The Key of Solomon the King: Clavicula Salomonis is the classic grimoire, or book of magic, incorrectly attributed to the ancient King Solomon who reigned over Israel during the 9th century B.C. The work likely dates back to the 14th or 15th century Italian Renaissance and is a typical work of Renaissance magic. Detailed within this volume are many examples of ritualistic magic typical to the ancient world. Presented here in this volume is the English translation of the famous modern occultist S. L. MacGregor Mathers based on an edition of the Latin manuscripts of the British Library as edited by L. W. de Laurence in his 1914 publication.
