Oliver St. John is the author of twelve books covering Hermetic and Thelemic philosophy, Qabalah, operative magical Theurgy, the Tarot and astrology. He received initial training through a five-year course in Applied Qabalah written by Gareth Knight and W. E. Butler. In 1996 e.v., he forged a magical link with the Law of Thelema, the ancient Egyptian “93” current that was unearthed through the mediumship of Aleister and Rose Crowley. This led to his foundation of the Hermetic college Ordo Astri in 2000 e.v., and his entry into Kenneth Grant’s Typhonian Order (formerly Typhonian OTO) in the same year. Over the course of time, Oliver St. John has worked with Mary Long (author and student of Dion Fortune), Gareth Knight, Dolores Ashcroft-Nowicki (co-founder of the Servants of the Light Association) and Olivia Robertson (co-founder of the Fellowship of Isis).
