Fishermen With The Bay Of Naples And Vesuvius Beyond Oswald Achenbach (1827-1905)

The picture has something of this: people, group, sunset, dawn, water, outdoors, landscape, cavalry, man, seated, evening, herder, sky, vehicle, mountain.
Perhaps it’s a painting of a group of people standing on a beach next to a body of water with boats in the water and a mountain in the distance.
