Around 1892, Renoir developed rheumatoid arthritis. In 1907, he moved to the warmer climate of "Les Collettes," a farm at Cagnes-sur-Mer, close to the Mediterranean coast. Renoir painted during the last twenty years of his life, even when arthritis severely limited his movement, and he was wheelchair-bound. He developed progressive deformities in his hands and ankylosis of his right shoulder, requiring him to adapt his painting technique. It has often been reported that in the advanced stages of his arthritis, he painted by having a brush strapped to his paralyzed fingers, but this is erroneous; Renoir remained able to grasp a brush, although he required an assistant to place it in his hand. The wrapping of his hands with bandages, apparent in late photographs of the artist, served to prevent skin irritation.
