The Grimoire of Honorius

The Grimoire of Honorius is a controversial ceremonial magic text falsely attributed to Pope Honorius III and associated with later medieval and early modern magical practice. It is notable as a specimen of learned Latin ritual magic, containing conjurations, prayers, and instructions that blend Christian language with magical operations.

Works attributed to Pope Honorius III often belong to the tradition of medieval ritual magic rather than to the historical pope himself. In esoteric literature, the name is associated with grimoiric texts circulated under papal authority, though the attributions are generally regarded as pseudepigraphic.
