"In 1914, the Austrian actress Tilla Durieux was driven from Berlin to Paris some 15 times to sit for a portrait by Pierre-Auguste Renoir. In the resulting painting, Durieux looks serenely grave, fixing her gaze somewhere outside its shimmer of rose and honeyed tones. Writing years later, she described the severely arthritic artist. As he was wheeled into the room by a nurse, Durieux was “flabbergasted” by Renoir’s hands. His right, she noted, had been frozen by the arthritis in the gesture of holding a paintbrush; the left was contorted in such a way that it perfectly held a palette."
