An Interior View of the Colosseum, Rome John Warwick Smith (1749-1831)

The picture has something of this: architecture, building, city, amphitheater, ancient, landscape, church, town, Colosseum, sky, assembly, street, wall, tree, people, stadium.
Perhaps it’s a painting of a group of people playing a game of frisbee in an old castle like setting with a cross in the middle of the painting.
