Étant donnés is a 1966 assemblage by Marcel Duchamp. It was his last major artwork, surprising viewers and critics who had widely believed he had given up art; he was previously pursuing competitive chess which he had been playing for almost 25 years. The artwork is a tableau, visible only through a pair of peepholes—one for each eye—in a wooden door, of a nude woman lying on her back on a hill with her face hidden, legs spread, holding a gas lamp in the air in one hand against a landscape backdrop.
