Anna Sprengel (アンナ=シュプレンゲル An'na Shupurengeru?) is a woman who was said to have helped found the Golden Dawn and supposedly carried out the role of Secret Chief, though her existence is a dubious one.[1]


In the past, Anna supposedly helped in the foundation of the Golden Dawn. She is said to have had the role of Secret Chief, and functioned as a point of contact, much like Aleister Crowley would act as a point of contact for Aiwass, described by him as one of the theories concerning the Secret Chief. However, it isn't certain whether she actually existed or whether her existence was fabricated.[1] A letter which William Wynn Westcott supposed received from her was actually forged by him in order to give prestige to the cabal he helped found.[2][3] Wanting to claim that the cabal was the continuation of an ancient Rosicrucian line, he faked a letter sent to a German cabal (whom he claimed to have two temples) as well as a response from Anna Sprengel authorizing the creation of a British branch (hence the Isis-Urania Temple being called #3), an exchange known as the Sprengel Letters.[4]

At some point during the time of the Golden Dawn, a fraud known as Madame Horos posed as Anna Sprengel, bringing a disaster to the cabal and earning the hatred of Samuel Liddell MacGregor Mathers.[5]

Anna Sprengel was mentioned during Aleister Crowley's explanation concerning the Isis-Urania Temple during the events involving the reproduced Golden Dawn.[4] The events concerning the Horos deception were also referenced.[5]


According to Aleister Crowley, Anna was said to have been the same higher existence that he became, existing in a different dimension, beyond just being expressible as 0 or 1, and being able to exist in multiple locations at the same time.[1]
