Aleister Crowley, with the assistance of J. F. C. Fuller, serialized an extensive magical autobiography based in part on the record of his personal diary, as Frater Perdurabo or Fra. P, in the pages of The Equinox. This serialized article was called “The Temple of Solomon the King” and details Crowley’s experience up to and including achieving the grade Magister Templi, or Master of the Temple. Included during this period of time was the Equinox of the Gods, which began with the reception of the Book of the Law on April 8, 9 & 10, 1904.
The publication of the rituals of the Hermetic Order of the Golden Dawn in The Equinox as part of The Temple of Solomon the King resulted in a famous trial. You can read about this trial in several articles and letters that appeared in the press of the time.
