Some walls of Paleolithic caves refused the ancestors' charcoal and mineral paints. Outside too rocks had their say. Silence, so The condition of the world to be re- vealed is also essentially the loss of world at the edge of the pond: step                                         slip                                      fall                                   in Trees send roots, inquisitive limbs droop. Caves, rocks, ponds, below and above, what we think of as the world, is not the world we think of.
