Crowley states that he and Victor Benjamin Neuburg evoked Choronzon in Bousaada, Algeria in December 1909. In Crowley's account, it is unclear whether Choronzon was evoked into an empty Solomonic triangle while Crowley sat elsewhere, or whether Crowley himself was the medium into which the demon was invoked. Nearly all writers except Lawrence Sutin take him to mean the latter. In the account, Choronzon is described as changing shape, which is read variably as an account of an actual metamorphosis, a subjective impression of Neuburg's, or fabrication on Crowley's part.
