Constantin Hansen – Columns of the Temple of Neptune at Paestum Metropolitan Museum: part 3

The picture has something of this: architecture, outdoors, wood, house, ancient, building, daylight, abandoned, home, door, doorway, sky, gate, construction, landscape, window, wall.
Perhaps it’s a painting of the ruins of a building with a view of a field and mountains in the distance, with a blue sky in the foreground.
