Mozart's "Idomeneo" Is First Performed

Idomeneo, re di Creta ossia Ilia e Idamante (Italian for Idomeneo, King of Crete, or, Ilia and Idamante; usually referred to simply as Idomeneo, K. 366) is an Italian language opera by Wolfgang Amadeus Mozart.

The libretto was adapted by Giambattista Varesco from a French text by Antoine Danchet, which had been set to music by André Campra as Idoménée in 1712. Mozart and Varesco were commissioned in 1780 by Karl Theodor, Elector of Bavaria for a court carnival. He probably chose the subject, though it might have been Mozart.
