The Penrose triangle, also known as the tribar is an impossible object. It was first created by the Swedish artist Oscar ReutersvÃ¤rd in 1934. The mathematician Roger Penrose independently invented and popularised it in the 1950s, describing it as "impossibility in its purest form". It features prominently in the works of artist M. C. Escher, whose earlier depictions of impossible objects partly inspired it.
