Corot Orpheus Leading Eurydice from the Underworld Jean-Baptiste-Camille Corot (1796-1875)

The picture has something of this: tree, fog, dawn, mist, people, landscape, sepia, fall, wood, winter, nature, silhouette, leaf, park, vintage, outdoors, haze.
Perhaps it’s a painting of a man and a woman in a wooded area with a lake in the foreground and a group of people on the other side of the painting.
