The Cult of the Black Cube: A Saturnian Grimoire by Dr. Arthur Moros (a pseudonym) is an esoteric work that explores the "Saturnine current"—a, dark, antinomian (anti-cosmic) magical path centered on the deity Saturn. Described as both a scholarly study and a practical grimoire, the book examines the historical and modern occult significance of Saturn as a force of "Dark Gnosis". The book cautions that this path deals with intense and potentially dangerous energies, recommending it for mature practitioners.
