Antoine Faivre delivers a historical and symbolic analysis of engravings illustrating the work of Jacob Boehme (1575-1624), the ‘Theosophist of Amsterdam” published by Goerg Gichtel. As well as revealing their author (only identified in 2007), the author furnishes an accurate definition of what he means by “Theosophy” and also reviews the subsequent hermetic currents of 17th century Germany it gave birth to.
