Jacopo Carucci, usually known as Jacopo da Pontormo, Jacopo Pontormo, or simply Pontormo, was an Italian Mannerist painter and portraitist from the Florentine School. His work represents a profound stylistic shift from the calm perspectival regularity that characterized the art of the Florentine Renaissance. He is famous for his use of twining poses, coupled with ambiguous perspective; his figures often seem to float in an uncertain environment, unhampered by the forces of gravity.
