The image shows a pencil sketch of an ancient stone archway, viewed from a slightly off-center position. The horizon is not visible. The stone blocks that make up the arch are depicted with visible pencil strokes indicating texture and solidity, with shadowing under the arch. A variation in pencil pressure creates darker contours and lighter shading for surfaces. The color palette is monochromatic, using shades of grey to represent the stone and light and shadow effects. The balance between solid forms of the stones and softer background elements like foliage or rough surfaces is delicate. In the bottom right corner, the notation "Rome 1857" provides location and date information.
