Book excerpt: This fascinating work explores John Dee's Enochian magic and the history of its reception. Dee (1527–1608/9), an accomplished natural philosopher and member of Queen Elizabeth I's court, was also an esoteric researcher whose diaries detail years of conversations with angels achieved with the aid of crystal-gazer Edward Kelley. His Enochian magic offers a method for contacting angels and demons based on secrets found in the apocryphal Book of Enoch. Examining this magical system from its Renaissance origins to present day occultism, Egil Asprem shows how the reception of Dee's magic is replete with struggles to construct and negotiate authoritative interpretational frameworks for doing magic. Arguing with Angels offers a novel, nuanced approach to questions about how ritual magic has survived the advent of modernity and demonstrates the ways in which modern culture has recreated magical discourse.
