The perceval is a square in air. A single one can cover the globe but no less than one can cover the human heart. One exists for every atom or hovers over the beggar in the subway. One contains a pair of subatomic particles separated by miles but matching spin or expands over grandfather's grave to contain the flowers, pumpkin, and M&M's placed there by his grandchildren. One exists for each rivet that holds the steel trusses of the bridge we go under everyday or cocoons the Inuit elder who walks onto the ice to sit and wait when the food in his village is not enough. One covers the stars and nebulae in the Oort Cloud or envelops a supercluster of galaxies between unimaginably vast regions of void. A broken one held the passengers of Flight 800 as they flew free of a cockpit through 2 miles of ocean night air. One perceval holds all that you have done. Brandywine 1/27/99
