Alpha et Omega
The Alpha et Omega was an occult order, initially named the Hermetic Order of the Golden Dawn, co-founded in London, England by Samuel Liddell MacGregor Mathers in 1888. The Alpha et Omega was one of four daughter organisations into which the Hermetic Order of the Golden Dawn fragmented, the others being the Stella Matutina; the Isis-Urania Temple led by A. E. Waite and others; and Aleister Crowley's A∴A∴.
