Dragon, wood engraving, 1952.

“No matter how hard this dragon tries to appear spatial, it remains a flat image. Two incisions are made in the paper on which it is printed. It is then folded in such a way that two square holes are created. But it is a idiosyncratic animal, this dragon, and despite its two dimensions, it insists it has three. That’s why it puts its head through one hole and its tail through the other.” ~ M.C. Escher, Grafiek en Tekeningen.
