Andrealphus

Teaches geometry and measurements (conversions?). Increases one's intelligence. Can transform a person into a bird.

This reminds me of the story of Nephthys and Isis taking the form of falcons after the death of Osiris to find all the pieces of him.

It also reminds me of a manifesto I wrote in the height of my career about Seth disguised as a bird in order to Conquer this or that.

A great marquis in the hosts of Hell, Andrealphus is siad to take the form of a peacock. He can transform men into birds. In addition to this he can teach geometry, astronomy, and any discipline dealing with measurement. He appears in both Wierus's Pseudomonarchia Daemonum and Scot's Discoverie of Witchcraft, where he is said to govern thirty legions. Andrealphys is also one of seventy-two demons listed in the Goetia. In the Goetia of Dr. Rudd, he is said to be constrained in the name of angel Demabiah. The Welsh Book of Incantations says he can transform into a bird. See also BOOK OF INCANTATIONS, GOETIA, RUDD, SCOT, WEIRUS.
