Pierre-Auguste Renoir, French, 1841-1919 – The Great Bathers Philadelphia Museum of Art

The picture has something of this: nude, people, group, man, shirtless, woman, son, reclining, Renaissance, saint, two, tree, god, three, nymph, baroque.
Perhaps it’s a painting of a group of naked women sitting next to each other near a body of water with trees in the background and one woman in the foreground.
