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.
Orion (mythology)
Italian composer Francesco Cavalli wrote the opera, "L'Orione" in 1653. The story is set on the Greek island of Delos and focuses on Diana's love for Orion as well as on her rival, Aurora. Diana shoots Orion only after being tricked by Apollo into thinking him a sea monster—she then laments his death and searches for Orion in the underworld until he is elevated to the heavens. Johann Christian Bach ('the English Bach') wrote an opera, "Orion, or Diana Reveng'd", first presented at London's Haymarket Theatre in 1763. Orion, sung by a castrato, is in love with Candiope, the daughter of Oenopion, King of Arcadia but his arrogance has offended Diana. Diana's oracle forbids him to marry Candiope and foretells his glory and death. He bids a touching farewell to Candiope and marches off to his destiny. Diana allows him his victory and then kills him, offstage, with her arrow. In another aria, his mother Retrea (Queen of Thebes), laments his death but ultimately sees his elevation to the heavens. The 2002 opera "Galileo Galilei" by American composer Philip Glass includes an opera within an opera piece between Orion and Merope. The sunlight, which heals Orion's blindness, is an allegory of modern science. Philip Glass has also written a shorter work on Orion, as have Tōru Takemitsu, Kaija Saariaho, and John Casken. David Bedford's late-twentieth-century works are about the constellation rather than the mythical figure; he is an amateur astronomer.
