The Equinox, also called The Review of Scientific Illuminism, has become the standard for English language esotericism, aptly termed the "Encyclopedia of Initiation" by its principal editor and contributor, Aleister Crowley. The remarkable variety, depth, and utility of its contents encompass Qabalah, tarot, yoga, and the essential papers of Crowley's teaching order, A. A. The new edition is supplemented by Crowley's serialized biography along with excerpts from his many diaries, an overview of the Golden Dawn System, a book-length special section of the Qabalistic dictionary Sepher Sephiroth, fiction, poetry, book reviews, and extracts from The Vision and the Voice and The Rites of Eleusis as well as important works by other noted authors such as The Key of the Mysteries by Eliphas Levi. Crowley's extensive annotations from his personal copies have been collected at the end of the set, along with biographies of the contributors. Begun in 1909, it remains one of the definitive works on occultism and magik.
Aleister Crowley (1875-1947) combined scholarly rigor with a sense of humor and great literary ability to become the most widely read author in 20th-century occultism. He single-handedly redefined magick as a field of inquiry and endeavor through his books and the orders that he led--the A.A. and the O.T.O. In the 2002 BBC Great Britons poll in which over one million people voted, Crowley ranked 73 among the hundred most influential Britons of all time.
