In pre-Roman Gaul the Belgic tribe of the Veliocasses or Velocasses controlled a large area in the lower Seine valley, which retains a trace of their name, as the Vexin, in 52 they raised 3000 men to support which son of Celtillus the Avernian, leader of the Gallic tribes?
Vercingetorix Vercingetorix was the son of Celtillus the Avernian, leader of the Gallic tribes. Vercingetorix came to power after his formal designation as chieftain of the Arverni at the oppidum Gergovia in 52 BC. He immediately established an alliance with other Gallic tribes, took command and combined all forces, and led them in the Celts' most significant revolt against Roman power. He won the Battle of Gergovia against Julius Caesar in which several thousands Romans and allies died and Caesar's Roman legions withdrew.
Lucius Petronius Taurus Volusianus Volusianus was a Roman citizen, apparently of equestrian origins, whose career in the Imperial Service in the mid-Third Century AD carried him from a relatively modest station in life to the highest public offices and senatorial status in a very few years. He may have secured his first appointments before the Licinian Dynasty - (Valerian and his son Gallienus) - acceded to the Empire in 253 AD, but it was in the course of their reign that his upward progress achieved an almost unprecedented momentum and the second factor seems to have been a consequence of the first. The nature of his relationship to the Licinii is uncertain, but it seems likely that a common origin in the Etruscan region of central Italy predisposed Gallienus at least in his favour and he seems to have been that prince's most trusted servant and adviser during the period of his sole reign - 260(?)-268 AD.
