Origins of opera
"Dafne" by Jacopo Peri was the earliest composition considered opera, as understood today, although with only five instrumental parts it was much more like a chamber opera than either the preceding intermedi or the operas of Claudio Monteverdi a few years later. It was written around 1597, largely under the inspiration of an elite circle of literate Florentine humanists who gathered as the "Camerata". Significantly, "Dafne" was an attempt to revive the classical Greek drama, part of the wider revival of antiquity characteristic of the Renaissance. The members of the Camerata considered that the "chorus" parts of Greek dramas were originally sung, and possibly even the entire text of all roles; opera was thus conceived as a way of "restoring" this situation. The libretto was by Ottavio Rinuccini, who had written some of the 1587 Medici intermedi, in which Peri had also been involved; Rinuccini appears to have recycled some of the material, at least from the scene illustrated at right. Most of the music for "Dafne" is lost (the libretto was printed and survives), but one of Peri's many later operas, "Euridice", dating from 1600, is the first opera score to have survived to the present day.

Bellini's first opera was written as his final project at the Naples San Sebastiano Conservatory, when the composer was 23 years old. It was the custom at the Conservatory to introduce promising students to the public with a dramatic work. Bellini styled his project an "opera semi-seria", and it was first performed at the "Teatro del Conservatorio di San Sebastiano" in Naples sometime between mid-January and mid-March 1825, although David Kimbell states 12 February 1825. Weinstock attributes the uncertainty as to the exact date to a series of deaths of several prominent people (including Bourbon King Ferdinand I), which caused all public entertainment to stop during periods of mourning.
