This battle was fought about the summer solstice, the moon being at full, the very same day in which the sad disaster of the Fabii had happened, when three hundred of that name were at one time cut off by the Tuscans. But from this second loss and defeat the day got the name of Alliensis from the river Allia, and still retains it. The question of unlucky days, whether we should consider any to be so, and whether Heraclitus did well in upbraiding Hesiod for distinguishing them into fortunate and unfortunate, as ignorant that the nature of every day is the same, I have examined in another place; but upon occasion of the present subject, I think it will not be amiss to annex a few examples relating to this matter. On the fifth of their month Hippodromius, which corresponds to the Athenian Hecatombaeon, the Boeotians gained two signal victories, the one at Leuctra, the other at Ceressus, about three hundred years before, when they overcame Lattamyas and the Thessalians, both which asserted the liberty of Greece. Again, on the sixth of Boedromion, the Persians were worsted by the Greeks at Marathon; on the third, at Plataea, as also at Mycale; on the twenty-fifth, at Arbela. The Athenians, about the full moon in Boedromion, gained their sea-victory at Naxos under the conduct of Chabrias; on the twentieth, at Salamis, as we have shown in our treatise on Days. Thargelion was a very unfortunate month to the barbarians, for in it Alexander overcame Darius's generals on the Granicus; and the Carthaginians, on the twenty-fourth, were beaten by Timoleon in Sicily, on which same day and month Troy seems to have been taken, as Ephorus, Callisthenes, Damastes, and Phylarchus state. On the other hand, the month Metagitnion, which in Boeotia is called Panemus, was not very lucky to the Greeks; for on its seventh day they were defeated by Antipater, at the battle in Cranon, and utterly ruined; and before, at Chaeronea, were defeated by Philip; and on the very same day, same month, and same year, those that went with Archidamus into Italy were there cut off by the barbarians. The Carthaginians also observe the twenty-first of the same month, as bringing with it the largest number and the severest of their losses. I am not ignorant that, about the Feast of Mysteries, Thebes was destroyed the second time by Alexander; and after that, upon the very twentieth of Boedromion, on which day they lead forth the mystic Iacchus, the Athenians received a garrison of the Macedonians. On the selfsame day the Romans lost their army under Caepio by the Cimbrians, and in a subsequent year, under the conduct of Lucullus, overcame the Armenians and Tigranes. King Attalus and Pompey died both on their birthdays. One could reckon up several that have had variety of fortune on the same day. This day, meantime, is one of the unfortunate ones to the Romans, and for its sake two others in every month; fear and superstition, as the custom of it is, more and more prevailing. But I have discussed this more accurately in my Roman Questions.
And now, after the battle, had the Gauls immediately pursued those that fled, there had been no remedy but Rome must have wholly been ruined, and those who remained in it utterly destroyed; such was the terror that those who escaped the battle brought with them into the city, and with such distraction and confusion were themselves in turn infected. But the Gauls, not imagining their victory to be so considerable, and overtaken with the present joy, fell to feasting and dividing the spoil, by which means they gave leisure to those who were for leaving the city to make their escape, and to those that remained to anticipate and prepare for their coming. For they who resolved to stay at Rome, abandoning the rest of the city, betook themselves to the Capitol, which they fortified with the help of missiles and new works. One of their principal cares was of their holy things, most of which they conveyed into the Capitol. But the consecrated fire the vestal virgins took, and fled with it, as likewise their other sacred things. Some write that they have nothing in their charge but the ever-living fire which Numa had ordained to be worshipped as the principle of all things; for fire is the most active thing in nature, and all production is either motion, or attended with motion; all the other parts of matter, so long as they are without warmth, lie sluggish and dead, and require the accession of a sort of soul or vitality in the principle of heat; and upon that accession, in whatever way, immediately receive a capacity either of acting or being acted upon. And thus Numa, a man curious in such things, and whose wisdom made it thought that he conversed with the Muses, consecrated fire, and ordained it to be kept ever burning, as an image of that eternal power which orders and actuates all things. Others say that this fire was kept burning in front of the holy things, as in Greece, for purification, and that there were other things hid in the most secret part of the temple, which were kept from the view of all, except those virgins whom they call vestals. The most common opinion was, that the image of Pallas, brought into Italy by Aeneas, was laid up there; others say that the Samothracian images lay there, telling a story how that Dardanus carried them to Troy, and when he had built the city, celebrated those rites, and dedicated those images there; that after Troy was taken, Aeneas stole them away, and kept them till his coming into Italy.
But they who profess to know more of the matter affirm that there are two barrels, not of any great size, one of which stands open and has nothing in it, the other full and sealed up; but that neither of them may be seen but by the most holy virgins. Others think that they who say this are misled by the fact that the virgins put most of their holy things into two barrels at this time of the Gaulish invasion, and hid them underground in the temple of Quirinus; and that from hence that place to this day bears the name of Barrels.
