(Summer Clouds)"I had an infinite number of visions at this time, for wherever I turned my eyes nature, the sky, the clouds were alive, in each stone and in the branches of each tree, everywhere, my figures stirred and lived their still or wildly animated life, and they aroused my enthusiasm as well as tormented me with demands that I paint them." ~Emil Nolde
