Seated bather Adolphe William Bouguereau (1825-1905)

The picture has something of this: nude, people, woman, cave, portrait, girl, indoors, shirtless, model, sexy, water, man, rock, naked, light, dark, son.
Perhaps it’s a painting of a naked woman with a blue shawl on her head sitting on the ground next to a body of water with a rock in the background.
