In the fourth year of the siege the Romans suffered no small loss. First Anxur was lost, the garrison being surprised by the Volscians, and afterwards there followed great reverses at Veii. The men of Capena and Falerii came to the help of Veii, judging that if this city should be taken they themselves would be the next to perish. These fought against a certain part of the Romans, and at the same time the townsfolk sallied from the gates. And when help should have been given to them from the other part of the camp, because there was a strife between the generals, none such was sent; for the one said, "If my colleague be in need of help he will ask for it," and the other, for pride and jealousy, had rather be conquered by the enemy than conquer by aid of one whom he loved not. So it came to pass that Sergius (for he it was whom the men of Capena and Falerii had attacked) with his soldiers left the works and fled, some escaping to the other camp, but the greater part making escape to Rome.
In the seventh year of the siege there happened many marvels. Of these, for the most part? men took little count; but one seemed especially noteworthy, to wit, that the water of the lake of Alba rose to such a height as had never been seen before, and this without great rains or any other cause which might make the thing less to be wondered at. Messengers therefore were sent to the oracle of Delphi to enquire of the god what this might portend. But the Romans found, for so fate would have it, an interpreter of the marvel that was nearer at hand than the oracle of Apollo. As the Roman soldiers and the soldiers of Veii talked together at the outposts, a certain old man, an Etrurian, chanted in the fashion that prophets use this verse--
"Ne'er till the depths of Alba's lake be drained Shall Veii's walls by Roman arms be gained."
Of these words none at first took any heed, but afterwards some began to doubt what they might mean. A certain Roman therefore enquired of the townsfolk (for the siege having now endured for many years there had grown up acquaintance between them) who the man might be that had chanted this prophecy. And when he heard he was a soothsayer, he spake to him, saying that he would fain have some talk with him, for that there had happened to himself a certain marvel, and he desired to know how he might rightly deal with it. So the two went to a certain place by themselves, neither of them carrying arms. Then the Roman (for he was a young man and of great strength) caught up the Etrurian in his arms and carried him away to the camp, the Etrurians not being able to hinder him. So they brought the soothsayer to the general, and the general sent him to the Senate; and when the Senate enquired of him what it was that he had prophesied concerning the lake of Alba, the old man answered, "Surely the Gods were wroth with Veii that day when they put it into my mind to betray the thing which by the ordering of fate must bring about the destruction of the city. Nevertheless I cannot recall that which I once uttered by divine inspiration so that it should be as if it were unsaid; and perchance there is no less wickedness in concealing that which the immortal Gods would have revealed than in uttering that which they would have concealed. Know therefore that in the books of fate and in the lore of the Etrurians it is written that if ever the water of the lake of Alba shall increase, the Romans, draining it off in due manner, shall prevail over the men of Veii, but that before that shall have been done, the Gods will not desert the walls of the city." And when he had said this he expounded to them what the due manner of draining off the water might be. Nevertheless because the man seemed to be of small authority, upon whom it would not be well to trust in so great a matter, the Senate determined that messengers should be sent to enquire of the god at Delphi. In the ninth year of the war these messengers returned, bringing back this answer from the god.
