A few months ago, a terra-cotta bust of a woman passed through the London auction rooms, leaving a little puzzlement and worry in its wake. Once, in its glory days, as a work of Andrea del Verrocchio, it had graced the collection of J. Pierpont Morgan. That interesting scholar W.R. Valentiner, who earlier this century was lured from Berlin to the Metropolitan Museum in New York (his career forms a link between Bode’s Berlin and the Getty Museum in Malibu), compared the profile of the bust with a drawing by Leonardo in Windsor Castle. He thought that the master (Verrocchio) and his most famous pupil (Leonardo) might have used the same model. But other voices were raised to denounce the work as a fake. Or, if not a fake, as a portrait of a nineteenth-century sitter in Renaissance costume. This low opinion prevailed over Valentiner’s, and the bust was disgraced, deaccessioned, without chance of reprieve.
But that was not the end of the story, for the auction room catalog announced that the bust had recently been subjected to a thermoluminescence test, which proved that it had last been fired in or around the fifteenth century. Whatever it was, there was no reason to call it a fake. And if it was not a fake, perhaps Valentiner’s opinion might merit further consideration. For, when it came to Verrocchio scholarship, Valentiner was not nobody. In 1933 he was able to show that a candelabrum in the Schlossmuseum in Berlin was a documented work of Verrocchio. This is now one of the treasures of the Rijksmuseum.
There are not many known surviving works by Verrocchio. Andrew Butterfield’s new book lists thirty, of which four are uncertain and others seem more the work of the studio than of the master. That makes Verrocchio as rare as Vermeer, but with this exciting difference: Verrocchios—real ones—have turned up, both through inspired acts of reattribution and as objects previously unknown to scholarship. What is more, it is quite certain that there are others waiting to be found. In the 1980s, a terra-cotta modello for the figure of the executioner of John the Baptist turned up on the London antiques market. But other sketch models for the same relief scene were once known. If the heirs of Baron Adolphe Rothschild would just investigate their cupboards a little more carefully, they might yet find them.
One might think that with so many art historians crawling over every inch of its surface there would be nothing left to discover in Florence. But Butterfield, if he is right, has found a Verrocchio in the Bargello itself. And meanwhile a curator of that museum, Beatrice Paolozzi Strozzi, has made a particularly fascinating discovery. Taking a second look at an unprepossessing crucifix, which had already been logged as nothing in particular, she decided to have it cleaned. What emerged from beneath centuries of filth was the original polychromy of a Verrocchio Christ. This discovery …
