“Leonardo scholar challenges attribution of $450m painting”

Dalya Alberge reports in the Guardian that a Leonardo scholar, Matthew Landrus, believes most of the upgraded Salvator Mundi was painted by a Leonardo assistant, Bernardino Luini.

THE LUINI CONNECTION

In her Guardian article, “Leonardo scholar challenges attribution of $450m painting”, Dalya Alberge further reports that the upgraded version of the Salvator Mundi that Matthew Landrus has de-attributed to Leonardo’s assistant, Bernardino Luini, is the very painting that was attributed to Luini in 1900, when acquired by Sir Charles Robinson for the Cook collection.

Above, Fig. 1: Left, the Salvator Mundi that was bought for $450m as a Leonardo for the Louvre Abu Dhabi in November 2017 as it was seen in 2007 when only part-repainted and about to be taken to the National Gallery, London, for a viewing by a small group of Leonardo scholars who are said to have been sworn to secrecy. (For the many subsequent changes to the painting see our “The $450m New York Leonardo Salvator Mundi Part II: It Restores, It Sells, therefore It Is” and Figs. 4 to 6 below.) Above, right: A detail of the National Gallery’s Luini Christ among the Doctors.

BIG CLAIMS ON INCOMPLETE EVIDENCE

Even after being sold twice (in 2013 and 2017) for a total of more than half a billion dollars, the painting’s 118 year long journey from a Luini to a Leonardo and now back to Luini again, remains a mystery: no one has disclosed when, from whom and where the painting is said to have been bought in 2005. Professor Martin Kemp recently disclosed that the work was bought for the original consortium of owners “by proxy”. Long-promised technical reports and accounts of the provenance have yet to appear and keep receding into the future. These lacunae notwithstanding, the painting is scheduled to be launched at the Louvre Abu Dhabi in September, and also to be included in a major Leonardo exhibition at the Paris Louvre in 2019.

THE ROLE OF LEONARDO’S ASSISTANTS IN THE LOUVRE ABU DHABI SALVATOR MUNDI

As Dalya Alberge reports, a number of Leonardo scholars have contested the present Leonardo attribution and held the work to be largely a studio production that was only part-painted by Leonardo himself. Frank Zöllner, a German art historian at the University of Leipzig and author of the catalogue raisonné Leonardo da Vinci – the Complete Paintings and Drawings, believes it to be either the work of a later Leonardo follower or a “high-quality product of Leonardo’s workshop”. Carmen Bambach, of the Metropolitan Museum of Art, holds it to have been largely the work of Leonardo’s assistant Giovanni Antonio Boltraffio. One scholar, Jacques Franck, suggested in a 29 November 2011 interview in the Journal des Arts that an attribution to either Luini or Leonardo’s late assistant (and effective ‘office manager’) Gian Giacomo Caprotti, called Salai or Salaino seemed plausible and persuasive. More recently, in January 2018, he tipped to Salai as the author because of strong similarities revealed by penetrating technical imaging examinations – see Figs. 2 and 3 below and “Salvator Mundi LES DESSOUS DE LA VENTE DU SIECLE”.

Above, Fig. 2: Left, an infra-red reflectogram of the Louvre Abu Dhabi Salvator Mundi; above, right, an infra-red reflectogram of Salai’s Head of Christ, signed and dated 1511, Pinacoteca Ambrosiana (Milan).

Above, Fig. 3: An infra-red reflectogram detail of the Louvre Abu Dhabi Salvator Mundi. Jacques Franck writes: “This close-up view of the Fig. 2, left, document, reveals in the Saviour’s face, neck and head, the same typical underlying sketching-out technique using very thick dark lines to define the preliminary contours and modelling that are seen in Fig. 2, right. None of this underlying graphic/roughing out process is ever encountered in original Leonardo painting where the graphic/painterly stages are more subtle.”

Above, Fig. 5: Left, the former Cook collection painting’s face as in 2005; right, the face, as transformed over twelve years by Modestini, when presented for sale at Christie’s, New York, in November 2017.

Alberge’s current Guardian article, “Leonardo scholar challenges attribution of $450m painting” has gone viral – see for example: CNN’s “Leonardo’s $450M painting may not be all Leonardo’s, says scholar”, and the ABC (Spain) “Crecen las dudas sobre la autoría del «Salvator Mundi» de Leonardo”.

In the CNN report, it is said that:

“Others are in less doubt. Curator of Italian Paintings at London’s National Gallery, Martin Kemp, sent the following statement to CNN Style by email: ‘The book I am publishing in 2019 with Robert Simon and Margaret Dalivalle (…) will present a conclusive body of evidence that the Salvator Mundi is a masterpiece by Leonardo. In the meantime I am not addressing ill-founded assertions that would attract no attention were it not for the sale price.’”

We make the following observations. Although Professor Martin Kemp is not a curator at the National Gallery he does seem to have been considered at one point as a possible co-curator of the National Gallery’s 2011-2012 Leonardo exhibition, which, in the event, was curated solely by the Gallery’s own then curator, Luke Syson, who is now at the Metropolitan Museum of Art. Syson drew heavily for his 2011 catalogue entry on the painting on the researches of one of the owners of the Salvator Mundi, the New York art dealer, Robert Simon: “This discussion anticipates the more detailed publication of this picture by Robert Simon and others. I am grateful to Robert Simon for making available his research and that of Dianne Dwyer Modestini, Nica Gutman Rieppi and (for the picture’s provenance) Margaret Dalivalle, all to be presented in a forthcoming book.” That book has now been coming for some time. First promised by the National Gallery in 2011, it was more recently promised for 2017, and then for this year, and now, for next year – and possibly in time for inclusion in the catalogue of the Paris Louvre’s planned major 2019 Leonardo exhibition?

Professor Kemp also promised a conclusive body of evidence for his attribution to Leonardo of the drawing he dubbed “La Bella Principessa”. In his 2012 book Leonardo’s Lost Princess, Peter Silverman, the owner of “La Bella Principessa”, wrote: “Martin believed that the fingerprints [compiled by the now discredited fingerprints expert Peter Paul Biro], though not conclusive on their own, added an important piece to the puzzle. He wrote to me, ‘This is yet one more component in what is as consistent a body of evidence as I have ever seen. I will be happy to emphasize that we have something as close to an open and shut case as is ever likely with an attribution of a previously unknown work to a major master. As you know, I was hugely skeptical at first, as one needs to be in the Leonardo jungle, but now I have not the slightest flicker of doubt that we are a dealing with a work of great beauty and originality that contributes something special to Leonardo’s oeuvre. It deserves to be in the public domain.’” In the event, the “La Bella Principessa” drawing did not enter the public domain. Unlike the Salvator Mundi, which sold for $450m, it was not included in the National Gallery’s 2011-2012 Leonardo exhibition and it presently remains, so far as we know, unsold, in a Swiss free port.

Kemp’s present lofty disinclination to address “ill-founded assertions that would attract no attention were it not for the sale price” marks a change of policy. Last year, immediately ahead of the sale that produced the astronomical price of the Salvator Mundi, Kemp was happy to engage polemically with those who rejected the Salvator Mundi’s Leonardo attribution. As he has recently disclosed: “I was approached by the auctioneers to confirm my research and agreed to record a video interview to combat the misinformation appearing in the press – providing I was not drawn into the actual sale process.”

SCHOLARS’ NEED FOR FULL AND DETAILED REPORTS AND FOR OPEN DEBATES

Above, Fig. 6: Left, the small-scale published (infra-red) technical image of the Salvator Mundi; centre, the painting as exhibited in 2011-2012 as a Leonardo at the National Gallery; right, the painting as presented for sale at Christie’s, New York, in 2017.

Much remains to be examined with this restoration-transformed but still, effectively, unpublished work where the promised reports on technical examinations and provenance seem perpetually trapped in the post like Billy Bunter’s postal order. Note in Fig. 6 above, for example, the radical changes made to the true left shoulder draperies; to the orb and the sole of the hand that holds it; and, above all, to the face. We must hope that the painting’s new owners will encourage the old 2005 consortium of owners to publish their privately commissioned researches as soon as possible. In general terms, it would be a much better thing if new and elevating attributions were once more published by single scholars, taking full responsibility in a scholarly publication, so that the case for a work’s re-attribution might be examined widely and discussed openly on a fully informative account and presentation of technical evidence and history of provenance. The recent tendency for owners to hold and selectively part-release researches during promotional campaigns of advocacy is not conducive to best scholarly practice.

Professor Martin Kemp and ArtWatch – Part 1: Twenty-four years of abuse on photo-testimony


Fake or Fortune: Hypotheses, Claims and Immutable Facts

We have received two communications on “La Bella Principessa”, which drawing some take to be by Leonardo da Vinci. One came from the work’s owner, the other from a disinterested scholar in confirmation that the work could not, for reasons of arithmetic and plain physical facts, have been made by Leonardo for inclusion in a book.

THE DRAWING

Above, Fig. 1: The full vellum sheet of the proposed Leonardo drawing “La Bella Principessa”.

THE DRAWING’S CLAIMED ORIGIN

This drawing was presented anonymously to the world in 1998 without authorial ascription and without an atom of provenance. When claims of autograph Leonardo authorship were made after barely a decade, it became necessary to fill a five-hundred years long void of records in order to dispel suspicions of forgery or pastiche. In 2010 Professor Martin Kemp bundled together what he held to be a “barrage of evidence – stylistic, historical or technical” that somehow provided collectively what no individual parts constituted: proof that Leonardo da Vinci was the author of what he (Kemp) dubbed “La Bella Principessa”. Thus, a collection of not-evidence was vested with quasi-evidential force on a circular, question-begging appeal to the claimed authority of a “sustained, collective sense that the portrait ‘belongs’ to Leonardo and contributes something new to the Leonardo we currently know.”

Although some scholars (chiefly Italian) were persuaded by the claims, for the consensual majority who did not see Leonardo’s hand in the drawing, Kemp’s methodological ju-ju gained no traction. His claims were advanced in a portmanteau book of collective advocacy, La Bella Principessa – The Story of the New Masterpiece by Leonardo da Vinci, which he co-wrote with Pascal Cotte of Lumiere Technology (the firm hired by the drawing’s owner, Peter Silverman, to conduct technical research) and which carried highly supportive contributions by Peter Paul Biro, Eva Schwan, Claudio Strinati and Nicholas Turner; London, 2010 (– see pp. 187-88).

THE THREE STITCH HOLES

During Pascal Cotte’s technical analysis of the drawing it was noticed that three holes are present on the left-hand edge. Cotte took these to “prove that it originally came from a book or a manuscript” (- Kemp/Cotte 2010, p. 113). Working with Mr Cotte, Prof. Kemp proposed that the hypothetical book might well have been a collection of celebratory poems of Bianca Sforza who had died in childhood and that “La Bella Principessa” had been made as an illustration to such a book.

Above, Fig. 2: “La Bella Principessa” with Pascal Cotte’s indicated locations of the three supposed stitch holes.

Kemp’s elaborate hypothetical advocacy constituted a daisy-chain of improbabilities. This is a drawing made in the manner of a distinctive (and invariably painted) profile portrait type that is nowhere encountered in recorded Leonardos – and, indeed, this is the very type which Leonardo famously subverted with his own revolutionary plastically dynamic figural innovations. Within the rigorous constraints of the strict profile type, this drawing’s supposedly high-born subject is bereft of the customary/requisite opulence in clothing and jewellery. The eccentric iconography was made on an atypical support – vellum. It was drawn, Kemp holds, either directly from the subject in celebration of her wedding, or, as a commemorative portrayal after her death and thus made either in recollection or from some other depiction. No explanation was offered for how this single image might have resulted from two radically different circumstances of execution.

THE CLAIMED CORRESPONDENCE BETWEEN THE “LA BELLA PRINCIPESSA” DRAWING AND THE WARSAW SFORZIAD

On a suggestion from Professor David Wright, Kemp proposed that this from-life or post-death portrait had been made to be incorporated within a large, heavy book of the mid-1490s that is now housed in Poland, the so-called Warsaw Sforziad. In the wake of a great deal of (Kemp and Silverman-activated) archival research which found no mention of any work resembling “La Bella Principessa”, it can be seen that without this claimed Warsaw connection, the drawing would remain what it was on its 1998 debut: a stylistically untypical and unprecedented work without any history – the inclusion of which within Leonardo’s oeuvre would, in Prof. Kemp’s own advocacy, “contribute something new to the Leonardo we currently know” and “reveal a previously unknown dimension to the way in which he fulfilled his duties at the court of Duke Ludovico Sforza”. (Kemp/Cotte, 2010, p. 188.) Without history, that is to say, other than the time it is now said to have been in the possession of the restorer/painter Giannino Marchig, the late husband of the anonymous vendor in 1998.

It has been claimed many times that a ‘match’ exists between the drawing’s holes and the book’s stitches but, aside from the small format photo-diagram at Fig. 3, this has never been demonstrated or independently corroborated. Similarly, it has been said that carbon dating tests established that the vellum sheet on which the drawing was made is of an age securely consistent with a drawing being made by Leonardo in the mid-1490s. This claim is seriously misleading, as is shown below.

THE TESTIMONY OF HOLES

Before Prof. Wright’s suggestion, in 2010 Pascal Cotte regarded the three holes on the drawing’s left-hand edge as evidence that might identify incorporation within a specific book:

“It would be interesting to use the evidence of the nature and placement of these needle holes to look for other surviving quires from the same codex, which, with other physical clues, might shed further light on the provenance and original commission.”

(Kemp/Cotte, 2010, page 113.)

Cotte’s hope was reasonable but such testimony can cut both ways. Establishing a relationship between the drawing and a particular book requires an exact correspondence between the drawing’s holes and a book’s stitches. Two separate claims were made of a discovered fit with the Warsaw Sforziad, first by the drawing’s owner, Peter Silverman, and then jointly by Martin Kemp and Pascal Cotte. Both occasions were filmed by National Geographic but only the second was broadcast. In it, Kemp expressed himself as being 80% confident. The presently claimed location of the drawing is at the front of the Sforziad. Clearly, the credibility of what is now a 200 million euro-insured drawing that is stored in the Geneva Free Port depends greatly on confidence being maintained in this claimed connection.

Above, Fig. 3: A facsimile of “La Bella Principessa” inserted into the Warsaw Sforziad with five arrows marking the
book’s stitches and three circles in which matches are claimed, but are not evident, between the drawing’s holes and
the book’s outer and central stitches. (The stitch marked by the right-hand arrow is shown in close-up below at Fig. 5.)

As previously shown, our colleague in ArtWatch, Dr Kasia Pisarek, has catalogued very many discrepancies between the drawing and the book, the most problematic being that the former has only three stitch holes, when the latter was bound with five stitches. To cope with this material/arithmetical incompatibility, Kemp and Cotte conjured two hypotheses.

The first was that the book had originally been bound with only three stitches and that at some undated point the drawing had been removed during a rebinding in which two extra stitches were added to the book. That (unsupported) contention was technically implausible: the book is too large and heavy to be supported by just three stitches – and
both of its sister volumes in London and Paris were bound with five stitches.

The second, and now preferred, hypothesis is that the book was indeed originally bound with five stitches and that, as
a part of this book, the drawing originally possessed the requisite five stitch holes, two of which had subsequently been cut off from the sheet. We demonstrated the impossibility of that claim in an earlier post. (To recap briefly: as Cotte had acknowledged in 2010, stitch holes are always made in a straight line along the crease in a group of folded sheets. Given that a central and two outer stitch holes are all present on the “La Bella Principessa” sheet, any original intermediary stitch holes would necessarily be found in alignment with the present three holes on the sheet as it is today.)

In addition to the absence of the two requisite stitch holes, the sheet itself is a mismatch in terms of colour, texture and size with the sheets in the book. Kasia Pisarek now adds a further mismatch:

“The follicles in the ‘La Bella Principessa’ vellum are tightly spaced, while those in the Sforziad vellum are widely spaced. This can be seen on the Polona website, where you can zoom in until you can see the follicles as dots. I remember seeing some pages where the dots were more apparent and they were definitely widely spaced.”

WHAT LIES BENEATH?

Yet another unaddressed difficulty concerns the back of the drawing. One of the earliest proponents of a Leonardo ascription, Dr Cristina Geddo, has described the presence on the reverse of the drawing of random lettering and an image of a dragon. Kemp and Cotte seem not to have offered an explanation for this content (which, presumably, was revealed by Cotte’s penetrative photography) even though they now claim that the back of the drawing would have faced the book’s beautiful and elaborately painted, symbolically-charged frontispiece. What conceivable iconographic function might such a melange have served in that strategic context of so important and precious a book? Dr Geddo has called for the vellum drawing to be removed from its (most unusual) oak panel support but the owner has declined to do so on grounds of safety. Some of the lettering is visible in an X-ray photograph published in the 2010 and 2012 English and Italian editions of the Kemp/Cotte joint book.

FIVE HOLES GOOD, THREE HOLES BAD

As we reported previously, with regard to the Three Holes v. Five Stitches conundrum, the problems for supporters of “La Bella Principessa” have now become insurmountable: Pisarek established on her second examination of the Warsaw Sforziad in the Polish National Library that while the drawing bears only three holes, the book itself was not only bound with five stitches but that each of those stitches passed through two holes that were two or three millimetres apart (see Figs. 6, 7 and 8 below). At a stroke, the previously claimed ‘fit’ between the drawing and the book is demolished: the drawing possesses only three single stitch holes when it should have five pairs of holes making ten in total. Even if it were to be conceded that two inner stitches might once have been present, today’s three single holes should be three pairs of holes, making six holes in total, not three.

AN OWNER’S RESPONSE

When we sent our previous “La Bella Principessa” post with the newly disqualifying physical/technical evidence to the drawing’s owner, Peter Silverman, (13 June), he dismissed the bearers of the information by alleging lack of expertise: “I leave the attribution question to serious and highly qualified experts!!!” In support of his professional slur, Silverman copied-in two messages to us. The first had been sent to him, at his request, by a costume expert, Elisabetta Gnigera. The second Silverman had sent to Jean Penicaut, the CEO of Lumiere Technology. It was evidently written in haste and heat:

“Dear Jean
I am sorry but we, as owners of the BP, are not to be told how and with whom to talk! I understand your frustration in dealing with Artwatch and Franck but i feel that Pisareks statement must not and cannot be left unchallenged! I therefore request you to rebut each and every point in this latest statement-most importantly of all i would like to see the INDISPUTABLE proof of the binding holes, in a first and separate email to me! Unfortunaley Martin has made statements which can be perverted by anyone in bad faith-equivocal statements quoted in the first part of the enclosed article!!
“I would like Elisabetta to comment on the costume questions.
And i would like YOU to extensively quote from the lab results of La Veneria*, which is very helpful to our cause! [*This is a reference the conservation laboratory “La Venaria Reale” which has conducted analysis of the drawing.]
“We cannot afford to lose the high ground’ in this battle-no matter the bad faith of our ennemy.
“To avoid your corresponding with them please send the rebuttal to me. I INSIST THAT THIS IS AN ABSOLUTE NECESSITY!!
Best, peter

http://artwatch.org.uk/problems-with-la-bella-principessa-part-iii-dr-pisarek-responds-to-prof-kemp/

“PS-the good news is that there is a very serious party interested in acquiring a share in the BP(highly confidential) and July 1 will be a decisive day!!!”

It would seem after more than a month that Lumiere Technology has not provided the owner with indisputable evidence of a connection between the drawing and the Warsaw book that would counter Pisarek’s account. On 14 June we replied to Mr Silverman:

“Speaking of clarification and your requests, I note the various requests from the ‘owners of the BP’ to your associates
to read our current post, and your talk of a prospective part-sale of the BP. Can I take it that the potential buyer of whom you speak has been similarly advised?

“Also, perhaps you might say how you will respond if Jean Penicaut advises you, as we would predict, that he can find
no ‘INDISPUTABLE proof of the binding holes’ that might enable you – or he on your behalf – ‘to rebut each and every point in this latest statement [in the then current AWUK post]’”?

Concerning the La Venaria Reale laboratory reports, we asked Mr Silverman on 15 June:

“On your technical ‘proofs-of-authenticity’ and our possible viewing of your Swiss-vaulted, soon-to-be part-sold drawing, might we not deal with both by: a) your sending to us all reports and data that have been made available to you; and, b) your bringing the drawing to either Paris or London so that we might arrange a group viewing by sceptics and rejecters?”

MISINTERPRETED REPORTS

After more than a month we have received no technical reports on “La Bella Principessa”. Lumiere Technology’s
apparent silence on the conflicting number of stitch holes seems remiss. In our experience it is valuable to see the reports themselves because evidence can sometimes be interpreted and presented in ways that might mislead. For example, it has been claimed (technically-speaking correctly) that carbon dating has established a 95.4% probability
that “La Bella Principessa” had been made at some point between 1440 and 1650. On that particular technical examination and very wide range of possible ages, Pascal Cotte (2010, p. 110) has claimed a number of things in a single sentence:

“This dating confirms that the portrait could well have been made in Leonardo’s lifetime, supporting Martin Kemp’s proposed date in the mid-1490s and virtually eliminating the possibility that it is a 19th century pastiche.”

This was all quite misleading. A confirmed “could well have” remains a “could have” and does not become a confirming “was”. A “virtually eliminated possibility” remains a possibility. Taken as a whole and properly appraised, the data itself cannot reasonably be said to support Kemp’s claimed date and authorship – in fact, it does the opposite.

Cotte’s claims rest on what is only a loose and very wide overall estimation of probability. While it is true to say there is a 95.4% chance that the sheet appeared at some point between 1440 and 1650, there is not a 95.4% probability that it appeared before the mid-1490s when the Sforziad was made. Even on that loose, overall range of possibilities, it would be more accurate to say that because we know (today) that the Warsaw book was made in the 1490s (and had known in 2010 that the proposed subject of “La Bella Principessa”, Bianca Sforza, had died in 1496), it is three times more likely that the “La Bella Principessa” sheet post-dated rather than predated the book. What has not been acknowledged is that within the overall figure, the probabilities had been greatly more precisely quantified.

It was said in the report, for example, that there was a 68.2% probability that the sheet was made between 1470 and 1650 and that, within this period (see Fig. 4 below), there was only a 27.2% probability that the drawing was made between 1470 and 1530 – and this was compared against the appreciably greater probability (41.0%) that the sheet was made some time between 1550 and 1650 – which would place the sheet altogether much later than Leonardo who died in 1519. Properly read, with a proposed date for the drawing set in the mid-1490s, the data shows that there was only a 13.6% probability that the “La Bella Principessa” sheet existed when the book was made. When the general 95.4% probability of an origin anywhere between 1470 and 1650 and the 13.6% probability of an origin between 1470 and 1495 are expressed as racing odds, it is seven times more likely that the sheet was made after the book than before it. And the odds of seven to one against pertain to the vellum sheet itself, not to the possible dates of execution for the drawing. Even if this sheet had once been present in that book, such a dating would indicate only the age of the material, not the date of the drawing’s execution. On this last, we should recall that Eric Hebborn advised in his The Art Forger’s Handbook that a prime source of old materials for forged drawings is obtained from blank end papers in books. Thieves cut valuable illuminated pages from books. Forgers crave blank pages but will make use of a blank side by gluing its reverse firmly to some impenetrable material.

Above, Fig. 4: The carbon dating report on the “La Bella Principessa” sheet (as published by Kemp/Cotte, 2010, p. 110).

FOR THE RECORD

Where Mr Silverman declines to make reports available to us, and Pascal Cotte fails to demonstrate a fit between the drawing’s three stitch holes and the book’s ten stitch holes, we now present further visual proofs and documentary confirmation of the previously claimed mismatch to demonstrate precisely why “La Bella Principessa” could never have been part of the Warsaw Sforziad.

INSTITUTIONAL CORROBORATION

On 23 June 2016 Barbara Dzierzanowska, the Head of Department of Old Prints BN at the National Library of Poland, wrote to Kasia Pisarek:

“Dear Madam,

I would like to inform you that yesterday we entered the Treasury and re-examined the Sforziad, which has confirmed that the binding stitches are double and there are 10 holes.

Yours sincerely,

Barbara Dzierzanowska”

PHOTOGRAPHICALLY-RECORDED AND ELECTRONICALLY TRANSMITTED PROOF OF THE DOUBLE STITCHING OF THE WARSAW SFORZIAD

That the stitching of the Sforziad was made through double holes can be seen by eye on the book itself, as shown below at Fig. 5.

Above, Fig. 5: A stitch made through two holes, as seen on the numbered page 1 of the Warsaw Sforziad. In this photograph, the top stitch and the two flanking holes are shown but some of the other holes can also be seen on stitches below it. This stitch/holes configuration would have been evident when (as described above) a full-size facsimile of “La Bella Principessa” was inserted into the Sforziad at precisely this point. This evidence is also available online: our image was taken from the detailed record of the entire book that is carried on this site: Polona – La Sforziada.

ESTABLISHING THE TRUE DIMENSIONS

When Kasia Pisarek inspected the book for the second time, she asked that the dimensions of the pages and the relative positions of the stitch holes be marked along the edge of a piece of paper. This was done by the library’s books’ conservator in her presence and that of the chief librarian. Intervals between the stitch holes were marked in pencil along the two sides of the strip of paper and these are shown here at Figs. 6 and 7. When we marked off those measurements onto a separate sheet of paper, to prepare the diagram at Fig. 8, and then measured them on our sheet with a ruler, they were all exactly as given by Pisarek. We can be sure, therefore, that the dimensions and ratios between the stitch holes as shown below at Fig. 8 have been accurately established and physically transported to ArtWatch UK – and at practically zero-cost by means of sharp pencils and two pieces of paper.

Above, Figs. 6 (top) and 7: The strip of paper on which the book’s page size and stitch holes were recorded, as described above.

The conservator explained to Pisarek that the present positions of the stitch holes were those of the original construction of the book and that, therefore, there was no possibility that the book had once been bound with only three stitches. She made diagrams on the strip showing (at Fig. 7) different ways of executing stitching with double holes.

THE DIMENSIONS OF THE INTERVALS BETWEEN THE STITCHES IN THE BOOK – A NOTE FROM KASIA PISAREK:

1) According to Kemp and Cotte, the dimensions of the vellum pages of the Sforziad vary from 33.0 to 33.4 cm in height, while the drawing is 33 cm high.

2) I have carefully checked the dimensions with the Librarian in March 2016. All the pages are at least 33.4 cm high and more, up to 33.7 cm. The size of 33 cm would be far too small for the book.

3) The 5 holes in the book are in fact all double holes. Each of the 5 holes is two small holes, between which a string passes. The distance between the two small holes is about 3 mm. The double holes were never mentioned by Kemp or Cotte.

4) According to the conservator who was present at the time of my last visit, this is the binding that follows the original binding as there is no damage of any kind. So in total there were as many as 10 small holes, not 3 single ones as in the drawing.

5) I measured the distances between the 3 holes that Kemp and Cotte measured in La Bella Principessa. The measurements were taken from the middle of the double holes.

6) The distance between the bottom hole and the middle hole is 11.35 cm in the Sforziad, while in the drawing it is 11.06 cm.

7) The distance between the middle hole and the top hole is 11.7 cm in the Sforziad, while in the drawing it is 11.44 cm.

THE MISMATCHED HOLES AND STITCHES

Above Fig. 8: We took the dimensions of the Sforziad’s page and stitch holes from the strip of paper marked by the Polish National Library’s books’ conservator (as shown at Figs. 6 and 7) and drew them in black, as above, and marked “WS”. We then drew in red the “La Bella Principessa” sheet (here marked “LBP”) and its stitch holes as given above by Pisarek.
As can be seen above, it is impossible to align the drawing’s single stitch holes with their claimed counterparts in the book. If the drawing’s centre hole is aligned with the centre of the two central holes in the book (as shown on the left here), its other two holes fall short of their claimed counterparts.
If the LBP drawing’s upper hole is aligned with the centre of book’s two upper holes, its central and lower holes fall progressively further short of their claimed counterparts on the book.
In short, there is no fit or match between the book and the drawing – and which drawing in all probability post-dated the book, for reasons indicated above.

Those who would continue to give this drawing to Leonardo must now find some other means of filling a five centuries absence of provenance and of squaring intractable technical circles. We will examine next the supposed left-handed execution of “La Bella Principessa”.

Problems with “La Bella Principessa”~ Part I: The Look

The world famous drawing that was dubbed “La Bella Principessa” by Professor Martin Kemp is insured for $150 million and lives in a “secure vault in Zurich”. It is not a portrait of Bianca Sforza by Leonardo da Vinci, as has been claimed, but a twentieth century forged or pastiche Leonardo.

WHITHER “LA BELLA PRINCIPESSA”

In 1998 the now so-called “La Bella Principessa” appeared from nowhere at Christie’s, New York. A hybrid work made in mixed media that were never employed by Leonardo (three chalks, ink, “liquid colour”), on a support that was never used by Leonardo (vellum), and portraying a woman in a manner that is nowhere encountered in Leonardo, it was presented as “German School, early 19th century” and “the property of a lady”. It went for $22,850 to a New York dealer who sold it nine years later on a requested discount of 10 per cent for $19,000 to an art collector, Peter Silverman, who said he was buying on behalf of another (unidentified) collector whom he later described as one of “the richest men in Europe”. Thus, at that date, it was not known who owned the drawing or by whom it had been consigned to Christie’s and it remained entirely without provenance. In its nine years long life, no one – not even its new owner(s) – had taken it to be by Leonardo.

In a 2012 book (Lost Princess ~ One man’s quest to authenticate an unknown portrait by Leonardo da Vinci), Silverman claimed a successful upgrading to Leonardo and described how he had gained the support of distinguished scholars including Professor Martin Kemp who had formulated an elaborate hypothetical history in which the drawing was said to be a Leonardo portrait made either from a living subject in celebration of her wedding or in commemoration after her death in 1496.

Nonetheless, the drawing failed to gain a consensus of scholarly support and is rejected in centres like New York, London and Vienna. Carmen Bambach, the Metropolitan Museum’s Renaissance drawings authority dismissed “La Bella” on the grounds that “It does not look like a Leonardo”. Thomas Hoving, a former Metropolitan Museum director, held it to look “too sweet” to be Leonardo. ARTnews reported that the Albertina Museum’s director, Klaus Albrecht Schröder, had noted “No one is convinced it is a Leonardo”. In the Burlington Magazine Professor David Ekserdjian suspected it to be “counterfeit”.

THE LOOK OF “LA BELLA” AND THE COMPANY SHE BEST KEEPS

In matters of attribution the most important consideration is the look of a work. Many things can be appraised simultaneously but, conceptually, the “look” of a work might be broken down into two aspects: an initial at-a-glance response to a work’s effects and appraisal of its internal values and relationships; and, a comparison of the effects, relationships and values with those of bona fide productions of the attributed artist, or with those of the artist’s students, associates or followers. It can also be useful to compare the looks of works with those of copyists and known forgers. It might fairly be said that in connoisseurship, as in the evaluation of restorations, visual comparisons are of the essence. (In ArtWatch we take pride in the extent to which we seek out all possible comparative visual material and regret that some institutions still hinder our efforts in this regard.)

Above, Fig. 1. If we put aside questions of attribution and simply look at the group above, we find works of remarkably similar figural motifs and formats that clearly relate to and derive from a most distinctive type of 15th century Italian profile female portrait. These similar-looking works are similarly sized, being, respectively from left to right:

A Young Woman, 14 and 1/4 x 10 inches;
“La Bella Principessa”, 13 x 9 and 3/4 inches; and,
A Young Woman, 18 x 12 1/2 inches (here shown mirrored).

All show young women depicted in the strict early Renaissance profile convention made in emulation of antique relief portraits on coins and medals. Although very widely encountered (see Fig. 4), Leonardo side-stepped the type in order to intensify plastic and expressive values with sculpturally-purposive shading and axial shifts in the bodies and gazes of his portraits (see Fig. 6). The portrayals above are strikingly similar in their head/torso relationships; in their absences of background; in their highly elaborated coiffures which offset ‘sartorially’ skimped and unconvincing simplifications of costume; in their sparse or wholly absent depictions of jewellery; and, even, in their almost identically cropped motifs. Collectively they might be taken as a suite of variations on a simple theme. We take all three to be twentieth century Italian artefacts. At least two of them are linked to Bernard Berenson and the two on which reports have been published have unusual and problematic supports.

As mentioned below, the Detroit picture is painted on top of photographic paper. It is suspected that it might have been a photograph of the Frick sculpture to which the painting was initially related. The “La Bella Principessa” is drawn, exceptionally for Leonardo, on a sheet of vellum which appears to have been removed from a book and it is, most unusually, glued to an oak panel. The panel itself is a curiosity: although a number of “butterfly keys” have been inserted into its back, as if to restrain splitting, there is no evidence of splits in the panel and, if there were, the present four such keys in such a small panel might be considered restoration “over-kill”. If the panel had split while the vellum was glued to it, the drawing would have split with the panel. The fact that the vellum has been “copiously glued” to a (possibly pre-restored) oak panel makes it impossible to examine the back of the drawing which is said by one of its proponents, (Cristina Geddo, an expert in Leonardo’s students and Milanese “Leonardesques”) to bear “superimposed numbers…a written inscription…[and a] little winged dragon – at least that is what it seems.” For Geddo, this unexamined content is reassuring: “This feature, too, counts in favour of an attribution to Leonardo, who, even though he never to our knowledge used a parchment support in his work, was in the habit of re-using the paper on which he drew.”

(In reading the compendious literature on this proposed attribution, we have sometimes wondered what might be allowed by its supporters to count as evidence against the attribution.)

CONSIDER THE HISTORIES

The portrait on the left, A Young Woman, was bought in 1936 by the Detroit Institute of Arts as by Leonardo da Vinci or Andrea del Verrocchio. The institute’s director, W. D. Valentiner, made this attribution on the strength of clear correspondences with the curls in the hair of Leonardo’s painting Ginevra de’ Benci (see Fig. 6) in the National Gallery of Art, Washington, and with those found in the above-mentioned marble sculpture in the Frick Museum, A Young Woman, given to Andrea del Verrocchio. (Valentiner had made a study of Leonardo’s work in Verrocchio’s workshop.) In 1991 Piero Adorno, specifically identified the Detroit picture as Verrocchio’s lost portrait of Lucrezia Donati. Notwithstanding seeming correspondences with secure works, this picture is now relegated to “An Imitator of Verrochio” – and this is an extremely charitable formulation. In Virtue and Beauty, 2001, David Alan Brown described it as “a probable forgery by its anachronistic materials and unorthodox construction”. “Probable” [!] because: “after a recent technical examination, the picture turns out to have been painted on photographic paper applied to a wood panel that was repaired before it was readied for painting. And at least one of the pigments employed – zinc white – is modern…” Valentiner judged one of two Leonardo studio works of the Madonna with a Yarnwinder to be “more beautiful than the Mona Lisa”.

The portrait on the right, A Young Woman, was attributed to Piero Pollaiuolo by Berenson in 1945. While this figure is perhaps the most attractive of the above three, with its nicely constructed counterbalancing of the thrusts in the neck/head and torso, and its credibly proportioned arm, the work itself has, so far as we can ascertain, sunk without trace. In truth, this female profile portrait type has been assailed by forgeries. Alison Wright notes in her 2005 book The Pollaiuolo Brothers, that “Complications for the historian lie both in the fact that the subjects of most female portraits are no longer identifiable and that, because of their exceptional decorative and historical appeal, such portraits were highly sought after by later nineteenth- and early twentieth-century collectors, encouraging a market for copies, fakes and over-ambitious attributions.”

The portrait in the centre (“La Bella Principessa”) has been precisely attributed by Kemp to Leonardo as a book illustration portrait of Bianca Sforza of 1495-96.

DISTINGUISHING BETWEEN THE LOOKS OF THEN OF NOW

Above, Fig. 2. In My dear BB (an incalculably valuable new resource edited and annotated by Robert Cumming), we learn that in November 1930 Kenneth Clark’s wife, Jane, wrote to Berenson: “K has seen Lord Lee’s two new pictures…The Botticelli Madonna and Child you probably know too. K thinks the latter may be genuine about 1485 or rather part of it may be, but it is not a pretty picture…” A footnote discloses that Lee had bought The Madonna of the Veil, a tempera painting on panel in 1930 from an Italian dealer for a then huge sum of $25,000 (Fig. 3). It was widely accepted by scholars as autograph Botticelli and published by the Medici Society as a “superb composition of the greatest of all Florentine painters”. Clark, doubting the attribution on sight, objected that it had “something of the silent cinema star about it” – and he likened the Madonna to Jean Harlow (Fig. 3). Lee donated the picture to the Courtauld Institute Gallery in 1947. In June 2010 Juliet Chippendale (a National Gallery curatorial intern working in association with the Courtauld Institute MA course) disclosed that scientific examination had identified pigments not known before the 18th and 19th centuries and worm holes that had been produced by a drill. It is now designated a work of the forger Umberto Giunti (1886-1970), who taught at the Institute of Fine Art in Siena and forged fresco fragments.

ART HISTORICAL SILENCES

Four months later Clark wrote to Berenson: “Just in case Lee has sent you a photograph of his new Botticelli may I ask you to forget anything Jane may have reported me as having said of it. It is one of those pictures about which it is best to be silent: in fact I am coming to believe it is best for me to be silent about every picture. Did I tell you that my Leonardo book was a mare’s nest. The man had sent photographs of two drawings from the middle of the Codice Atlantico. They must have been early copies done with some fraudulent motive – perhaps the book really did belong to Leonardo – he certainly had read it – & some pupil thought to enhance its value.”

Above Fig. 3. The young Kenneth Clark (then twenty-seven years old) displayed an admirable “eye” by spotting a fraud on sight some eighty years ahead of the pack. Is it better for a connoisseur to see but not speak than it is not to see at all? Undoubtedly, it is. Would Clark have enjoyed his meteoric rise had he humiliated the mighty and exposed the big-time fraudsters of his day? (That question might be taken as self-answering.) If Clark bided his time on Berenson, eventually he delivered an unforgiving former-insider’s repudiation in 1977 by chronicling how Berenson had “sat on a pinnacle of corruption [and] for almost forty years after 1900… [done] practically nothing except authenticate pictures”

PRETTY – AND NOT SO PRETTY – WOMEN

Above, Fig. 4. In the middle and bottom rows we see three bona fide works of the female profile type – respectively:

Portrait of Bianca Maria Sforza, c. 1493, by Ambrogio de Predis, The National Gallery of Art, Washington;
Domenico Ghirlandaio’s 1488-1490 Giovanna degli Albizzi Tornabuoni, Museo Thyssen-Bornemisza, Madrid; and,
a portrait of Beatrice d’Este tentatively attributed by Kemp to Ambrogio da Predis.

The differences between this trio and the works in the top row are pronounced and eloquent. The secure works are highly individuated and immensely richer in their effects. Collectively, they do not constitute an inadvertent suite. Individually, they are greatly more various compositionally. Collectively, they are markedly richer in jewellery and ostentatiously sumptuous costumes. The distinctive physiognomies of their subjects derive from living persons, not from other art or photographs of other art. Flattery and loving attention are channelled more into the costume and bling than into the facial features. In every respect the opposite is the case in the top row where prettiness has been held at a premium with an eye on the modern photographically-informed market.

LEONARDO BREAKS THE MOULD

Above, Fig. 5: As mentioned, “La Bella Principessa” and her two companions are of a piece, and of a type never followed by Leonardo whose female portraits (see below) pioneered an unprecedentedly complex and sophisticated evocation of real, sculpturally palpable women in tangible spaces or landscapes. To include the figurally impoverished and stylistically anachronistic “La Bella Principessa” in Leonardo’s oeuvre would disjunct his revolutionary arc of insights and innovations in portraiture. Such inescapably disruptive consequences have been ceded tacitly by Kemp, “La Bella Principessa’s” principle defender – some say advocate. In “La Bella Principessa ~ The Story of the New Masterpiece by Leonardo da Vinci” (Kemp’s 2010 book jointly written with Pascal Cotte of Lumiere Technology and including chapters by the drawings scholar Nicholas Turner and the recently discredited fingerpints expert Peter Paul Biro), Kemp converts an intractable problem into an asset by begging the essential question. That is, he underwrites “La Bella’s” credibility on an assertion that “Any important new work, to establish itself, must significantly affect the totality of Leonardo’s surviving legacy over the longer term.” Without question, the de-stabilising inclusion of “La Bella Principessa” would produce knock-on effects, but arguing backwards from that predictable disturbance to some endorsement of its source is patently unsound methodologically – the inclusion of any atypical work, whether bona fide or forged, into an oeuvre would affect its “legacy”.

LEONARDO’S ACCOMPLISHMENTS

Above, top, Fig. 6: Left, Andrea del Verrocchio’s Lady with a Bunch of Flowers of c. 1475; and (right) Leonardo’s (hypothetically extended) Ginevra de’ Benci of c. 1474-1478.

Above, Fig. 7: Left, Leonardo’s The Lady With an Ermine of about 1489-90; centre, Leonardo’s La Belle Ferronnière of about 1495-96; right, Leonardo’s Mona Lisa (La Giaconda) of about 1503-06 onwards.

In the group above we see extraordinary development in Leonardo’s portraits of women over the last quarter of the fifteenth century as he strove to incorporate the entirety of sculptural, plastic, figural knowledge, and to surpass it by making it dance to an artistically purposive tune liberated from the happenstance, arbitrary lights of nature on which sculpture then necessarily depended. Some have attributed the Bargello sculpture, the Lady with a Bunch of Flowers, to Leonardo on the grounds that its subject was Ginevra de’ Benci, the subject of Leonardo’s painting. Others have seen Leonardo’s authorship of it in the beauty of the hands. In Leonardo da Vinci and the Art of Sculpture, 2010, Gary M. Radke holds that the two works show differences that emerged in the mid-1470s between the two artists. Against this, it has been suggested that the painting might originally have borne a closer relationship to the sculpture with a possible inclusion of hands in a fuller length treatment. A study of hands by Leonardo was incorporated in a hypothetical and digitally realised extension of the painting by David Alan Brown (Virtue and Beauty, 2001, p. 143). Frank Zollner sees the painting as marking the point (1478-1480) at which Leonardo broke away from “the profile view traditionally employed in Florence for portraits of women” in favour of the three-quarters view in order to impart “a pyschological dimension to his sitter – something that would become the hallmark of Renaissance portraiture”. Which is all to say that Leonardo had broken away from the profile convention some sixteen to eighteen years before, on Kemp’s hypothesis, he made a solitary and exceptional “return” to it.

Speaking of the reconstruction of Leonardo’s Ginevra de’ Benci painting, Brown writes:

“Ginevra’s portrait, the lower part of which was cut down after suffering some damage, may have included hands. A drawing of hands by Leonardo at Windsor Castle, assuming it is a preliminary study, aids in reconstructing the original format of the picture. As reconstructed, Leonardo’s portrait may be seen to have broken with the long-standing Florentine convention of portraying women in bust-length profile. In seeking an alternative to the static profile, Leonardo, like Botticelli, seems to have turned to Verrocchio’s Lady with a Bunch of Flowers in the Bargello, Florence. Because of the sitter’s beautiful hands which mark an advance over the earlier head-and-shoulders type of sculpted bust, the marble has even been attributed to Leonardo. But the highly innovative conception of the half-length portrait bust is surely Verrocchio’s achievement. What young Leonardo did was to was to translate this sculptural protype into a pictorial context, placing his sitter into a watery landscape shrouded in a bluish haze…”

A CASE CONSPICUOUSLY NOT MADE

For the owner and the art historical proponents of “La Bella Principessa”, the very chronology of Leonardo’s female portraits constitutes an obstacle. Given Leonardo’s famous eschewal of strict profile depictions of women, the onus is on those who would include “La Bella Principessa” (- albeit as a solitary and exceptional stylistic regression that was undertaken without ever attracting attention or comment) to make a double case.
First, they must show how and where “La Bella Principessa” might plausibly have fitted within the trajectory of Leonardo’s accepted works. Second, they must demonstrate by comparative visual means that “La Bella Principessa” is the artistic equal of the chronologically adjacent works within the oeuvre. Kemp has proposed the precise date of 1495-96 for the execution of “La Bella Principessa” but, conspicuously, has not presented direct, side-by-side visual comparisons with Leonardo’s paintings. Instead of comparing “La Bella Principessa” of 1495-6 directly with Leonardo’s La Belle Ferronnière of about 1495-6, Kemp writes:

“If the subject of Leonardo’s drawing is Bianca, it is likely to date from 1495-6. In style, it seems at first sight to belong with his earlier works rather than to the period of the Last Supper. However, Leonardo was a master of adapting style to subject. Just as his handwriting took on an earlier cast when he needed to adopt a formal script, so his drawing style could have reverted to a meticulous formality, appropriate for a precious set-piece portrait on vellum of a Sforza princess.”

“If”? “Could have”? “At first sight”? The pro-attribution literature is bedecked with daisy-chains of such tendentious and weasel words and terms. With which earlier works is “La Bella Pricipessa” deemed to be artistically comparable or compatible? With the Ginevra de’ Benci of c. 1474-1478? With The Lady With an Ermine of about 1489-90? Never mind the red herrings of handwriting and the giant, near-obliterated historical figures of the Last Supper, what of the relationship with Leonardo’s (supposedly) absolutely contemporaneous La Belle Ferronnière of 1495-96? (On this last we volunteer a pair of comparisons below.)

Above, Top, Fig. 8: Leonardo’s La Belle Ferronnière, left, and the “La Bella Principessa”.
Above, Fig. 9: Details of Leonardo’s La Belle Ferronnière, left, and the “La Bella Principessa”.

Kemp insists: “The Lady in profile [“La Bella Principessa”] is an important addition to Leonardo’s canon. It shows him utilizing a medium that has not previously been observed in his oeuvre…It testifies to his spectacular explosion and development of novel media, tackling each commission as a fresh technical challenge. It enriches our insights into his role at the Milanese court, most notably in his depiction of the Sforza ‘ladies’ – whether family members or mistresses. Above all, it is a work of extraordinary beauty.”

Even if we were to assume that for some reason Leonardo had opted to “revert” in 1496 to a type he had never employed, what might explain a pronounced indifference in “La Bella Principessa” to the detailed depiction of the “stuffs” of costume with which the artist was simultaneously engaged in La Belle Ferronnière? Given that Leonardo clearly appreciated and celebrated the fact that courtly costume required sleeves to be made as independent garments held decorously in place by ribbon bows so as to permit undergarments to peep through; and, given that Leonardo lovingly depicted not only the varying thicknesses of the costume materials but every individual twist in the threads of the elaborately embroidered band in La Belle Ferronnière, how could he possibly – when working for same ducal master, at the same time – have been so negligent and indifferent in the execution of “La Bella Principessa’s” costume? Kemp acknowledges and offers excuse for the distinct poverty of the costume: “It may be that the restraint of her costume and lack of celebratory jewellery indicates that the portrait was destined for a memorial rather than a matrimonial volume.” In so-saying, he jumps out of one frying pan into another.

If “La Bella Principessa” was made after Bianca Sforza’s death, from whence did the likeness derive? One reason why Kemp settled on Bianca as the preferred candidate subject for “La Bella Principessa” was that while (disqualifying) likenesses of the other Sforza princesses existed, none survives for her – she is an image-free figure. Kemp offers no indication of a possible means for Leonardo’s (hypothesised) post-death conjuring of Bianca’s supposed likeness other than to claim that “Leonardo has evoked the sitter’s living presence with an uncanny sense of vitality.” This again begs the crucial question and fails to consider any alternative explanations for the image’s qualities. (We will be showing how the profile of “La Bella Principessa” could well have been a “portmanteau” composite image assembled from one particular work of Leonardo’s and from that of another, unrelated painter.)

The most strikingly “Leonardesque” feature on the costume of “La Bella Principessa” – the knot patterning around the (implausible) triangular slash in the outer garment – is a source of further concern and constitutes evidence of forgery. First, the motif on which much effort will have been expended, is brutally cropped along the bottom edge of the sheet, as if by a careless designer laying a photograph into a book. Why would any Renaissance artist, let alone Leonardo, design a complicated feature so as to “run it off the page”? Further, the illusion of form (created by lights and shades) in the patterning is feeble in the extreme for Leonardo – as when compared with his treament of relief seen in the above embroidered passage in La Belle Ferronnière, for example. Leonardo probably better understood than any artist in history the vital connection between a thing made and a thing depicted. He took bodies and organs apart to understand their construction and he sought to create mental models that would make the otherwise terrifyingly arbitrary and capricious forces of nature graspable if not checkable. Most seriously of all, as our colleague Kasia Pisarek has noted and reported, while the patterning present on “La Bella Principessa” matches none found in any work of Leonardo’s, it more closely matches that found in a carved marble bust by Gian Cristoforo Romano in the Louvre – see La Bella Principessa – Arguments against the Attribution to Leonardo”, Kasia Pisarek, artibus et historiae, no. 71, 2015.

In Parts II and III we examine: the provenance of “La Bella Principessa” and the work’s problematic emergence from within the circle of Bernard Berenson; the claim by the forger Shaun Greenhalgh to have produced “La Bella Principessa” in Britain in the 1970s; the spurious “left-handed-ness” of “La Bella Principessa” and the low quality of, and the means by which the drawing was made…


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
whose favour the prosperity of the institution depends.”

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.”

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.”
