Festa Napolitana Nicolas Antoine Taunay (1755-1830)

The picture has something of this: people, group, dog, many, mammal, tree, recreation, crowd, lid, wear, vehicle, cavalry, man, group together, woman, landscape, road, transportation system.
Perhaps it’s a painting of a group of people in a wooded area with a castle in the background and a man on a horse in the foreground with a dog.
