Mountain landscape with deserted river, classical ruins and shepherds Lodewijk (Pozzoserrato) Toeput (1550-1605)

The picture has something of this: water, cave, rock, landscape, tree, light, river, people, geology, underwater, environment, grotto, nature.
Perhaps it’s a painting of a landscape with people and animals in the foreground and a castle on a hill in the background, with a river running through the foreground.
