The Roman antiquities, t. 4, Plate XIII. Cross-section and construction details of Bridge St. Angel etc.. 

This etching, part of Giovanni Battista Piranesi's "Roman Antiquities" series, depicts a detailed cross-section and construction details of the Bridge of St. Angel in Rome. Piranesi, known for his dramatic and meticulous depictions of ancient Roman architecture, used a technique known as "veduta" to showcase the bridge's impressive scale and grandeur. The etching features the bridge's multiple arches, its sturdy stonework, and the surrounding cityscape, all rendered with remarkable precision. Piranesi's work celebrates the enduring power of Roman engineering and design, while also providing valuable insight into the construction techniques of the ancient world.
