Shepherd with cows on river bank Aelbert Cuyp (1620-1691)

The picture has something of this: people, mammal, water, two, group, landscape, dawn, cattle, cavalry, sunset, man, outdoors, beach, river, cow, recreation.
Perhaps it’s a painting of a man sitting on a rock next to a herd of cattle near a body of water with a sailboat in the water in the background.
