Inspired by a highly ornate set design by Filippo Juvarra (1678–1736), Piranesi produced this expressive, gestural ink drawing as an inventive interpretation of the original source. He altered its format from vertical to horizontal, and strengthened the shadows in the foreground to pull the viewer into a much more brooding, charged space. However, Piranesi retained the innovative 'scena per angolo' perspective, where one vanishing point gives way to two, resulting in an image that makes sense from multiple points of view.
