Salomon Gessner – Arcadian Landscape with an Obelisk National Gallery of Art (Washington)

The picture has something of this: tree, landscape, nature, fall, leaf, mist, dawn, fog, wood, sky, outdoors, water, park, fair weather, sun, light, branch, countryside.
Perhaps it’s a painting of a wooded scene with people on a path and a horse and buggy in the foreground and a castle on a hill in the background.
