Johann Weyer, whose 1577 Pseudomonarchia Daemonum is the direct ancestor of the ranked catalogue used in the later Lemegeton, compiled his list as part of a broader argument against the witch persecutions of his own time, holding that those accused of consorting with demons were more often deluded or mentally ill than genuinely guilty of the crimes charged against them. The elaborate hierarchy of named, ranked spirits he catalogued was meant, in that original context, to satirise and undercut inflated claims about demonic power rather than to hand practitioners a working manual for invoking it. Later readers largely inverted that purpose, stripping away Weyer's sceptical framing and reprinting his catalogue, and the derived Goetia that grew from it, as straightforward magical reference works.
Some manuscripts of the Lemegeton also assign four of the ranked Kings specifically to the cardinal points of the compass, generally given as Amaymon in the east, Corson in the south, Ziminiar in the north and Paimon in the west, an internal geography layered onto the catalogue that has no equivalent for the Duke, Prince or other lower ranks, which are differentiated by the number of legions each spirit commands rather than by any directional assignment.
