The models for Renoir’s famous painting Luncheon of the Boating Party (1880–1881)were fellow artists, critics, collectors and friends, and this exhibition catalogue takes the picture as a starting point to explore Renoir’s world. The artist’s style and influences are assessed through the work of contemporaries, including Caillebotte, Degas and Manet, and the painting is forensically examined, including X-ray images that reveal hidden details.
