The Equinox (subtitle: The Review of Scientific Illuminism) was a periodical that served as the official organ of the A∴A∴, a magical order founded by Aleister Crowley (although material is often of import to its sister organization, Ordo Templi Orientis). Begun in 1909, it mainly featured articles about occultism and magick, while several issues also contained poetry, fiction, plays, artwork, and biographies. The last issue was published in 1998.
