A similar character of financial speculation marks the war, which was waged by the Romans under the consul Appius Claudius in 611 against the Salassi respecting the gold mines and gold washings of Victumulae (in the district of Vercelli and Bard and in the whole valley of the Dorea Baltea). The great extent of these washings, which deprived the inhabitants of the country lying lower down of water for their fields, first gave rise to an attempt at mediation and then to the armed intervention of the Romans. The war, although the Romans began it like all the other wars of this period with a defeat, led at last to the subjugation of the Salassi, and the cession of the gold district to the Roman treasury. Some forty years afterwards (654) the colony of Eporedia (Ivrea) was instituted on the territory thus gained, chiefly doubtless with a view to command the western, as Aquileia commanded the eastern, passage of the Alps.
The Arverni
These Alpine wars first assumed a more serious character, when Marcus Fulvius Flaccus, the faithful ally of Gaius Gracchus, took the chief command in this quarter as consul in 629. He was the first to enter on the career of Transalpine conquest. In the much-divided Celtic nation at this period the canton of the Bituriges had lost its real hegemony and retained merely an honorary presidency, and the actually leading canton in the region from the Pyrenees to the Rhine and from the Mediterranean to the Western Ocean was that of the Arverni[2]; so that the statement seems not quite an exaggeration, that it could bring into the field as many as 180,000 men. With them the Haedui (about Autun) carried on an unequal rivalry for the hegemony; while in north-eastern Gaul the kings of the Suessiones (about Soissons) united under their protectorate the league of the Belgic tribes extending as far as Britain. Greek travellers of that period had much to tell of the magnificent state maintained by Luerius, king of the Arvernians - how, surrounded by his brilliant train of clansmen, his huntsmen with their pack of hounds in leash and his band of wandering minstrels, he travelled in a silver-mounted chariot through the towns of his kingdom, scattering the gold with a full hand among the multitude, and gladdening above all the heart of the minstrel with the glittering shower. The descriptions of the open table which he kept in an enclosure of 1500 double paces square, and to which every one who came in the way was invited, vividly remind us of the marriage table of Camacho. In fact, the numerous Arvernian gold coins of this period still extant show that the canton of the Arvernians had attained to extraordinary wealth and a comparatively high standard of civilization.
The attack of Flaccus, however, fell in the first instance not on the Arverni, but on the smaller tribes in the district between the Alps and the Rhone, where the original Ligurian inhabitants had become mixed with subsequent arrivals of Celtic bands, and there had arisen a Celto-Ligurian population that may in this respect be compared to the Celtiberian. He fought (629, 630) with success against the Salyes or Salluvii in the region of Aix and in the valley of the Durance, and against their northern neighbours the Vocontii (in the departments of Vaucluse and Drome); and so did his successor Gaius Sextius Calvinus (631, 632) against the Allobroges, a powerful Celtic clan in the rich valley of the Isere, which had come at the request of the fugitive king of the Salyes, Tutomotulus, to help him to reconquer his land, but was defeated in the district of Aix. When the Allobroges nevertheless refused to surrender the king of the Salyes, Gnaeus Domitius Ahenobarbus, the successor of Calvinus, penetrated into their own territory (632).
Up to this period the leading Celtic tribe had been spectators of the encroachments of their Italian neighbours; the Arvernian king Betuitus, son of the Luerius already mentioned, seemed not much inclined to enter on a dangerous war for the sake of the loose relation of clientship in which the eastern cantons might stand to him. But when the Romans showed signs of attacking the Allobroges in their own territory, he offered his mediation, the rejection of which was followed by his taking the field with all his forces to help the Allobroges; whereas the Haedui embraced the side of the Romans. On receiving accounts of the rising of the Arverni, the Romans sent the consul of 633, Quintus Fabius Maximus, to meet in concert with Ahenobarbus 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].
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.
2. In Auvergne. Their capital, Nemetum or Nemossus, lay not far from Clermont.
3. The battle at Vindalium is placed by the epitomator of Livy and by Orosius before that on the Isara; but the reverse order is supported by Floras and Strabo (iv. 191), and is confirmed partly by the circumstance that Maximus, according to the epitome of Livy and Pliny, H. N. vii. 50, conquered the Gauls when consul, partly and especially by the Capitoline Fasti, according to which Maximus not only triumphed before Ahenobarbus, but the former triumphed over the Allobroges and the king of the Arverni, the latter only over the Arverni. It is clear that the battle with the Allobroges and Arverni must have taken place earlier than that with the Arverni alone.
