Cubism is when you represent an object through art, but instead of representing it through an individual's one-dimensional perspective you represent it through multi-dimensional perspectives or a multitude of view points. Pablo Picasso was one of the most famous cubists, but other famous cubists are Paul Cezanne and Fernand Leger. Cubism has been widely regarded as one of the most influential art movements in the 20th century and cubism also inspired literature, music and architecture.
