A Western View of part of Westminster and Bird Cage Walk taken from the Mill House George Arnald (1763-1841)

The picture has something of this: tree, people, house, landscape, building, church, river, farm, agriculture, architecture, fence, city, mammal, home, outdoors, livestock, light, cavalry, dawn.
Perhaps it’s a painting of a group of people on a field with a cow in the foreground and a building in the background with people on the other side of the field.
