Venne, Adriaen Pietersz. van de – Het vertrek van een hoogwaardigheidsbekleder uit Middelburg, 1615 Rijksmuseum: part 1

The picture has something of this: group, watercraft, people, transportation system, many, vehicle, ship, river, water, sailboat, boat, cavalry, bridge, landscape, flag, sea.
Perhaps it’s a painting of a large body of water with a lot of boats in it and people on the side of the water and onlookers on the other.
