This issue of THE EQUINOX features Liber 418, THE VISION AND THE VOICE, and is the record of Crowley's visionary exploration of the 30 Aethyrs of the Enochian system of magick developed by the Elizabethan magicians Dr. John Dee and Edward Kelley. Most were received in the Sahara Desert in 1909, with the assistance of Victor B. Neuburg. This text is the source of many of the spiritual doctrines of Thelema, including much of its theogony, particularly concerning the All-Father Chaos and the goddess Babalon. Other works and papers give details of Crowley's advanced initiations. Liber 415, Opus Lutetianum (The Paris Working), is the record of a magical working. It includes the Esoteric Records of the Paris Working as well as the Holy Hymns to the Great Gods of Heaven. The surviving portion of Liber 73, the Urn (Diary, of Magus), and The Book of the Great Auk, are included, as well as The Fox of the Balkans.
