 They are mentioned as "Vocontiorum" by Caesar (mid-1st c. BC), Livy (late 1st c. BC), Pliny (1st c. AD) and Pomponius Mela (mid-1st c. AD), as "Ouokóntioi" (Οὐοκόντιοι) and "Ouokontíōn" (Οὐοκοντίων) by Strabo (early 1st c. AD), as "Ou̓okóntioi" (Οὐοκόντιοι) by Ptolemy (2nd c. AD).and as "Bocontii" on the "Tabula Peutingeriana".The name "Vocontii" probably stems from Gaulish "Uo-conti" ('twenty', perhaps 'twenty-hundred'), after a Gaulish custom of including numbers in tribal names (see "Tri-corii, Petru-corii", the 'three-', 'four-tribes').
