The Lesser Key of Solomon, also known by its Latin title Lemegeton Clavicula Salomonis or simply the Lemegeton, is an anonymously authored grimoire on sorcery, mysticism, and magic. It was compiled in the mid-17th century from materials several centuries older. It is divided into five books: the Ars Goetia, Ars Theurgia-Goetia, Ars Paulina, Ars Almadel, and Ars Notoria. It is based on the Testament of Solomon and the ring mentioned within it that he used to seal demons.
