Astaroth

He is referred to in The Lesser Key of Solomon as a very powerful deity. His main assistants are four demons called Aamon, Pruslas, Barbatos and Rashaverak. In art, in the Dictionnaire Infernal, Astaroth is depicted as a nude man with dragon-like wings, hands and feet, a second pair of feathered wings after the main, wearing a crown, holding a serpent in one hand, and riding a wolf or dog. According to Sebastien Michaelis he is a demon of the First Hierarchy, who seduces by means of laziness and vanity, and his adversary is St. Bartholomew, who can protect against him for he has resisted Astaroth's temptations. To others, he teaches mathematical sciences and handicrafts, can make men invisible and lead them to hidden treasures, and answers every question formulated to him. He was also said to give to mortal beings the power over serpents.

According to Francis Barrett (occultist), Astaroth is the prince of accusers and inquisitors. According to some demonologists of the 16th century, August is the month during which this demon's attacks against man are stronger. He also goes by the name ‘Ashtart/Astarte which was rendered in the Latin Vulgate translation of the Bible as Astharthe (singular) and Astharoth (plural), that last form rendered in the King James Version of the Bible as Ashtaroth. It seems this plural form was taken either from the Latin or from some translation or other by those who did not know it was a plural form.

According to Lon Milo DuQuette and Christopher S. Hyatt, Astaroth is "a thinly disguised version of the goddess Astarte...." Jeff Rovin's The Fantasy Encyclopedia (1979) depicted Astaroth with a likeness fitting the description of Baal, including a newly-created illustration, and this error has been repeated in other places, such as with Monster in My Pocket, in which a spidery, 3-headed Astaroth is #102
