The Sworn Book of Honorius

The Sworn Book is supposedly the product of a conference of magicians who decided to condense all of their knowledge into one volume.

In 93 chapters, it covers a large variety of topics, from how to save one's soul from purgatory to catching thieves or finding treasures.

It has many instructions on how to conjure and command demons, to work other magical operations and knowledge of what lies in Heaven among other highly sought information.

[2] The Sworn Book features the Seal of Solomon and contains ritual elements which are characteristic of the Pseudo-Solomonic corpus of magical literature.

Honorius of Thebes is also claimed to be the creator of the Theban alphabet, in Heinrich Cornelius Agrippa's De Occulta Philosophia (1533) and Johannes Trithemius's Polygraphia (1518).
