Cristoforo Caradosso Foppa is first noted in 1475 working in Milan as a goldsmith and medalist. He remained there after the fall of Ludovico II Moro, then went to Rome via Mantua in 1505. Although there is no documentation of him at the papal mint, Caradosso made several medals of Julius II and helped found in 1509 the Guild of Roman Goldsmiths. None of his medals are signed, and attributions to him are based on the word of Vasari and Lomazzo.
