Landscape with the Nymph Egeria Claude Lorrain (1600-1682)

The picture has something of this: tree, water, river, dawn, lake, sunset, reflection, bridge, landscape, people, outdoors, evening, recreation, park, sky, light, fog.
Perhaps it’s a painting of a group of people in a wooded area with a river in the foreground and a castle on the far side of the painting.
