Lee Rosenbaum takes a look at claims by one scholar that the Metropolitan Museum’s Duccio (for which it paid $50 million last year) is a fake. “None of this proves that the painting is a fake from the 19th century, as Beck somewhat recklessly claims, or even that it’s not by Duccio. The Met’s conservation lab has done a technical examination of the painting that it says provides additional support for the attribution. It should release those findings in detail (including any attempts to date the painting scientifically), to help clarify these matters.”
