Fuite Des Turcs Narcisse Virgilio Díaz de la Peña (1807-1876)

The picture has something of this: landscape, dawn, sunset, outdoors, sky, desert, mountain, rock, scenic, volcano, geology, nature, canyon, water, storm, evening.
Perhaps it’s a painting of a large group of people standing in the middle of a field with a sky in the background and clouds in the sky above them.
