Marcel Duchamp's "Roue de bicyclette," a bicycle wheel and wood stool, from 1913. Once upon a time, a masterpiece was a creation that met rigid standards of artistry and craftsmanship. These days, the term usually refers to the best work of an artist's career or an example of outstanding creativity or skill, but there's little agreement on the meaning and relevance of the term, particularly in modern and contemporary art.
