Following the threepreviousimages that show the actual marble fragments from which Piranesi crafts his own cartographic, historical, and archaeological vision in the “Pianta di Roma,” this image takes a radically close-up look at a structure that is crucial for Piranesi’s approach to Rome. It is a gateway into the volume’s 60 plates of similar sizes, Piranesi’s representation of the city’s ancient remains, and his priorities and methods. It focuses on the construction methods of the Aurelian Wall, a defensive city wall built in the 270s CE and frequently rebuilt and renovated over many centuries. Against a naturalistic background—there is a wedge of a faintly cloudy sky and a hint of vegetation toward the upper left—the plate foregrounds information, with roughly one eighth of its space devoted to a caption that itemizes building materials: tevolozza, opus incertum, and tegoloni. Near the center, five illuminated triangular stones are increasingly exposed along the descent of the wall’s façade. To the right, a large but obscured letter “A” identifies these stones as tevolozza. The wall’s inner material—identified in the caption as opus incertum (B)—is bound by layers of large square tiles (C) that are marked by the master of the kiln (D). In the preface to the Index to the Map of Rome, Piranesi refers to this image for its display of construction methods that were able to render the wall “stabile e ferma” and by which its innards were “nudrite.” After pointing, in a cross-reference, to the following plate, which also depicts the wall, he then begins “our stroll” through the itinerary of the Map of Rome and the contents of the volume.
