[137] Probably the text of Frontinus here is corrupt, because the Piscina Limaria and the specus of Claudius are at the forty-sixth mile on the Via Sublacensis, “ad milliarium quadragesimum secundum,” for “Ad milliarium quadragesimum sextum.”
[138] Dr. Fabio Gori, who is a native of Subiaco, claims the credit of being the first person to point out what this great work of Trajan really was. He also states that the Rivus Herculaneus, rising at thirty-eight miles on the Via Sublacensis, must have been a clear stream, which he finds on the left side of the river, opposite to the lake of S. Lucia and to this source of the aqueduct of the Claudia, called Acqua dell’ Arco, or water of the aqueduct.

[140] The piscina made in one of the towers in the wall at the point where it enters Rome, has the four chambers visible, the inner wall of the tower having been destroyed.
