Brennus (leader of the Senones)

[citation needed] The Senones were a Gaulish tribe originating from the part of France at present known as Seine-et-Marne, Loiret, and Yonne, who had expanded to occupy northern Italy.

[1] At around 400 BC, a branch of the Senones made their way over the Alps and, having driven out the Umbrians, settled on the east coast of Italy from Ariminum to Ancona, in the so-called Ager Gallicus, and founded the town of Sena Gallica (current Senigallia), which became their capital.

According to Livy, during a dispute over the weights used to measure the gold (the Gauls had brought their own, heavier-than-standard), Brennus threw his sword onto the scales and uttered the famous words "Vae victis!

[4] One version of the story states that the argument about the weights had so delayed matters that the exiled dictator Marcus Furius Camillus had extra time to muster an army, return to Rome and expel the Gauls, saving both the city and the treasury, and telling Brennus, "Non auro, sed ferro, recuperanda est patria", which translates to "not by gold, but by iron, is the nation to be recovered".

According to Plutarch, following initial combat through Rome's streets, the Gauls were first ejected from the city, then utterly annihilated in a regular engagement eight miles outside of town on the road to Gabii.

Silius Italicus claims that Hannibal's Boii cavalrymen were led by a descendant of Brennus named Crixus, who fell in the Battle of Ticinus.
