For voice and piano. Libretto by the composer, based on Virgil's Aeneid. Les Troyens consists of two parts: pt.1, La prise de Troie (2 acts) and pt.2, Les Troyens à Carthage (originally 3 acts, which the composer later broke into 5, adding a prologue so that it could be performed separately) Pt.2. has been produced under the somewhat misleading title Les Troyens (since this is really the title of the whole) Cf.
