Problems with “La Bella Principessa” – Part II: Authentication Crisis
In Part I we discussed the look of the so-called “La Bella Principessa” drawing and showed that while it bears no comparison with Leonardo’s female portrait type, it sits comfortably among 20th century fakes (see Fig. 1). Here, we consider the singular campaign to have this work accepted as a Leonardo.
“LA BELLA PRINCIPESSA” AND THE (DECOROUS) COMPANY SHE BEST KEEPS

A SINGULAR CAMPAIGN OF ATTRIBUTION
The nine years long campaign to have the drawing “La Bella Principessa” accepted as an autograph Leonardo da Vinci is faltering even before our series of examinations is completed. The leading proponent, Professor Martin Kemp, is said in the May 2016 Art Newspaper (Vincent Noce’s “La Bella Principessa: Still an Enigma”) to have his “reputation on the line” in the wake of our posts and an article “How reliable are today’s attributions in art? The case of ‘La Bella Principessa’ examined”, that was published in the Polish scholarly journal Artibus et Historiae, no. 71, 2015 (“La Bella Principessa – Arguments against the Attribution to Leonardo”) by Dr. Kasia Pisarek, an independent art historian (and ArtWatch member). In delayed response to our January 2014 suggestion that the disputed drawing’s author might have been the painter/restorer Gianinno Marchig (see Art’s Toxic Assets – Part II), Kemp now alleges on his blog that we are making “scurrilous and unsupported” attempts to “divert the argument into claiming that Jeanne Marchig lied profusely”. This is not the first such slur against us from that quarter. When Professor Kemp reviewed the James Beck/Michael Daley book Art Restoration: The Culture, the Business and the Scandal in 1994 he made similarly unfounded charges which we rebutted immediately. In recent years Kemp has cast his denunciations more widely and generally against his fellow scholars. (See below.)
Notwithstanding the “La Bella Principessa” campaigners’ belligerence towards doubters, and Professor Kemp’s own publicly bullish support for the attribution, his position on “La Bella Principessa” is untenable in terms of the work’s artistic properties and its emerging circumstances – as indeed is the methodological model for attributions that he hubristically offers to fellow scholars in connection with the Leonardo upgrades that he supports (see below).
Pace Kemp’s charge of evasion, it would be evasive not to consider Marchig’s role when appraising a drawing reportedly bought by a Panamean, Jersey-based company nine years ago at a requested discount for $19,000 but which now, as a claimed Leonardo, lives in a Swiss vault and is said to be insured for $150 million. We should all consider the circumstances and nature of this particular work and the assiduous, sometimes muscular campaign to upgrade it. The old masters market is fragile. The accelerating expanionism of recent years cannot be sustained. The market cannot afford to take in too many too-hopefully upgraded Leonardos, Michelangelos, Rubens’s, Van Dycks, Caravaggios and so forth. Aside from the resulting adulteration of scholarship, markets, as we all now appreciate, lose confidence and crash when too high a proportion of toxic assets is thought to have been bundled in among the bona fide.
PROMOTING THE DRAWING THAT CAME FROM NOWHERE
What is now presented as Leonardo’s “La Bella Principessa” of c. 1496 was sold anonymously at Christie’s, New York, in 1998 for $22,850 as a work without provenance. Twelve years later, Jeanne Marchig, the widow of the artist/restorer Giannino Marchig who had worked as a restorer for Bernard Berenson (who, Kenneth Clark said, sat on a pinnacle of corruption), identified herself as the vendor. She did so not in the disinterested cause of scholarship but to claim damages after sensational but unfounded and misleading media reports that fingerprint evidence had shown the drawing to be a Leonardo.
As we reported, aside from the widow’s hearsay claims concerning the ownership of the drawing by the painter/restorer, the drawing otherwise possesses not a shred of recorded history in its supposed five centuries. On the widow’s account (as variously reported by Kemp, by the drawing’s owner, Peter Silverman, and by a journalist selected by Silverman to promote the attribution, Simon Hewitt), Marchig, an unsuccessful artist who had grown rich and acquired a collection of valuable historic works, had declined to say even to his wife when or from whom he had acquired the framed drawing which he is said to have kept in a portfolio.
Jeanne Marchig dangled the possibility that he might have acquired it from Berenson, with whom he had grown close and for whom he had hidden paintings, photographs and documents during the war. Had he done so that would hardly dispel doubts and suspicions but even that possible lifeline to a past now seems unlikely: the drawing’s present owner and Kemp vainly trawled Berenson’s archives at I Tatti for any sign or mention of the drawing. The trail of this supposed Leonardo begins and ends with the Marchigs. Marchig, if his widow is reliable, said nowt and simply had. By coincidence, the widow was born in Warsaw where a book is housed that was later said (unpersuasively for reasons given by Dr Pisarek) to have contained the vellum sheet on which the drawing was made. Professor Kemp thinks the late Jeanne Marchig “a person of great credibility”. The journalist Simon Hewitt reported in the Huffington Post that:
“Jeanne Marchig was born Janina Paszkowska in Warsaw, into a family of doctors and lawyers. She was an only child: her father died in an accident before she was born. Her mother Elzbieta Chrostowska, an amateur wood-carver, took her to Sweden in 1939, where she grew up and married, became Janina Hama. The marriage didn’t last. She met the artist Giannino Marchig on a train between Stockholm and Florence, where he worked as a picture restorer. Berenson and Wildenstein were his top clients. Although a youthful exponent of racy nudes, Giannino was no lady’s man. He lived at home with his mother on the banks of the Arno. He was over 50. Jeanne was an art student. Their age-difference ran into decades. They married. People talked. Talked, too, about Giannino’s wealth. What had he done during the war? Helped hide Berenson’s collection from the Nazis, among other things. Did Berenson give him the Bianca portrait? Jeanne Marchig didn’t know. Or wasn’t saying. They moved to Switzerland. She morphed from a flirtatious livewire into a coquettish Miss Marple of unfluffy shrewdness. Giannino died in 1983. Jeanne published a sumptuous catalogue of her husband’s career and religiously kept the box of pastels he had used to restore the Leonardo.”
PROFESSOR KEMP’S EYE

Above, Fig. 2: The eye of “La Bella Principessa”, top left, and above left (with a superimposed diagram). Top right, an eye drawn by Leonardo (reversed). Above right, an eye featured on a sheet of eyes drawn and reproduced as aids to students and artists in a famous drawing course published in the late 1860s – and later used by the young Picasso.
THE NUB OF CONNOISSEURSHIP DISPUTES IN THE VISUAL ARTS
Martin Kemp and I have recently discussed the eye in “La Bella Principessa” (top left) vis-à-vis the eye by Leonardo (top right) and I am grateful to him for this.
He believes that both eyes are drawn by Leonardo. I (a left-handed draughtsman) hold that the “La Bella Principessa” eye, with its pronounced, almost Cubist, angular and planar construction cannot conceivably have been drawn by Leonardo. There is simply nothing like it in Leonardo’s oeuvre. It is a construct of an alien, more modern kind. Kemp now admits that the unnaturally thick and angular lower lid is problematic but writes: “With the exception of the angularity of the lower lid, which is in an area of some damage, it is consistent (above all the amazingly delicate lashes) with the attached [the eye by Leonardo, top right]. Leonardo’s works of art are not anatomical demonstrations. It’s easy to find ‘anatomical erors’. I find the seizing on such things is to divert the arguments into issues of a peripheral nature in the face of evidence of a non-arbitrary kind.” This is a helpfully clarifying statement, but the suggestion that the eye might have been repaired is new.
In the 2010 Martin Kemp and Pascal Cotte book Leonardo da Vinci “La Bella Principessa” The Profile Portrait of a Milanese Woman, there is no indication given in Cotte’s map (Fig. 3) of repairs to “La bella Principessa” that the eye had been damaged, and Kemp, when comparing the eye with that of Leonardo’s Windsor Castle drawing Portrait of a Woman in Profile (Fig. 5), wrote of it “Even Boltraffio could not achieve this. The structure of the eyelids, the delicate flicks to create the lashes, and the translucent iris of the eye are extremely close on both portraits…” Pascal Cotte goes further, claiming a “distinct and identical logic” with the eye in Leonardo’s portrait of Cecilia Gallerani (The Lady with an Ermine, Fig. 4). Making no reference to injuries or repairs, Cotte specifically points in his diagram (Fig. 4) to the “The juxtaposition of the edge of the lower eyelid with the bottom of the iris”. Speaking generally of the analysed physical evidence of the drawing, Cotte adds “There have been some diplomatic retouchings over the years, but this has not affected the expression and physiognomy of the face to a significant degree or seriously affected the overall impact of the portrait.”
THE PRIMACY OF VISUAL EVIDENCE IN THE VISUAL ARTS
What Kemp sees as a peripheral issue that lacks “non-arbitrary” evidential value, I take to be of the essence in the evaluation and critical appraisal of (visual) works of art. In traditional connoisseurship – an area which Kemp frequently disparages on quasi-scientific professional and leftist political grounds – the test is not to identify similarities (which exist in abundance between authentic works, copies and forgeries) but to discern differences, to discriminate between products of the authentic autograph hand and closely related but variant artefacts.
Of course, Leonardo did not draw every eye as an anatomical demonstration, but nor did he ever draw an eye in ignorance of that crucial feature’s anatomical construction. The eyeball, being an orb, determines the shape and forms of the surrounding soft protective tissue of the lids. Leonardo’s eyes and lids are constructed with curves, not straight lines. With the four images above at Fig. 2, a connoisseur’s ‘eye’ should recognise that even when constructing an eye with straight and not curved lines (as in the lower right demonstration drawing) it is possible to render the visible part of the eyeball conceptually if not literally spherical. That schematic drawing displays greater sculptural and anatomical acuity than does the more laboured and “finished” “La Bella Principessa”. It recognises and describes with three (faint) straight lines, what Leonardo depicts with curves: the line(s) of collision between the bulging soft flesh of the lower eyelid (when the eye is open) and the more taught flesh that is stretched over the cheekbone. In the infrared image at Fig. 6 we can see with crystal clarity how Leonardo saw the structure of the lower eyelid and how he set out this structure in preliminary drawing form. While Leonardo gave fluent anatomically-informed account of eyes, Marchig was insecure in his treatment (see Art’s Toxic Assets – Part II). Had Leonardo complied – against everything else in his output – with an irresistible court demand for a strictly profile treatment of a female subject’s head and torso, as Kemp claims in defence of La Bella Principessa, he would have had the wit and the judgement to render the eye, too, in strict profile. “La Bella Principessa’s” eye – which is smaller – is not drawn in accord with that strict out-of-perspective formal convention. Rather, it strays into looking both outwards and downwards, imparting an insecure, wary, not proud air.
MAPPING THE “RESTORATIONS” OF “LA BELLA PRINCIPESSA”

Above, Fig. 3: The colour coded map that is said to show areas of restoration in “La Bella Principessa”, as published on page 133 of the 2010 Kemp/Cotte book Leonardo da Vinci “La bella Principessa” The Profile Portrait of a Milanese Woman. It is striking how discretely localised are the areas of “restoration”, and how fortuitously the corresponding areas of injury had fallen in the least important parts of the image.
CONFOUNDING THE SIMILAR AND THE DISSIMILAR
Above, Fig. 4: Top, the (true) right eye of The Lady with an Ermine. Above, the eye of “La Bella Principessa”. In this diagram Pascal Cotte, a brilliant engineer, sees confirmation of a common author – even at his arrowed point 2 where Leonardo’s curved demarcation between the eyeball and the lower lid is set against the form-denying straight demarcations in “La Bella Principessa”.

Above, Fig. 5: Left, the eye of Leonardo’s Windsor Castle Portrait of a Woman in Profile (reversed). Right, the smaller, more angular and more sunken eye of “La Bella Principessa”.
A common fault of copyists, pastiche-makers and forgers is to get details correct while missing the larger unified relationships which, collectively, they should constitute. The author of “La Bella Principessa” not only misses the cohering sense of the eye as a ball but even misconstrues the form and anatomical function of particular details. This error testifies to forgery rather than pastiche. We will be showing “La Bella Principessa” to be a “portmanteau work” composed from features drawn from a number of bona fide Leonardos. It can hardly seem a coincidence that the most disqualifying error of drawing in “La Bella Principessa” – the lower eyelid – occurs at the very point where damage is found in the (“prototype”) work which it is most closely said to resemble. At this point the drawing’s author has clearly been required to invent rather than copy or paraphrase. Indeed, in “La Bella Principessa’s” eye we find a progressive falling off of anatomical and artistic credibility from top to bottom: most plausible in “La Bella Principessa” is the somewhat simplifying paraphrase of the upper eyelid. Less plausible is the treatment of the more complex and elusive eyeball and iris. Least plausible of all is the fabricated lower eyelid. Martin Kemp’s claim that by drawing attention to such incompatibility we seek to divert the arguments “into issues of a peripheral nature in the face of evidence of a non-arbitrary kind” is not only unfounded – much material is in train on this attribution – it betrays a technically philistine misapprehension of sound scholarly method. Let us be clear: art, not the devil, lies in artistic detail and these details testify to authorship. We have the clearest possible understanding of how much Leonardo knew and how well he gave expression/record to what he knew/saw. It is for those who would count “La Bella Principessa” as a Leonardo to explain the disparity between its eye and that below at Figs. 7 & 8, which, on Kemp’s account, were both made at the same date.
SPOT THE ODD ONE OUT

Above, Figs. 6, 7 & 8: Top, the eye of “La Bella Principessa”; Centre, the (true) left eye of Leonardo’s La Belle Ferronnière, as seen in an infrared reflectogram by E. Lambert for C2RMF as published in Leonardo’s Technical Practice, Paris, 2014; Above, the (true) left eye of Leonardo’s La Belle Ferronnière, as seen in Pietro Marani’s Leonardo da Vinci – The Complete Paintings, New York, 2000. It is, for reasons given here, inconceivable that both of these eyes could have been produced by Leonardo at the same time – c. 1496.
There is another sense in which Kemp’s espousal of “La Bella Principessa” exposes his art historical method. By drawing attention to “La Bella Principessa’s” many points of direct correspondence with the Windsor Castle profile portrait in terms of overall effects, pentimenti, anatomical details and so forth, the scholar strains credulity. The Windsor Castle portrait is clearly of a mature woman. It was made some 15 years earlier than the supposed portrait of Bianca Sforza who died when a child of fourteen. The Windsor drawing is made in another (and single) medium – silverpoint – in which Leonardo was effortlessly, supremely fluent. “La Bella Principessa”, however, was made in an unprecedented combination of materials on a never or extremely rarely encountered-in-Leonardo support. How likely, then, is it that Leonardo would produce an elaborately finished drawing in an un-encountered mix of graphic and pictorial media and of a type nowhere else encountered in his oeuvre, of a young girl who, on Kemp’s account, was drawn either directly from life or from some other unknown record of her appearance, in commemoration after her death, some fifteen years later, that would, when reversed, produce a near perfect coincidence of proportions, features and, even, pentimenti?
It would, of course, be entirely unremarkable for a forger or pastiche-maker to engineer a similar reversed coincidence of features and traits with a bona fide Leonardo work. A canny forger who happened to be a restorer of old masters – including Leonardo, as was the case with Marchig – would well appreciate the need for evidence of one or two reassuring “campaigns of restoration” in a supposed work of five centuries of age. Marchig’s widow has reportedly claimed that he had indeed conducted restorations on the front of the drawing and on the back of the oak panel to which it was – unprecedentedly and, it is now claimed, irreversibly – glued. Kemp has not discussed, as far as we know, technical evidence that has been discussed by another Leonardo scholar – Cristina Geddo – that the back of the vellum is not blank as it would surely have been had it ever faced the the elaborately illuminated frontispiece of a major book as Kemp claims. For Dr Geddo, it is reassuring that the back of “La Bella Principessa’s” vellum support bears “superimposed numbers…like others written in pen, such as a very pale inscription visible along the upper border of the sheet and the little winged dragon – at least this is what it seems – in the lower left corner. This feature, too, counts in favour of an attribution to Leonardo, who, even though he has never to our knowledge used a parchment support in his work, was in the habit of re-using the paper on which he wrote or drew.” Of course, forgers too re-use old material.
THE AiA: AN OPEN FORUM; A PROFESSIONAL TALKING SHOP; OR, A CONSERVATION-FRIENDLY CLOSED SHOP?
Nothing can bring greater benefit to the art world than free, frank discussions and debate. The annual three-day Hague Congress is organised by a body that addresses the subject of authenticity in art and is titled AUTHENTICATION IN ART. This year’s AiA congress (11-13 May) specifically addresses the voguish museum world hybrid discipline known as Technical Art History, the misapplied and anti-aesthetic scientism of which we have criticised since its earliest days (see, for example, the first post on this site The New Relativisms and the Death of “Authenticity”). Attendees at this year’s AiA congress comprise “art collectors, collection managers, directors of museums and galleries, art dealers, appraisers, connoisseurs, advisors, auctioneers, insurers, investors, lawyers, authors of catalogues raisonnés, restorers, conservators, material scientists and art historians.” This particular critic of Technical Art History will not be speaking even though our proposal for a paper was encouragingly received by a congress organiser who wrote:
“Dear Michael, Thank you. Very valuable to the whole set up of AiA 2016. Get back to you in the coming weeks.”
The proposal had opened:
“Technical Art History is presented as a multi-discipline, international museum-standard professional synthesis that eliminates error and delivers enlightenment when, in truth, it testifies to little more than the ascendency in museums of technicians over curator/connoisseurs. This putsch began with the creation of in-house museum restoration departments where staff restorers could no longer be sacked. The National Gallery in London claims pioneering authorship of the new hybrid discipline and it perfectly reflects the new pecking order.”
We were subsequently “dis-invited” through a form notification to unsuccessful applicants. Among this year’s speakers will be Professor Kemp, a member of the AiA’s advisory board, and Pascal Cotte, of Lumière Technology. Cotte was, as mentioned, co-author with Kemp of the 2010 and 2012 English and Italian editions of a book of advocacy, La Bella Principessa – The Story of the New Masterpiece by Leonardo da Vinci. (Kemp has been critical of Cotte’s recent, go-it-alone book Lumière on the Mona Lisa – Hidden Portraits.) A working group was set up to organise this year’s congress. It is comprised entirely of conservators or conservation scientists. Curators and connoisseurs are not represented. One member of this advisory group was David Bomford, who is presently the Chair of Conservation and Head of European Art at The Museum of Fine Arts, Houston. Formerly, as a senior restorer, Bomford was the architect of the National Gallery’s presently stated cleaning philosophy – which we had discussed in some detail in our proposed congress paper (“…The false assurances of Clark’s aesthetics/science sleight of hand haunt and deform the National Gallery. Its official conservation guide declares restorations to rest on individual restorer’s own aesthetic inclinations…”)
PROFESSOR KEMP’S ART HISTORICAL METHOD
In his 2014 AiA congress paper (“It Doesn’t Look Like Leonardo”) Kemp discussed two other Leonardo upgrading attributions with which he is associated. Namely, the two versions of the Madonna of the Yarnwinder (one of which was restored badly, Kemp once complained, by Marchig) and the massively restored wreck of a panel painting, the Salvator Mundi. His paper’s abstract ran:
“The state of methods and protocols used in attribution is a professional disgrace. Different kinds of evidence documentation, provenance, surrounding circumstances of contexts of varied kinds, scientific analysis, and judgement by eye are used and ignored opportunistically in ways that suit each advocate (who too frequently has undeclared interests). Scientific evidence is particularly abused in this respect. The status of different kinds of evidence is generally not acknowledged, particularly with respect to falsifiability… I will attempt to bring some systematic awareness into this area, which is a necessary first step in establishing some rational protocols. The case studies will be drawn from Leonardo.”
On reading this abstract with its scattergun slurs “opportunistically”, “disgrace” and “undeclared interests”, we laughed out loud. Partly because of the grandiose title – “The 2014 Hague Congress Authentication in Art – What happens when the painting you are buying, selling, investigating, exhibiting, insuring – Turns Out to be a Fake or a (Re)Discovery…” – chosen at a time when Kemp and others had failed to achieve a consensus of support for the drawing he had portentously dubbed “La Bella Principessa”. But also because, as mentioned, two decades earlier we had experienced Kemp’s invective and sneering distaste for traditional connoisseurs whom he sees as “a self-proclaimed (and often class-based) elite whose skills are insulated from systematic scrutiny”.
In his review of the James Beck/Michael Daley book Art Restoration – The Culture, the Business and the Scandal”, the authors – much as with Kemp’s peers today – were found professionally wanting and morally deficient: “…Their problem is that they seem unwilling to acknowledge the status of different kinds of evidence…The slanting of arguments, manipulation of quotations, and rigging of visual evidence may be effective journalism but it is poor history…” A more focussed barb was aimed at artists’ evaluations of conservation treatments: “Stalking throughout their book… is a very particular notion of ‘Art’ and its creators. ‘An Artist’ (ie What Beck and Daley understand as an artist in today’s terms) is adduced as the most important arbiter of the criteria for the treatment of our historical heritage. I am unclear about the identity of this archetypal beast.” Unclear indeed.
Kemp’s professional aversion to the views and judgements of artists is presented as a token of “higher”, more philosophically sophisticated notions of scholarly method and a scientist’s preference for non-judgemental, non-subjective “evidence” within it.
CRITICAL SILENCES
While some are cowed by Professor Kemp’s trademark abusive critical put-downs, others, like the blogger and art “sleeper” hunter, Bendor Grosvenor (21 April), openly admire them. We called Kemp’s bluff in a letter to the THES (2 May 1994):
“…he alleges… a misuse of historical and material evidence. Professor Kemp’s notions of misuse would seem to be singular: he complains, for example, that Professor James Beck and I accepted Charles Heath Wilson’s clear and detailed testimony that Michelangelo had extensively revised his frescoes with glue painting, ‘with unquestioning approval’. This is presented as proof of our ‘lack of discrimination’. But Wilson saw what he saw and said what he said… Does Kemp have any grounds for rejecting Wilson’s record?… Kemp is silent on this evidence. Why? The photographic evidence we supply of restoration-induced injuries is impugned by Kemp as ‘rigged’. It is nothing of the sort – most of it was provided by the restoration authorities themselves… Does Kemp wish to defend that restoration? Is he in possession of any photographs which tell a different story?”
No grounds for rejecting Wilson were offered in reply. No contra-testifying un-rigged photographs were ever produced.
For a fuller account of the spurious charges raised by art conservators and Kemp to Art Restoration, see “Why are picture restorers allergic to appraisal?”, Jackdaw, May/June 2016.
THE 2016 AUTHENTICATION-IN-ART CONGRESS AND ‘DISORDERLY’ SCHOLARSHIP
In this year’s AiA congress paper Kemp returns to his 2014 AiA congress attack on the shortcomings and abuses he perceives in the methodologies and behaviour of all other scholars in the field, albeit in muted form. Today his abstract reads:
“A speech on Technical Art History and the way he [Kemp] implements the research on Leonardo’s La Bella Principessa: the varieties of evidence and arguments, and how reactions to the attribution shed light on the disorderly nature of current methods”.
A clue to where he might be going can be found on his blogsite where he has published a “reworked” version of his 2014 paper that excludes his earlier linking remarks on other Leonardo attributions he supports – “Science and Judgement by Eye in the Historical Identification of Works of Art”.
The methodological schema Kemp outlines and censoriously offers to others seems little more than an overly complicated regurgitation of the tendentious, the self-evident and the true-by-definition. It leans heavily on and misapplies Karl Popper’s famously illuminating discussion of scientific knowledge and methods. Kemp seems to crave an aesthetic equivalent of the decisive Popperian test of scientific “falsifiability”. This is a vain, misdirected quest. Because of the profound differences between appraisal of works of art and the technical analysis of their constituent materials, Kemp is forever complicating and caveating his proposed model method. He compiles tables of hierarchies that are organised into polarising dualities. He is constantly extricating himself from fogs of his own making:
“In this and the following table, I am using the terms ‘scientific’ and ‘art historical’ in a conventional way without intending to signal that they can be isolated in the actual practice of attribution – and certainly not to suggest that the application of scientific analysis necessarily delivers more certainty than art historical evidence. In the actual practice of art history, its isolation from scientific analysis is all too common.”
Which? What? To help orientate us, Kemp devises a table of criteria that are more traditionally “art historical” with the “the most malleable [being] at the top.” But nothing ever comes to rest. Here, “I have added standard kinds of evidence relating to provenance and documentation that are highly constructive.” If baffled by the usage “constructive”, the reader must back-track to an earlier explanation that “The kinds of evidence and explanation that can be subject to various degrees of falsification can be grouped under two headings: constructive and permissive.” Thus, “By constructive I mean those that add positively and accumulatively to the case being made for a specific attribution. By permissive I am signalling those that present no obstacle to the attribution being made, i. e. they offer a nil obstat.”
JUDGEMENT BY EYE
When Picasso was asked what he thought of the philosophical discipline aesthetics, he replied: “Aesthetics is to the artist what ornithology is to birds.” In Kemp, everything is dunked in pseudo-philosophical terminology. Take the simple clear self-explanatory notion “judgement by eye” which he offers in preference to snobby, elitist, class-based etc “connoisseurship”:
“As we have seen, judgement by eye plays a key role in key scientific techniques. Although the most constructive of the kinds of art historical evidence, documentation and provenance, do not rely upon judgement by eye, it is common that this kind of evidence is not available or is less conclusive than we would wish. In many cases judgement by eye necessarily provides the actual starting point, before other kinds of investigation are undertaken. This is often the situation when a previously unknown or unrecognised work first emerges with specific claims attached to it. Let us try to formulate some propositions about judgement by eye in a somewhat Popperian manner”
Why, apart from intellectual snobbery, in a “Popperian” manner? Well, they help Kemp to conclude with the twin observations that “Judgement by eye is malleable in the light of multiple interests”, and “Judgement by eye is falsifiable only by factors outside of itself.” Kemp’s Popperian edifice is, as it were, a perniciously misleading red herring. In truth judgements by eye cannot be equated with falsifiable scientific propositions, they are a different beast – they are critical appraisals. As such they are gambits in a discussion. They can be countered by demonstrably superior, more percipient and persuasive judgements that accord better with the material circumstances and visual facts of a given work of art. Because Kemp sets the hard and “irrefutable facts” of material analysis (many of which, he acknowledges, require judgement by eye) against what he deems the “subjective”, “relative” and “malleable” act of appraisal of the (despised) connoisseur, he misrepresents what is indispensable to proper appraisals of art. Connoisseurship (the term should not frighten or repel us) cannot sensibly be treated as a natural science – properly, rigorously conducted it is an open, competitive adversarial system that is full of checks and balances wherein anything that is proposed may examined, challenged and deposed. Art world abuses certainly exist but they flourish best when legitimate criticisms and demonstrations are blocked and disqualified and critics are ruled out of court. Kemp, who despises the “class-based” connoisseur, does not respond well to criticism and prefers abuse and denigration to straightforward and healthy critical engagement. That is his loss, but also, he being a talented man, it is that of scholarship itself.
AN INTELLECTUALLY OPEN CONFERENCE
When ArtWatch UK, The Center for Art Law, and the London School of Economics Law Department, organised a conference on connoisseurship in London last December (“Art, Law and Crises of Connoisseurship”), one of the papers, “How reliable are today’s attributions in art? The case of ‘La Bella Principessa’ examined”, by Kasia Pisarek, presented a number of the interlocking art historical, aesthetic and technical criticisms she had recently published in the above mentioned Polish scholarly journal Artibus et Historiae.
Because this paper was a strong and detailed rejection of the attribution, we invited Martin Kemp to give a paper. He declined. We then invited Nicholas Turner, an independent scholar and drawings expert who had championed the “La Bella Principessa” drawing before Prof. Kemp. He, also, declined to speak. To represent the restoration-pro-active, attribution-making school of art dealers, we invited Philip Mould. Mr Mould, too, declined to speak. Shortly before the conference, Kemp, Silverman and a Polish art historian, Kasia Wozniak, all lobbied for the “balancing” inclusion in our conference proceedings of the journalist Simon Hewitt who is writing a book with the owner of La Bella Principessa, Peter Silverman – who tells us that the book is on “various aspects of the art market, sometimes highlighted by others’ and my own discoveries”. Hewitt attended the conference and, from the floor, launched an assault on Pisarek’s case – but did so, we later learned, on the borrowed authority of Kemp who had “prepped” him for the occasion on objections he had framed in response to Pisarek’s Artibus et Historiae article. Kemp later submitted his lengthy response to Artibus et Historiae for publication but it was turned down. This article has now been posted on the AiA Congress website. Perhaps, in the interests of scholarly balance, the AiA congress will now also post the article by Dr Pisarek which Professor Kemp aims to rebut? Perhaps the Congress might also consider posting our own initially valuable-to-proceedings but later rejected paper on Technical Art History?

Connoisseurship in Action and in Peril
“WHEN THE FIRST catalogue of the Ashmolean Museum’s Sculpture collection (in three volumes) was undertaken more than twenty-five years ago, the present author decided to exclude works made before 1540…”
“…The decision was partly determined by the quantity of the material but also in recognition of the special attention that the finest of the small bronzes given and bequeathed by Charles Drury Fortnum deserved. It is indeed because of these that the Ashmolean’s sculpture collection is the most important in the United Kingdom after that of the Victoria and Albert Museum, London…”

Above and below: The ‘Fortnum Venus’, attributed to Francesco Francia or his circle. c. 1500-05. Bronze, 26.1 cm. high. (Ashmolean Museum, Oxford).


Above, detail of St Jerome, by Cosimo Tura. c.1470. Panel, 101 by 57.2 cm. (National Gallery, London).
“The first of Jeremy Warren’s three volumes under review here includes these very figures. One of them is the
exquisite Venus associated with the Bolognese painter and goldsmith Francesco Francia (cat. No.20). It is one of the earliest responses in the Renaissance to the antique female nude, and perhaps belonged to a narrative group for, as her drapery falls, her hand is cupped as if to receive the apple from Paris…”
“…In conclusion it should be noted that the cataloguing of the permanent collection is not now often considered an essential part of the curator’s job. Any museum director who is chiefly an impresario is inevitably attentive to fashionable ideas and taste, whereas the cataloguer of a permanent collection is bound to give his or her attention to neglected artists, and to works by artists in which they are not initially interested, but which beg the question as to why the appealed to their predecessors – collectors, scholars and curators long deceased. This provides an antidote not only to the narrow outlook of the popular exhibition machine, but to that of academic institutions where scholars, having achieved promotion by imitating their seniors, are obliged to compete in appealing to the young consumers upon

PERMANENT EVOLUTION – A JOB FOR LIFE
“Museums have become places where we take part in social as well as learning activity. It is easy to be cynical about
the impact of the café, restaurant or shop spaces on the culture and character of museums, but such facilities have made museums less daunting, more welcoming and more open to general visitors. However, such [democratization] needs to go deeper than the provision of opportunities to purchase or to consume.”
NICHOLAS SEROTA, the director (- since 1988) of the Tate, at the Leeum Samsung Museum of Art in Seoul.




HOW ART HISTORIANS CAN BE FOOLED BY CONDITION
“One of the most influential books in the twentieth-century art history was Erwin Panofsky’s Studies in Iconology. In this seminal work, the very latest German approaches and method were presented to an Anglo-Saxon audience for the first time. One of the dazzlingly learned chapters was devoted to the figure of Cupid wearing a blindfold, and Panofsky showed how this theme could be traced back to the writings of the medieval moralists. For thinkers of this Christian stamp, lovers were metaphorically blind, since they were ‘without judgement or discrimination and guided by mere passion’. But later, in the Renaissance, ‘moralists and and humanists with Platonizing leanings’ contrasted the figure of the blindfold Cupid with another kind of…”

“…Although Bode was extremely learned in many branches of art history and had his information always ready – he had little need of written notes and photographs – he was no scholar in the true sense. He was more fond of action than reflection, and was far from having a just and objective mind. Moreover, the distracting practice of uninterrupted daily work hindered a comprehensive synthesis of realization. The deepest motive of the scholar, namely, disinterested love of truth, could not function productively in a nature always resolutely aiming for effectiveness and visible results. Bode was utterly unphilosophical, he considered no affair from more than one side. He saw black or white, good or bad, advantageous or inimical; he knew no intermediary steps. To forsee obstacles, to fear, to guard against them was not his way. Consequently he became angry as soon as he encountered opposition. He made more mistakes by acting than by failing to act. He was a hunter, not an angler.”

“…Anyway, getting back to the book that was sent to me, its title was rather grand and pompous: La bella Principessa – the beautiful princess. Or, as I knew her, ‘Bossy Sally from the Co-op’. I’m a bit unsure of how to talk of this because the book was written by an eminent Oxford professor and must have been quite an effort. I don’t want to ruffle any feathers or cause problems but I nearly swallowed my tongue on reading its supposed value – £150 million! It would be crazy for a public body to pay such a sum. So I feel the need to say something about it.
“The drawing is thought by some to be a work by Leonardo da Vinci, but it does divide opinion and it wasn’t included in the National Gallery’s Leonardo show of 2011, a show which I thought was really well done except for it being staged ‘underground’ in the Sainsbury Wing basement…
“I drew this picture in 1978…It was done on vellum, quite a large piece to find unfolded and without crease lines. I did it on vellum because at that time I couldn’t make old paper yet…The first thing I had to do was sand off the writing with 600-grit wet and dry paper. That done, it looked too new for anything old to look right on it, so I turned it over and did the drawing on the other side. That is why the drawing is done on the hair side of the vellum instead of the much-preferred ‘flesh side’. The texture of the sanding should still seen on its reverse.
“As I said, the face is of 1970s vintage, and I think that shows in the drawing…The drawings of Leonardo and Holbein especially have always impressed me with their fineness of line and detail, and in my view they must have been done under some magnification…The vellum is mounted on an oak board…before drawing on it, the vellum was stuck to the backboard with cabinet maker’s pearl glue, so it needed to be under a weighted press for a while to allow the glue to go off without ‘cockling’ the vellum. ‘Cockling’ is the effect you see on paper when you try to paint a watercolour without soaking and stretching the paper first. On vellum the dampness looks like blisters or a cockle bed on the shore. It’s caused by the water content of the glue, so the thing needs to be under a heavy press to dry it flat.
“After a bit of experimentation, and just to prove a point to myself, I lightly traced the drawing I’d invented onto the vellum (I’m sure the graphite can still be detected) and started to draw the image in hard black chalk – carbon black in gum arabic – using a pair of jeweller’s magnifying glasses. It took some time to get used to working like that, and I had to go to back to practising on papper for a while so as not to bugger things up…
“It was done in just three colours – black white and red – all earth pigments based in gum arabic, with the carbon black mostly gone over with oak gall ink. To be a bit Leonardo-like or even Holbein-like – they were both left-handers – I put in a left-hander’s slant to it…The Leonardo book [“La Bella Principessa ~ The Story of the New Masterpiece by Leonardo da Vinci”, By Martin Kemp and Pascal Cotte, with contributions by Claudio Strinati, Nicholas Turner and Peter Paul Biro] seems to put great store by the apparent leftyness of the drawing, but it can be shown up very easily. With the face on the vellum facing left, just turn the drawing clockwise to face her skyward, and hatch strokes from profile outwards in the normal manner…Incidentally, the book points out a palm print on the neck area, just the spot a right-hander doing an impersonation of a left-hander might rest their hand whilst doing the background hatching.
“Although I am no Oxford professor, I could list umpteen reasons for not thinking this drawing to be by leonardo…
The book mentions several holes on one margin as evidence that it has been bound into a volume, and also mentions some later ‘restoration’. I did not do these things, and don’t know who did, or where it went on its later travels. Looking closely at the picture in the book, it looks to have had the left margin peeled back an inch or so and has been restuck, not very well, especially at the bottom left. Could this be from when the left margin was pierced and roughly re-cut by someone else?
“I sold it for less than the effort that went into it to a dealer in Harrogate in late 1978 – not as a fake, or by ever claiming it was something it wasn’t. I can’t really say any more on it. At least it may now be known for what it is.”
~ SHAUN GREENHALGH – A Forger’s Tale, Published by ZCZ Editions in 2015
In the past it was customary for scholars to advance claims of attribution for particular works of art in scholarly journals and then wait to see how peers and colleagues responded to their evidence and arguments. Increasingly, we are seeing co-ordinated promotional campaigns of advocacy by players and owners who eschew venues of debate and sometimes denigrate sceptics and opponents. We invited two of the leading advocates of “La Bella Principessa’s” Leonardo’s authorship – Martin Kemp and Nicholas Turner – to speak at our recent conference on connoisseurship. Both declined. Neither our post of January 2014 (“Art’s Toxic Assets and a Crisis of Connoisseurship ~ Part II: Paper – sometimes photographic – Fakes and the Demise of the Educated Eye”) nor our colleague Kasia Pisarek’s article “La Bella Principessa: Arguments against the attribution to Leonardo” that was published in the June 2015 issue of the scholarly journal artibus et historiae have been challenged in print.

The da Vinci Detective: Art Historian Martin Kemp on Rediscovering Leonardo’s Tragic Portrait of a Renaissance Princess – an ARTINFO Interview by Andrew M. Goldstein, 17 October 2011. Extracts:
…[Andrew Goldstein] “They weren’t the only ones to differ on the attribution of the painting, and when you first announced that you believed it to be a Leonardo, a lot of people disagreed. One museum director even told the Telegraph’s Richard Dorment, anonymously, that it was a “screaming 20th century fake, and not even close to Leonardo himself.” Has there been any reversal since then?
[Martin Kemp] “I don’t know who this anonymous person was, but we carbon-dated the parchment and that eliminates it from being a screaming modern forgery. If it were a forgery, it used things that we’ve only recently discovered about Leonardo’s technique in the last 20, 30 years. The fact that it was owned by Giannino Marchig takes it outside the period when it could be a forgery, knowing what we know now, so that’s not an option. The ultra-violet turns up retouching, and it’s very clear it has been heavily restored, but most objects 500 years old, including the “Salvator Mundi”, which is the new picture being shown in the National Gallery.
[…] “One thing that critics of your ‘Principessa’ attribution tend to bring up is the involvement in your research of Peter Paul Biro, a fingerprint expert whose credibility was questioned. What is your opinion of him?
“Well, Biro I knew of as someone who’d specialized in fingerprints and paintings, so we asked him to look at the fingerprint that is in the upper left side of the ‘Bella Principessa.’ I had data on finger prints and finger marks in other Leonardo paintings, and he said one of these matched – not astoundingly, because it’s just the tip of a finger, and one doesn’t rely on fingerprints on vellum. It wouldn’t convict anybody in a court of law. You need more than that. So he did a limited job here, and we didn’t depend too much on that evidence. The press liked it, of course because it was cops and robbers stuff.
“I would not now probably say much about it at all, because on reflection I don’t think we have an adequate reference bank of Leonardo fingerprints. I’ve talked to fingerprint specialists, and they typically require a full set of reference prints. We don’t have that for Leonardo. My sense is – and this is Pascal’s sense, too – that it’s probably premature, given what we know about Leonardo’s fingerprints, to come up with matches at all. But the job Biro did was perfectly straightforward. There were no grounds for dishonesty. Peter Paul Biro is suing the New Yorker*, but I can’t comment at all upon the court case because that’s about things that I know nothing about, so it’d be totally improper. But he did work for us, which I now, let’s say, place less reliance on, simply because, on reflection, I think the fingerprint evidence is rather slippery.
“Because of the work you have done to bring the ‘Principessa’ into the fold of acknowledged Leonardos, some say you have crossed from the realm of scholarship to something more like advocacy. How do you explain your passion for the portrait?
“I would say that one of the differences between being a historian of art and being a scientist, as I was trained, is that you’re dealing with objects that are deliberately communicating with something other than just our intellect. So, for me, it’s not a dry process. You begin with the feeling it’s special, and if it stands up to the research, you end with the feeling that it’s special, and I make no apology for that. I’ve been critized as acting as an advocate for it, but if I’m writing, as I am in ‘Christ to Coke’, about the ‘Mona Lisa’, I’m an advocate for that too, because it’s a miraculous picture. Also, when I’m writing about the Coke bottle, I’m not an advocate for Coke as a drink. I hate it. But it’s one of the all-time great
bits of product design and I’m happy to say that.”
“*THE MARK OF A MASTERPIECE” by David Grann, The New Yorker, 12 July 2010 ~ Extracts:
[1] “But he [Martin Kemp] also relies on a more primal force. ‘The initial thing is just that immediate reaction, as when we’re recognizing the face of a friend in a crowd,’ he explains. ‘You can go on later and say “I recognize her face because the eyebrows are like this, and that is the right colour of her hair,” but, in effect, we don’t do it like that. It’s
the totality of the thing. It feels instantaneous.'”
[2] “Moreover, according to [the curator of Drawings at the Metropolitan Museum of Art, Carmen] Bambach, there was a more profound problem: after studying an image of the drawing [La Bella Principessa] – the same costume, the same features, the same strokes that Kemp examined – she had her own strong intuition. ‘It does not look like a Leonardo’, she said.”
[3] “When such a schism emerges among the most respected connoisseurs, a painting is often cast into purgatory. But in January, 2009, Kemp turned to a Canadian forensic art expert named Peter Paul Biro who, during the past several years has pioneered a radical new approach to authenticating pictures. He does not merely try to detect the artist’s invisible hand; he scours a painting for the artist’s fingerprints, impressed in the paint on the canvas. Treating each painting as a crime scene, in which an artist has left behind traces of evidence, Biro has tried to render objective what has historically been subjective. In the process he has shaken the priesthood of connoisseurship, raising questions about the nature of art, about the commodification of aesthetic beauty, about the very legitimacy of the art world.Biro’s research seems to confirm what many people have long suspected: that the system of authenticating art works can be arbitrary and, at times, a fraud.”
[4] “Biro asserted that he had uncovered the painting’s ‘forensic provenance,’ telling a reporter, ‘The science of fingerprint identification is a true science. There are no gray areas.’ Having developed what he advertised as a ‘rigorous methodology’ that followed ‘accepted police standards,’ he began to devote part of the family business to authenticating works of art with fingerprints—or, as he liked to say, to ‘placing an artist at the scene of the creation of a work.'”
[5] “But the International Foundation for Art Research, a nonprofit organization that is the primary authenticator of Pollock’s works, balked, saying that Biro’s method was not yet ‘universally’ accepted.
[6] “In 2009, Biro and Nicholas Eastaugh, a scientist known for his expertise on pigments, formed a company, Art Access and Research, which analyzes and authenticates paintings. Biro is its director of forensic studies. Clients include museums, private galleries, corporations, dealers, and major auction houses such as Sotheby’s. Biro was also enlisted by the Pigmentum Project, which is affiliated with Oxford University.”
[7] “Biro told me that the divide between connoisseurs and scientists was finally eroding. The best demonstration of this change, he added, was the fact that he had been commissioned to examine ‘La Bella Principessa’ and, possibly, help make one of the greatest discoveries in the history of art.”
[8] “After he first revealed his findings, last October, a prominent dealer estimated that the drawing [‘La Bella Principessa’] could be worth a hundred and fifty million dollars. (The unnamed ‘lady’ who had sold it at Christie’s for less than twenty-two thousand dollars came forward and identified herself as Jeanne Marchig, a Swedish animal-rights activist. Citing, among other things, the fingerprint evidence, she sued the auction house for ‘negligence’ and ‘breach of warranty’ for failing to attribute the drawing correctly.)”
[9] “Ellen Landau, the art historian, said that she was ‘absolutely convinced’ that the paintings were by Pollock. Biro was sent a photograph of a fingerprint impressed on the front of one picture. He identified six characteristics that corresponded with the fingerprint on the paint can in Pollock’s studio—strong evidence that the work was by Pollock. But, as more and more connoisseurs weighed in, they noticed patterns that seemed at odds with Pollock’s style. Meanwhile, in sixteen of twenty art works submitted for analysis, forensic scientists discovered pigments that were not patented until after Pollock’s death, in 1956. At a symposium three years ago, Pollock experts all but ruled out the pictures. Ronald D. Spencer, a lawyer who represents the Pollock-Krasner Foundation, told me, ‘Biro can find all the fingerprints he wants. But, in terms of the marketplace, the Matter paintings are done. They are finished.'”
[10] “Reporters work, in many ways, like authenticators. We encounter people, form intuitions about them, and then attempt to verify these impressions. I began to review Biro’s story; I spoke again with people I had already interviewed, and tracked down other associates. A woman who had once known him well told me, ‘Look deeper into his past. Look at his family business.’ As I probed further, I discovered an underpainting that I had never imagined.”
[11] “During the eighties and early nineties, more than a dozen civil lawsuits had been filed against Peter Paul Biro, his brother, his father, or their art businesses. Many of them stemmed from unpaid creditors. An owner of a picture-frame company alleged that the Biros had issued checks that bounced and had operated ‘under the cover’ of defunct companies ‘with the clear aim of confusing their creditors.’ (The matter was settled out of court.) As I sifted through the files, I found other cases that raised fundamental questions about Peter Paul Biro’s work as a restorer and an art dealer.
[12] “Biro refused, multiple times, to divulge where he had obtained either of the paintings. According to the Wises, Biro insisted that the person who sold him the paintings was in Europe, and that it was impossible to contact him.
[13] “Sand sought proof of a financial transaction—a check or a credit-card payment—between Biro and Pap. Biro, however, said that he had obtained them in exchange for two musical instruments: a Steinway piano and a cello.
[14] “Sand was incredulous: ‘Is Mr. Pap a music dealer or is he an art dealer?’ After Biro could not recall where he had originally purchased the cello, Sand suddenly asked him, ‘You ever been convicted of a criminal offense, sir?’
‘No.’
‘You are certain of that?’
‘Yes,’ Biro said.”
[15] “Throughout the trial, the Biros and their attorneys maintained that the two paintings sold to the Wises were authentic, but to make their case they presented an art expert who was not a specialist on Roberts, or even on Canadian art. On September 3, 1986, the court found in favor of the Wises, and ordered Peter Paul and Geza Biro to pay them the seventeen thousand dollars they had spent on the pictures, as well as interest.”
[16] “Lawsuits had piled up against Peter Paul Biro and his family business. In two instances, there were allegations that art works had vanished under mysterious circumstances while in the care of Peter Paul. In one of the cases, Serge Joyal, who is now a senator in Canada, told me that he left a nineteenth-century drawing with the Biros to be restored. Before he could pick it up, Peter Paul notified him that it had been stolen from his car and that there was no insurance. Biro, however, never filed a police report, and Joyal says that Biro pleaded with him to wait before going to the authorities. During their conversations, Joyal says, Peter Paul acted evasive and suspicious, and Joyal became convinced that Biro was lying about the theft. As Joyal put it, ‘There was something fishy.’ Though Peter Paul said that there was nothing ‘suspect’ about his behavior, and that he should not be held liable, the court awarded Joyal seven thousand dollars, plus interest.”
[17] “Within Montreal’s small art world, there were whispers about Peter Paul Biro and his father. But the lawsuits appear to have attracted virtually no public attention. In 1993, Peter Paul Biro filed for bankruptcy, and he never paid many of the judgments against him, including what he owed the Wises and Joyal. Lipsz’s lawyer said of Biro, ‘He oiled his way out of that whole thing. . . . He got away scot-free.'”
[18] “Biro was part of an effort to launch a venture named Provenance, which would provide, as he put it, the ‘clever strategy’ necessary to sell ‘orphaned’ paintings for tens of millions of dollars. According to a business prospectus, marked confidential, Provenance would acquire art works that had been forensically validated by Biro and several colleagues, and sell them in a gallery in New York City. The company chose a thumbprint for a logo.”
[19] “Provenance was cleverly tapping into the public’s desire to crack open the art world, offering the tantalizing dream that anyone could find a Pollock or a Leonardo or a Turner languishing in a basement or a thrift shop. The company combined the forensic triumphalism of ‘C.S.I.’ with the lottery ethos of ‘Antiques Roadshow.’ (An associate producer at ‘Roadshow’ had already sent Biro an e-mail about possibly doing a segment on the Parkers’ ‘unbelievable discovery.’)
[20] “Biro previously had been suspected of creating an investment scheme around a seemingly precious object, with the promise that it would eventually reap huge profits. In the late nineteen-nineties, he persuaded a Canadian financial adviser, Richard Lafferty, who is now dead, to invest in a venture to authenticate and sell a work purportedly by Raphael’s disciple Perino del Vaga. Three of Lafferty’s colleagues confirm the story, as do letters, memorandums, and other documents.”
[21] “By the fall of 2005, Ken Parker had begun to look into the people behind Provenance. It turned out that Tod Volpe, in the nineties, had defrauded his art clients, including Jack Nicholson, of nearly two million dollars, and had served two years in prison. Parker discovered that one of Volpe’s principal partners in Provenance was also an ex-con, who had done time for tax evasion and for running a drug-smuggling operation in the United States. (Volpe told me, ‘We all have skeletons in our past.’) Parker confronted Biro, who, in a subsequent e-mail, told Parker that he had ‘severed all communication with Volpe.’”
[22] “And only months after rescinding his request for money he asked the Parkers to fund another new project: a privately endowed department for him and a colleague at Oxford University. ‘Naturally it is 100% tax deductible,’ Biro wrote, in an e-mail. ‘Those who support the foundation of a bold and new department for us at Oxford will have their name on a plaque or have the department named after them such as “The Ken Parker Department for Forensic Art History.” Sounds cool?'”
[23] “When a forgery is exposed, people in the art world generally have the same reaction: how could anyone have ever been fooled by something so obviously phony, so artless? Few connoisseurs still think that Han van Meegeren’s paintings look at all like Vermeers, or even have any artistic value. Forgers usually succeed not because they are so talented but, rather, because they provide, at a moment in time, exactly what others desperately want to see. Conjurers as much as copyists, they fulfill a wish or a fantasy. And so the inconsistencies—crooked signatures, uncharacteristic brushstrokes—are ignored or explained away. “
[24] “In the case of ‘La Bella Principessa,’ Biro did not handle the drawing, and was sent multispectral images from another laboratory, which he then developed and enhanced. Martin Kemp, the Leonardo scholar, told me, ‘In terms of what Biro did for us, I have absolutely no problems with any potential ethical issues.’ He emphasized that his opinion of the drawing did not depend on the fingerprint evidence: ‘I’m entirely confident that it is by Leonardo.'”
[25] “A final verdict on whether ‘La Bella Principessa’ is genuine may not be reached for years, but more and more connoisseurs have voiced doubts. Skeptics express surprise that there is no apparent historical record for the drawing, given that Leonardo was one of Italy’s most famous painters during the Renaissance. They note that vellum lasts for centuries, and that it would be easy for a forger to obtain old sheets. Many of the critics share the view of the Met’s Carmen Bambach: it just doesn’t look like a Leonardo. ARTnews, which has reported on Wertheim’s findings, recently interviewed Klaus Albrecht Schröder, the director of the Albertina Museum, in Vienna. ‘No one is convinced it is a Leonardo,’ he said. David Ekserdjian, an expert on sixteenth-century Italian drawings, wrote in The Burlington Magazine that he ‘strongly suspects’ it is a ‘counterfeit.’ Other art critics have suggested that Kemp has succumbed to a fantasy.
[26] “Whereas Biro had once spoken of the absolute objectivity and infallibility of fingerprint analysis, he now sounded more like a connoisseur than like a scientist. ‘I’m trying to define, for example, what is the point that something becomes a matter of interpretation,’ he said. ‘In other words, where is that line? O.K., on the one hand, fingerprint practitioners state that fingerprint identification is a science. I’m more toward the other side, where I’m convinced by my own personal experience that it is very much like connoisseurship, because of . . . things I see they don’t.’”
[27] “I asked him whether he might have been wrong in suggesting that Leonardo had ever touched ‘La Bella Principessa.’ He looked up at the sky and said, ‘It’s possible. Yes.’”
In July 2011 ADWEEK reported that Biro had sued The New Yorker and David Grann for $2 million on twenty-four charges of false and malicious defamation – Forensic Art Expert Peter Paul Biro Sues New Yorker for Deformation. The action failed on every count (see “Art Authenticator Loses Defamation Suit Against The New Yorker“).
CODA: Faking A Picasso and a Provenance
In June last year, we and Martin Kemp were asked (separately) by the Daily Mail to comment on a claimed Picasso painting that supposedly had been found by an artist among his late mother’s belongings in an old suitcase in the loft – “Is this a long-lost Picasso? Painting that bears a strong resemblance to Cubist’s work is discovered rolled up in a battered suitcase that hasn’t been touched in 50 years” – the Mail reported:
“…Last month, a 1955 Picasso painting – Les Femmes d’Alger – broke auction records when it sold at Christie’s for a staggering £115 million.
“Art expert Michael Daley told MailOnline his first instinct was that the painting was not a Picasso. ‘The colours and all of that are right but I think there is too much incidental detail and not enough decisive interest or exploration. This is
all sharp edges and brown tones and what-have-you, but it doesn’t have the driving sense of Picasso getting at something, getting at a figure trying to see something about it. This is more decorative. It can be no more than an instinctive first impression, but to me it doesn’t look like a Picasso Cubist painting from that period.’
“Martin Kemp, emeritus professor of art history at Oxford University, was also skeptical. Prof Kemp said: ‘It’s pretty close to Picasso’s portrait of Daniel-Henry Kahnweiler, the dealer whom he painted in 1910 and is in the Art Institute of Chicago. This looks to be a relatively competent but not excellent near copy of it – the signature is very dodgy. Without doing a full art historical analysis – and I’m not a Picasso expert – I would say someone has made a variant of the Picasso portrait. Also the signature with the rounded S’s doesn’t seem to correspond to Picasso’s way of signing and thirdly the canvas doesn’t look quite right for Picasso of that period.
But I hope for the sake of the owner that I’m wrong.'”

On 6 July 2015 The Scotsman disclosed that the discovered ‘Picasso’ was a fake (“Picasso painting in Fife attic ‘a hoax’”). The faker, Dominic Currie, reportedly described his purported-Picasso (which had been about to be inspected by Christie’s) as “a piece of performance art [made] in order to raise awareness of the struggling artists in Scotland.” The fake is now being offered for sale on the website of a picture restoration business.
Michael Daley. 10 December 2016.
12 December 2016. Postscript: “Bode gave an opinion on art works from many fields, on Netherlandish painting of the seventeenth century, on Italian sculpture, Persian rugs, majolica, German wood sculpture, and many other things. His writings were for him always a means to an end, and were frequently controversial and advocatory. Almost always he judged correctly, and at the time he expressed them, his communications were of significance and infinitely enriched knowledge in many fields. But the tragic fate of the ‘connoisseur’ lies in the fact that yesterday’s new, strikingly accurate definitions are today’s common properties and banalities, that only the mistakes linger in the memory under the name of the originator.”
