In many ways Renior was the most traditional of the major Impressionists, the one soaked in the work of early painters. He was the most instinctively professional painter of the group, with a light, sweeping, feathery brush- stroke and greater delicacy and rhythmic unity than Pissarro or even Monet. This showed to particular advantage in his renderings of shimmering light or delicate young skin. His painting of the family of his patron, Georges Charpentier, has a skilful and almost classically organized composition.
