Paul Biro
I should say with respect to the legal action of Paul Biro against the New Yorker that the work he undertook on the fingerprint on the portrait was conducted in an entirely straightforward and professional manner. He was shown the image of the print by Pascal Cotte and provided with comparative material from Leonardo’s paintings. I am now more cautious about whether we have adequate reference material and criteria for identifying a fingerprints by Leonardo to a good evidential level, but this is not to cast aspersions on the work he did for us. Whatever the rights and wrongs of the case, it is terrible to see someone’s career potentially going down in flames.
