The Sworn Book of Honorius Liber

Nature and Significance:
- The Sworn Book of Honorius (Liber Iuratus Honorii) is recognized as one of the oldest and most important grimoires of medieval magic.
- It represents a "magic religion" or theurgical system that is highly religious but often at odds with established church authorities.
- It acts as a crossroads for Christian, Jewish, and Arab esoteric teachings.
- History refers to it second only to the writings of Solomon in notoriety during the medieval period.
Historical Timeline and Mentions:
- circa $1230$ : Likely mentioned and condemned by William of Auvergne.
- $1347$ : Described in the trial of Olivier Pépin in Mende, France.
- $1376$ : Referenced in Eymerich’s Directorium inquisitorum.
- $1398$ : Likely included in condemnations by the Faculty of Theology at the University of Paris.
- $1582$ : Referenced in the secret mystical diaries of John Dee.
Title and Origins:
- Named the "Sworn Book" because owners were bound by a severe oath to secrecy, often requiring the book to be buried with them in their grave.
- Latin titles include Liber sacer sive iuratus ("The Sacred or Sworn Book") and Liber sacratus ("The Consecrated Book").
- The legendary author is Honorius of Thebes, described as the son of Euclid. Thebes (Greece) was historically a crossroads for Jewish populations and Eastern/Western Christian turmoil.

Integrative Framework: Unlike many grimoires which are collections of unrelated spells, the Liber Iuratus is a coherent system of magical attainment based on medieval science and theology.
The Five Treatises (Books):
- Book I: Preparation of the Sigillum Dei (Seal of God) and the methods for achieving the Beatific Vision (seeing God face to face).
- Book II: Knowledge regarding the Heavens and the natures, names, and offices of planetary angels.
- Book III: Spirits of the Air, including methods for raising winds and constructing circles for invocation.
- Book IV: Spirits of the Earth (terrestrial and infernal spirits), focusing on identifying hidden treasures and releasing prisoners.
- Book V: General exposition, including instructions for magical tools (ink, whistle, wand).

The Centerpiece: The ritual to attain the "Beatific Vision" is the primary goal, allowing the operator to see the divine essence while still alive.
Parallels: This concept mirrors Jewish Merkabah mysticism (the heavenly throne) and the devequt (conjunction with God).
Pre-requisites:
- Absolute physical and spiritual purity.
- A $72$ -day ritual process (shortened to $40$ days in some versions like Ganell’s Summa).
- Fasting on bread and water, sexual abstinence, and constant prayer.
- Strategic use of masses and liturgical hours.

Purpose: A central component used to control all spirits (celestial, aerial, terrestrial, and infernal).
Construction Details:
- Drawn on virgin parchment from a calf, foal, or deer.
- Written using blood from a mole, turtledove, hoopoe, or bat.
- Consists of a complex arrangement of circles, pentagons, and heptagons.
The Shem Ha-Meforash:
- Contains the $72$ -letter name of God derived as an acronym/subset of a list of $100$ holy names.
- The acronym is often divided into eight groups of nine letters: Toexoraba, Layqtiyst, Algaonosu, Laryceksp, Fyomemana, Renugarel, Atedatono, Naoyleyot.
Protective Virtues: It is said to protect against ghosts, physical danger, and provide victory in all endeavors.

The Magic Circle: A "map of the universe" used for fortification against spirits. It is usually $9$ feet in diameter. In Earth magic, a deeper, hollow circle is used for Spirit thrones.

The Wand: Must be made of laurel or hazel from the current year. It must be four-sided with the names Adonay, Sabaoth, Hiskiros, and Emanuel written on it.
The Whistle: Used only for aerial and terrestrial spirits (not for good angels). Can be made of gold, silver, copper, or hazel. It is heptagonal ( $7$ -sided) and engraved with the names of the seven kings.
The Swords: Seven polished swords of equal length are required for calling forth spirits.
Ink: Specially consecrated blood used to write the Seal. The text provides a specific "Exorcism of the Blood" adapted from the blessing of salt.
