Isis (Lully)
Isis is an opera by Jean-Baptiste Lully. The librettist is Lully's frequent collaborator, Philippe Quinault, and like most of Lully's operas, it is a tragédie lyrique. It premièred January 5, 1677 at the court of Saint-Germain-en-Laye and was first published in 1719.
The story of the opera centers around the god Jupiter's love for the nymph Io and the jealousy of Juno. She has Io imprisoned and tortured, leading Io to cry out to Jupiter for help. He swears faithfulness to Juno if she will spare Io, and Juno turns Io into a goddess: Isis, the Egyptian goddess.
