The operas of Per Nørgård (b. 1932) embody a search for hidden wisdom and spiritual transcendence characteristic of artists who came to maturity during the 1960s. Gilgamesh (1972) and Nuit des hommes (1996) can be perceived as mirror images that embody visions of universal harmony and discord, and of spiritual wholeness and disintegration. This article analyses Nørgård's use of mythic paradigms and Jungian archetypes to structure the operas. It also examines Nørgård's use of dialectical polarities, including creation and death, the human and the divine, and self and others. In particular, it discusses two concepts derived from the work of Joseph Campbell, the ‘hero's journey’ and the ‘cosmogonic cycle’, linking them to Jung's theory of individuation. While Gilgamesh embodies a successful realisation of the hero's journey, the characters in Nuit des hommes become directionless wayfarers in a hostile world.
