Zaïs
Zaïs is an opera by Jean-Philippe Rameau first performed on 29 February 1748 at the Opéra in Paris. It takes the form of a pastorale héroïque in four acts and a prologue. The librettist was Louis de Cahusac.
The score is particularly remarkable for its overture, which depicts the emergence of the four elements out of chaos. It looks back to Jean-Féry Rebel's ballet Les élemens and forward to Haydn's overture for his oratorio The Creation.
