Andrealphus (also Androalphus) appears as the 54th demon in Johann Weyer's tome on demonology Pseudomonarchia Daemonum. He is described as a great Marquis of Hell with the appearance of a peacock who raises great noises and teaches cunning in astronomy, and when in human form also teaches geometry in a perfect manner.


He is described as ruling over thirty legions as well as having the ability to turn any man into a bird. Andrealphus also appears as the 65th demon in the Goetia where he is described with similar traits, but also including the ability to make men subtle in all things pertaining to Mensuration, among other things.

Andrealphus in Christian and Occult Demonologies[]

Throughout history multiple formalized classifications of demons have been proposed. None of them however are considered canon by modern mainstream Christian denominations. Instead, lists of formalized demonologies tend to remain popular in occult traditions.

Andrealphus in the Pseudomonarchia Daemonum[]

The Pseudomonarchia daemonum, or False Monarchy of Demons, by the Dutch occultist Johann Weyer, was published as an appendix to his book titled De praestigiis daemonum, or On the Tricks of Demons, in 1577. The description of Andrealphus from the Pseudomonarchia daemonum is as follows:

Andrealphus [*Androalphus] is a great marquesse, appearing as a pecocke, he raiseth great noises, and in humane shape perfectlie teacheth geometrie, and all things belonging to admeasurements, he maketh a man to be a subtill disputer, and cunning in astronomie, and transformeth a man into the likenes of a bird, and there are under him thirtie legions.[1]

Andrealphus in the Lemegeton Clavicula Salomonis (Ars Goetia)[]

The Lemegeton Clavicula Salomonis or Lesser Key of Solomon is an anonymously written book of demonology that is believed to have been complied sometime during the 17th century CE. The work is divided into five books, the first of which, known as the Ars Goetia, lists seventy-two demons. The Ars Goetia is heavily based off of Johann Weyer's Pseudomonarchia daemonum.

In 1904, the British occultist and founder of the religion of Thelema, Aleister Crowley, published a version of the Lesser Key of Solomon which was translated by another British occultist, Samuel Liddell MacGregor Mathers, and contained additional invocations added by Crowley. The Ars Goetia's passage on Andrealphus from the 1904 version is as follows:

The Sixty-fifth Spirit is Andrealphus. He is a Mighty Marquis, appearing at first in the form of a Peacock, with great Noises. But after a time he putteth on Human shape. He can teach Geometry perfectly. He maketh Men very subtle therein; and in all Things pertaining unto Mensuration or Astronomy. He can transform a Man into the Likeness of a Bird. He governeth 30 Legions of Infernal Spirits, and his Seal is this, etc.[2]

Andrealphus in the Dictionnaire Infernal[]

The Infernal Dictionary is a book of demonology written in 1818 by the French occultist Jacques Auguste Simon Collin de Plancy. The entry for Andrealphus (Androalphus) is as follows:

Androalphus, mighty demon, marquis of the infernal empire; he appears as a peacock with a deep voice. When he appears in human form, he can be compelled to give lessons in geometry. He is an astronomer, and he also teaches quibbling skillfully. He gives men the figures of birds; which allows those who trade with him to avoid the claw of the judges. Thirty legions are under his command.[3]
