The Blue Equinox

Book by Aleister Crowley

The Blue Equinox, officially known as The Equinox (Volume III, Number 1) 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".

In February 1904, Aleister Crowley and his wife Rose arrived in Cairo. Pretending to be a prince and princess, they rented an apartment in which Crowley set up a temple room and began invoking ancient Egyptian deities, while studying Islamic mysticism and Arabic. According to Crowley's later account, Rose regularly became delirious and informed him "they are waiting for you." On 18 March, she explained that "they" were the god Horus, and on 20 March proclaimed that "the Equinox of the Gods has come". She led him to a nearby museum, where she showed him a seventh century BCE mortuary stele known as the Stele of Ankh ef en Khonsu; Crowley thought it important that the exhibit's number was 666, the Number of the Beast in Christian belief, and in later years termed the artefact the "Stele of Revealing." According to Crowley's later statements, on 8 April he heard a disembodied voice identifying itself as that of Aiwass, the messenger of Horus, or Hoor Paar Kraat. Crowley said that he wrote down everything the voice told him over the course of the next three days, and titled it Liber AL vel Legis or The Book of the Law. The book proclaimed that humanity was entering a new Aeon, and that Crowley would serve as its prophet. It stated that a supreme moral law was to be introduced in this Aeon, "Do what thou wilt shall be the whole of the Law," and that people should learn to live in tune with their Will. This book, and the philosophy that it espoused, became the cornerstone of Crowley's religion, Thelema. In 1909, Crowley initiated publication of an irregular journal of Thelema, The Equinox. It served as the "official organ of the A∴A∴", his teaching order, and of Ordo Templi Orientis, his social order. It mainly featured articles about occultism and magick, while several issues also contained poetry, fiction, plays, artwork, and biographies. The Blue Equinox is the first issue of the third volume of the journal.
