Thomas Eakins, American, 1844-1916 – William Rush Carving His Allegorical Figure of the Schuylkill River Philadelphia Museum of Art

The picture has something of this: people, cavalry, mammal, group, man, veil, woman, two, nude, seated, weapon, motion, pain.
Perhaps it’s a painting of a naked woman standing in a room next to a man sitting on a chair and another man standing.
