In accordance with the Florentine tradition, he studied with numerous artiststhe works of the great masters of previous periods, as well as the works of his contemporaries, such as Leonardo, Michelangelo and Raphael. Early in his life, he became independent and opened a painting workshop, the first one with the painter Franciabigio, and later in the second one the sculptor Jacopo Sansovino joined them. He was a member of several compagnie di piacere for which, among other things, he also worked on scenography for theatre plays.106 The versatile painter with a rich oeuvre, he also constantly created numerous preparatory drawings for the final works.
