A question was then raised in the Senate by Arruntius and Ateius whether, in order to restrain the inundations of the Tiber, the rivers and lakes which swell its waters should be diverted from their courses. A hearing was given to embassies from the municipal towns and colonies, and the people of Florentia begged that the Clanis might not be turned out of its channel and made to flow into the Arnus, as that would bring ruin on themselves. Similar arguments were used by the inhabitants of Interamna. The most fruitful plains of Italy, they said, would be destroyed if the river Nar (for this was the plan proposed) were to be divided into several streams and overflow the country. Nor did the people of Reate, remain silent. They remonstrated against the clos- ing up of the Veline lake, where it empties itself into the Nar, "as it would burst in a flood on the entire neighbourhood. Nature had admirably provided for human interests in having assigned to rivers their mouths, their channels, and their limits, as well as their sources. Regard, too, must be paid to the different religions of the allies, who had dedicated sacred rites, groves, and altars to the rivers of their country. Tiber himself would be altogether unwilling to be deprived of his neighbour streams and to flow with less glory." Either the entreaties of the colonies, or the difficulty of the work or superstitious motives prevailed, and they yielded to Piso's opinion, who declared himself against any change.
