I have long had this war within me. Therefore, it does not concern me internally. To work my way out of my ruins, I had to fly. And I flew. In that shattered world, I only linger in memory, as one sometimes reflects back. (Paul Klee, 1915) The artistic work presented here in forty selected paintings and watercolors is an expression of an unusual sensitivity and intellectual depth that transformed Paul Klee's fragile creations into valid and timeless messages. In his introductory text, art historian Johann Konrad Eberlein traces the artistic and biographical milestones of Paul Klee.
