Matisse became a painter relatively late in life; he was known as the principal protagonist of Fauvism, the first avant-garde movement at the turn of the century. He went on to develop a monumental decorative art, which was innovative both in its treatment of the human figure and in the constructive and expressive role accorded to colour. His long career culminated in a highly original series of works made of paper cut-outs, which confirmed his reputation, with Picasso, as one of the major artists of the 20th century.
