The Thirty-second Spirit is Asmoday, or Asmodai. He is a Great King, Strong, and Powerful. He appeareth with Three Heads, whereof the first is like a Bull, the second like a Man, and the third like a Ram; he hath also the tail of a Serpent, and from his mouth issue Flames of Fire. His Feet are webbed like those of a Goose. He sitteth upon an Infernal Dragon, and beareth in his hand a Lance with a Banner. He is first and choicest under the Power of AMAYMON, he goeth before all other. When the Exorcist hath a mind to call him, let it be abroad, and let him stand on his feet all the time of action, with his Cap or Headdress off; for if it be on, AMAYMON will deceive him and call all his actions to be bewrayed. But as soon as the Exorcist seeth Asmoday in the shape aforesaid, he shall call him by his Name, saying: "Art thou Asmoday?" and he will not deny it, and by-and-by he will bow down unto the ground. He giveth the Ring of Virtues; he teacheth the Arts of Arithmetic, Astronomy, Geometry, and all handicrafts absolutely. He giveth true and full answers unto thy demands. He maketh one Invincible. He showeth the place where Treasures lie, and guardeth it. He, amongst the Legions of AMAYMON governeth 72 Legions of Spirits Inferior. His Seal is this which thou must wear as a Lamen upon thy breast, etc.
Sacred Magic of Abra-Melin the Mage - SL MacGregor Mathers (1898) (quoted)
Asmodee: Usually written "Asmodeus," and sometimes "Chashmodai". Derived by some from the Hebrew word "Asamod," to destroy or exterminate; and by others from the Persian verb "Azmonden," = to tempt, to try or prove. Some Rabbins say that Asmodeus was the child of the incest of Tubal-Cain and his sister Naafrfah. Others say that he was the Demon of impurity. Others again relate that he was employed by Solomon in the building of the Temple at Jerusalem; that he then attempted to dethrone Solomon, to put himself in his place; but that the King vanquished him and the Angel Gabriel chased him into Egypt, and there bound him in a Grotto. The Rabbins say that when Asmodeus was working at the building of the Temple, he made use of no metal tool; but instead of a certain stone which cut ordinary stone as a diamond will glass.
