The Romans were hugely proud of their victory. Claiming that the siege had lasted ten years, they presented the long campaign against Veii as their version of the Trojan War. And, strategically, it was indeed a great achievement. It signaled the weakening of Etruscan power and the emergence of Rome as the leading state in central Italy. There was also a large domestic benefit. Allotments of the ager Veientanus were distributed to Roman citizens, alleviating plebeian claims of poverty and perhaps helping, at least for now, to mitigate the problem of indebtedness.
But, as so often happens, pride was followed by a fall—in fact, not to put too fine a point on it, the fall of Rome itself. Even Livy, who loyally took the edge off every Roman misfortune, admitted, “Calamity of unprecedented magnitude was drawing near.”
IN 390, A rumor spread that a vast horde of barbarians was moving down Italy—with what purpose in mind nobody knew, but everyone agreed that they posed a terrible threat. For two centuries and more, Celtic tribes had overflowed from their heartlands in central Europe and Asia, crossed the Alps, and (as already noted) poured down into northern Italy, where they settled, and looked covetously at the lands of their southern neighbor, the Etruscan Empire.
The civilized world—that is to say, the Greeks and their admirers the Romans—did not know what to make of these rough, unpredictable tribesmen. The usually reliable Polybius, a Greek who spent much of his life in Rome, wrote:
[They] had no knowledge of the refinements of civilization. They lived in unwalled villages, without any unnecessary furniture. They slept on straw and leaves, ate meat and practised no other pursuits but war and agriculture, so their lives were very simple and they were completely unacquainted with any art or science. Their possessions consisted of cattle and gold, since these were the only objects which they could easily take with them whatever their circumstances and transport wherever they chose. They placed a high value on comradeship, and the man who was believed to have the greatest number of dependants and companions about him was the most feared and the most powerful member of the tribe.
The Celts, or (as the Romans liked to call them) the Gauls, were usually tall, well-built, and blond. They wore their hair long, whitening and stiffening it by frequent washing in limewater. They then pulled it back over the head so that the general effect was of a horse’s mane. They let their mustaches grow over their lips so that “when drinking the beverage passes, as it were, through a kind of strainer.” It is reported that male homosexuality was very common, and that men particularly liked to have two boys at a time in bed with them: “Young men offer themselves to strangers and are insulted if the offer is refused.” Women, too, enjoyed considerable sexual freedom, and were entitled to divorce husbands who failed to perform their marital duties. Unlike Greek or Roman women, they played a respected part in public life, acting as ambassadors and, on occasion, fighting in battles.
The Celts were undisciplined, gorged themselves on food and drink, and were always quarreling with one another. Politically they seemed to be fickle and inconsistent; they found it difficult to take a long-term view and stick to it.
It is hard to know how much weight to place on these accounts, for we have no counterbalancing records from the Celts themselves. Taken as a whole, the portrait of a race of noble savages is coherent, but we must not forget that it reflects the fears of the observer as much as it does the quality of life as experienced by a Celt. It is telling that the Greco-Roman authors pay no attention whatsoever to the extraordinary skill and beauty of Celtic metalwork and crafts.
What is certainly the case is that the Celts were fine warriors and knew how to frighten an enemy army out of its wits. Completely fearless, they rushed naked into battle, with their long hair streaming and strange war cries, accompanied by harsh trumpet blasts. Their cavalry rode with iron horseshoes, a military innovation, and the infantry carried finely tempered slashing broadswords. The Celts were able to muster very large forces and were hard to defeat. The news of their imminent arrival in central Italy was seen, rightly, as an emergency order.
Myriad warriors and even greater numbers of women and children arrived before Clusium, an important Etruscan city and once Lars Porsenna’s base. A foolish story is told that they were tempted there with a promise of Clusium’s large supplies of wine, and that, responding to an appeal from the city, the Romans sent some ambassadors, who met and remonstrated unsuccessfully with the Celtic king, Brennus. The ambassadors then fought alongside the army of Clusium in a vain attempt to repulse the Celts. This broke the principle of diplomatic neutrality, and infuriated Brennus, who ordered a retaliatory march on Rome, only eighty miles away.
What really seems to have happened is that Brennus led a band of marauders intent on plunder, not a people in search of Lebensraum. It is very possible that they were in the pay of the turannos of Syracuse, Dionysius, whose principal aim in these years was to undermine Rome’s ally, the Etruscan trading entrepôt of Caere, and the Greek cities of Magna Graecia. If that was so, the Celts were passing through on their way to southern Italy.
The Romans may have sent an advance force north to discover the truth behind the reports of a Celtic advance, but what is certain is that a hastily assembled Roman army confronted the invaders in a great battle at the little river Allia, a tributary of the Tiber. The numbers on each side are uncertain, but perhaps two legions, or about ten thousand Romans faced thirty thousand Celts. To avoid being outflanked, the Roman commander stretched his line out, but too thinly. Presumably, the well-to-do heavily armed legionaries were posted in the center, with the poorer citizens as light-armed troops on each wing. The center could not hold, fractured, and gave way.
It should have been a rout with high casualties, but Brennus had expected a larger enemy army. Suspecting an ambush, he held his men back. Many Romans were able to get away, and a good number escaped to nearby Veii, whose citadel was eminently defensible.
However, the way to Rome lay open.
LIVY DESCRIBES WHAT happened next in one of his great set pieces. It was a mark either of overconfidence or carelessness or both that Rome was not encircled by a protective wall. Earthen ramparts and hills were deemed a sufficient defense. Even worse, most of the army was either dead or cowering in the ruins of Veii. The city was undefended. There was nothing to stop Brennus from marching in and giving the Romans the treatment they had meted out to the people of Veii.
The Celts could hardly believe their eyes and, once again, feared a trap. They watched and waited until evening fell. Inside the beleaguered city, the most was made of a night’s reprieve. The handful of remaining troops took up position on the Capitol, where they should be able to hold out indefinitely. Civilians were allowed to take refuge there, too, but many others, especially of the poorer sort, poured out of the city gates across the wooden bridge, the Pons Sublicius, to the Janiculum Hill and vanished into the countryside. Vesta was goddess of the civic hearth and guarantor of Rome’s permanence. Her priestesses, who were vowed to chastity, the Vestal Virgins, debated what to do with the sacred emblems. It was decided to bury those that could not be moved and to travel with the remainder to the friendly Etruscan city of Caere. The Vestal Virgins’ main task was to tend the goddess’s eternal flame, and presumably they took it with them in the shape of a torch or a brazier. Abandoning their native land, they set off on foot but were given a lift by a patriotic carter. Rome was dead.
