Flayed Muscle Man, "Anatomia del corpo humano", 1588. Juan Valverde de Amusco (de Hamusco) (1525-1558?) studied medicine in Padua and Rome under Realdo Columbo and Bartolomeo Eustachi. He published several works on anatomy, including De animi et corporis sanitate tuenda libellus (Paris, 1552). His most famous work was Historia de la composicion del cuerpo humano, published in 1556. All but four of its 42 engraved copperplate illustrations were taken directly from Andreas Vesalius's De humani corporis fabrica. Vesalius bitterly commented on Valverde's plagiarism, accusing him of having performed very few dissections himself. One of Valverde's most striking original plates is that of a muscle figure holding his own skin in one hand and a knife in the other, which has been likened to Saint Bartholomew in The Last Judgment (Michelangelo) of the Sistine Chapel.
