Astaroth is the twenty-ninth spirit listed in the Ars Goetia. He is an exceptionally powerful Duke of Hell assisted by four demons: Aamon, Barbatos, Rashaverak and Pruflas. He is depicted as a naked man with a dragon's hands, feet and wings, a secondary pair of angel's wings, wearing a crown, holding a serpent and riding a wolf.

He can seduce men through laziness and vanity, make men wise in mathematical sciences and handicrafts, reveal hidden treasures, make men invisible and give them power over serpents.

He is sometimes referred to as the prince of accusers and inquisitors, with powers to rival that of the great demons Bael and Beelzebub. His name is derived from the Canaanaite goddess Ashtoreth (or Astarte in Greek). Indeed, Astaroth frequently mentions that he wishes to return to being the fertility goddess Ishtar; an appropriate homage to the origin of his name.
