The Equinox (subtitle: "The Review of Scientific Illuminism") is a series of publications in book form that serves as the official organ of the A.'.A.'., the mystical order of Aleister Crowley (although material is often of import to its sister organization, Ordo Templi Orientis). Begun in 1909, it remains one of the definitive works on occultism and magick, while several issues also contain poetry, fiction, plays, artwork, and biographies. The last issue was published in 1998.<!-- Deleted image removed: -->
