Platée

thumb|Jean-Philippe Rameau Platée is an opera in a prologue and three acts by Jean-Philippe Rameau with a libretto by Adrien-Joseph Le Valois d'Orville. Rameau bought the rights to the libretto Platée ou Junon jalouse (Plataea, or Juno Jealous) by Jacques Autreau (1657–1745) and had d'Orville modify it. The ultimate source of the story is a myth related by the Greek writer Pausanias in his Guide to Greece.

Rameau's first attempt at comic opera, the plot concerns an ugly water nymph who believes that Jupiter, the king of the gods, is in love with her. The work was initially called a ballet bouffon, though it was later styled a comédie lyrique, putting it in the same category as Rameau's Les Paladins. It was written for the celebrations of the wedding of Louis, Dauphin of France, son of King Louis XV, to the Infanta María Teresa Rafaela of Spain, who, according to contemporary sources, like the title character was no beauty. Instead of getting the composer into trouble, the entertainment at Versailles seems to have been well received, and Rameau was appointed a few months later to the position of Composer of the King's Chamber Music with a sizable annual pension.
