From Narbonne, the Romans established the province of Transalpine Gaul, later called Gallia Narbonensis. Archaeological records attesting to his rule show up in coinage found in former Transalpine Gaul. After his consulship, Caesar gained control of the provinces of Illyricum, Cisalpine, and Transalpine Gaul. Transalpine Gaul (southern France) was added later. At the same time other types of interregional and transalpine exchange were growing in significance. He was a praetor in 46 and governor of Transalpine Gaul in 45. He introduced them to the high society of transalpine libertinage. Eska sees Cisalpine Gaulish as more akin to Lepontic than to Transalpine Gaulish.
