The Blue Equinox, officially known as The Equinox: Volume III, Number I, is a book written by the English occultist Aleister Crowley, the founder of Thelema. First published in 1919, it details the principles and aims of the secret society O.T.O. and its ally the A∴A∴, both of which were under Crowley's control at the time. It includes such topics as The Law of Liberty, The Gnostic Mass, and Crowley's "Hymn to Pan". Background In 1904, Crowley was staying in Cairo, Egypt with his wife Rose when he claimed to undergo a spiritual experience. Synopsis The Blue Equinox opens with Crowley's poem "Hymn to Pan", a devotional work devoted to the ancient Greek deity Pan. This is followed by an editorial, in which Crowley discusses Thelema, the A∴A∴ and the O.T.O., and the important role which he believed that they had to play in the Aeon of Horus.
