Abas: In the Sacred Magic of Abramelin the Mage, Abas is listed as a demon of lies and trickery. He can be called upon to assist the magician in matters dealing with illusion as well as spells of invisibility. This demon also appears in the Mathers translation of the Clavicula Salomonis with the same associations.

According to Driscoll’s edition of the Sworn Book, Abas is the king of the regions below the earth. His province includes the riches of the earth, and he is said to be able to locate and provide all manner of costly metals, including silver and gold. Additionally, he seems to be able to cause earthquakes, for it is said that he can pull down buildings and other structures and cause them to be destroyed. Finally, Abas and his minions can teach knowledge of the mixture of the elements, a possible reference to alchemy, although alchemical workings are not specifically described within the text. In the Clavicula Salomonis, the name of this demon is spelled Abac.
