The Gauls at this time were besieging Clusium, a Tuscan city. The Clusinians sent to the Romans for succor desiring them to interpose with the barbarians by letters and ambassadors. There were sent three of the family of the Fabii, persons of high rank and distinction in the city. The Gauls received them courteously, from respect to the name of Rome, and, giving over the assault which was then making upon the walls, came to conference with them; when the ambassadors asking what injury they had received of the Clusinians that they thus invaded their city, Brennus, king of the Gauls, laughed and made answer, "The Clusinians do us injury, in that, being able only to till a small parcel of ground, they must needs possess a great territory, and will not yield any part to us who are strangers, many in number, and poor. In the same nature, O Romans, formerly the Albans, Fidenates, and Ardeates, and now lately the Veientines and Capenates, and many of the Faliscans and Volscians, did you injury; upon whom ye make war if they do not yield you part of what they possess, make slaves of them, waste and spoil their country, and ruin their cities; neither in so doing are cruel or unjust, but follow that most ancient of all laws, which gives the possessions of the feeble to the strong; which begins with God and ends in the beasts; since all these, by nature, seek, the stronger to have advantage over the weaker. Cease, therefore, to pity the Clusinians whom we besiege, lest ye teach the Gauls to be kind and compassionate to those that are oppressed by you." By this answer the Romans, perceiving that Brennus was not to be treated with, went into Clusium, and encouraged and stirred up the inhabitants to make a sally with them upon the barbarians, which they did either to try their strength or to show their own. The sally being made, and the fight growing hot about the walls, one of the Fabii, Quintus Ambustus, being well mounted, and setting spurs to his horse, made full against a Gaul, a man of huge bulk and stature, whom he saw riding out at a distance from the rest. At the first he was not recognized, through the quickness of the conflict and the glittering of his armor, that precluded any view of him; but when he had overthrown the Gaul, and was going to gather the spoils, Brennus knew him; and, invoking the gods to be witnesses, that, contrary to the known and common law of nations, which is holily observed by all mankind, he who had come as an ambassador had now engaged in hostility against him, he drew off his men, and, bidding Clusium farewell, led his army directly to Rome. But not wishing that it should look as if they took advantage of that injury, and were ready to embrace any occasion of quarrel, he sent a herald to demand the man in punishment, and in the meantime marched leisurely on.
