Definition:
A term used to describe art where the idea is the work of art and is more important than the execution. In its ultimate form, Conceptual Art has no physical form, as a painting does, but exists only as words (written or verbal) that convey the concept, or idea. The Conceptual Art movement emerged in the late 1960s and early 70s.
In 1967 the American artist Sol LeWitt defined Conceptual Art as where the "idea itself, even if not made visual, is as much a work of art as any finished product".
One of the forerunners and influences of Conceptual Art was Marcel Duchamp. The piece most often cited is his "The Fountain" -- an upside-down urinal signed "R. Mutt".
