Auscii
The Auscii or Ausci were an Aquitani tribe dwelling around present-day Auch during the Iron Age.
Alongside the Tarbelli, they were one of the most powerful peoples of Aquitania.
Name
They are mentioned as Ausci by Caesar, Pliny and Pomponius Mela, and as Au̓skíois by Strabo.The ethnonym Auscii may be related to the prefix eusk-, meaning 'Basque' in the Basque language.
The city of Auch, attested as civitas Auscius in the early 4th century AD, is named after the tribe.
Geography
Their territory was located north of the Onobrisates, west of the Cambolectri and Volcae Tectosages, south of the Lactorates, west of the Atures.The chief town of the Auscii was known as Elimberrum, whose name can be compared to the Basque ili-berri.
