Apollo and the Muses on Mount Helion Parnassus Claude Lorrain (1600-1682)

The picture has something of this: people, tree, group, temple, architecture, outdoors, two, monument, sky, sculpture, building, landscape, step, tower, dawn.
Perhaps it’s a painting of a group of people sitting on a rock next to a body of water with a building in the background and a few swans in the foreground.
