Phyllida and Demophon Sir Edward Burne-Jones (1833-1898)

The picture has something of this: people, nude, man, shirtless, Renaissance, naked, artistic, strong, portrait, person, shape, body, muscle, famous, brawny.
Perhaps it’s a painting of a naked man and a naked woman standing next to each other in front of a body of water with trees and flowers in the background.
