Year after year the army besieged the strong place, and there seemed no hope that its walls would fall. It was allied with Fidenæ, another city halfway between it and Rome, which was taken by means of a mine in the year 426. A peace with Veii ensued, after which the incessant war began again, and fortune sometimes favored one side and sometimes the other. The siege of the city can be fittingly compared to that of Troy, Seven years had passed without result, when of a sudden, in the midst of an autumn drought, the waters of the Alban Lake, away off to the other side of Rome, began to rise. Higher and still higher they rose without any apparent cause, until the fields and houses were covered, and then they found a passage where the hills were lowest, and poured down in a great torrent upon the plains below. Unable to understand this portent, for such it was considered, the Romans called upon the oracle at Delphi for counsel, and were told that not until the waters should find their way into the lowlands by a new channel, should not rush so impetuously to the sea, but should water the country, could Veii be taken. It is hardly necessary to say that no one but an oracle or a poet could see the connection between the draining of a lake fifteen miles from Rome on one side, and the capture of a fortress ten miles away on the other. However, the lake was drained. With surprising skill, a tunnel was built directly through the rocky hills, and the waters allowed to flow over the fields below. The traveller may still see this ancient structure performing its old office. It is cut for a mile and a half, mainly through solid rock, four feet wide and from seven to ten in height. The lake is a thousand feet above the sea-level, and of very great depth. Marcus Furius Camillus is the hero who now comes to the rescue. He was chosen dictator in order that he might push the war with the utmost vigor. The people of Veii sent messengers to him to sue for peace, but their appeal was in vain. Steadily the siege went on. We must not picture to ourselves the army of Camillus using the various engines of war that the Romans became acquainted with in later times through intercourse with the Greeks, but trusting more to their strong arms and their simple means of undermining the walls or breaking down the gates. Their bows and slings and ladders were weak instruments against strong stone walls, and the siege was a long and wearisome labor. It proved so long in this case, indeed, that the soldiers, unable to make visits to their homes to plant and reap their crops, were for the first time paid for their services. As the unsuccessful ambassadors from Veii turned away from the senate- house, one of them uttered a fearful prophecy, saying that though the unmerciful Romans feared neither the wrath of the gods nor the vengeance of men, they should one day be rewarded for their hardness by the loss of their own country.
