Jacob  walks out into a cathedral-sized area inside the  cave , lit again with the  vert   lumière . When he is near to us, his  tête  hits the  plafond . When he is  loin  away, his  tête  is closer to his  pieds , which are on the  sol . What is the reason for this distortion? No matter what the cause, it appears that they walls of the  cave  are at a definite distance, even though the folds of the  perdu  walls twist and hide themselves in small shadowed darknesses.     Les coulées de roches entrelacées étaient leurs rayons.
