What is "amaymon"

In demonology, Amaymon (also Amaimon, or Amoymon) is a Prince of Hell, and, according to some Grimoires, the only one who has power over Asmodai.

A curious characteristic of this Spirit is shown during the Evocation of Asmodai to visible appearance, when the Exorcist must stand upright with his Cap or Headdress removed in a show of respect; for if he does not it is Amaymon who will deceive him and doom all his work.

Amaymon is said to have a deadly poisonous breath.

The Lesser Key of Solomon states the Exorcist or conjurer must be in possession of a Silver Ring, duly consecrated and worn on the middle finger as a form of protection against this poisonous astral breath.

According to Pseudomonarchia Daemonum he is the King of the West, although for some translations of The Lesser Key of Solomon he is King of the East (Although some translations of The Lesser Key of Solomon consider Belial, Beleth, Asmodai and Gaap kings of the four cardinal directions, though not giving detail on the cardinal point each rule).

According to the grimoire The Book of the Sacred Magic of Abramelin the Mage translated by S.L. MacGregor Mathers, Amaymon (as Amaimon) was one of the eight Sub-Princes, described as an Egyptian devil whom Abramelin restrained from working evil from the third hour till noon and from the ninth till evening.
