M. Tullius Cicero Pro Fonteio 36

[36]
  Among other reasons, this, O judges, is a very great reason for his acquittal, to prevent any notable stain and disgrace from falling on our dominion, by news going to Gaul that the senate and knights of the Roman people gave their decisions in a criminal trial just as the Gauls pleased; being influenced not by their evidence, but by their threats. But in that case, if they attempt to make war upon us, we must summon up Caius Marius from the shades below, in order that he may be equal in war to that great man, that threatening and arrogant Induciomarus. Cnaeus Domitius and Quintus Maximus must be raised from the dead, that they may again subdue and crush the nation of the Allobroges and the other tribes by their arms; or, since that indeed is impossible, we must beg my friend Marcus Plaetorius to deter his new clients from making war, and to oppose by his entreaties their angry feelings and formidable violence; or, if he be not able to do so, we will ask Marcus Fabius, his junior counsel, to pacify the Allobroges, since among their tribe the name of Fabius is held in the highest honour, and induce them either to be willing to remain quiet, as defeated and conquered nations usually are, or else to make them understand that they are holding out to the Roman people not a terror of war, but a hope of triumph.
