Illustrated plate from The Lesser Key of Solomon, Goetia, the Book of Evil Spirits, edited by L. W. de Laurence (Chicago: de Laurence, Scott & Co., 1916). View digitized edition at Project Gutenberg.
Also called the Lemegeton, the Lesser Key is distinct from the Key of Solomon, although both invoke the same legendary author. Its component sections circulated within evolving manuscript traditions. Modern editions have made the Ars Goetia particularly famous, but the larger compilation and its textual variants provide a fuller historical picture.
