Pseudomonarchia Daemonum

Blurb

Pseudomonarchia Daemonum, or Hierarchy of Demons first appears as an Appendix to Johann Weyer's De praestigiis daemonum. The title of the book translates roughly to "false monarchy of demons".
An abridgement of a grimoire similar in nature to the Ars Goetia, the first book of The Lesser Key of Solomon, it contains a list of demons, and the appropriate hours and rituals to conjure them.
The book was written before The Lesser Key of Solomon, and has some differences. There are sixty-nine demons listed, and the order of the spirits varies, as well as some of their characteristics. The demons Vassago, Seere, Dantalion and Andromalius are not listed in this book, while Pruflas is not listed in The Lesser Key of Solomon. Pseudomonarchia Daemonum does not attribute seals to the demons, as The Lesser Key of Solomon does.
Weyer referred to his source manuscript as Liber officiorum spirituum, seu Liber dictus Empto. Salomonis, de principibus et regibus daemoniorum.. This work is likely related to a very similar 1583 manuscript titled "The Office of Spirits", both of which appear ultimately be an elaboration on a fifteenth-century manuscript titled Le Livre des Esperitz.
