The picture has something of this: people, cavalry, group, tree, man, competition, mammal, group together, recreation, many, military, festival, flame, seated, action, uniform, woman, weapon, vehicle.
Perhaps it’s a painting of a group of men on horses and dogs in a wooded area with a dog laying on the ground in the foreground of the painting.
