Cubism was an early 20th century avant-garde art movement that revolutionized European painting and sculpture. Inspired by developments in science and technology, as well as non-Western art, Cubism depicted subjects from multiple perspectives to represent four-dimensional reality on a two-dimensional surface. Pioneered by Pablo Picasso and Georges Braque, Cubist works featured geometric shapes and abstracted forms rather than realistic renderings. Other notable Cubists included Fernand Léger, Juan Gris, and Jean Metzinger. Cubism opened the door for later abstract art movements and changed the course of modern visual art.
