M.C. Escher, Self-Portrait in a Chair, woodcut, February 1920
Seen from the viewer’s perspective, the zigzagging of the legs runs all the way up to Escher’s right elbow. Via his shoulder and eyes, our eyes are directed to the other side and into the top-left corner. Finally our gaze returns to the bright eyes and we see the prominent art behind Escher’s head. Escher is making a clear statement: I am an artist, these are my surroundings, I am the master of my craft and I have my own (unorthodox) vision.
