Zurich, 1944: Carl Gustav Jung published "Psychology and Alchemy" in which he explores strong connections between the symbolic of individual  dreams and medieval Alchemy.  I like this book so much because since my childhood I always appreciated books where interesting texts were juxtaposed with interesting images. For example, Gustave Doré's "Bible", with more then 200 engravings, is the most exciting "Bible" I have ever seen. And "Psychology and Alchemy" is a combination of extremely interesting Jung's theory and, for me always inspirited, authentic alchemic iconography.
