Five other antique bridges crossed the Tiber at or near Rome, but Palladio found nothing more of them than a few remnants. Already I have spoken of two, the Pons Sublicius and its understudy (p. 140). On the left bank, facing the church of S. Spirito, Palladio saw remains of the Pons Triumphalis; but Piranesi and Bunsen do not agree with Palladio. They place the Pons Triumphalis beyond the Pons Ælius, and Sir William Smith thinks it probable that the remains near S. Spirito belong to a bridge which the _Mirabilia_ names Pons Neronianus, and which ancient topographers describe as Pons Vaticanus. Then there was the Janiculine bridge upon the foundations of which, between 1471 and 1484, Pope Sixtus IV had erected the Ponte Sisto. As the Janiculine bridge went from the Janiculum to the Porta Aurelia, it was known also as Pons Aurelius; and in the Middle Ages it seems to have been called Pons Antoninus. As for the Ponte Molle, anciently the Pons Milvius, it belonged to the Flaminian Way, crossing the Tiber beyond the walls of Rome, a mile and a half outside the city. Its founder was said to be the earlier Æmilius Scaurus, who died about eighty-five years before the Birth of Christ. Yet it certainly existed in B.C. 207, for Livy relates how the people poured out of Rome as far as the Milvian bridge in order to meet the messengers who brought tidings of the defeat of Hasdrubal. This may have been a timber bridge, and Æmilius Scaurus may have displaced it for a stone bridge during his consulship, B.C. 110. Only a few fragments of the Pons Milvius existed in Palladio’s time; and so the Ponte Molle now extant has a false reputation of being Roman. In fact, it is a very poor structure, badly designed and very uncouth. IV
