What is so interesting about these North American painters from the 18th and 19th centuries is what they painted. Artifacts, ways of life, towns, native people and a world that has long ago disappeared. They paint a completely different world than one is accustomed to from cinema versions of the American west. Charles Deas suffered a mental breakdown and was confined to an institution for many years at the end of his life. I could not find the paintings he created while institutionalized.
