Marie-Anne de Bourbon-Conde (1697-1741) with the Mineral Water at Chantilly Jean Marc Nattier

The picture has something of this: people, man, group, woman, two, sit, family, recreation, reclining, water, three, child, leisure, enjoyment, son, girl, outdoors.
Perhaps it’s a painting of a woman, two children, and a man sitting on a couch in front of a body of water with a house in the background.
