La Vision artistique de la montagne : panorama, pli ou plongée ? by Marie-Madeleine Martinet

“…Lastly, the vertical dimension, angled views and peaks, brought a new approach to perspective and the corresponding optical illusions.Mountains, a strange world, brought about inverted visual effects with the most irregular shapes prevailing over landscapes; and they were first studied in distant countries where their unusual appearance seemed less unexpected, before being discovered at home as an artistic subject…”
