Marcel Duchamp prized the intellectual rigor of chess, and he sought a similarly conceptual basis for his art. This painting depicts the artist’s older brothers facing each other across a chessboard: Raymond Duchamp-Villon on the left, and Jacques Villon on the right. Their profiles repeat to suggest the unfolding of their attention over time, and the chess pieces that float in the narrow area between them represent the players’ mental projections of the game. Duchamp said that he achieved his mauve-gray color scheme, a version of the subdued Cubist color palette, by painting under moody, flickering gaslight.
