The whole of Gaul that is comprehended under the one general name of Comata, is divided into three groups of people, which are more especially kept distinct from each other by the following rivers. From the Scaldis to the Sequana it is Belgica; from the Sequana to the Garumna it is Celtica or Lugdunensis; and from the Garumna to the promontory of the Pyrenæan range it is Aquitanica, formerly called Aremorica.
^"Celtae" or "Celts" is the name used by the inhabitants of the Celtica region in their own language. "Galli" or "Gauls" was the Roman name given by Julius Caesar to the inhabitants of the Celtica region of Gaul in his narrative "Commentaries on the Gallic War".
^Caesar, Julius. "Commentarii de bello Gallico". "Gallia est omnis divisa in partes tres, quarum unam incolunt Belgae, aliam Aquitani, tertiam qui ipsorum lingua Celtae, nostra Galli appellantur."
^Pliny the Elder. "Naturalis Historia (4.17 / 4.31)". "Gallia omnis Comata uno nomine appellata in tria populorum genera dividitur, amnibus maxime distincta. a Scalde ad Sequanam Belgica, ab eo ad Garunnam Celtica eademque Lugdunensis, inde ad Pyrenaei montis excursum Aquitanica, Aremorica antea dicta. Universam oram."
