Etang Dans Les Oasis- Sahara SnD 1866 O C 111.5 by 142.5cm Eugene Fromentin (1820-1876)

The picture has something of this: tree, landscape, dawn, outdoors, park, wood, nature, environment, daylight, leaf, summer, light, water, sun, grass, fair weather, scenic, lush.
Perhaps it’s a painting of a group of people in a wooded area with a river in the foreground and trees on the other side of the painting is a cloudy sky.
