A magical grimoire of sigils and rituals for summoning and mastering spirits, The Key of Solomon the King is the most infamous, of all magick books. It has influenced everything from the revival of magick and the Western Mystery Traditions (tarot, alchemy, astrology, etc.) to fictional works such as Lovecraft's The Necronomicon. This new 2017 edition of S. L. MacGregor Mathers' masterwork includes reproductions of all original 13 plates from the 1885 edition.
