Strabo Geography 4.1.12

[12] The main part of the country on the other side of the Rhone is inhabited by the Volcae, surnamed Arecomisci. Their naval station is Narbonne, which may justly be called the emporium of all Gaul, as it far surpasses every other in the multitude of those who resort ¹ to it. The Volcae border on tile Rhone, the Salyes and Cavari being opposite to them on tile other side of the river. However, the name of the Cavari has so obtained, that all the barbarians inhabiting near now go by that designation; nay, even those who are no longer barbarians, but follow the Roman customs, both in their speech and mode of life, and some of those even who have adopted the Roman polity. Between the Arecomisci and the Pyrenees there are some other small and insignificant nations. Nemausus ² is the metropolis of the Arecomisci; though far inferior to Narbonne both as to its commerce, and the number of foreigners attracted thither, it surpasses that city in the number of its citizens; for it has under its dominion four and twenty different villages all well inhabited, and by the same people, who pay tribute; it likewise enjoys the rights of the Latin towns, so that in Nemausus you meet with Roman citizens who have obtained the honours of the aedile and quaestorship, wherefore this nation is not subject to the orders issued by the praetors from Rome. The city is situated on the road from Iberia to Italy; this road is very good in the summer, but muddy and overflowed by the rivers during winter and spring. Some of these streams are crossed in ferry-boats, and others by means of bridges constructed either of wood or stone. The inundations which destroy the roads are caused by the winter torrents, which sometimes pour down from the Alps even in summer-time after the melting of the snows. To perform the route before mentioned, the shortest way is, as we have said, across the territory of the Vocontii direct to the Alps; the other, along the coast of Marseilles and Liguria, is longer, although it offers an easier passage into Italy, as the mountains are lower. Nemausus is about 100 stadia distant from the Rhone, situated opposite to the small town of Tarascon, and about 720 stadia from Narbonne. The Tectosages, ³ and certain others whom we shall mention afterwards, border on the range of the Cevennes, and inhabit its southern side as far as the promontory of the Volcae. Respecting all the others we will speak hereafter.
