If, after the battle, the Gauls had at once followed up the fugitives, nothing could have prevented their taking Rome and destroying every one who was left in it; such terror did the beaten troops produce when they reached home, and such panic fear seized upon every one. However the barbarians scarcely believed in the completeness of their victory, and betook themselves to making merry over their success and to dividing the spoils taken in the Roman camp, so that they afforded those who left the city time to effect their escape, and those who remained in it time to recover their courage and make preparations for standing a siege.

One of their first acts was to convey most of their holy things into the Capitol, while the Vestal virgins took the sacred fire and their other sacred objects and fled with them from the city. Some indeed say that nothing is entrusted to them except the eternal fire, which King Numa appointed to be worshiped as the origin of all things. For fire has the liveliest motion of anything in nature; and everything is produced by motion or with some kind of motion.
