Geosophia traces the development of magic from the Greeks to the grimoires, laying bare the chthonic roots of goetic ritual. By exposing the necromantic origins of much of modern magic we are able to reconnect with the source of our ritual tradition. There is a continuity of practice in the West which encompasses the pre-Olympian cults of Dionysus and Cybele, is found in the Greek Magical Papyri and Picatrix and flows into the grimoires. Rather than a muddle of superstition, the grimoire tradition is revealed as the living descendant of the ancient practices of the Goes. This is a work which redefines our understanding of the Western tradition, one which does not begin with Cabbala or Solomon, but rather descends into the Underworld and brings forth new life. The author illuminates scarce and overlooked texts with an incisive commentary, from volcanic conjurations to over 70 pages dealing with Picatrix.
