Within the system of Thelema, history is broken down into a series of Aeons, each with its own dominant concept of divinity and its own "formula" of redemption and advancement. According to Aleister Crowley, the last three Aeons have been (1) the Aeon of Isis, (2) the Aeon of Osiris, and (3) the current Aeon of Horus which began in 1904 with the writing of The Book of the Law.
