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.
List of Christmas operas
The first Christmas operas, dating from the early 17th century, had librettos based on the Nativity of Jesus and were privately performed. At various times well into the 19th century, public theatres in Italy and other Catholic countries were closed during the season of Advent, the four weeks up to and including Christmas Eve. The opera season customarily recommenced on St. Stephen's Day, 26 December. Numerous world premieres have taken place in Italy on that day, although all were on secular subjects and unrelated to Christmas. The prohibition of secular theatrical performances during Advent was to some extent circumvented by the performance of "azioni sacre", operas on religious themes, often with elaborate staging. One of the earliest Christmas operas of this type was Giovanni Battista da Gagliano and Jacopo Peri's "Il gran natale di Christo salvator nostro" (The Great Nativity of Christ, Our Saviour), first performed on Christmas Day 1622.
