This book was written in the 16th century, before The Lesser Key of Solomon, and has some differences. There are sixty-eight demons listed (instead of seventy-two), and the order of the spirits varies, as well as some of their characteristics. The demons Vassago, Seir, Dantalion and Andromalius are not listed in this book. Pseudomonarchia Daemonum does not attribute seals to the demons, as The Lesser Key of Solomon does.
Weyer said to have been inspired by another grimoire also attributed to King Solomon.
