The Grimoire of Pope Honorius, or Le Grimoire du Pape Honorius, is an 17th to 19th century grimoire, claiming to be written by Pope Honorius III (1150 -1227). It is unique among grimoires in that it was specifically designed to be used by a priest, and some of the instructions include saying a Mass. While its name is derived from the 13th century Grimoire of Honorius, its content is closer to later grimories like the Key of Solomon and Grimorium Verum. Edited and translated into English by Edmund Kelly The Grimoire of Pope Honorius Is a book that holds its place in occult literature.
