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 of the many lakes, brooks, and springs of all sorts with which Italy abounds, some were wholly dried up, others had very little water in them; all the rivers, as is usual in summer, ran in a very low and hollow channel. But the Alban lake, which 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 some 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.
