Les Boréades

Les Boréades is the final opera composed by Jean-Philippe Rameau (1683–1764). The work takes the form of a tragédie lyrique in five acts. The libretto, attributed to Louis de Cahusac (1706–1759), is loosely based on the Greek legend of Abaris the Hyperborean and includes Masonic elements; the Boréades are the descendants of Boréas. Though evidently rehearsed in 1763, the work was yet unperformed by Rameau's death in 1764.
