Le Roi D’Ys
Opera by Lalo, produced at the Opéra Comique in 1888, and given in London in 1901. The story is founded upon a Breton legend. Margared and Rozenn, daughters of the King of Ys, love Mylio. But the warrior has only eyes for Rozenn. In revenge Margared betrays her father’s city to Karnac, a defeated enemy. To him she gives the keys of the sluices which stand between the town and the sea. When the town and all its inhabitants are about to be swept away, the girl in remorse throws herself into the sea. St. Corentin, patron saint of Ys, accepts her sacrifice and the sea abates.
