Gallia Celtica

Gallia Celtica, Latin for Celtic Gaul, was a cultural region of ancient Gaul inhabited by Celts. It lay in what is now France, Switzerland, Luxembourg and the west bank of the Rhine River in Germany. Roman writers described Gaul as divided into three parts. Julius Caesar, in his Commentaries on the Gallic War, named Belgica, Aquitania and Celtica, saying that the Belgae lived in one, the Aquitani in another, and in the third lived the people who called themselves Celts in their own language and whom the Romans called Galli. Pliny the Elder gave a similar division by rivers: Belgica ran from the Scaldis to the Sequana, Celtica or Lugdunensis from the Sequana to the Garumna, and Aquitanica from the Garumna to the Pyrenees, an area formerly called Aremorica.
