Andrea del Sarto
The early Mannerists in Florence, especially the students of Andrea del Sarto such as Jacopo da Pontormo and Rosso Fiorentino, are notable for elongated forms, precariously balanced poses, a collapsed perspective, irrational settings, and theatrical lighting. As the leader of the First School of Fontainebleau, Rosso was a major force in the introduction of Renaissance style to France.
