Piranesi, Juvarra, and the Triumphal Bridge tradition

(144.) Piranesi, 1762, pl. II. "Scenographia Campi Martii...."

(145.) Piranesi, 1756, vol. 1, 12: "88. Avanzo di una delle pile del Ponte Trionfale, composta di grossi travertini, peperini, e di opera incerta. Questo si vede alla ripa del Tevere, molto scoperto ne' tempi estivi, e si dimostra nella Tavola XIII del Tomo IV" (Remains of one of the piers of the Pons Triumphalis, composed of big blocks of travertine, peperino, and of opus incertum. This can be seen on the banks of the Tiber, extensively uncovered in summer, as is shown in plate 13 of volume 4).

Marchetti, "Di tin antico molo per lo scarico dei marmi riconosciuto sullariva sinistra del Tevere," Bulletino della Commissione Archeologica Comunale di Roma, 1891: 45-60, pls. 3, 4; and Martin Maischberger, Marmor in Rom: Anlieferung, Lager- and Werkplatze in der Kaiserzeit (Wiesbaden: Dr. Ludwig Reichert, 1997), 101, figs. 49, 50. It is also recorded in a sketch by Lanciani of 1890 (Maischberger, 105, fig. 51).

(148.) Stefano Piale, in a note to the 1824 edition of Ridolfino Venuti, Accurate e succinta descrizione topografica delle antichita di Roma (1763), with notes and additions by Stefano Piale, 3d ed., 2 vols. (Rome; Pietro Piale and Mariano de Romanis, 1824), vol. 2, 190, observed that Piranesi's account, which Venuti had accepted, had since been corrected on the grounds that the order of the bridges given in the Regional Catalogues placed the Pons Triumphalis downstream of the Pons Aelius, not upstream at Tor di Nona, and that about twelve years earlier, in an attempt to remove the remains below the Pons Aelius, the remains of the structures that Piranesi referred to (his "rimasuglio di abitazione") were found, and that these had bean identified as having been built onto the piers as a defensive measure against Saracen incursions. See also A. Cametti, "La Torre di Nona e la contrada circonstante," Archivio Societa Romana di Storia Patria 39 (1916): 411-66, at 415.

(149.) L. Quilici, "Il Campo Marzio occidentale," Analecta Romana Instituti Danici, suppl. 10 (1983), dates it to the Augustan period and suggests that it may be identifiable with the Ciconiae, a wharf on the Tiber not far from the bend at S. Giovanni dei Fiorentini, recorded in an inscription of the second half of the 3rd century C.E. Maischberger (as in n. 146), 100-107, argues that it was a wharf for the unloading of marble.
