separated the river from the Nera. The level of this canal was from 130 to 140 feet above the river, and this gave rise to the matchless cascade, of course without any intention on the part of Curius, for it was not his object to create beautiful scenery. A person who has seen that waterfall, can no longer take any pleasure in that of the Rhine, near Schaffhausen. Every one knows the canal through the rock, for thousands of travellers visit the falls of Terni, and generally drive about a mile further to lake Lugo for the purpose of hearing the beautiful echo. I visited it accompanied by my friend Brandis; I knew what is generally known in Italy, though not so generally in Germany, that there is a cutting through the rock, and I said to our guide that I wanted to go up the canal as far as the lake. The man made difficulties, saying that it was not a road for gentlemen, but fit only for rustics. But I insisted on carrying out my plan, and we thus came to the canal which is cut through the rock at an immense depth. When the man observed that we were interested in it, he said, I will take you to see another curiosity, which no one goes to see, if the road is not too difficult for you. It was a Roman bridge, the existence of which was then altogether unknown: it consists of a single arch, and is a splendid work constructed of large blocks without any cement—a work like the cloacae; there can be no doubt that this bridge also is a work of Curius. It is not mentioned in any book of travel. The same guide told us that the people of Reate and Terni once had a law-suit about an aqueduct, and that the former applied to Cicero, and the latter to an advocate of the last century:[50] a remarkable instance of the manner in which legends arise.
