Made on top of Le Buet, facing Mont Blanc, Loppé used this sketch to paint an enormous canvas which now hangs in Chamonix’s Le Majestic. At two and a half metres wide, Coucher de soleil sur la châine de Mont Blanc is a splurge of smouldering orange, red and dark shadows. When comparing the study with its large counterpart, it shows how adept Loppé was at transposing the effect of the setting sun; the strength of the shadows and the colours’ values even on such a small scale. His topographical accuracy was as precise as ever.
