Nicknamed "Zazzerino," Jacopo Peri (1561-1633) is credited, along with Corsi librettist Rinuccini, with creating the first true opera, Dafne, of which only fragments remain. The oldest surving opera, Euridice, is likewise a Peri collaboration with Rinuccini. It is thought that he also sang the role of Orpheus. Peri was also a church organist and wrote ballets, madrigals, and instrumental music.
