borrowed from his technique. Dürer was in Bologna in 1506, as was Michelangelo, and he may have met one or both of them. Reproductions About this time he began to make copies of Dürer's woodcut series, the Life of the Virgin. This was extremely common practice, although normally engravers copied other expensive engravings rather than the cheaper woodcuts. However Dürer's woodcuts had raised the standard of the medium considerably, and since Marcantonio continued to copy a large number of both Dürer's engravings and woodcuts, he must have found it profitable. His early copies included Dürer's famous AD monogram, and Dürer made a complaint to the Venetian Government, which won him some legal protection for his monogram, but not his compositions, in Venetian territory - an important case in the slowly evolving history of intellectual property law. Marcantonio appears to have spent some of the last half of the decade in Venice, but no dates are known. Rome Around 1510, Marcantonio travelled to Rome and entered the circle of artists surrounding Raphael. This influence began showing up in engravings titled The Climbers (in which he reproduced part of Michelangelo's Soldiers surprised bathing, also called Battle of Cascina). After a reproduction of a work by Raphael, entitled Lucretia, Raphael trained and assisted Marcantonio personally. Another famous engraving, the Judgement of Paris, dated 1515 or 1516, after Raphael, became the composition source for Édouard Manet when he painted The Luncheon on the Grass. The two started a successful printing establishment under a colorgrinder, Il Baveria, that quickly expanded into an engraving school with Marcantonio at the head. Among his most distinguished pupils were Marco Dente (Marco da Ravenna), Giovanni Jacopo Caraglio and Agostino de Musi (Agostino Veneziano). Later years Marcantonio and his pupils continued to make engravings based upon Raphael's work, even after Raphael's death in 1520. In many instances, Marcantonio would not copy the finished painting, but instead worked from early sketches and drafts. This method produced variations on a theme and were moderately successful. Around 1524, Marcantonio was briefly imprisoned by Pope Clement VII for making the I modi set of erotic engravings, from the designs of Giulio Romano, which were later accompanied by sonnets written by Pietro Aretino. At the intercession of the Cardinal Ippolito de' Medici, Baccio Bandinelli and Pietro Aretino, he was released, and set to work on his plate of the Martyrdom of St. Lawrence after Bandinelli.
