Note 33 — Chapter IV · PART I. THE AQUEDUCTS.

Signor F. Gori, who is a native of Subiaco, and has followed the line of the aqueducts on foot from Subiaco to Rome, says that he has found the source of the Anio Vetus in the river Anio, at three miles from Subiaco, on the Via Sublacensis vetus, twenty miles from the old gate of Tibur or Tivoli, in the district called Le Connotta, where he finds two specus, the higher one the Anio Novus, the lower one the Anio Vetus. He traces the same specus near Marano, a village thirty-eight miles from Rome, on the Via Sublacensis Neroniana, near Vico-varo; and again near Tivoli, on the bank of the Valle degli Arci. “Delle vere Sorgenti dell’ Acqua Marcia e delle altre acque allacciate dai Romani presso le Vie Valeria e Sublacense,” per F.
