Anon 2001: "The Golden Dawn ceased to exist by that name after October 1901, replaced by Mathers's Alpha et Omega and the London group’s Order of the Morgan Rothe. No longer associated with the SRIA after 1902, Mathers continued to oversee a few temples until his death, when his wife, Moina, assumed supervision." Anon (February 26, 2001).
