Œdipe is an opera in four acts by the Romanian composer George Enescu (1881–1955), based on the mythological tale of Oedipus, and set to a French libretto by Edmond Fleg.
Enescu had the idea to compose an Oedipus-inspired opera even before finding a libretto and began to sketch music for it in 1910. The first-draft libretto from Fleg arrived in 1913. Enesco completed the music in 1922 and the orchestration in 1931. The opera received its world premiere in Paris on 13 March 1936. The first German production was in Berlin in 1996, in a production that subsequently traveled to the Vienna State Opera. The United States premiere was in 2005 at the University of Illinois at Urbana-Champaign.
This dramatic musical treatment of the Oedipus myth is unusual in that it attempts to cover the entire story of Oedipus' life, from birth to death. Act III covers the story of Oedipus the King. Act IV overlaps in plot with Oedipus at Colonus, though with divergent psychological treatment of Oedipus' final days compared to the original. It is generally considered to be Enescu's masterpiece.
