The literalization of the picture plane is a great subject. As the vessel of content becomes shallower and shallower, composition and subject maker and metaphysics all overflow across the edge until, as Gertrude Stein said about Picasso, the emptying out is complete. But all the jettisoned apparatus- hierarchies of painting, illusion, locatable space, mythologies beyond number- bounced back in disguise and attached themselves, via new mythologies, to the literal surface which had apparently left them no purchase. The transformation of literary myths into literal myths- objecthood, the integrity of the picture plane, the equalization of space, the self-sufficiency of the work, the purity of form- is unexplored territory. Without this change art would have been obsolete. Indeed its changes often seem one step ahead of obsolescence, and to that degree its progress mimics the laws of fashion.
