A painting is an object which has an emphatic frontal surface. On such a surface, I paint a black band which does not recede, a color band which does not obtrude, a white square or rectangle which does not move back or forth, to or fro, or up or down; there is also a painted white exterior frame band which is edged round the edge to the black. Every part is painted and contiguous to its neighbor; no part is above or below any other part. There is no hierarchy. There is no ambiguity. There is no illusion. There is no space or interval (time).
