Polidoro da Caravaggio
Polidoro was born in about 1499 in the town of Caravaggio, near Milan, in northern Italy. He moved to Rome around 1515 and was probably engaged in Raphael's workshop from 1517. After Raphael's death in 1520, Polidoro occasionally collaborated with his former fellow assistants, but he soon began to specialize in painting friezes on the façades of Roman palaces. Although very little remains of these schemes, in their day they were among the most copied and widely known paintings in Italy.
After the Sack of Rome in 1527, Polidoro left for Naples, then moved on to Sicily a year later. The rest of his career is poorly documented. Isolated from the artistic developments in central and northern Italy, his drawing and painting style evolved into a highly individual, expressive idiom, and his subsequent paintings were almost all devotional in nature. Polidoro was apparently murdered by an assistant in 1543.
