bergиre gardant ses moutons Jean-François Millet (1814-1875)

The picture has something of this: mammal, people, two, herder, group, cattle, livestock, wear, farming, man, outdoors, sheep, agriculture, cavalry, cropland, woman.
Perhaps it’s a painting of a woman standing in front of a herd of sheep with a dog on the other side of the painting, with a sky in the background.
