"The woodcut is the most graphic of the printmaking techniques. Its practice demands much technical ability and interest. Kirchner's technical skill made woodcutting easy for him. Thus he came in a spontaneous way through the simplification necessary here to a clear style of representation. We see in his woodcuts, which constantly accompanied his creative work, the formal language of the paintings prefigured."
