A great king of the Goetia, 'very obedient unto Lucifer,' commanding two hundred legions — and the tradition's most theatrical arrival. He comes as a crowned man with an effeminate face, riding a dromedary, preceded by a host of spirits 'with trumpets and well-sounding cymbals, and all other sorts of musical instruments.' The grimoires warn that his first voice is a roar too great to understand, and the operator must require him to speak plainly.
His documented offices are scholarly: he teaches 'all arts, philosophies and sciences,' reveals what holds the earth up, gives good familiars, and can bind others to the operator's will — which is why the texts rank him among the seats most sought and most cautioned.
Ari Aster's Hereditary (2018) put the name back in circulation, and the archive's standing note applies: the film's cult and rites are fiction; the historical Paimon is a catalog entry in Weyer and the Lesser Key, arriving to cymbals, lecturing on philosophy.
