Renoir suffered from debilitating rheumatoid arthritis for those last three decades or so of his life. His hands were deformed, his joints severely damaged, and he was wheelchair-bound for most of his later years. He adapted his painting techniques to cope: his children or other assistants held his palettes, placed paintbrushes in his permanently curled fingers, and even moved his canvases underneath his paintbrush so that he could hold his arm still to reduce the pain. In 1915 a young Matisse asked Renoir why he still painted when it was obvious just how much he suffered. Renoir answered thus: “The pain passes but the beauty remains.”
