Matisse is commonly regarded, along with Pablo Picasso, as one of the artists who best helped to define the revolutionary developments in the visual arts throughout the opening decades of the twentieth century, responsible for significant developments in painting and sculpture.
The intense colourism of the works he painted between 1900 and 1905 brought him notoriety as one of the Fauvism (French for "Wild Beat").
