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.
Italian opera
Opera took an important new direction when it reached the republic of Venice. It was here that the first public opera house, the Teatro di San Cassiano, was opened in 1637 by Benedetto Ferrari and Francesco Manelli. Its success moved opera away from aristocratic patronage and into the commercial world. In Venice, musical drama was no longer aimed at an elite of aristocrats and intellectuals and acquired the character of entertainment. Soon many other opera houses had sprung up in the city, performing works for a paying public during the Carnival season. The opera houses employed a very small orchestra to save money. A large part of their budget was spent on attracting the star singers of the day; this was the beginning of the reign of the castrato and the prima donna (leading lady).
