This piece is called Study of a Women's Back, by Henri Matisse. The artist relied mostly on line to create this piece. Almost all art begins with line, which leads to the artist incorporating other visual elements. Although the piece does have other visual elements in their rawest forms, Matisse choose not to develop these, and instead concentrate on line.
