Gamigin

Gamigin is a demon described in demonological grimoires such as The Lesser Key of Solomon (the fourth Goetic demon; referred to in the Crowley/Mathers edition as Samigina) and Johann Weyer's Pseudomonarchia Daemonum (the forty-sixth; referred to as Gamygyn).

Both works describe him as a marquis who initially takes the form of a small horse before transforming into a hoarse-voiced human. The Lesser Key of Solomon merely leaves his duties at teaching liberal arts and giving accounts of souls that died in sin.
