It is International Cat Day. That should lead to an abundance of cute cat movies, but we will mark the occasion by sharing a work by Escher. He depicted several cats (and catlike animals) in his linocuts and woodcuts, mainly in his younger years. Sometimes as a subject, sometimes as a detail.
Like in this woodcut of the Corsican mountain town Corte. Escher visited the island in the spring of 1928, with his father-in-law. Jetta stayed at home; she was pregnant with their second child. From atop a wall a white cat looks into an alley of the seemingly deserted town. Its presence is subtle, yet forceful.
