A Bedouin Encampment by a Ruined Temple Alexandre-Gabriel Decamps (1803-1860)

The picture has something of this: outdoors, landscape, sky, desert, rock, dawn, nature, mountain, architecture, sunset, daylight, water, hill, sand, wasteland, scenic, stone.
Perhaps it’s a painting of a group of people sitting in a field next to a body of water with a pyramid in the background.
