Dionysius of Halicarnassus, Roman Antiquities 6.17
 Having thus checked the rash impulse of the soldiers, he commanded the men to depart without looking back, and put them in charge of a guard of horse, who conducted them to the camp of the Volscians. After he had expelled the spies, he commanded the soldiers to get everything ready for battle, as if he were going to engage the next day. But he had no need of a battle, for the leaders of the Volscians broke camp before dawn and returned home. 2 All things having now gone according to his wish, he buried his own dead, and having purified his army, returned to the city with the pomp of a magnificent triumph, together with huge quantities of military stores, followed by 5,500 prisoners taken in the battle. And having set apart the tithes of the spoils, he spent forty talents in performing games and sacrifices to the gods, and let contracts for the building of temples to Ceres, Liber and Libera, in fulfilment of a vow he had made. 3 It seems that provisions for the army had been scarce in the beginning, and had caused the Romans great fear that they would fail entirely, as the land had borne no crops and food from outside was no longer being imported because of the war. Because of this fear he had ordered the guardians of the Sibylline books to consult them, and finding that the oracles commanded that these gods should be propitiated, he made vows to them, when he was on the point of leading out his army, that if there should be the same abundance in the city during the time of his magistracy as before, he would build temples to them and also appoint sacrifices to be performed every year. 4 These gods, hearing his prayer, caused the land to produce rich crops, not only of grain but also of fruits, and all imported provisions to be more plentiful than before; and when Postumius saw this, he himself caused a vote to be passed for the building of these temples. The Romans, therefore, having through the favour of the gods repelled the war brought upon them by the tyrant, were engaged in feasts and sacrifices.
