A Urinal, a Revolution

In 1917 Duchamp bought an ordinary porcelain urinal, signed it "R. Mutt," titled it Fountain, and submitted it to an exhibition. The jury was scandalized and refused to show it. But Duchamp’s question remained: if an artist points to a ready-made thing and says "this is art," is it art? This prank of a question forced the whole of twentieth-century art from "how to paint" toward "what even counts as art."
