Also known as the Lemegeton, The Lesser Key of Solomon is a foundational grimoire of demonology, cataloguing the names, attributes, seals, and conjurations of 72 spirits said to have been summoned and commanded by King Solomon. Focusing primarily on the Goetia, the first and most renowned section of the text, this work offers detailed instructions for invoking demons, along with the rituals, protections, and ceremonial tools required to engage with them safely and purposefully. The Lesser Key of Solomon presents a structured and disciplined spiritual system rooted in Solomonic, Kabbalistic, and Renaissance magical traditions. S. Liddell MacGregor Mathers' translation, edited and introduced by Aleister Crowley in 1904, brings together centuries of preserved manuscripts with scholarly commentary and occult insight.
