The Arch with a Shell Ornament, Imaginary Prisons plate 11
Dense black etching shows a vast vaulted prison interior, with tall arches receding into shadow and wooden cranes, beams and ladders crowding the foreground. Tiny figures stand on walkways among the machinery, and the fine parallel lines give the scene a dim, labyrinthine depth.
