On my left the shooting had the sharp explosion of the infantry artillery, on my right could be heard the sporadic cannon shots thundering from the front, and up above the sky was clear and the sun bright.
I think only of objects: of a leg or an arm, of the wonderful sense of foreshortening, breaking through the plane, of the division of space, of the combination of straight lines in relation to curved ones.
Height, width, and depth are the three phenomena which I must transfer into one plane to form the abstract surface of the picture, and thus to protect myself from the infinity of space.
What are you? What am I? Those are the questions that constantly persecute and torment me and perhaps also play some part in my art.
