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.
Achilles on Skyros
One of the earliest and best studied Renaissance versions of the story was Tirso de Molina's 1612 play "El Aquiles". It was followed by a number of other Spanish plays on the same topic. One of its foci was the change in Achilles from fleeing war to being a war hero. This was emphasized by the many changes and transformations used in the play. But the more typical themes of gender confusion and homosexual love are also apparent, and strengthened by the indication that the role of Achilles should be played by a woman.
It has often been used as the theme for an opera or ballet, with the libretto by Metastasio as the most popular. The first opera based on this story seems to have been "La finta pazza" by Francesco Sacrati, with a libretto by Giulio Strozzi. It was the first and probably the most popular opera of the seventeenth century. It was first performed at the inauguration in 1641 of the Teatro Novissimo in Venice, the first time ever a building was created specifically to perform operas. Anna Renzi was the main singer. The production then was performed many times all over Italy and abroad, including a 1645 performance in Paris, which was the second time ever that an opera was staged in France.
