Originally a term of derision used by a critic in 1908, Cubism describes the work of Pablo Picasso, Georges Braque, and those influenced by them. Working side by side, they developed a visual language whose geometric planes and compressed space challenged what had been the defining conventions of representation in Western painting: the relationship between solid and void, figure and ground. Traditional subjects—nudes, landscapes, and still lifes—were reinvented as increasingly fragmented compositions. Cubism’s influence extended to an international network of artists working in Paris in those years and beyond.
