There is also the question of what the Senones were doing in central Italy. Diodorus Siculus wrote that the Senones were "distressed and eager to move" because they had settled to a place (the ager Gallicus) that was too hot. They armed their younger men and sent them out to seek a territory where they might settle. Therefore, they invaded Etruria, the 30,000 sacked the territory of Clusium. However, Cornell finds that to be unconvincing. Throughout the story, the Senones appear to be a warrior band. There is no mention in any of the accounts of wives and children, who would have been present if the Gauls had been a migrating people in search for land. Cornell thinks that they were mercenaries. A few months after the sack of Rome, Dionysius I of Syracuse, the tyrant of the Greek city of Syracuse, in Sicily, hired Gallic mercenaries for a war in the south of Italy. It may well be that was why the Senones were on their way to the south. The story of their defeat on their way back from the south seems to fit with that hypothesis. It could also be that the Senones went to Clusium because they had been hired by one of two political factions at loggerheads to intervene in political struggles in the city, rather than the romanticised story of Aruns's revenge for his wife.
