One of Escher's best-known images, this lithograph of two hands drawing each other presents several of the artist's favorite concepts. Most notably, it is an example of what author Douglas Hofstadter has called a 'strange loop,' a paradoxical system which continuously self-referentially repeats with no seeming beginning or end. Escher was fascinated by such paradoxical recursions, whether he explored them in the form of staircases, waterfalls, or self-illustrating hands. This is also one of Escher's clearest explorations of the illusionism implicit in representational art, as the line between two-dimensional drawing and three-dimensional reality are cleverly at play.
