Bicycle Wheel
In 1913, at a moment when art was still largely defined by craftsmanship, painting, and sculpture, Marcel Duchamp introduced Bicycle Wheel. Instead of creating a new form, he selected and combined two ordinary manufactured objects. At a time when the value of art was closely tied to skill and manual labor, Duchamp shifted the focus away from making and toward choice, proposing that the artistic act could exist purely in the decision to designate an object as art.
