(b Rome, 26 Nov 1491; d Rome, 22 Jan 1557).
Italian banker and patron. He was born of a noble Florentine family. At the age of 16 he inherited the family bank in Rome and, after the closure in 1528 of the rival bank founded by Agostino Chigi, became the most important papal financier in the city. Despite his position as Florentine consul in Rome, he was vigorously opposed to the Medici regime and his residence near the Ponte Sant’Angelo became the gathering place of many Florentine exiles. This palazzo was restored by Altoviti in 1514 (destr. 1888) and housed a rich collection of antiquities from Hadrian’s Villa and many commissioned works.
