According to Ariosto's lesser work "I Cinque Canti", Demogorgon has a splendid temple palace in the Imavo mountains (today's Himalaya) where every five years the Fates and genii are all summoned to appear before him and give an account of their actions. They travel through the air in various strange conveyances, and it is no easy matter to distinguish between their convention and a Witches' Sabbath. When elements of Ariosto's poem supplied Philippe Quinault's libretto for Jean-Baptiste Lully's opera "Roland", performed at Versailles, 8 January 1685, Demogorgon was king of the fairies and master of ceremonies.
