Less common is the assumption of "Celticity" for European cultures deriving from Continental Celtic roots (Gauls or Celtiberians). These were either Romanised or Germanised much earlier, before the Early Middle Ages. Nevertheless, "Celtic" origins are many times implied for continental groups such as the Asturians, Galicians, Portuguese, Swiss, Northern Italians, Belgians and Austrians. The names of Belgium and Aquitaine hark back to "Gallia Belgica" and "Gallia Aquitania", respectively, in turn named for the Belgae and the Aquitani. The Latin name of the Swiss Confederacy, "Confoederatio Helvetica", harks back to the Helvetii, the name of Galicia to the Gallaeci and the Auvergne of France to the Averni.
