Claude Monet, French, 1840-1926 – Green Park, London Philadelphia Museum of Art

The picture has something of this: mammal, agriculture, livestock, farm, cattle, landscape, cavalry, cow, cropland, outdoors, tree, grass, field, hayfield, daylight, grassland, countryside, sheep, group.
Perhaps it’s a painting of a group of people on a grassy field with a building in the distance and trees on the other side of the field and people.
