Art’s Toxic Assets and a Crisis of Connoisseurship

30 September 2014

“Buy land”, Mark Twain advised, “they’re not making it anymore”. This logic ought to apply to the old masters but does not. Land makes sound investment not only because of its scarcity and its potential for development but because, in law-abiding societies, it comes fixed with legally defendable boundaries. Karl Marx, plundering English classical economists, held that all value is unlocked by human labour – but all labour does not generate equal values. In given periods and places all painters work pretty much with the same materials but their artistic transformations of those materials are various and unequal in accomplishment and merit. Such differences drive reputations and hence the market value of artists’ works but they do so in ways that are intrinsically problematic.

Artists’ reputations may or may not endure. With many surviving works the identities of authors are either not securely established or entirely unknown. In such cases paintings are appraised and then attributed to particular artists or schools. Attributions, however, are neither guaranteed nor immutable. They are made on mixtures of professional judgement, artistic appraisal, art critical conjecture and, sometimes, wishful thinking or deceiving intent. They remain open to revision, challenge, manipulation or abuse. The experts who make attributions exist in professional rivalry with one another (sometimes with vehemence) and while their disagreements are signs of art critical health, a consequence is that legal guarantees for attributions are untenable and non-existent, as some buyers later discover to their costs. Buyers are advised in the small print to beware and to proceed on their own judgement. With art, as we recently pointed out (see Endnote 1) it can be safer to buy a second-hand car than an old master painting (- and few people would dream of buying a house without legal searches and a structural survey.)

“Scientific” red herrings

In recent years attempts have been made to impart quasi-legal assurances to attributions by appealing to the authority of supposedly “scientifically verifiable” technical proofs. The exercise is vain and, technically, philistine: by its very nature, art is not reducible to scientifically quantifiable component parts. The technical evidence cult reflects a collapse of confidence in powers of connoisseurship on the one hand and a grab for cultural and institutional power by technocrats and bureaucrats on the other. The new hybrid discipline “Technical Art History” in which restorers, conservation scientists and curators pool expertises in attempt to arrive at professionally impregnable positions, has proved pernicious. Art-politically, this united front seeks to neutralise all charges of art critical and methodological failure with professional mystification and displacement activities – by fostering a “closed-shop” mentality and claiming that its mysteries are beyond the reach of any outsiders [2]. The new technocrats insufficiently appreciate that paintings are no more and no less than the products of artists who, working by brain, eye and hand, fix values and the relationships between values so as to produce specific and unique artistic effects that can be comprehended by others using eyes and minds in response. In the visual arts the visual should remain paramount – what you see is what it is about. Art loving viewers and professional art experts alike might be said to have duties of appropriate response to art itself and not to its shadows and encumbrances. It is the optically perceived quality of artists’ artefacts that drives reputations and market values. Understanding art is not the same thing as poking and poring over the component parts of its fabric – let alone presuming, as “restorers” (or now, “conservators”) perpetually do, to undo and redo its features at regular intervals. What matters is what you see, not what might be said or thought to lie under the surface.

Managing lapses of connoisseurship

This is not, of course, to say that technical examinations can serve no purposes. Rather, it is to say that in matters of art attribution and appreciation technical examinations of the physical composition of works might supplement informed visual appraisals but they cannot stand in lieu of them. Nor can the supposedly disinterested and neutral character of technical examinations themselves be taken at face value. In practice, with every technical investigation and its resulting “findings”, someone, some institution, some interest group, has commissioned/conducted the exercise and controlled its dissemination. Paintings in powerful institutionally-protected locations (particularly major museum) can be afforded dispensations from otherwise injurious findings [2]. It sometimes seems that just as banks are now too big to be allowed to fail, so big museum attributions cannot be allowed to fall, whatever evidence and arguments accumulate against them [3], for fear of undermining public, political and art market confidence.

Follow the money and look at the drawings

Concerning the frequency of art world upgrades, it would seem easier to grow old master drawings than paintings. Where only 250 sheets of drawings were attributed to Michelangelo in the 1960s, today that oeuvre has been expanded to over 600 sheets. Although drawings do not command the high prices of paintings they can greatly assist their attributions. In the late 1920s a firm of antiquarian dealers in Holland, R.W.P. de Vries of Amsterdam, sold a number of old master drawings some of which have ended in museums, and two of which concern us here (Figs. 1 and 2). Neither of these had a provenance (i.e. a proven history of previous ownership). Both had simply materialised in the dealers’ hands with old master attributions. The first sold in 1927 for 26 florins (guilders), some € 235.80 at today’s values. The second sold two years later for 750 florins, some €6,801.91 today. The first was attributed to van Dyck, the second to Veronese. Neither attribution survived and the original perplexing ratio of value between them (which approached thirty to one) has reversed dramatically.

The Veronese attribution crashed in 1984 when Richard Cocke published his catalogue raisonné Veronese’s Drawings and dismissed the drawing with the single (apt) sentence: “The heavy forceful cross-hatching in the drapery and the forms of the head and hands have nothing to do with Veronese.” That drawing sold in 1991 at Christie’s for £7,000 as “attributed to Agostino Carracci”. In contrast, the former van Dyck drawing morphed into the work that sold at Christie’s on July 10th as an autograph Rubens ink sketch for a world record Rubens drawing price of £3,218,500. The former “van Dyck” has thus enjoyed a 14,000-fold increase of value since 1927.

The extraordinary success of the van Dyck that is now a Rubens was due only in part to Christie’s masterful promotion. It was very much on the strength of its current art-historical position that the drawing was drum-rolled as the starred lot in a sale of part of the prestigious I. Q. van Regteren Altena drawings collection. Most helpfully of all, the drawing was precisely characterised as Rubens’s “first thought” preparatory ink sketch for the National Gallery’s Samson and Delilah painting (Fig. 4). Notwithstanding its anomalous traits (see our previous post), its artistic shortcomings and its dubious provenance, the drawing remains bolstered by its crucial allotted role in a sequence of three Samson and Delilahs, two of which have been acquired by museums (Figs. 3 & 4). Although Christie’s July 10 sale realised more than twice its highest estimates and broke many records for individual artists, only one of the top ten works went to an art gallery or museum. Two were sold on to the trade. Seven, including the Samson and Delilah drawing, went to anonymous individuals.

Making four Rubens’s

Christie’s catalogue entry burnishes the drawing’s pedigree with upbeat optimism. It is said for example: “When I. Q. van Regteren Altena bought the drawing in 1927, he listed it in his inventory under its traditional attribution to Sir Anthony van Dyck (1599-1641). That attribution also accounts for an earlier owner’s inscription of the letters ‘V.D.’ in the lower left corner.” What traditional attribution? Which earlier owners? Christie’s account of the provenance begins: “with R.W.P. de Vries Amsterdam; from whom purchased by I.Q. van Regteren Altena on 20 December 1927 for 26 guilders (‘387.t. A. v. Dijck. Samson & Delilah’)”. And that is all. There had been no previous owners and no evidence exists of any “traditional” reception as a van Dyck – or anything. Any suppositions aside, all that can safely be said is that this drawing emerged from nowhere at a time when forgery was rife and the art world suffered from what Bernard Berenson [!] described as “the universal tendency to ascribe a given work of art to the greatest artist to whom wishful thinking and excited imagination can ascribe it.” (“Essays in Appreciation”, 1958, p. 95.)

Christie’s entry continues: “With the emergence of the finished painting and the connected oil sketch the drawing’s significance rapidly became apparent.” There was no rapidity and the claimed significance is mythic. The supposed second stage oil sketch or modello did not appear until 1966. The claim that, “The picture of Samson and Delilah was only rediscovered in 1929”, also misleads. The painting was not “rediscovered” as a Rubens. It had never been a Rubens. When it appeared in 1929 it was, just like the ink drawing three years earlier, without provenance and it was not judged a Rubens by its German dealers, Van Diemen and Benedict, who were offering it as a Honthorst. It was later upgraded to Rubens in a certificate of authenticity by Dr Ludwig Burchard and it then sold in 1930 to August Neurburg, a German tobacco magnate.

Burchard was a leading Rubens scholar, but today his attributions have a notoriously poor record [4]. Far from the ink drawing being corroborated as a first stage sketch by the arrival of the painting, Burchard had upgraded the painting on the authority of the drawing which he had himself upgraded to Rubens in 1926. In Christie’s catalogue the drawing’s “Literature” begins with Burchard’s attribution: “L. Burchard, ‘Die Skizzen des jungen Rubens’ in Sitzungsberichte der Kunstgeschichtlichen Gesellschaft, Berlin, 8 October 1926, p. 30, no. 2.” At that date no one had previously owned or discussed the work. Burchard thus upgraded a drawing that had never been exhibited and was in a dealer’s hands without any provenance. Notwithstanding his claims on behalf of the drawing, in 1927 both the dealer selling and the collector buying still held it to be a van Dyck.

When the modello eventually appeared in 1966 it had no provenance. Its history consisted of a hearsay account (from the anonymous lady vendor) of an ancestor said to have bought the work for a few shillings in an antique shop in York during the 1930s because she liked the frame. This supposed Rubens oil sketch had been painted on a support that is found in none of the artist’s oil sketches – on a soft, conifer wood, not on his customary oak panel. Its appearance was, for a Rubens oil sketch, disturbingly close in design and effects to those of both the ink drawing and the finished painting (see Figs. 2, 3 and 4). Its arrival completed an unicum in Rubens’ oeuvre: a suite of stages of work without evidence of development. Notwithstanding that problem, the modello on the wrong wood was given to Rubens by Christie’s themselves, to join the company of a panel painting whose back, it later emerged, had disappeared in an operation for which no one acknowledged responsibility, and a drawing whose back was concealed by being pasted onto a second sheet even though it bore drawing itself. The modello sold to a London gallery for £24,000, going to a private collector before passing through Agnews to the Cincinnati Art Museum in 1972. The last of the trio to emerge, this technically problematic work-without-provenance was the first to achieve museum status. At some point, pieces of wood were removed from its sides (creating a closer compositional alignment with what is now the National Gallery painting) and, at another, the Cincinnati museum claimed the panel to be oak. Presently the wood is not identified, the work being described as on “panel”.

Why? Why? Why? Delilah?

In July 1980, the supposed third stage, the Samson and Delilah painting, was sold by Neurburg’s heirs through Christie’s to Agnews, acting on behalf of the National Gallery, for a then Rubens world record price of £2.53m. In 2002, with two parts of the Samson and Delilah trio now secure in museums and the third in a respected private collection, Sotheby’s sold a painting, The Massacre of the Innocents (see Fig. 13), as an autograph Rubens on the back of its perceived shared characteristics and collections history with the National Gallery’s Samson and Delilah for £49.5m, to Lord (Kenneth) Thompson. Even though those paintings are riddled with problems (see “Is this really a Rubens?” Michael Daley, Art Review, July/August 1997, and “Is this a Rubens?” Michael Daley, Jackdaw, October 2002), and the Samson and Delilah had been challenged for over a decade [5], the price was an outright old masters’ world record. Thompson loaned the Massacre to the National Gallery and then bequeathed it to the Art Gallery of Ontario, Toronto, thereby making it publicly available and greatly enhancing its pedigree. Thus, today, three high valued well-placed but individually problematic museum Rubens’s owe their positions to a belated acceptance of Burchard’s initial attribution of what is still a privately (but now anonymously) owned ink drawing.

Who cut Samson’s toes?

The reason why all of these subsequent Rubens upgrades rest on the authority of this ink drawing is because of a glaringly anomalous feature in the National Gallery painting – the fact that the toes of Samson’s right foot are cropped by the edge of the picture. This was not because the panel had been trimmed at some point. Rather, it is because the painting simply stops disturbingly, inexplicably, at the beginning of the toes. Thus, without the drawing’s seeming testimony that Rubens had planned to crop Samson’s toes by cropping his own initial design within a precisely drawn ruled box that anticipated (even before he had executed an oil sketch) the final format of what is now the National Gallery painting, that painting could never have been attributed to him. This is so for reasons that are implicit in Burchard’s 1930 certificate of authenticity. It read:

“The photographed painting on the other page is one of Peter Paul Rubens’ major works from the time of the master’s return from Italy. It must have been painted in 1609 or 1610. With Rubens’ agreement, Jacob Matham reproduced the painting with a copper engraving around 1615. As witnessed by the inscription of the painting, the picture at that time was in the possession of Antwerp mayor Nicolas Rockox. Indeed, the inventory of Nic. Rockox’ estate, dated 19 Dec. 1640, lists the picture as “Eene schilderne…(Annales de l’Academie d’Archaeologie de Belgique, Anvers 1881, p. 437). On pp. 143-44 in vol. I of 1886, the five-volume catalogue of Rubens’ work by Max Rooses, the painting is described in detail as number 115, based on the Matham engraving and mentioning the Rockox inventory. The picture itself remained as unknown to Rooses as to all literature since. It is further notable that a picture of an interior by Frans Francken (Pinakothek Munchen No 720), which appeared to be of mayor Rockox’s living room, showing the painting in pride of place above the mantelpiece, while in an adjoining room is the picture of the “Doubting Thomas” which we know Rubens painted for Rockox. According to S. Hartveld of Antwerp, the room with the mantelpiece exists even today in the Kaiserstraat in Antwerp where Frau Gruter-Van der Linden now lives in the Rockox house. A sketch for the Samson picture (pen, varnished, 16.4 x 16.2) is in Amsterdam in the collection of Mr J.Q. Regteren, Altena. The picture is in a remarkably good state of preservation, with even the back of the panel in its original condition.” [By courtesy of the National Gallery Archives Department.]

Note, even as Burchard asserts that this is the original painting of the subject that Rubens is known to have made shortly after 1608, he acknowledges that the original painting itself had universally been understood to have been lost since 1641. (To this day, despite detailed and sustained searches, nothing connects the present version to the original painting.) Crucially, Burchard also acknowledges that the appearance of the original Samson and Delilah had been recorded in two contemporary copies, one of which had been supervised by Rubens. Both of these copies by two artists who likely worked decades apart, testify that Samson’s original right foot had not been (improbably) cropped at the toes, as in the National Gallery version, but had originally been painted intact and set comfortably inside the composition and consistently with the artist’s known manner. See, for example, the almost contemporary, probably pendant (and near mirror-image compositional group) Cimon and Pero – “Roman Charity”, at Fig. 9.

A perplexing silence

It was in defiance of such hard historical testimony that Burchard claimed his own upgraded ink drawing to be not only by Rubens but, specifically, to be his preliminary sketch for the former Honthorst painting that is now in the National Gallery. When attributing that painting to Rubens Burchard executed a sleight of hand by implying but not stating that the ink drawing (which had only recently been sold as a van Dyck) was by Rubens. The truth is this ink drawing-from-nowhere and without-history had needed to exist if the Berlin Honthorst were to be presented remotely credibly as a Rubens. Had Burchard sincerely believed that the cropped-foot drawing was Rubens’ original ink sketch, he would have felt himself the agent of a remarkable double art historical coup: first, for having identified a famous masterpiece that had been lost for 289 years; second, for having further established that both of the contemporary copies of that original Rubens’ painting (through which it had been known for centuries), had been compositionally misleading in identical manners.

Conspicuously, Burchard trumpeted neither of these “discoveries” [6]. His diffidence contrasts markedly with the reaction of the day’s leading Vermeer scholar, Dr. Abraham Bredius, who believed in 1937 that he had found an unknown Vermeer (in what was the first of a stream of Han van Meegeren fakes). Firstly, Bredius’ certificate of authenticity was ecstatically and unreservedly fulsome: “…I found it hard to contain my emotions when this masterpiece was first shown to me and many will feel the same who have the privilege of beholding it. Composition, expression, colour – all combine to an unity of the highest art, the highest beauty”. Secondly, he rushed news of his discovery onto the scholarly record via the Burlington Magazine (“A New Vermeer”, November 1937).

If Bredius betrayed credulousness as an eighty-two year old scholar, what of Burchard’s manoeuvres as a forty-four year old at the peak of his powers? It can only be said that suspicions are in order. When, shortly after the First World War, the great German scholar, Wilhelm von Bode, was reproached for having certificated an implausible Petrus Christus, he replied, “You don’t understand the intricacies of the German language. After a brief description of the subject I say ‘I have never seen a Petrus Christus like this!'” (- “The Partnership”, Colin Simpson, 1987, p. 240). One must suspect that Burchard’s twinned and circular Rubens attributions were made sotto voce out of fear that his “attributional” heist might be exposed by anyone with an alert eye who appreciated that it is surprisingly common for later copies of original works to be cruder compositionally cut-down and abridged versions – and who would, therefore, recognise the “Honthorst” as a prime member of that type.

We have found that not only are such insensitively truncated pictures frequently encountered (in Rubens twice-over with the Samson and Delilah and the Ontario Massacre, and in artists like Leonardo, Raphael, Caravaggio and Annibale Carracci – see opposite) but, also, that with a little effort they can in almost every instance be shown to post-date the superior models and prototypes from which they derive. As shown opposite, in copyists’ hands, no part of an original composition can be considered sacrosanct. As well as toes, dogs’ noses and cupids’ wings, even portions of dead infants have been cropped to fit pre-existing images to new supports and formats. Mistaking a copy for an absent original is one thing. Disregarding clear and contrary historical evidence, as Burchard would seem to have done, is another altogether. Knowingly elevating adulterated versions to a master’s oeuvre pollutes the well of scholarship and ultimately threatens the credibility of the field.

Such lapses of critical judgement are as common in appraisals of restorations as they are in the making of attributions. How much or little of an original surface has survived the vicissitudes of time and “conservators” attentions might seem a lesser matter but it is not. Professional art critical failures to spot the tell-tale differences between autograph and studio works are the twins of failures to recognise restoration-induced injuries. The differences of states within individual works can be as pronounced as the differences between autograph and studio works (see Figs. 28a, 28b, 29 and 30). Failures of judgement in both areas are frequently found in even the most high-ranking individual scholars.

Making two Caravaggios in one decade

Within little more than a decade the late Sir Denis Mahon upgraded two pictures to autograph Caravaggio status. This might seem unremarkable given that Mahon was a prolific finder/maker of old masters. What is remarkable is that he did so with two versions (of more than a dozen) of the same painting – Caravaggio’s The Taking of Christ. This Caravaggio survives in two formats, one being a truncated version of the other. Mahon managed to endorse one version of each type, doing so in the wake of two “investigative” restorations in which each team claimed revealed authenticity on the basis of its own “discoveries”. (Mahon had serious form in the double attributions stakes – we discuss opposite a painting of Annibale Carracci where he authenticated one version and later suavely switched to another, less abridged, picture. See Figs. 25-30.)

During the first restoration in 1993 in Dublin, a long-attributed Honthorst copy was found to have been made largely without revisions and it was declared the original autograph Caravaggio by Mahon precisely by virtue of its revisions-light painterly fluency. This version was of the truncated type. In Rome in 2004 Mahon conferred autograph Caravaggio status on a work from Florence (where acquired from the Sannini family) that was found to have been made with many and major revisions taken to be “serious afterthoughts as was Caravaggio’s wont”. This version was composed in the larger format and Mahon reportedly said he had “no doubt that this was now the original work”. Dublin was not best pleased and Mahon promptly rowed his position back and claimed that both versions were now original but that one was rather more so than the other. (See “New twist in the tale of two Caravaggios”, Daily Telegraph, 17 February 2004; “A dangerous business”, Michael Daley, letter, Daily Telegraph, 19 February 2004; and, “The real Caravaggio is . . . both of them” Daily Telegraph, 20 February 2004.)

Like the two R.W.P. de Vries of Amsterdam drawings, the two “autograph” Mahon Caravaggios have enjoyed unequal fortunes. In 1993 the (revisions-light) Dublin Caravaggio was loaned to the National Gallery in London and then, permanently, to the National Gallery in Dublin. The later 2004 Florence/Rome Caravaggio with numerous major revisions and other “cast iron” technical proofs enjoyed no institutional protection, being still in private hands. Its cause seems to have fallen into abeyance following legal disputes over ownership. In 2005 the initial 1993 “discovery” of the now institutionally protected Dublin Caravaggio (Mahon enjoyed a long-standing relationship with the National Gallery in London, as a trustee and as a generous benefactor-in-waiting) became the subject of an illuminating, if somewhat parti pris book, “The Lost Painting”, by Jonathan Harr.

In an epilogue, Harr has described a falling-out over the ownership of the Florence/Rome version. Technical examinations of the painting were ordered by court prosecutors without the knowledge of the owners. They were carried out by Maurizio Seracini, a leading private technical diagnostician who has examined something like half of Caravaggio’s output. The pigment Naples Yellow, which contains the metal antinomy, was found. Because that pigment is presently said not to have been used on paintings before 1630 (or “from around 1620”, according to Wikipedia), and therefore twenty years after Caravaggio’s death in 1610, Seracini held the painting inauthentic. Harr accepts the force of this technical testimony and, concluding that Mahon had demonstrably blundered in his support for the Rome/Florence painting, imagines that that old scholar’s long-time adversary, Roberto Longhi, might now be enjoying “a mirthless laugh” over Mahon’s discomfiture. The conclusion was hasty and perhaps too trusting of technical testimony.

It is certainly the case that the presence of a modern, manufactured pigment within the fabric of a supposedly old painting can safely be considered fatal to an attribution. However, Naples Yellow is not a product of a known and precisely dated modern manufacture – such as Prussian Blue of 1704 – it is ancient and greatly pre-dates Christ. Harr acknowledges that the pigment is found on a painting of 1615 by Orazio Gentileschi – just five years after Caravaggio’s death. Harr further reports that traces of this pigment had been found on another Caravaggio, his Martydom of St Ursula, which is owned by Banca Intesta in the Palazzo Zevallos, Naples. He reports a suggestion that the offending material might have come from an 18th century restoration that had subsequently been removed. Such hypothetical exculpation would only be necessary if claims that Naples Yellow could not have been used by anyone before 1630 were Gospel and if the painting’s attribution was insecure. Neither is the case. The Martyrdom is one of Caravaggio’s most reliably and completely documented works so there can be no question about its authenticity. Further, it was almost certainly his last work. It was recorded as still being wet in May 1610. If this painting contains antimony, and unless evidence exists to support the former existence of a now entirely disappeared 18th century restoration, we should accept that this material has now been found in two Caravaggio paintings and adjust the technical literature chronologies accordingly.

In this episode, we see that negative hard “scientific evidence” can be discounted on the basis of assumptions, hunches, and suspicions. We also see that the claimed chronologies of materials within the literature of technical analysis are moveable and, only ever, provisional feasts. (For such chronologies to be considered reliable it would be necessary for every painting in the world to be analysed at the same time by the most advanced technologies – and even then, subsequent technical advances would require further examinations: it is common for old formerly “advanced” tests to be re-run in conservation departments when new and improved apparatus become available.) We have asked Seracini, in the light of Harr’s comments, if “it is still the case that the presence of antimony is considered an absolute technical disqualification in paintings made before 1630?” Meanwhile, Jacques Franck, the Consulting Expert to The Armand Hammer Center for Leonardo Studies at The University of California, Los Angeles, advises that:

“The best scientific bibliographic reference concerning the history and chemistry of pigments over here is: J. Petit, J. Roire, H. Valot, “Des liants et des couleurs pour servir aux artistes peintres et aux restaurateurs”, EREC éditeur, Puteaux, 1995. Regarding Naples yellow, it says: ‘(Lead antimonate yellow) was rediscovered in Europe at the end of the Middle-Ages and was later mentioned in a document dating from 1540, “Pirotechnia”. The oldest recipes, written in 1556-1559, were supplied by Cipriano Piccolpaso…who was a painter of ceramics”

Although those recipes were indeed written primarily in connection with ceramics, given that they existed before Caravaggio’s birth (1571) it should never have been insisted that knowledge of them could not have been obtained by contemporary painters. As it happens, a study on Lorenzo Lotto’s pigments was made in connection with the exhibition “Lorenzo Lotto” (Venezia, 1480 – Loreto, 1556-57) at the Scuderie del Quirinale in Rome in spring 2011. On that occasion, more than fifty Lotto paintings spanning from 1505 to around 1556 were studied using non-invasive techniques by Maria Letizia Amadori, Pietro Baraldi, Sara Barcelli and Gianluca Poldi. The authors’ report (pages 2 and 19):

“About yellows, he uses both lead-tin and lead-antimony (Naples yellow) pigments, the latter found by XRF, in works starting from 1530 to the last years: it can be related to the ‘zalolin da vasarj’ cited by Lotto in 1541 in his account book (Libro di spese diverse)”, and, “As XRF analyses show, in some works, starting from 1530 to the last years of the century, also lead-antimony (Naples yellow) pigments, can be found, together with the previous yellow or almost alone: they can be related to the “zalolin da vasarj” cited by Lotto in 1541 in his account book (Libro di spese diverse).”

Thus, the presence of antimony would seem not to have given grounds for dismissing the Florence/Rome version of the Taking in the courts. Perhaps we can see that it might have been more to the point for the courts to require the production of the best possible photographs of as many of the versions as possible to permit visual comparisons of the two rival versions. There are many indications of the limitations of modern conservation practices to be had in Harr’s fascinating account. On page 169 he describes an encounter between the Dublin National Gallery of Art’s two picture restorers, Andrew O’Connor and Sergio Benedetti (who had re-attributed the Hontorst Taking to Caravaggio, and who had experienced “a fleeting moment of doubt” about his attribution while cutting ever larger ‘windows’ through the painting’s varnish):

“One day, about three weeks after the painting’s arrival, O’Connor and Benedetti crossed paths in the studio. Benedetti was staring at the painting. He stood with his arms crossed, his eyes narrowed in concentration, his mouth compressed into a frown. ‘Look at the arm of Judas’, Benedetti said to O’Connor. ‘What do you think?’ O’Connor studied the painting. ‘What are you getting at?’ he asked. ‘It seems too short, doesn’t it?’ said Benedetti. It did…O’Connor realised that Benedetti was wrestling with his doubts. ‘Well’, said Benedetti finally, ‘he wasn’t a perfect anatomist. He made other errors like this. In the Supper at Emmaus, the apostle’s hand is too large.’”

In this recollection we might be witness to a double failure of art critical methodology. Given his doubts, Benedetti might have assembled all available photographs of the many versions of this painting to determine whether or not the short-coming that concerned him was unique or common to (some or all) other versions. A greater lapse may be evident in the fact that while Benedetti expressed anxiety over the arm of Judas, he seems not to have done so over the compositionally and emotionally more important advancing left arm of the fleeing St John who is seen behind Christ and Judas. In the Dublin version, the arm of St John is cropped above the elbow and not above the wrist as it is in the Florence/Rome version. (On the compositional function of the arm in the Florence/Rome version, see comments at Figs. 21 and 22.)

To repeat what should be self-evident: pictures are made to be looked at. When, as with this Caravaggio, multiple versions exist we should make hard detailed visual comparisons of each against the others, if necessary (and it could hardly be otherwise when so many versions exist) by photographic means. When later copies or engravings exist we should make careful comparative estimations of their relationships to the various contenders. Whenever there are cut-down versions of more expansive compositions, we should always consider which state is likelier to have been the primary and which the secondary one. Visual comparisons in attributions, as in restorations, are of the essence. They should never be neglected, let alone discounted, on the authority of some technical evidence that may or may not be soundly framed; that may or may not be selective or loaded in its presentation; and, that will, in any event, soon be rendered obsolete by more up-to-date equipment. The informed human eye is our best “diagnostic tool” in the study of art and will remain so no matter how much money and resources might be thrown into technical studies. It remains the greatest tragedy that Bernard Berenson so badly debased his own critical currency with his shady Duveen dealings. On the primacy of the visual in visual art forms he was peerless:

“I am here concerned with names in painting. When I pronounce the words Giotto, Michelangelo, Leonardo, Giorgione, Durer, Velazquez, Vermeer, Ingres, Manet, Degas and hundreds of others, each stands for certain qualities which I expect to find in a painting ascribed to them. If the expectation fails, then no argument, no documentary evidence, be it biographical, historical, psycho-analytical, or radiological and chemical will persuade me.”

That was and is how it should be.

1 The Times, letter, 13 August 2014:

“Sir, Gerald Fitzgerald (letter, Aug 12), misses an important point when calling for a tiny levy on art sales to fund an independent centre for provenance research. Although such a levy might cost only .05 per cent of annual art sales, currently standing at some $60 billion, if effective, such a centre would reduce the supply of works on the market by something like 40 per cent – at least in the view of the late Thomas Hoving, a former director of the Metropolitan Museum of Art, New York. The art world is very quick on its feet: when calls were made in the 1930s for an independent centre of art restoration research, then director of the National Gallery in London, Kenneth Clark, promptly established a department of conservation science in order, as he later confessed, to ‘have in the background what purported to be scientific evidence to “prove” that every precaution had been taken’. Although self-policing may be an unrealistic ambition, governments could help considerably and at little cost by making it a statutory requirement that vendors should disclose all that is known and recorded about the provenance and the restoration treatments of works of art. As things stand, it can be safer to buy a second-hand car than an old master painting.”

2 The Massacre of the Innocents which came up at Sotheby’s on 10 July 2002 as a very recent Rubens upgrade is a case in point of misleading assurances and over-ridden technical evidence. In a long sale catalogue entry it was said that technical analyses and condition reports had been commissioned and that these were available on request. The implication was clear: we have exercised all possible due diligence and this painting has emerged with flying colours. That implicit reassurance evaporated on a close reading of the material – as we reported in the October 2002 Jackdaw (“Is this £49.5 million painting by Rubens?”). The reports were, by their nature dense and couched in technical language. Nonetheless they clearly contained information that was highly injurious to the attribution and to the picture’s claimed early dating of c. 1609-11. One technical fact alone should have sunk the attribution. It was found in the last paragraph of the last report. As we put it: “The author of a report on the tree-ring dating…concludes that a date of execution for the picture only becomes ‘plausible from 1615 upwards’.” In other words, the panel on which this picture was painted could not have been manufactured at the time the picture is said to have been painted – and this dating could not be amended because, like the Samson and Delilah, the picture was only remotely credible on stylistic grounds if seen as the product of a (fancifully claimed) brief stylistic abberation in Rubens’ oeuvre said to have occurred on his immediate return from Italy in 1608. As well as being on wood that was too recent, the picture contained the wrong materials: “A pigment, orpiment, that is found in no Rubens is present here. A second pigment, smalt, said to have been in use ‘mainly in the mid-seventeenth century’ and which seems only to be found in Rubens’ later works is also present. The orpiment yellow is anomalous not only in its presence but in its manner of application – it is mixed with lead-tin yellow. Such a combination is said to be ‘unusual since it was considered unstable’ and, even, to be a practice ‘not encountered in 17th century works’”. This was not just a twice-over dead attribution: “Speaking of Rubens’ debt to classical sources, the anonymous author of the catalogue entry correctly concedes, ‘one of the background figures appears to derive from the Borghese Gladiator’. There follows immediate self-disavowal: ‘it cannot’ so derive, he/she contends, because ‘though famous in subsequent centuries, the Borghese Gladiator was not excavated until late in 1611”. This painting on the wrong (too recent) wood, with what would normally be considered disqualifying (out of period)materials, and which contained a miraculous allusion to a future event, was presented to the world as a major art historical discovery. That “discovery” had taken place very shortly before the sale. The upgrading of this centuries old studio work had been made by just five experts only three of whom were identified. We put the question: “Can it be right that we are all being asked to share this leap of faith when the experts, displaying a seeming ignorance of – or disregard for – so much germane material evidence, have yet to declare their hands or publish accounts of their vital endorsements?”

3 Jonathan Harr reports in his 2005 account of the upgrading of a Honthorst to Caravaggio (“The Lost Painting” p. 222) that when the picture, The Taking of Christ, was examined at the National Gallery in London it was found that its ground (priming layer) was anomalous: Ashok Roy, the head of science, observed, as Harr reports, that “the composition of this particular ground was strange – ‘bizarre’ was the word used. It contained reds and yellows and large grains of green earth, a pigment composed of iron and magnesium. Grounds usually contained lead-based pigments and calcium, which dry quickly. Green earth dries slowly. This primer looked to Roy like a ‘palette-scraping’ ground – the painter had simply recycled leftover paints from his palette board to make the priming layer.” Well, yes, someone evidently had – but what in Roy’s detailed technical analysis of the ground might have suggested that on this occasion Caravaggio had departed from his own habits in order to do so? When the painting was exhibited in a special exhibition (“Caravaggio ~ The Master Revealed”) at the National Gallery of Ireland in 1993, the catalogue gave a different spin to Roy’s research: “Analyses have shown that the ground is composed of a brown pigment, heterogeneous and unevenly applied. Several pigments were mixed with it: lead white, red and yellow ochre, umber and large granuli of green earth.” On a casual reading: impressive and reassuring technical detail and expertise. No mention of bizarreness. No acknowledgement of what was for Dr. Roy, a perplexing departure from Caravaggio’s known practices. On page 160 Harr reports that Sergio Benedetti (the Dublin National Gallery of Art restorer who first made the attribution)“saw immediately that the painting had been relined at least once before” and judged the present lining canvas to be at least a hundred years old. In the National Gallery catalogue Benedetti reported that “the picture has undergone at least three interventions, probably accompanied each time by a relining of the canvas. One of these linings caused a shrinking of the surface in some limited areas.” What is not said is that Benedetti two of the three-plus hypothecated linings had been made by Benedetti himself the first having caused cracking. Harr reports that after the first lining “There is much dispute about what happened next. For Benedetti, restoring the Taking of Christ was the greatest moment in his professional career, and to this day he adamantly denies that he had any problem relining the painting. O’Connor and others at the gallery, however, tell a very different story. According to them, he came close to ruining the painting.” Andrew O’Connor, the Gallery’s chief restorer, said that Benedetti had elected to use a densely-woven Irish canvas rather than wait for an appropriately matching loose-weave canvas to arrive from Italy. When Michael O’Olohan, the gallery’s photographer, who had made detailed photographic records of every inch of the picture’s surface, saw the painting immediately after its first relining, he could not believe his eyes and recalled “There were areas that had hairline cracks, like a sheet of ice that has started to melt, a flash of cracks all over it. I was shocked. I couldn’t believe it.” O’Connor explained that because the Irish canvas was densely woven, “it did not absorb the [water-based] glue at the same rate as the old Italian canvas. It had not dried properly and had contracted, pulling with it the Italian canvas and raising ridges, small corrugations, in the paint surface. Along these corrugations, the paint layer had cracked and lifted.”

4 In the ArtWatch UK Journal No. 21, (“The ‘Samson and Delilah’ ~ a question of attribution”), Kasia Pisarek wrote: “Dr. Ludwig Burchard was an active Rubens attributionist in Berlin before the Second World War and in London afterwards. Several paintings formerly attributed to Rubens’s school or studio or even to another artist (such as Sampson and Delilah), were reinstated by Burchard as by the master. I traced many of his attributions – he was not infallible in his judgement and changed his mind. Surprisingly, over 60 pictures attributed by Burchard to Rubens were later down-graded (in Corpus Rubenianum) to studio works, copies or imitations.”

5 The principal challenges to the attribution came from two artist/scholars, Euphrosyne Doxiadis, author of the award-winning 1995 book “The Mysterious Fayum Portraits: Faces from Ancient Egypt”, and Kasia Pisarek whose 2009 doctorate dissertation was entitled “Rubens and Connoisseurship ~ On the problems of attribution and rediscovery in the British and American collections (late XIX – XX c.)”. In 1986 Euphrosyne Doxiadis began researching the painting’s credentials with fellow art students Steven Harvey and Siân Hopkinson. Their findings were compiled in a report submitted to the National Gallery in 1992 and which is now held in the painting’s dossiers. (It is also available online at this site: Their challenges to the attribution were covered in reports in the Times (“Artists raise fresh doubts on gallery’s Rubens masterpiece”, 22 September 1996, and “Expert denounces National Gallery’s Rubens”, 25 November 1996), and in The Independent on Sunday (“Tell-tale sign that £40m Rubens could be a copy”, 21 May 2000). Researches begun in 1990 by Kasia Pisarek prompted two articles on 5 October 1997 by the Sunday Times’ art critic, Waldemar Januszczak (“A Rubens or a costly copy?” and “National’s £40m Rubens could be fake”). In the latter article, the then director of the National Gallery, Neil MacGregor, conceded that “the scholar raises some serious questions that I cannot easily answer”.

6 As Dr. Pisarek put it in the ArtWatch UK Journal 21 (“The ‘Samson and Delilah’ ~ a question of attribution”): “Both the rediscovery and the sale of this early Rubens masterpiece should have been well publicised in the press, yet there are no records of it in any art magazine (I checked most art journals published in 1929-30). However, other, even minor, Rubens discoveries could easily be traced (‘Forgotten Rubens found in Austria’ – Art News, 1930; ‘Van Diemen sells notable Rubens’ – Art News, 1931 etc.) Strangely, the Samson and Delilah was not even included in Valentiner’s ‘Unknown Masterpieces’, co-edited with Burchard, and published in 1930, which presented important little-known and rediscovered paintings. Dr. Burchard only wrote about it briefly in 1933, and only in a short note.”

Comparison of the two works shows in the former, the exceptional grace, composure of design and warmth of colouring for which the artist is revered, while the latter asserts an uncharacteristic stridency that required the National Gallery to posit a “special-but-brief” stylistic Rubens interlude.

Just as the National Gallery’s The Virgin of the Rocks (below) is a cut-down replica version of the Louvre’s Leonardo original, so the Ontario Massacre of the Innocents is a cut-down version of the larger canvas at the Musée des Beaux-arts in Brussels. Although now said to be a “studio replica” the latter was judged original by such eminent Rubens authorities, as Gluck, Held, Van Puyvelde and Michael Jaffé.
The cropping of motifs in the Ontario version seems particularly insensitive as it includes the two murdered infants who, in the Brussels version, were depicted whole and set (like Samson’s original toes) comfortably inside the edge of the painting. How likely is it that Rubens would have cropped his figures in this manner or, if by chance he had, that a copyist would presume to extend and make whole his composition ?
Above, Figs. 14a and 14b. The regretably unequal photographic quality of this comparison does not mitigate the disturbing cropping of the infants in the Ontario version (left) which, like the National Gallery Samson and Delilah, spent many years as studio copy in the Liechtenstein Collection.

In the latter we encounter an uncharacteristic indifference to design, sloppiness of treatment and iconographic brutality in the depiction of an infant saint. While the securely autograph Louvre painting has never been in question, considerable argument has arisen over the extent to which Leonardo’s hand is present in the National Gallery version.
In the catalogue to the National Gallery’s 2011-12 exhibition “Leonardo da Vinci ~ Painter to the Court of Milan”, the gallery’s head of restoration, Larry Keith, (who had restored the Virgin of the Rocks prior to the exhibition), was in no doubt that the London version was entirely autograph. He wrote of “discoveries” made in the course of restoration:
“…What we discover is a painter firmly grounded in traditional practice who was able to stretch his methods and materials to express unprecedented intellectual and artistic concerns. However, these painterly interests were only a part of a larger pursuit; he believed that careful observation of all manner of natural phenomena was essential for both new knowledge and a deeper understanding….The National Gallery Virgin of the Rocks is a painting that is at once unique and highly representative of how Leonardo worked. Produced in fits and starts over the last 15 or so years of a commission that took 25 years to complete, it is a composition of the most artful complexity and an image where local colour was sublimated to the newer demands of tonal unity…The National Gallery Virgin of the Rocks…is manifestly uneven in finish and execution but, perhaps, paradoxically, this quality allows us to explore key issues in his painterly practice – methods, materials, collaboration, delegation and finish – and thereby understand better the larger question of the relationship between his painting techniques and his artistic intent…”
Needless to say, this conviction that the picture is an entirely autograph, unique-but-representative Leonardo is not universally accepted. Even at the National Gallery, Leonardo’s authorship has not always been accepted. In 1947 the curator Martin Davies took issue with the picture’s very many doubters (who included the recently former director of the gallery, Kenneth Clark):
“It has to be admitted at the outset that the identification of Leonardo da Vinci’s pictures is by no means the sure and simple thing one might think. It is a fact that there exists no picture of his Milanese period that has not at one time been rejected by famous critics; except for the Cenacolo, which is ruined, and hardly suitable for stylistic criticism at all! The whole subject of Leonardo’s style is therefore somewhat doubtful; but in the particular case of the Virgin of the Rocks in the National Gallery, there has been a good deal of agreement that Leonardo himself painted little or none of it…”
Davies believed the critics to be wrong, but in making his case he conceded many things germane to our concerns here. He acknowledged that this painting was a replica and that it was “quite likely under these circumstance that he [Leonardo] had no great interest in the work”. Although a replica in the sense that Leonardo had been obliged to paint a second version of a commission, Davies draws an ingenious distinction: “the picture is not simply a replica” because so much time had passed that Leonardo had left one artistic era and entered another, making “the picture […] the replica of a work in an older and different style”. Leonardo’s new style “was perhaps expressed rather imperfectly, because the picture is a replica.”
The National Gallery’s suggestion that its “Rubens” Samson and Delilah does not look like any of its twenty-odd secure Rubens’s because he had worked for a brief period in a style like none of his others was a desperate denial of the fact that its “out-of-style” traits stem from its true status as a replica. A more frank acceptance of the Virgin of the Rocks’ acknowledged replica status might might have spared decades of convoluted apologias. Where Larry Keith sees in the Virgin of the Rocks material evidence throughout that “careful observation of all manner of natural phenomena was essential for both new knowledge and a deeper understanding”, another student of Leonardo and Nature, Ann Pizzorusso (who trained as a geologist before becoming an art historian) took an entirely contrary view. For Pizzorusso, the gallery’s claims of some radical shift of style as a means of accounting for the London picture’s problems were entirely and demonstrably without foundation. She was clear on this site that no shift of style could account the picture’s problems because none had occurred:
“Using a date of 1510 for the Virgin and St. Anne and a date of 1483-86 for the Virgin of the Rocks, both in the Louvre, we have proof that Leonardo did not change his style, and that, if anything, he became more fanatical in his quest for geologic accuracy, developing new paints and techniques for natural depiction and driving his students to deliver the most accurate depiction of nature in their own works. So we must ask the question ‘How and why could Leonardo have changed his style to produce a work so lacking in geological and botanical accuracy as the Virgin of the Rocks in the National Gallery in London?’ There is no evidence Leonardo changed his style and now, with the recently cleaned Virgin and St. Anne, we have that proof. We also know that his students were inculcated with his passion for accurate depiction of natural objects so we must also exclude his students as authors of the National Gallery work.”
Writing nearly a decade earlier than Davies, Kenneth Clark, discussed the head of the angel in the London Virgin of the Rocks in his 1938 book of (marvellous black and white comparative photographs) “One Hundred Details from Pictures in the National Gallery”. Of the angel’s head, he wrote “This is the one part of our Virgin of the Rocks where the evidence of Leonardo’s hand seems undeniable…” For Clark, changes in Leonardo’s work over the years were evident, but unlike Davies later and Keith much later, he seems not to have seen evidence of the Later Leonardo equally and everywhere across the painting. For Clark, this curate’s egg of a picture was, in only select parts, very, very good indeed. Of the angel’s head:
“Beautiful as it is, this angel lacks the enchantment of the lighter more Gothic angel in the Paris version. It embodies the result of Leonardo’s later researches in which ideal beauty and and classic regularity of chiarascuro were combined, with a certain loss in freshness, but with an expressive power which almost hypnotized his contemporaries.”
Clark was onto something interesting when speaking of Leonardo’s “hand” – the characteristic touch and surface of his paintwork. It so happens that there was a tool to hand that could have been the greatest boon to those charged with making attributions: high quality micro-photography. Clark, as his own two books of National Gallery details show, was certainly alert to the potency of high quality photographs but he used his comparisons of details to flag up differences between artists in their treatments of similar subjects. That was a perfectly interesting and instructive application. He overlooked, however, the possibility (and the great profitability) of taking, assembling and collating many thousands of details from the most secure, “Gold Standard” paintings, so as to create visual benchmark indicators of artists’ distinctive methods. (Just imagine Morelli and His Ears in an era of digital photography and computers.) If the failure to pursue such programmes in the immediate impoverished years after the Second World War might be excusable, what excuse exists in today’s digital era? The pioneering photographs (shown here at Figs. 18 and 19) by Professor A. P. Laurie in his 1949 book “The Technique of the Great Painters” constituted a perfect template for a means of more accurate visual appraisals – we surely have fewer excuses today than any generation in history for stumbling as if half-blind through the minefield of attribution?
Below, Fig. 17: Martin Davies’ 1947 large format essay on the gallery’s Virgin of the Rocks carried 16 highly informative plates (including this one below of the infant St. John which appears to suggest multiple but vain attempts to keep the toes within the picture?

Above, Fig. 18: Professor A. P. Laurie explained the significance of this pair of spliced photographs in his 1949 book “The Technique of the Great Painters”:
“This illustration is a photomicrograph of the highlight on the shoulder of [Rembrandt’s] Woman Bathing, National Gallery, No.54. The patch pasted on is from a photomicrograph of a picture whose attribution had to be tested. It will be seen that the brushwork is identical in both cases. It is possible for a skilled forger to imitate a signature, but it is quite impossible to combine the quality of the paint, the nature of the brush, and the handling of the painter, so as to reproduce this complete identity.”
Below, Fig. 19: Prof. Laurie explained the significance of the brushwork below in these terms:
“There is a very interesting portrait of Verdonck [in the National Gallery of Scotland] holding in his hand the jawbone of an ass. It was known from an engraving that such a picture must have existed, but it had apparently disappeared. The Edinburgh gallery possessed a picture by Frans Hals of a man holding a wine glass in his hand. An X-ray revealed that underneath the the wine glass was a painting of the jawbone of an ass which had been painted out by some restorer and replaced by the wine glass. On careful cleaning, the restorer’s work was removed…[this photomicrograph reveals] the rapidity with which Frans Hals laid in stroke after stroke with absolute certainty. In fact the painting seems to be alive, and one can almost see the brush moving over the surface. it would be impossible to mistake this work for the brushwork of Rembrandt…”

In this his last book, the late Professor James Beck of Columbia University, and the founder of ArtWatch International in 1992, wrote:
“Two paintings, a mini aspiring Raphael da Urbino Madonna and an equally tiny aspiring Duccio di Buoninsegna Madonna were sold for record prices in 2004. The first was bought by London’s National Gallery and the second by New York’s Metropolitan Museum of Art. These objects and the mode in which their attributions to their famous presumed authors were achieved document a breakdown in modern connoisseurship. The two objects represent a total expenditure of public money exceeding 100 million dollars for pictures the size of a sheet of paper. These remarkable sales could not have transpired without the participation of art experts whose role was indispensable in offering authentifications of the pictures. This book will seek to define the system of attributing works of art, examine the methodology, treat in depth case studies of recent connoisseurship including the two pictures just mentioned. In addition to what is regarded as a monumental failure on the part of the experts, the use and misuse of public funds is an issue that lies just beneath the surface.”

This small pair of photographs from 1967 is sufficient to show the profound compositional consequences of an extension of one work or a truncation of another. Regardless of the photographs’ poor quality and regardless of the paintings’ relative merits, (both of these, incidentally, have been supported as autograph), the question can be posed in the abstract: Which of the two compositional formats is likelier to be the prime version? Further, if Caravaggio had painted in the truncated format, would he or a copyist then likely have added an extension to the arm of the fleeing disciple in another version? Our feeling is that the Florence format has to be considered to be superior compositionally; more dynamic dramatically; less like a stiff and claustrophobic tableau; and, altogether more expressive of the magnitude of the pandemonium and horror that attended Judas’ fateful act. Whether the Florence picture is the original autograph version has to be established but reports of its pronounced revisions weigh in its favour. Desperately needed is a collation of high quality photographs of all the versions of the paintings, along with detailed photographs of the same, or greater, quality of those published by Prof. Laurie.
Above, Figs. 23 and 24: The Dublin and Rome/Florence versions of Caravaggio’s The Taking of Christ, as reproduced in the Daily Telegraph. Sir Denis Mahon deemed both of these works – at the same time – to be the Caravaggio original.

Of the two versions (see a detail of the rival Vienna picture below at Fig. 28b) Mahon has supported both as the authentic original work – but this time did so consecutively, not simultaneously, as with the Caravaggio Taking. He championed the Vienna picture until the Prado one emerged. Unabashed, he saw merit in his own mistake, saying (in the 2005 exhibition catalogue) of his critical re-positioning :
“When I first wrote about this composition, some fifty years ago, my observations on style and chronology were based not on the Prado painting, since this was as yet unknown, but on the excellent early copy in the Kunsthistorisches Museum in Vienna and on the preparatory drawings for the figure of Adonis in the Uffizi. When the Prado painting was first published in 1965, by Pérez Sánchez, it was gratifying to realize that, although all those of us who concerned ourselves with Emilian painting had mistakenly assumed that the Vienna picture was Annibale’s original, one’s intutitions about the importance of the work and where it fitted in the artist’s evolution were confirmed.”
This was dissimulation: had Mahon been alert to what might be called The Problem of Arbitrary and (otherwise) Bizarre or Inexplicable Croppings, he would have spotted the tell-tale warning in the cropped nose of the hound on the right of the Vienna version. This would have been the more likely had he consulted, as well as figure studies in the Uffizi, the etched copy of the original made in of 1655 by Luigi Scaramuccia (see Fig. 27, below). This delightful record shows not only that the hound’s head (like Samson’s toes elsewhere) had been set comfortably inside the picture, but, also, that the landscape at the top right was more extensive and contained an architectural feature (doubtless of some iconographic significance). Curators and restorers too often disregard the testimony of graphic artists, when, within their limits and styles, they are essentially respectful of the works they were paid to copy. (A copyist inclined to go his own way would likely get less not more employment.)
Below, Fig. 27: Luigi Scaramuccia, Venus, Adonis and Cupid, 1655, second state, The British Museum (here mirrored).
Above, Figs. 28a and 28b: Details of the Prado’s Carracci Venus, Adonis and Cupid (left), and the Vienna Kunsthistorisches Museum version (right).
If Mahon corrected one error with this painting, he perpetuated others. The catalogue to the exhibition that celebrated the Prado’s restoration, produced the customary self-congratulatory sponsor’s waffle (here The Fundación Reale). Less forgivable was Mahon’s claim that the restoration helped establish the date of the original work. Mahon had been a belligerent champion of National Gallery restorations when at their worst in the post-war years, mocking, in tandem with the gallery’s head of science, the objections of scholars like Sir Ernst Gombrich (who had to wait a third of a century for a full technical vindication of his objections – see How the National Gallery belatedly vindicated the restoration criticisms of Sir Ernst Gombrich and 24 November 2011)
What is unsaid in the hype of big business-sponsored restorations, is that a restorer can never recover what has been lost and that by cosmetically dressing up degraded works, imparts a spurious simulation of health and historical veracity. No restoration exhibition should ever take place without the inclusion of all extant visual records of the work(s) in question. If we disregard the testimony that exists in this area, we enter a world of “art conservation” make-believe. In doing so, we leave ourselves ill-quipped to address the most urgent questions of attribution and condition. Sadly, with this Carracci painting, the two versions have experienced what restorers euphemistically call “different conservation histories”. Which means is that they have suffered to varying and unequal degees, physical assaults on their fabrics and their pictorial skins. We are all obliged to acknowledge and address these terrible truths. Not least because all the inherent difficulties of making attributions are exacerbated by these various histories of “treatments”. On the testimony of the etching, it would seem that the Vienna hound lost considerable shading to the side of his head, while his elaborately jewelled collar survived much better than that seen in the Prado version. This tells us that neither work remains a true witness to its own original self and that, therefore, theories and judgements made on the basis of the pictures’ present selves should come with careful qualifications and health warnings, and not with some facile celebration of glorious recoveries.
The differences that restorations make to individual pictures can be as great or greater than the differences that might originally have existed between an authentic original work and an extremely high quality copy of it. It should be accepted that one of the consequences of past restorations is that making sound appraisals of the merits of once closely related versions of paintings is made the more difficult. Some indication of how dramatically transforming restoration treatments can be can be might be gauged by the pair of details below (Figs. 29 and 30) from the Prado’s records of the same painting. Properly read, their inclusion, and that of the two states of the Scaramuccia etching in the Prado exhibition catalogue might constitute a most useful contribution to knowledge and understanding in this arena.

Black is a Colour

23 March 2012

We reported in an early Journal that Anna Somers Cocks, when editor of The Art Newspaper, had observed that Frans Hals employed as many as six tones of black and that these were “too often deadened by bad cleaning”. This prompted a response from a painter colleague.

Iain Walker wrote:

Anna Somers Cocks’ observation that Frans Hals painted with up to six tones of black reminded me of another appraisal made some years ago when Hals was being shown at the Royal Academy. An eminent art critic noted in his review of the exhibition that Vincent van Gogh had claimed to have counted no fewer than 28 different blacks in a Hals painting. The observation, the critic accepted, may have indicated Vincent’s preoccupation with the picture but it could not have been so because research had revealed that at that date there were only six blacks in production. Many readers may have concluded that poor Vincent had got it wrong again, and that this was a critic who did his homework.

At the time of this review, a project exploring the nature of black and the assumptions we have of it, was being conducted with the first year students at the City and Guilds of London Art School in Kennington. To this end, one side of the studio had been painted black throughout and filled with black objects and materials: black cottons, velvets and silks, as well as a numerous household objects that were painted or sprayed with matt or gloss paint. Coal and soot were also used.

The task given to the students was to make a perceptually accurate painting of a section of the studio without using any black paints. They met this requirement by mixing their own blacks from the colours contained in their paint kits. It was pointed out that Francis Bacon often produced a black by mixing sap green with alizarin crimson. The students also made use of Prussian blue, cobalt, burnt umber, violet etc. Their studies swiftly established that it was entirely possible to make an optically accurate transcription of a black set-up containing many black objects without ever having recourse to any commercially available black paint.

In painting, all colours and tones are relative. Margaret Meade cites the Eskimos as having 17 words for white. When confronting an all black set-up, it soon becomes apparent that there are greenish blacks, reddish blacks, bluish blacks and so forth. Theoretically, there may be a black which absorbs all incident radiation but even a material as black as soot apparently reflects 3% of incident light. Couple this fact with the effect of “simultaneous contrast” and it is hardly surprising that most painters think of black – and white – as colours in their own right and not just as means of creating a tonal range in a painting, as there other ways to do this.

I recall the above as a demonstration of how well-meaning academic research, although possibly correct in one way, can also be misleading and harmful when applied to painterly practice.

“I remember visiting the Delacroix house in Paris, where they have a palette on which he’d mixed a whole row of grey tones, each looking like a pearl, and each mixed from colour, not from black and white. Instead of darkening yellow with black, he darkened yellow with purple.”
From Artists on Art, Martin Gayford, The Daily Telegraph, 13 January 2001.
“I cannot help thinking that something important is being lost and that we ought to refresh our eyes with the more subtle harmonies for which they were designed. The dead of winter is the time to do this. For life has retreated, leaving its many colours half-hidden but perceivable, and the landscape is filled with a subtle counterpoint that could never feature on the telly. The lesson so patiently taught by Corot, Turner and Cézanne – that no natural object is truly monochrome, and that even in the blackest thicket can be discovered all the colours of the palette – is repeated by winter. And that is why there is no better time to visit the country, to walk or ride in the fields and to take the chance of the weather for the sake of the eyes…It is an interesting exercise to stare into a dark, denuded hegerow and count the colours. Soon you will come to see that this unassuming, unclamorous thing could not be transcribed in paint without using the entire pallete: every shade of red and blue, from salmon pink to scarlet, and from deepest indigo to pale forget-me-not, is lurking there, recuperating from the light of summer. And as you watch these hues glimmering like embers you come to understand the myster of colour: how red excludes green and yellow blue; how white is somehow not a colour at all and the metal shades are like glosses in which colours are trapped and made invisible. These strange phenomena are not explained by the physics of light – a fact which Goethe noticed, and which led him to compose his great treatise on colour. They are not facts about things, but about us seeing things. Pondering them we are also pondering the mystery of consciousness. How is it that the world not only is, but is also revealed? Why was it not content just to be?”
