Cubism refers to an avant-garde art movement that started in Europe. Artists experimented with deconstructing and rearranging their subjects into geometric shapes. Cubists often demonstrate a fragmented three-dimensional (3D) reality on a flat surface by combining different angles of a subject (such as the side and front view). Pablo Picasso, one of the movement’s leading artists, often reassembled parts and angles of the human face or body in his artworks, as exemplified in Seated woman or Woman in a wicker chair (Femme assise ou Femme dans un fauteuil d’osier) and Portrait of Marie-Thérèse Walter.
