Étant donnés (Given: 1. The Waterfall, 2. The Illuminating Gas, French: Étant donnés: 1° la chute d'eau / 2° le gaz d'éclairage.) is Marcel Duchamp's last major art work which surprised most of the art world, who believed he had given up art for competitive chess almost 25 years earlier, following The Bride Stripped Bare by Her Bachelors, Even (also known as The Large Glass). It is a tableau, visible only through a pair of peep holes (one for each eye) in a wooden door, of a nude woman lying on her back with her face hidden and legs spread holding a gas lamp in the air in one hand against a landscape backdrop.
