At that time, it was settled by an Aquitanian tribe known to the Romans as the Ausci. Their name for the town was Climberrum or Elimberris. This has been tentatively etymologized from the Iberian iltir ("town, oppidum") and a cognate of the Basque berri ("new"), although another Iberian settlement in Granada recorded by the Romans as "Iliberi" probably had no contact with proto-Basque speaking peoples. Following their conquest, the Romans renamed the town Augusta Auscorum or Ausciorum ("Augusta of the Ausci"). Augusta Auscorum was one of the twelve civitates of the province of Novempopulana (Gascony) and became the provincial capital after the 409 destruction of Eauze by the Vandals.
