There is a Circe episode in John Harbison's "Ulysses" (Act 1, scene 2, 1983) in which the song of the enchantress is represented by ondes Martenot and tuned percussion. After the sailors of Ullyses are transformed into animals by her spell, a battle of wills follows between Circe and the hero. Though the men are changed back, Ulysses is charmed by her in his turn. In 1993, a full scale treatment of the story followed in Gerald Humel's two-act "Circe und Odysseus". Also psychological in intent, it represents Circe's seduction of the restless hero as ultimately unsuccessful. The part played by the geometrical set in its Berlin production was particularly notable.
