According to Dionysius of Halicarnassus, Lucumo was the king of the city. He assigned the guardianship of his son to 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.
