“The volume is dedicated to the memory of Nicholas Goodricke-Clarke, a leading scholar of esotericism, and contains a Foreword about him written by Joscelyn Godwin. The volume transcends the boundaries of historical periodization and successfully introduces the notion of ‘innovation’ to the scholarship of esotericism.” (Mriganka Mukhopadhyay, Religious Studies Review, Vol. 49 (1), March, 2023)
