Johann Weyer and the 1577 Pseudomonarchia Appendix

Pseudomonarchia Daemonum is associated with Johann Weyer, but its first printed setting was a later edition of his larger book. The two publication dates describe different objects.

Author: Johann Weyer (1515–1588)
First De praestigiis: 1563
Appendix witness: Fifth edition, 1577

The larger work came first

Weyer issued De praestigiis daemonum in 1563. The surviving edition record identifies a substantial Latin book about demons, enchantments, and witchcraft. A reader searching for the beginnings of Weyer’s argument should start there. The 1563 publication date belongs to the larger work; it should not be used as the publication date of every component later appended to it. Edition history matters because titles and catalog summaries often compress years of revision into a single familiar name.

Weyer was a physician working in an era of witch trials and demonological controversy. His text challenged the certainty with which accusations and supposed evidence of witchcraft were treated. That position does not turn every sentence into modern skepticism. His theological and medical assumptions belonged to the sixteenth century. Describing him as either a modern scientist or a writer of an endorsed conjuring handbook flattens the book into a role it did not have.

What the 1577 title page establishes

Indiana University catalogues a 1577 Basel printing as the fifth, expanded and revised edition of De praestigiis daemonum. Its long title expressly names both Liber apologeticus and Pseudomonarchia daemonum as additions. The digitized 1577 volume lets readers inspect the printed witness itself. This is stronger evidence for the appendix than citing a modern retelling that simply says Weyer published a demon list in 1563.

The title Pseudomonarchia suggests a false or counterfeit monarchy. Its list of ranked spirits was printed inside a book whose author questioned the claims of magicians and witch accusers. Reading the catalogue in that setting changes the question: it is evidence about a printed polemic and the older material Weyer chose to expose, abbreviate, and criticize. A listing of reported powers remains a claim inside a historical text, not an independently verified property of any spirit.

Worked comparison: Pruflas disappears between Weyer and Scot

Weyer’s 1577 list places Pruflas, also transmitted as Bufas, fourth. The entry follows the catalogue’s compact internal grammar: it gives a mixed rank of prince and duke, locates the spirit around the Tower of Babylon, describes a fiery or night-raven manifestation, assigns discord, war, quarrels, and deception as offices, then closes with responses and twenty-six legions. Rank, appearance, office, behavior, and command count make one structured record. The Wellcome Collection’s 1583 sixth edition shows that the appendix continued in print, but the later date does not erase the wording and position preserved by the fifth edition.

Scot’s 1584 English catalogue omits Pruflas. The later Ars Goetia also lacks that entry, so its sequence moves from Vassago to Samigina without a fourth-position counterpart to Weyer’s Pruflas. This is more consequential than reducing a total by one: the deletion changes which entries are neighbors and shifts every comparison based only on list number. It also demonstrates why the Weyer, Scot, and Goetia catalogues cannot be treated as interchangeable copies. A worked alignment must compare the name, position, office, and surrounding entries before deciding whether two records represent the same transmitted item.
