In demonology, and according to Johann Weyer and his Pseudomonarchia Daemonum, Pruflas is a Great Prince and Duke of Hell.
Other spelling: Bufas.
Pruflas is a Great Prince and Duke of Hell with twenty-six legions of demons under his command. Pruflas is not listed in the Ars Goetia of The Lesser Key of Solomon but might be known as Purson.
Pruflas causes and promotes quarrels, discord, and falsehood, and should be never admitted into any place, but if conjured, he gives generous answers to the conjurer's questions.
Pruflas is depicted as a flame outside the Tower of Babel, where he uses to reside, and sometimes his head is seen as that of a hawkan owl.
Pruflas otherwise found as Bufas, is a great prince and duke, whose abode is around the Tower of Babylon, and there he is seen like a flame outside. His head however is like that of a great night hawk. He is the author and promoter of discord, war, quarrels, and falsehood. He may not be admitted into every place. He responds generously to your requests. Under him are twenty-six legions, partly of the order of Thrones, and partly of the order of Angels. Pseudomonarchia daemonum - Johann Wier (1583)
