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?
Veliocasses 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. According to Julius Caesar' "Commentary on the Gallic Wars" the Veliocasses participated in the tribal coalition of the Belgae that resisted the Romans in 57 BCE. In 52 they raised 3000 men to support Vercingetorix, and fought alongside the Bellovaci in the final rebellion against Roman hegemony.
Abrincatui The Abrincatui were a Gallic tribe (Plin. iv. 18), not mentioned by Julius Caesar, whose frontier was near the Curiosolites. Their town Ingena, called "Abrincatae" in the Notitia dignitatum, has given its name to the modern Avranches; and their territory would probably correspond to the division of Avranchin. The Abrincatui became a client tribe of the Venelli until the Roman occupation in BC 49, when they were separated.
