This is a black and white illustration depicting the interior of the Colosseum. The image is a cross-section view, showing multiple levels of arched openings and stone structures. The lower levels feature a series of rounded arches supported by columns or pillars. Above these arches, there are more arches and openings, creating a layered effect. The upper portion of the image shows a fragmented wall with rectangular openings. The overall impression is one of age, decay, and the grandeur of ancient Roman architecture. The style of the illustration is detailed and reminiscent of a historical engraving. The text at the bottom reads 'Interior of Colosseum' and '1885'.
