Venne, Adriaen Pietersz. van de – De zielenvisserij, allegorie op de ijverzucht van de verschillende religies tijdens het Twaalfjarig Bestand tussen de Nederlandse Republiek en Spanje, 1614 Rijksmuseum: part 1

The picture has something of this: group, water, people, many, river, landscape, watercraft, lake, sea, transportation system, tree, boat, rowboat, seashore, town, beach.
Perhaps it’s a painting of a large group of people in a body of water with boats and people on the other side of the river and a rainbow in the sky.
