Apart from a comic opera called Die Studenten von Salmanca (The Students of Salamanca), he concentrated on two epic tetralogies based on the Iliad and the Odyssey entitled Homerische Welt (The Homeric World).
The tetralogy mentioned above has been published in English translation by Keith Waldrop as : Reversal (1973); The Notion of Obstacle (1985), and Objects Contain the Infinite (1995).
John Culshaw, the Decca recording producer, was disappointed with the performances of the first three operas in the tetralogy, but was impressed by the Götterdämmerung and edited up a version of it but Decca did not release it.
Again returning home, he astonished the musical community with the production in Antwerp of a sacred tetralogy, consisting of his Cantate de Noël, the above-mentioned Mass, a Te Deum and a Requiem, in which were embodied to a large extent his theories about Flemish music.
Rendez-vous à Paris is a French comic book by Enki Bilal, and the third album of the tetralogy featuring Nike Hatzfeld.
