Unknown Artist – Horatius Cocles verdedigt de Pons Sublitius, 1425 - 1474 Rijksmuseum: part 1

The picture has something of this: Gothic, ancient, Renaissance, architecture, saint, wall, antique, church, fresco, mosaic, museum, people, decoration, sculpture.
Perhaps it’s a painting of a large group of people in front of a building with a horse drawn carriage in the foreground.
