Hermetic Order of the Golden Dawn
The Isis-Urania Temple was initially the first temple of the Hermetic Order of the Golden Dawn. The three founders, Dr. William Robert Woodman, William Wynn Westcott, and Samuel Liddell MacGregor Mathers, were Freemasons and members of Societas Rosicruciana in Anglia (S.R.I.A.). It continued as one of four daughter organisations into which the Hermetic Order of the Golden Dawn fragmented, the others being the Alpha et Omega, the Stella Matutina and Aleister Crowley's A∴A∴.
