Goetia – S. L. MacGregor Mathers (1904) (quoted)

Purson’s Goetic Seal

 
The Twentieth Spirit is Purson, a Great King. His appearance is comely, like a Man with a Lion’s face, carrying a cruel Viper in his hand, and riding upon a Bear. Going before him are many Trumpets sounding. He knoweth all things hidden, and can discover Treasure, and tell all things Past, Present, and to Come. He can take a Body either Human or Aërial, and answereth truly of all Earthly things both Secret and Divine, and of the Creation of the World. He bringeth forth good Familiars, and under his Government there be 22 Legions of Spirits, partly of the Order of Virtues and partly of the Order of Thrones. His Mark, Seal, or Character is this, unto the which he oweth obedience, and which thou shalt wear in time of action, etc.
The picture of Purson in Mather’s Goetia corresponds with Pruflas in the Dictionnaire Infernal. The Goetia does not include Pruflas in its list ofdemons. However, both Purson and Pruflas are listed in Wier’s list, and only Pruflas is listed in de Plancy’s list. (See comparison page for details.)

Pseudomonarchia daemonum – Johann Wier (1583) (quoted)
Purson [Pursan], alias Curson, a great king, he commeth foorth like a man with a lions face, carrieng a most cruell viper, and riding on a beare; and before him go alwaies trumpets, he knoweth things hidden, and can tell all things present, past, and to come: [he discloses hidden things,] he bewraieth treasure, he can take a bodie either humane or aierie; he answereth truelie of all things earthlie and secret, of the divinitie and creation of the world, and bringeth foorth the best familiars; and there obeie him two and twentie legions of divels, partlie of the order of vertues, & partlie of the order of thrones.
