Art's relation to time is plural...

Alexander Nagel and Christopher Wood-

"No device more effectively generates the effect of a doubling or bending of time than the work of art, a strange kind of event whose relation to time is plural. The artwork is made or designed by an individual or a group of individuals at some moment, but it also points away from that moment, backward to a remote ancestral origin, perhaps, or to a prior artifact, or to an origin outside of time, in divinity. At the same time it points forward to all its future recipients who will activate and reactivate it as a meaningful event. The work of art is a message whose sender and destination are constantly shifting."
