Pseudomonarchia Daemonum was created in 1577.

Johann Weyer, aka Wierus, Wier (1515-1588) was a German physician, occultist and demonologist, disciple and follower of Heinrich Cornelius Agrippa. He wrote the books De Praestigiis Daemonum (1563) and twenty years later Pseudomonarchia Daemonum (1583) as an appendix to the first. AU

De praestigiis daemonum was created in 1563.

I would have to say no. Johann Weyer printed it as a direct response to the handbook, Malleus Maleficarum, which was an anti witch/occult guide book. The original title of this particular heirarchy was, Pseudomonarchia Daemonum (The false monarchy of the demons). Therefore, I would assume that it is not viable as a true statement of the heirarchy.
