"Out of the mist of the beginning of our era there looms a pageant of mythical figures whose vast, superhuman contours might people the walls and ceiling of another Sistine Chapel. " (H. Jonas) The purpose of this book is to show how far a philosophical cross-elucidation of Alchemy, Freemasonry and Jungian Analysis is possible. Amongst its conclusions are the following theses : Philosophy is, in its core, ascetic and gnostic ; Alchemy does not have much to do with gold but with the quest toward transfiguration ; Freemasonry has built upon this philosophico-alchemical legacy ; Jungian Analysis fosters, in a more mundane context, this very same ideal.
