This sheet of mosaic window, with its infrathin edges (i.e. with its Duchampian, non-existent, hardly existent edge-edges) is almost physically impalpable (as well as metaphysically improbable), yet it blazes forth with “radiant ignition” (Elaine Scarry uses the phrase in her Dreaming by the Book, 1999) that falls upon the recombinant mind more fully and fleshly than any real window could.  The spavined tree, growing against a clerical, copy-book of wall, needs the nourishment of extension-in-the round, an end to imposition.  Once an impulsive tree, the object has now accepted authorship. We will leave it, then, as a drawing and move on.
