Note 97 — Chapter IV · PART I. THE AQUEDUCTS.
Reading edition
This water is now usually called Acqua di Trevi, because its terminus is at the great fountain of Trevi. The sources are in the estate of Salone, as above described. It is still in use, and was long considered as the best water brought into Rome. The line now used is the one repaired and restored by the Popes; but, near Rome, it has been altered, probably after it had been damaged by the Goths or the Lombards. The old specus passed through the Catacomb of S. Priscilla, in the Via Salaria, where it may be seen. This is demonstrated by the cippus of the aqueduct of Virgo, discovered in the Via Salaria, and so recorded by Muratori, Thes. Vet. Inscr., ccccxlii. 7, “Romæ in Via Salaria:”—

This inscription is A.D. 36.
It was then brought to the bank or mœnia on which the wall of Aurelian was afterwards built near the Porta Salaria, and may be traced upon or in that bank under the present wall of Rome for about a mile. For a short distance, where this ground is low, it was carried on an arcade, of which there are remains under the wall built upon it. After this it goes on as far as the garden of the Villa Borghese and the French Academy, under which it now passes through the Pincian Hill.
