Recumbent Nymph, 1870 Anselm Friedrich Feuerbach (1829-1880)

The picture has something of this: nude, water, people, sea, woman, ocean, underwater, naked, shirtless, swimming, girl, body, reclining, beach, recreation, sexy, portrait.
Perhaps it’s a painting of a naked woman laying on a bed with a leopard on the side of her body.
