six whole windows from the clerestory of the cathedral’s choir, east transepts, and Trinity Chapel. These single monumental seated figures anticipate in their grandeur and gravity the prophets depicted by Michelangelo on the Sistine Chapel ceiling. They are the only surviving parts of an original cycle of eighty-six ancestors of Christ, once one of the most comprehensive stained-glass cycles known in art history. (See Figs. 1 – 5.)
The Met boasts that this exhibition of “Masterpieces of Romanesque art…represents the first time they have left the cathedral precincts since their creation in 1178-80”. Who, then, gave permission for the loan of such fragile, precious and architecturally integral material?
The New York Times says of the exhibition that it “Seemed to have been beamed down from on high”, when it undoubtedly had been flown and vibrated down from on high in an aeroplane. The museum world repeatedly offers assurances that modern air transport is perfectly safe for moving treasures around, even though, as the world now well appreciates, aeroplanes do sometimes crash or disappear. Aside from in-flight hazards, works of art get taken by roads to and from airports where they disappear from curatorial view and supervision into high-security cargo depots, sometimes being injured by forklift trucks, and the like, in the process.
The bureaucrats of “Glasgow Life” who administer Glasgow’s museums recently argued (successfully) in Scotland’s Parliament that, as Sir William Burrell had permitted loans from his bequeathed collection within Britain, and as the most dangerous part of lending works is dismantling them in one place and reassembling them in another, overturning his prohibition on foreign travels would be no more dangerous than moving works within Britain. The bureaucrats were similarly successful in overturning Burrell’s prohibition on lending certain categories of fragile works at all, within or outside Britain, such as glass, tapestries and pastels, by arguing that advances in modern packaging skills meant that even the most fragile work could now safely be moved subject to prior conservation examinations.
With the Burrell Collection we know precisely who will carry responsibility for any future travel injuries or losses but with the Canterbury treasures, who at the Cathedral (or in the Church) would take responsibility were these windows to be harmed or lost during their trans-Atlantic travels?
Were these windows insured for their travels, and, if so, what price was put on them?
Has the Church received any payment for this loan, and, if so, how much?
Were the six windows which travelled from London to California and from California to New York flown in separate aeroplanes – as were the three (of ten) gilded panels from Ghiberti’s Florence Baptistery doors (dubbed “The Gates of Paradise” by Michelangelo) when they were sent from Florence to Atlanta; from Atlanta to Chicago; from Chicago to the Metropolitan Museum, New York; from New York to Seattle; and, finally, from Seattle back to Florence? (See Figs. 6 and 7.)
The Metropolitan Museum seems to be a common destination point on many of the most ambitious and hazardous inter-continental tours of art (it will receive the current Tate show of Matisse’s monumental, previously too-fragile to loan, cut-out paper works). In the case of the Burrell Collection even before the Scottish Parliament had heard all the evidence arrangements for an international tour of works were in motion. On 10 September 2013, Joan McAlpine, SNP, the Chair (“Convener”) of the scrutinising Parliamentary committee, disclosed in The Scotsman that “Sir Angus Grossart was giving some hints [the day before, during evidence to the committee’s first session] of the kind of people he’s been speaking to in terms of a world tour…I know they’re talking to the Met in New York, and from the point of view of the people at Glasgow Life, that’s an opportunity to enhance the reputation of the collection, the city and Scotland.”
Crucially, Grossart’s moves were not being made under the aegis of the Burrell Trustees, who are charged with protecting the collection according to the terms of Burrell’s fabulously generous bequest (the 8,000 bequeathed works still constitute the largest gift ever made to a city), but by “Glasgow Renaissance”, an interceding body set up by Glasgow Life expressly to “oversee the Burrell Collection’s immediate future”, advise on the refurbishment of the leaking building which has suffered decades of neglect, and to facilitate the fund-raising, profile-heightening international tour of key works. Sir Angus Grossart, a member of Glasgow Life’s board of directors is the appointed chair of Burrell Renaissance.
In January 2013 it was reported (Herald Scotland) that the first, six months-long stop of the tour would be at the British Museum, whose director, Neil MacGregor, had been co-opted by Glasgow Life to serve on Burrell Renaissance (– as had been his fellow Glaswegian, Lord Kerr, the deputy chairman of Scottish Power). Grossart claimed in evidence given to the Scottish Parliament’s Burrell committee that no conflict of interest existed because no other venue in London had been thought appropriate to receive Burrell works – which is to say, not the Victoria and Albert Museum; not the Royal Academy; nor even the Hayward Gallery where an exhibition “Treasures from the Burrell Collection” was mounted in 1975.
When we appeared for ArtWatch UK as one of only two opposing witnesses before the Scottish Parliamentary committee (the other being Jeremy Warren of the Wallace Collection), we pointed out that the Metropolitan Museum’s present director, Thomas Campbell, had said of a major exhibition he had organised, “No one but the Met could have pulled off the exhibition of Renaissance tapestries we had a few years ago…We bribed and cajoled and twisted the arms of institutions around the world – well, we didn’t bribe of course – but politically it was very complicated negotiating the loan of these objects, which came from the British Royal Collection, the Louvre, the Hermitage, the Vatican and were just all absolute masterpieces.” (“Museum: Behind the Scenes at the Metropolitan Museum of Art”, Danny Danziger, 2007, p.40.)
It will now be greatly less complicated for Burrell’s fragile glass, tapestries, lace and pastels to be sent to the Metropolitan Museum – or anywhere else. Where Jeremy Warren of the Wallace Collection had testified “It is disingenuous to suggest that when one moves a 500-year-old tapestry from one country to another – perhaps taking it across the Atlantic – one is not shortening its life”, Councillor Archie Graham, Glasgow Council’s deputy Leader and the chairperson of Glasgow Life, thrilled at the prospect of “unlock[ing] the potential of this outstanding collection” and of being able thereby to “realise the full benefits of his gift.” We were not surprised to read Jackie Wullschlager’s report in the Financial Times (“Scottish independence”, 5/6 April 2014) that within months of overturning Burrell’s terms of bequest, a themed exhibition of works from within the collection (“Bellini to Boudin: Five Centuries of Painting in the Burrell Collection”) should open with all of Degas’s “glorious, delicate, light-sensitive” pastels shown in their entirety for the first time in a gallery in which water was dripping from the still unfixed roof “the day before” the show opened – that is to say, opened while on the watch of co-opted art world big-wig guarantors, the likes of Sir Angus Grossart and Mr Neil MacGregor. We did not, however, expect, when opposing the attempt to harvest the benefits of a collection bequeathed to the city of Glasgow, so soon to see the Church of England recklessly playing the same value-harvesting game with an irreplaceable part of the fabric of a cathedral and of our national heritage.

The Twilight of a God: Virtual Reality in the Vatican
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 1: David Hockney, an art historian and an x-ray photograph
It was recently claimed that “fresh insight” gained on Caravaggio’s painting technique supports David Hockney’s theory that the artist used a primitive form of photography to create his paintings (“Exhibition sheds new light on the art of Caravaggio”, Daily Telegraph report, March 11th). Diagrams, mirrors and light boxes displayed in an exhibition at the Palazzo Venezia in Rome, were said to “show” that Caravaggio “may indeed have” used a camera obscura to project figures on to a canvas so that they might be painted directly, with “extraordinary realism” and without any need for designs or preliminary studies. Showing that someone may have done something cuts no ice when logic, logistics and the laws of art all combine to testify against the Hockney hypothesis.
“Insight” itself is a weasel term and is not the same thing as evidence. The art historian supporting Hockney’s thesis, Dr John Spike, offered the observation that “Gallileo was developing the telescope and they [artists] were all fascinated by optics” as if by way of some circumstantial corroboration. Whether or not they were so fascinated, we should note the absence of evidence and consider the logistical difficulties that they would have faced if attempting to work on the basis of the Hockney Hypothesis.
Are we really to suppose that all the figures and animals, and babies, and flying angels, writhing serpents, crucified men and beheaded victims depicted in Caravaggio’s paintings in arrested moments of extremis, were actually copied directly, literally, from life? More specifically, are we to suppose that various combinations of human, bestial and divine creatures were first assembled and then simultaneously posed in full costume for as long as it took the artist to convert their projected photographic image into his painted pictures? (See illustrations on the right.)
Or should we believe that each figure was individually copied down, in full costume, exactly as seen when projected through a pinhole onto a wall in a darkened room? If so, was each painted figure subsequently “overlapped” and partly obliterated by the next in the sequence? Is there any material evidence of such overlaps? If not, we would have to assume that Caravaggio painted directly onto only that part of the projected image that would remain visible when the next figure was copied in. Timing is an important separate consideration: whether the models were depicted in entire groups or individually, how long would they have been expected to hold their usually animated and dramatically expressive poses (see right) in a compositionally perfect position in relation to other figures not yet posed or painted?
There is another crucial consideration: were Caravaggio’s famously dramatic and theatrical lighting effects copied directly from nature onto the canvas via an image of a multi-figure tableau projected through a pinhole? Consider the exponentially increasing practical difficulties an artist would have to overcome when attempting to work in such fashion. Caravaggio would not only have had to paint at speed to avoid his models wearying and slipping out of pose, he would have had to have done so at a speed that would not allow the brilliant light source illuminating his figures to move – and to have done so when working not in front of his painting but to the side of the image projected upon it so as not to block it with his own shadow. Has any artist in history so handicapped his own labours?
Would the light source deployed on Caravaggio’s frozen models have been the sun? If so, at what time of the day did he work? At noon, with the sun’s all-bleaching brilliant light at its zenith, producing unhelpfully top-lit figures? Or in the mornings and evenings when low, acutely angled, less bright but faster moving and changing? Did Caravaggio not only anticipate photography, but Impressionism too? Or, would his groups have been lit for long periods by a fixed battery of brilliant theatrical lamps?
When it is claimed that Caravaggio had achieved the extraordinary realism of his paintings 200 years in advance of the invention of the camera, on the same logic it should further be claimed that he anticipated and emulated the achievements of the cinema. It took the full resources of modern cinema and means of lighting for Luis Bunuel to be able to compose and momentarily arrest a multi-figured tableau in mimicry of Leonardo’s The Last Supper in his film Viridiana. Is there any evidence that such human and technical resources were available to Caravaggio? Is it believed that Caravaggio had invariably worked in this manner? Or that he did so on some occasions but not others? Has any material evidence been found in Caravaggio’s paintings that reflects such radically different patterns of working methods?
The real problem with the Hockney thesis, however, is not the absence of supporting evidence but the existence of contra-evidence. The Telegraph report is illustrated by a photograph of Caravaggio’s The Calling of St Matthew, and by an x-ray photograph of the two figures at the picture’s right-hand side. Those photographs (see above right) constitute a material record of both the paint that is visible to the human eye and the hidden earlier underlying painting. The caption claims that “x-ray analysis shows the style of the artist and supports the idea that he used a primitive form of photography in his work”. It is hard to see how this might be so. X-rays are notoriously difficult images to read with confidence because while they show all the successive states of a painting simultaneously they do not pick up all pigments and materials equally.
Nonetheless, the x-ray photograph that is shown adjacent to the two figures helpfully permits direct visual comparisons. The most striking feature is that the underlying paintwork exposed in the x-ray is not identical with the paintwork that is visible to the human eye. Had Caravaggio worked in the manner being claimed, an x-ray would reveal no differences – no revisions, no “pentimenti”, nothing other than what was already visible on the picture’s surface. But the x-ray evidence here is doubly injurious. Firstly, it shows major changes to the pose of the figures – Christ’s raised arm is higher in the x-ray than in the painting while, conversely, his hand droops dramatically. Secondly, the image is sufficiently intelligible to establish major discrepancies of artistic style.
In the space of the figure (St Peter) standing in front of Christ, the type of drapery seen in the x-ray photograph is manifestly different from that now seen in the visible paint above it. One observer (Giorgio Bonsanti) attributed the underlying drapery, on the basis of an earlier x-ray, to the figure of Christ – see right. Certainly as drapery it is greatly more accomplished artistically – more “Raphael-esque” – than the comparatively stiff, angular, “bent-tin” draped material seen on the St Peter. Most damagingly of all, this underlying painted drapery is not just finer it is of a type found only in art and never in nature. It is not some literal mechanical transcription of an actual draped garment, but a conjuring of spirited flowing, wind-filled forms that arc around the body and derive from the laws of drapery that were first understood and devised by the God-like artists of antiquity and then later rediscovered and emulated by the greatest artists of the Italian Renaissance. The living sculpture drapery revealed by the x-ray could not have been taken down from a static figure because it was an invention, a product of art and imagination that served the great powers of composition, design and expression – it conferred grandeur, grace and dynamism to the theatrical stage-right entrance of Christ. We might reasonably agree with Giorgio Bonsanti (see right) that Caravaggio, having first created this great glory, then opted to suppress his own magnificence of drapery so as to have the secondary, Christ-obscuring figure of St Peter serve as a dull mundanely reproachful foil to the wealthily and vibrantly attired group of figures to his left. On the basis of this clear hard embodiment of artistically purposive thought and revision – to the point of artistic sacrifice – it can hardly be concluded other than that Caravaggio was a great inventive, self-critical self-revising showman of an artist and not some secretive shortcut-taking literalist.
