Are Norma and Idomeneo both operas by Bellini?
Idomeneo Idomeneo, re di Creta ossia Ilia e Idamante (Italian for "Idomeneus, King of Crete, or, Ilia and Idamante"; usually referred to simply as Idomeneo, K. 366) is an Italian language opera seria 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. The work premiered on 29 January 1781 at the Cuvilliés Theatre in Munich, Germany.
Origins of opera The art form known as "opera" originated in Italy in the sixteenth and seventeenth centuries, though it drew upon older traditions of medieval and Renaissance courtly entertainment. The word "opera", meaning "work" in Italian, was first used in the modern musical and theatrical sense in 1639 and soon spread to the other European languages. The earliest operas were modest productions compared to other Renaissance forms of sung drama, but they soon became more lavish and took on the spectacular stagings of the earlier genre known as intermedio.
