the impending attack.  On the southern border of the canton of the Allobroges at the confluence of the Isere with the Rhone, on the 8th of August 633, the battle was fought which decided the mastery of southern Gaul.  King Betuitus, when he saw the innumerable hosts of the dependent clans marching over to him on the bridge of boats thrown across the Rhone and the Romans who had not a third of their numbers forming in array against them, is said to have exclaimed that there were not enough of the latter to satisfy the dogs of the Celtic army.  Nevertheless Maximus, a grandson of the victor of Pydna, achieved a decisive victory, which, as the bridge of boats broke down under the mass of the fugitives, ended in the destruction of the greater part of the Arvernian army.  The Allobroges, to whom the king of the Arverni declared himself unable to render further assistance, and whom he advised to make their peace with Maximus, submitted to the consul; whereupon the latter, thenceforth called Allobrogicus, returned to Italy and left to Ahenobarbus the no longer distant termination of the Arvernian war.  Ahenobarbus, personally exasperated at king Betuitus because he had induced the Allobroges to surrender to Maximus and not to him, possessed himself treacherously of the person of the king and sent him to Rome, where the senate, although disapproving the breach of fidelity, not only kept the men betrayed, but gave orders that his son, Congonnetiacus, should likewise be sent to Rome.  This seems to have been the reason why the Arvernian war, already almost at an end, once more broke out, and a second appeal to arms took place at Vindalium (above Avignon) at the confluence of the Sorgue with the Rhone.  The result was not different from that of the first:  on this occasion it was chiefly the African elephants that scattered the Celtic army.  Thereupon the Arverni submitted to peace, and tranquillity was re-established in the land of the Celts.(3)

Province of Narbo

The result of these military operations was the institution of a new Roman province between the maritime Alps and the Pyrenees.  All the tribes between the Alps and the Rhone became dependent on the Romans and, so far as they did not pay tribute to Massilia, presumably became now tributary to Rome.  In the country between the Rhone and the Pyrenees the Arverni retained freedom and were not bound to pay tribute to the Romans; but they had to cede to Rome the most southerly portion of their direct or indirect territory-the district to the south of the Cevennes as far as the Mediterranean, and the upper course of the Garonne as far as Tolosa (Toulouse).  As the primary object of these occupations was the establishment of a land communication between Italy and Spain, arrangements were made immediately thereafter for the construction of the road along the coast.  For this purpose a belt of coast from the Alps to the Rhone, from 1 to 1 3/4 of a mile in breadth, was handed over to the Massiliots, who already had a series of maritime stations along this coast, with the obligation of keeping the road in proper condition; while from the Rhone to the Pyrenees the Romans themselves laid out a military highway, which obtained from its originator Ahenobarbus the name of the -Via Domitia-.
