Augusta Auscorum
Augusta Auscorum (Auch), the chief town of the Ausci, a people of Aquitania. Augusta was originally Climberrum (Mela, 3.2), which seems to be a Basque name. Like many other Gallic towns named Augusta, it obtained this appellation under Augustus or some of his successors. It was on the road from Bordeaux to Toulouse. It appears in the Table under the name Eliberre; and in the Antonine Itin., on the route from Aginnum (Agen) to Lugdunum in Aquitania, under the name of Climberrum. Auch is the chief town of the department of Gers, and on the river Gers, a tributary of the Garonne. [AUSCI]
