In 1563, Johann Weyer authored De Praestigiis Daemonum et Incantationibus ac Venificiis (in English: On the Illusions of the Demons and on Spells and Poisons), a point-by-point rebuttal of the Malleus Maleficarum. It included an appendix called the Pseudomonarchia Daemonum (in English: The False Kingdom of the Demons) describing the hierarchy of demons in Hell.
The Lesser Key of Solomon, despite its mysterious accreditation, is generally understood to have used this text as a basis for its own list of demons.
