In 'The Boating Party Lunch', a group of Renoir's friends are enjoying that supreme delight of the working man and woman, a day out. Renoir shows us interrelationships: notice the young man intent upon the girl at the right chatting, while the girl at the left is occupied with her puppy. But notice too the loneliness, however relaxed, that can be part of anyone's experience at a lunch party. The man behind the girl and her dog is lost in a world of his own, yet we cannot but believe that his reverie is a happy one. The delightful debris of the meal, the charm of the young people, the hazy brightness of the world outside the awning - all communicates an earthly vision of paradise.

Renoir is perhaps the best-loved of all the Impressionists for his subjects. Pretty children, flowers, beautiful scenes, and above all lovely women, have instant appeal and he communicated the joy he took in them with great directness. `Why shouldn't art be pretty?', he said, `There are enough unpleasant things in the world.' He was one of the great worshippers of the female form, and he said `I never think I have finished a nude until I think I could pinch it.' One of his sons was the celebrated film director Jean Renoir (1894-1979), who wrote a lively and touching biography (Renoir, My Father) in 1962.
