When Nude Descending a Staircase (No. 2), above, was first exhibited in 1913, viewers found the painting jarring and off-putting. Instead of depicting a single, static moment, French artist Marcel Duchamp illustrates movement and time. He shows motion through repetition and variation, painting the transforming shapes of a figure walking down the stairs.
Duchamp dehumanizes the figure, practically turning it into a machine. “I was interested in ideas—not merely in visual products,” he explained years later. Rather than being stung by criticism he received, Duchamp embraced it and continued to push boundaries in his art.
