The sequel to Aegypt is Love & Sleep (see separate entry). The second novel in Crowley's tetralogy employs many of the same characters as Aegypt and continues to develop the themes of time and memory that occupy Crowley in Aegypt. Love & Sleep carries forward the main plot lines: the search for the world's secret history and the struggle of Pierce Moffett for personal happiness. The two novels are complimentary, Aegypt focusing on Moffett's recent disappointments while Love & Sleep presenting key experiences from his youth; they enrich each other, but can stand alone. This pairing of the individual's search for fulfillment with a mysterious plan of grand scope that exceeds understanding is also central to Crowley's fantasy novel, Little, Big.

In addition, Crowley's short sstory collection, Novelty, focuses on history and myth, time and memory.
