Three academics from the Universities of Leipzig and Hamburg have written a five-volume study that casts doubt on the works held in Britain, which are among up to 40 per cent of the worlds Michelangelos that they believe should be dismissed as copies. The three academics argue that hundreds of drawings by Michelangelo cannot be circulating worldwide when contemporary accounts refer to the artist burning most of them. The three are also publishing a recently discovered contemporary document that explains how so few drawings by Michelangelo survived after his death. Its contents are so dramatic that one journal tried to suppress it, they claim.
