The word "cube" was used in 1906 by another critic, Louis Chassevent, with reference not to Picasso or Braque but rather to Metzinger and Delaunay: "M. Metzinger is a mosaicist like M. Signac but he brings more precision to the cutting of his cubes of color which appear to have been made mechanically".
The term Cubism did not come into general usage until 1911, mainly with reference to Metzinger, Gleizes, Delaunay, and Léger. In 1911, the poet and critic Guillaume Apollinaire accepted the term on behalf of a group of artists invited to exhibit at the Brussels Indépendants.
