The Grimoire of Pope Honorius

While its name might be derived from the 13th century grimoire The Sworn Book of Honorius, its content is closer to later grimories like the Key of Solomon and Grimorium Verum.

The first edition of the Grimoire is said to have appeared in 1629, and was likely forged near the end of the sixteenth century, roughly four hundred years after the death of its supposed author.

"[1] According to Éliphas Lévi, "Some old copies of the Grimoire of Honorius bear, however, the name of Honorius II, but it is impossible to make a sorcerer of that elegant Cardinal Lambert (...) But it so happens that the name of Honorius II is for us as a ray of light pointing to the true author of the frightful grimoire in question (...) In 1061, the bishops of Lombardy, impelled by Gilbert of Parma, protested against the election of Anselm, Bishop of Lucca, who had been raised to the papal chair as Alexander II.

They chose Cadulus or Cadalus, an intriguing Bishop of Parma, a man capable of all crimes and a public scandal in respect of simony and concubinage.

Cadalus returned into obscurity and it is then probably that he decided to become the high priest of sorcerers and apostates, in which capacity, and under the name of Honorius II, he composed the Grimoire that passes under this name.
