They are mentioned as CadurcusbyCaesar (mid-1st c. BC),[1]Kadou͂rkoi (Καδοῦρκοι) by Strabo (early 1st c. AD) and Ptolemy (2nd c. AD),[2] and as CadurcibyPliny (1st c. AD).[3][4]
The etymology of the ethnonymCadurci remains uncertain. Pierre-Yves Lambert has proposed to interpret it as a haplology (loss of syllabe) for the GaulishcompoundCatu-turci ('battle-boars'), formed with the root catu- ('combat, battle') attached to the plural of turcos ('wild boar').[5][6]
The city of Cahors, attested ca. 400 AD as civitas Cadurcorum ('civitas of the Cadurci', Cauricio in 1200, Caurs 1279), and the region of Quercy, attested in 565 AD as Cadurcinus (pagus Catorcinus in 628, Caercino in 1095, with Latin suffix -inus), are named after the Gallic tribe.[7]
