Paul Cézanne was famous for his play of flatness and volume in still lifes and landscapes. Pierre-Auguste Renoir was celebrated for his tremulous, light-dappled portraits and landscapes. These artists had distinct styles, but behind closed doors they were good friends. In the 1880s, Cézanne was unfashionable and Renoir helped him obtain his first solo exhibition. In the meantime, Cézanne picked up some of Renoir’s feathery brilliance. This important exhibition places their work side by side. Picasso’s Large Still Life (1917) and Large Nude with Drapery (1923)—made in tribute to the artists—close out the show. —Elena Clavarino
