 One was a large-scale stage work called by different names at different times, but principally "The One-All-Alone" or "Astronomer" ("L'Astronome").This was originally to be based on North American Indian legends; later it became a futuristic drama of world catastrophe and instantaneous communication with the star Sirius.This second form, on which Varèse worked in Paris in 1928–1932, had a libretto by Alejo Carpentier, Georges Ribemont-Dessaignes and Robert Desnos.
