Amaimon: In the Sacred Magic of Abramelin the Mage, Amaimon is said to know the past, present, and future. He can cause visions and enable people to fly. He provides familiar spirits and can cause other spirits to appear and assume diverse forms. He can summon protection and revive the dead.
The Abramelin material identifies him as one of the four infernal rulers of the cardinal directions.
His domain is the south. In this text, he is one of eight sub-princes summoned to serve the magician as part of the Holy Guardian Angel rite. Mathers relates his name to a Greek root meaning “terrible violence and vehemence.” According to both Mathers and Agrippa, Amaimon's equivalent in Jewish lore is the demon Mahazael.
Scot's Discoverie of Witchcraft mentions that Amaimon is known for his dangerous, putrid breath and describes a
technique of protection where conjurors wear a magick ring and hold this against their faces to ward away Amaimon's harm. The same technique is advised for the infernal king Bileth. Mathers also notes Amaimon's reputation for fiery or poisonous breath.
He appears in Wierus's Pseudomonarchia Daemonum under the name Amaymonis. Here he seems to be a chief among evil spirits. He is mentioned in connection with both Asmodeus and Bileth, and he is tied to deception and abominable practices. Although he is associated with the south in the Abramelin material, Amaimon is listed as the “King of the East” in Dr. Rudd's Treatise on Angel Magic. Here, the name of this demon is rendered Amaymon.
