art is dead 

The statement that the attempt to convey meaning through representation has run its course, and cannot be improved upon, only repeated like a ritual in a vain attempt to recreate the original feeling of "novelty"

Also, could refer to an actual person named Art, who is now deceased.

'Everything has been done before. Art is Dead.'
