During his censorship one very good act of his is recorded, that, whereas the wars had made many widows, he obliged such as had no wives, some by fair persuasion, others by threatening to set fines on their heads, to take them in marriage; another necessary one, in causing orphans to be rated, who before were exempted from taxes, the frequent wars requiring more than ordinary expenses to maintain them. What, however, pressed them most was the siege of Veii. Some call this people Veientani. This was the head city of Tuscany, not inferior to Rome, either in number of arms or multitude of soldiers, insomuch that, presuming on her wealth and luxury, and priding herself upon her refinement and sumptuousness, she engaged in many honourable contests with the Romans for glory and empire. But now they abandoned their former ambitious hopes, having been weakened by great defeats, so that, having fortified themselves with high and strong walls, and furnished the city with all sorts of weapons offensive and defensive, as likewise with corn and all manner of provisions, they cheerfully endured a siege, which, though tedious to them, was no less troublesome and distressing to the besiegers. For the Romans, having never been accustomed to stay away from home except in summer, and for no great length of time, and constantly to winter at home, were then first compelled by the tribunes to build forts in the enemy's country, and raising strong works about their camp, to join winter and summer together. And now, the seventh year of the war drawing to an end, the commanders began to be suspected as too slow and remiss in driving on the siege, insomuch that they were discharged and others chosen for the war, among whom was Camillus, then second time tribune. But at present he had no hand in the siege, the duties that fell by lot to him being to make war upon the Faliscans and Capenates, who, taking advantage of the Romans being occupied on all hands, had carried ravages into their country, and, through all the Tuscan war, given them much annoyance, but were now reduced by Camillus, and with great loss shut up within their walls.
And now, in the very heat of the war, a strange phenomenon in the Alban lake, which, in the absence of any known cause and explanation by natural reasons, seemed as great a prodigy as the most incredible that are reported, occasioned great alarm. It was the beginning of autumn, and the summer now ending had, to all observation, been neither rainy nor much troubled with southern winds; and many of the lakes, brooks, and springs of all sorts with which Italy abounds, some were wholly dried up, others drew very little water with them; all the rivers, as is usual in summer, ran in a very low and hollow channel.
But the Alban lake, that is fed by no other waters but its own, and is on all sides encircled with fruitful mountains, without any cause, unless it were divine, began visibly to rise and swell, increasing to the feet of the mountains, and by degrees reaching the level of the very tops of them, and all this without any waves or agitation. At first it was the wonder of shepherds and herdsmen; but when the earth, which, like a great dam, held up the lake from falling into the lower grounds, through the quantity and weight of water was broken down, and in a violent stream it ran through the ploughed fields and plantations to discharge itself in the sea, it not only struck terror into the Romans, but was thought by all the inhabitants of Italy to portend some extraordinary event. But the greatest talk of it was in the camp that besieged Veii, so that in the town itself, also, the occurrence became known.
As in long sieges it commonly happens that parties on both sides meet often and converse with one another, so it chanced that a Roman had gained much confidence and familiarity with one of the besieged, a man versed in ancient prophecies, and of repute for more than ordinary skill in divination. The Roman, observing, him to be overjoyed at the story of the lake, and to mock at the siege, told him that this was not the only prodigy that of late had happened to the Romans;others more wonderful yet than this had befallen them, which he was willing to communicate to him, that he might the better provide for his private interests in these public distempers. The man greedily embraced the proposal, expecting to hear some wonderful secrets; but when, by little and little, he had led him on in conversation and insensibly drawn him a good way from the gates of the city, he snatched him up by the middle, being stronger than he, and, by the assistance of others that came running from the camp, seized and delivered him to the commanders. The man, reduced to this necessity, and sensible now that destiny was not to be avoided, discovered to them the secret oracles of Veii; that it was not possible the city should be taken, until the Alban lake, which now broke forth and had found out new passages, was drawn back from that course, and so diverted that it could not mingle with the sea. The senate, having heard and satisfied themselves about the matter, decreed to send to Delphi, to ask counsel of the god. The messengers were persons of the highest repute, Licinius Cossus, Valerius Potitus, and Fabius Ambustus; who, having made their voyage by sea and consulted the god, returned with other answers, particularly that there had been a neglect of some of their national rites relating to the Latin feasts; but the Alban water the oracle commanded, if it were possible, they should keep from the sea, and shut it up in its ancient bounds;but if that was not to be done, then they should carry it off by ditches and trenches into the lower grounds, and so dry it up; which message being delivered, the priests performed what related to the sacrifices, and the people went to work and turned the water.
