Grimoire

A grimoire (from Old French grammaire, meaning "grammar") is a textbook of magic, typically including instructions on how to perform magical disciplines, the preparation of talismans and magical tools, and the invocation of spirits. The term is often used interchangeably with the word "spellbook," though the former is typically applied to works of a more formal, structured, and extensive nature. In Hebrew, a grimoire may be referred to as ספר קסמים (Sefer Kesamim), literally meaning "book of spells." In Latin, the term grimorium is used, while in German, it is known as Zauberbuch, meaning "magic book." Grimoires have been found in various cultures and historical periods, with some of the most famous examples including the Key of Solomon, the Lesser Key of Solomon (or Lemegeton), and the Picatrix. These texts often contain a mix of magical theory, ritual instructions, and lists of supernatural entities that can be summoned or controlled. The study and use of grimoires have been a subject of interest in both occult practices and academic research, particularly in the fields of religious studies and the history of magic.
