The Thelemic Symposium was cooked up by a couple of hung-over Thelemites back in 1986. It is hosted by the Oxford Golden Dawn Occult Society, which is a non-sectarian magical sodality that shelters within its ranks magicians of many diverse kinds. The symposium is an annual event that brings together magicians working within the thelemic tradition on topics and themes of interest to thelemic and other left hand path magicians. The printed talks in this volume give a useful snapshot of what these interests are. There is an essay on Aleister Crowley, the founder and continuing inspiration to the movement. This was written by an influential playwright Snoo Wilson and broadcast on Channel Four television last year. There are also talks on the magical work that occupies the modern magician -- Invocation of the Holy Guardian Angel, the Cult of LAM, Enochia, Chaos Magick, Devotion to Babalon and the sorcery of Austin Osman Spare.
