Magical Treatise of Solomon
The Magical Treatise of Solomon, also known as the Hygromanteia (Greek: Ὑγρομαντεία) or Solomonikê (Greek: Σολομωνική), is a collection of late Byzantine grimoires. A pseudepigraphon, the book was written in medieval Greek and purports to contain Solomon's instructions to his son Rehoboam on various magical techniques and tools.
