They are mentioned as Ausuciatium on an inscription dated to the early 1st millennium AD and found in Ossuccio (Ausucum).[1][2]
The ethnonymAusuciates may be derived from the Gaulish root aus(i)- ('ear'), and possibly translated as 'those having big ears'. It could be compared with the Old Irishóach ('with big ears'), from an earlier *ausākos.[3][2] Alternatively, it may be derived from a hypothetical deity named *Ausucos ('The Golden One'), from the root *aus- ('gold'). The place-name Ausucum has been translated as the 'domain of *Ausucos'.[4][5]
