The Lesser Key of Solomon

The Lesser Key of Solomon, also known as Lemegeton Clavicula Salomonis or simply Lemegeton, is an anonymous grimoire on demonology. It was compiled in the mid-17th century, mostly from materials a couple of centuries older. It is divided into five books-the Ars Goetia, Ars Theurgia-Goetia, Ars Paulina, Ars Almadel, and Ars Notoria. This edition was translated by Samuel Liddell MacGregor Mathers and published by Aleister Crowley under the title The Book of the Goetia of Solomon the King. Crowley added some additional invocations previously unrelated to the original work, as well as essays describing the rituals as psychological exploration instead of demon summoning.
