an Italian painter of the Florentine Renaissance. He was born in Florence, and initially worked under Albertinelli until about 1506. In 1505 he befriended Andrea del Sarto; and by the next year, the two painters set up common shop in the Piazza del Grano. He was proficient in fresco and Vasari claimed that he surpassed all his contemporaries in this method. It's in his portraits, and not his religious paintings and frescoes, that his painting gathers naturalistic power.
