Murillo, Bartolome Esteban. Sheep at Watering Hermitage ~ part 08

The picture has something of this: invertebrate, water, wildlife, underwater, nature, biology, environment, mammal, fish, side view, poultry, reptile, animal, reproduction, food, agriculture, park.
Perhaps it’s a painting of a herd of sheep standing next to each other in a dark area with a person.
