"Prometeo" is perhaps the ultimate realisation of Nono's "theatre of consciousness"—here, an invisible theatre in which the production of sound and its projection in space become fundamental to the overall dramaturgy. The architect Renzo Piano designed an enormous 'wooden boat' structure for the première at San Lorenzo church in Venice, whose acoustics must to some extent be reconstructed for each performance. (For the Japanese première at the Akiyoshidai Festival (Shuho), the new concert hall was named 'Prometeo Hall' in Nono's honour, and designed by leading architect Arata Isozaki). The libretto incorporates disparate texts by Hesiod, Hölderlin, and Benjamin (mostly logistically inaudible during performance due to Nono's characteristic deconstruction), which explore the origin and evolution of humanity, as compiled and expanded by Cacciari. In Nono's timeless and visionary context, music and sound predominate over the image and the written word to form new dimensions of meaning and "new possibilities" for listening.
