The most important figures were Giulio Romano, a young pupil from Rome (only about twenty-one at Raphael's death), and Gianfrancesco Penni, already a Florentine master. They were left many of Raphael's drawings and other possessions, and to some extent continued the workshop after Raphael's death. Penni did not achieve a personal reputation equal to Giulio's, as after Raphael's death he became Giulio's less-than-equal collaborator in turn for much of his subsequent career. Perino del Vaga, already a master, and Polidoro da Caravaggio, who was supposedly promoted from a labourer carrying building materials on the site, also became notable painters in their own right. Polidoro's partner, Maturino da Firenze, has, like Penni, been overshadowed in subsequent reputation by his partner. Giovanni da Udine had a more independent status, and was responsible for the decorative stucco work and grotesques surrounding the main frescoes. Most of the artists were later scattered, and some killed, by the violent Sack of Rome in 1527. This did however contribute to the diffusion of versions of Raphael's style around Italy and beyond.
