The first book of The Lesser Key of Solomon, concerning the 72 Demons which King Solomon bound with in a brass vessel.  This grimoire contains descriptions of the Demons and their seals, as well as all rituals and requisites required for their summoning.

The Lesser Key of Solomon, also known as Clavicula Salomonis Regis or Lemegeton, is an anonymous grimoire (or spell book) on demonology. Its one-hundred-forty-four spells were compiled in the mid-17th century, mostly from materials some centuries older. It is divided into five books—the Ars Goetia, Ars Theurgia-Goetia, Ars Paulina, Ars Almadel, and Ars Notoria.
