This collection explores the role of innovation in understanding the history of esotericism. It illustrates how innovation is a mechanism of negotiation whereby an idea is either produced against, or adapted from, an older set of concepts in order to respond to a present context. Featuring contributions from distinguished scholars of esotericism, it covers many different fields and themes including magic, alchemy, Rosicrucianism, Theosophy, Tarot, apocalypticism and eschatology, Mesmerism, occultism, prophecy, and mysticism.
