SECTION D'OR

(French: Golden Section), group of Cubist painters concerned with the proportion and rhythm of geometric forms. The group's name was suggested by Jacques Villon, and the principal members included Robert Delaunay, Marcel Duchamp, Raymond Duchamp-Villon, Albert Gleizes, Juan Gris, Roger de La Fresnaye, Fernand Lger, Andr Lhote, Louis Marcoussis, Jean Metzinger, Francis Picabia, and Andre Dunoyer de Segonzac. The group first exhibited together at the Galerie La Botie in Paris in 1912, and it also published a short-lived magazine entitled Section d'Or. The start of World War I in 1914 ended the activities of the group, which had never been more than a loose association.
