We recently added to our catalogue Escher & schatten uit de islam, a catalogue of an exhibition held a few years ago at the Escher in Het Paleis museum in The Hague. This demonstrates well the influence of Islamic art on M.C. Escher. He was undoubtedly inspired by two visits he made in 1922 and 1936 to the Alhambra, the palace complex built at Granada by Spain’s last Muslim rulers. The images below show detailed sketches he made during his trips. Escher was not the first person to be impressed by the wonders of the Alhambra; this post looks at some earlier travellers to the fortress and their related work.
