Johan Weyer’s Pseudomonarchia Dæmonum first appeared as an appendix to his 1563 work, De Praestigiis Dæmonum. This infamous catalogue of Demons and Devils is a classic of Demonology whose influence on the literature of grimoires and black magic cannot be understated. Presented here in this quaint edition is Reginald Scot’s 1583 English translation.
