M. Tullius Cicero Cum Senatui Gratias Egit 25

[25]
  What could I leave to my posterity more glorious than the fact, that the senate had declared its judgment that any citizen who did not defend me, did not desire the safety of the republic? Therefore your authority, and the preeminent dignity of the consul, had this great effect, that every one thought that he was committing a shameful crime if he did not come to that summons. And this same consul, when that incredible multitude, when Italy itself I might almost say, had come to Rome, summoned you repeatedly to the Capitol; and at that time you had an opportunity of seeing what great power excellence of natural disposition and true nobleness have. For Quintus Metellus, himself an enemy of mine, and a brother of an enemy of mine, as soon as he was assured of your inclinations, laid aside his own private dislike to me and allowed Publius Servilius, a most illustrious man, and also a most virtuous one, and a most intimate friend of my own, to recall him, by what I may call the divine influence of his authority and eloquence, to the exploits and virtues of his race and of their common family, so as to take to his counsels his brother, in the shades below, the companion of my fortunes, and all the Metelli, those most admirable citizens, summoning them as it were from Acheron; and among them the great conqueror of Numidia, whose departure from his country formerly seemed grievous to all the citizens, but scarcely even vexatious to himself.
