ALLOBROGES cal-lob're-gas), 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, correspond ing to the modern Dauphine 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 (later Gratianopolis, whence Grenoble). The Allobroges first occur in history as taking part with Hannibal in the invasion of Italy. After the sub jugation of the Salluvii (Salyes) by the Romans in 123 B.C., the Allobroges were attacked and finally defeated (12i B.c.) at the junction of the Rhodanus and Isara by Q. Fabius Maximus (afterwards Allobrogicus). But they still remained hostile to Rome, as is shown by the conduct of their ambassadors in the Catilinarian conspiracy (63 B.C. ; see CATILINE).
