Some composers wrote their own libretti. Richard Wagner is perhaps most famous in this regard, with his transformations of Germanic legends and events into epic subjects for his operas and music dramas. Hector Berlioz, too, wrote the libretti for two of his best-known works, "La damnation de Faust" and "Les Troyens". Alban Berg adapted Georg Büchner's play "Woyzeck" for the libretto of "Wozzeck".
