The impossible cube or irrational cube is an impossible object invented by M.C. Escher for his 1958 print Belvedere. It is a two-dimensional figure that superficially resembles a perspective drawing of a three-dimensional cube, with its features drawn inconsistently from the way they would appear in an actual cube.
