70. And now at last the signal was given on both sides and the trumpet began to call to the conflict, and of that great host every man sought to do his part; but a few Romans, the noblest, and some Greeks, men who were present without taking part in the battle, now that the dreadful crisis was near, began to reflect upon the pass to which contentiousness and greed had brought the sovereign Roman state. [2] For with kindred arms, fraternal ranks, and common standards, the strong manhood and might of a single city in such numbers was turning its own hand against itself, showing how blind and frenzied a thing human nature is when passion reigns. For had they now been willing quietly to govern and enjoy what they had conquered, the greatest and best part of earth and sea was subject to them, and if they still desired to gratify their thirst for trophies and triumphs, they might have had their fill of wars with Parthians or Germans. [3] Besides, a great task still remained in the subjugation of Scythia and India, and here their greed would have had no inglorious excuse in the civilization of barbarous peoples. And what Scythian horse or Parthian archery or Indian wealth could have checked seventy thousand Romans coming up in arms under the leadership of Pompey and Caesar, whose names those nations had heard of long before that of Rome, so remote and various and savage were the peoples which they had attacked and conquered. [4] But now they were about to join battle with one another, nor were they moved even by a compassion for their own glory to spare their country, men who up to that day had been called invincible! For the family alliance which had been made between them, and the charms of Julia, and her marriage, were now seen to have been from the first suspicious and deceptive pledges of a partnership based on self-interest; there was no real friendship in it.
