The Roman antiquities, t. 4, Plate XXV. Plan of the Theatre of Marcellus. 

This is a detailed architectural drawing of the Theatre of Marcellus, an ancient Roman amphitheatre, by renowned Italian artist and architect, Giovanni Battista Piranesi. This etching, part of his monumental series "Roman Antiquities", shows the theatre’s plan and is a prime example of Piranesi's fascination with Roman architecture. Through precise lines and detailed measurements, Piranesi meticulously captures the complex structure of this iconic monument. The drawing is framed by a decorative border, typical of Piranesi's artistic style, and includes Italian text offering further explanation of the artwork. Piranesi's intricate depictions of Roman ruins revolutionized the understanding of this period and continue to inspire architects and artists today.
