“ ALLOBROGES (in Gr. usually Ἀλλόβριγες) , a Celtic tribe in the north of Gallia Narbonensis, inhabiting the low ground called the “island” between the Rhodanus, the Isara and the Graian Alps, corresponding to the modern Dauphiné and Savoy. If the name is rightly interpreted as meaning “aliens,” they would seem to have driven out the original inhabitants. Their chief towns were Vienna (Vienne) , Genava (Geneva) and Cularo (afterwards Gratianopolis, whence Grenoble) . The Allobroges first occur in history as taking part with Hannibal in the invasion of Italy. ”
