M. Tullius Cicero Pro Fonteio 13

[13] There is in the same province Narbo Martius , ¹ a colony of our citizens, set up as a watch-tower of the Roman people, and opposed as a bulwark to the attacks of those very natives. There is also the city of Massilia , which I have already mentioned, a city of most gallant and faithful allies, who have made amends to the Roman people for the dangers to which they have been exposed in the Gallic wars, by their service and assistance; there is, besides, a large number of Roman citizens, and most honourable men. 6
  Of this province, consisting of this variety of people, Marcus Fonteius, as I have said, was governor. Those who were enemies, he subdued; those who had lately been so, he compelled to depart from the lands of which they had been deprived by the senate. From the rest, who had been often conquered in great wars, on purpose that they might be rendered obedient for ever to the Roman people, he exacted large troops of cavalry to serve in those wars which at that time were being carried on all over the world by the Roman people, and large sums of money for their pay, and a great quantity of corn to support our armies in the Spanish war.
