Metamorphoses

Isis, which premiered January 5, 1677, at St. Germain-en-Laye, was the fifth of Jean-Baptiste Lully's tragédies lyriques written with librettist Philippe Quinault. The plot is loosely adapted from one of the episodes in Ovid's Metamorphoses. In many of its essentials, the plot of Isis resembles that of Lully's previous opera, Atys. In Isis, the nymph Io, daughter of the river Inachus, is promised in marriage to Hierax, just as the nymph Sangaride, daughter of the river Sangar, was promised to Celoenus. Like Sangaride, Io is pursued by another love and yields to this love in spite of her feelings of guilt. Like Sangaride, Io has a goddess as a rival and is vulnerable to her jealousy. Lully's contemporaries interpreted this story as representing the volatile situation between two of the King's mistresses. The subsequent scandale of the premiere ended the collaboration between Lully and Quinault for a time, and led to the dismissal of a number of members of Lully's artistic circle
