Aruns before he died. When the son became a young man, he fell in love with the wife of Aruns and seduced her. The grieving Aruns went to Gaul to sell wine, olives, and figs. The Gauls had never seen such products and asked Aruns where they were produced. He replied that they came from a large and fertile land, inhabited by only a few people who were not good fighters. He advised them to drive the people out of their land and enjoy the fruit as their own. He persuaded them to come to Italy, go to Clusium, and make war. Dionysius' account presumes that those Gauls had not invaded Italy and were in Gaul. When Quintus Fabius, one of the Roman ambassadors, killed a Gallic leader, they wanted the brothers to be handed over to them to pay the penalty for the men they had killed. When the ambassadors of the Senones arrived in Rome and demanded the three Fabii brothers be handed over to them, the Senate was pressured by favouritism not to express opinions against the powerful Fabia family. To avoid being blamed for a possible defeat if the Gauls attacked, they referred the matter to the people. Livy wrote that "those whose punishment they were asked to decide were elected military tribunes with consular powers [heads of state] for the coming year." The Gauls were enraged that those who had violated the law of nations had been honoured and marched on Rome, 130 km (81 mi) from Clusium. Livy wrote that "in response to the tumult caused by their swift advance, terrified cities rushed to arms and the country folk fled, but the Gauls signified by their shouts wherever they went that their destination was Rome." Size of belligerent forces The number of fighters involved in the battle is not known for sure. Plutarch writes that the Romans were not outnumbered and had 40,000 men but that most were untrained and unaccustomed to weapons. Dionysius of Halicarnassus writes that the Romans had four well-trained legions and a levy of untrained citizens that was larger in number. That would give a rough figure of some 35,000. Diodorus Siculus writes that the Romans had 24,000 men. Livy gives no figures. The modern historians Cary and Scullard estimate that the Romans had 15,000 men and the Gauls 30,000 to 70,000. Peter Berresford Ellis gives an estimate of a
