The Marsh Constant Troyon (1810-1865)

The picture has something of this: tree, landscape, nature, sky, fall, water, dawn, outdoors, light, sunset, wood, grass, river, park, lake, sun, fair weather, reflection.
Perhaps it’s a painting of a group of people on a path by a river in a wooded area with cows grazing in the foreground and a blue sky with clouds in the background.
