M.C. Escher is one of the great conundrums of modern art. He is an artist whose work is as instantly recognizable as anything by Salvador Dalí, yet his name means little to a British audience. Escher was never affiliated to any group, rarely travelling far from his modest home in the Dutch town of Baarn, and focusing exclusively on graphic art. He was a one-man art movement who created some of the most famous and popular images in modern art, yet he remains a complete enigma.
