M. Tullius Cicero Pro A. Cluentio 138

[138] From which that was easy to be understood which has been often said,—that as the sea, which by its own nature is tranquil, is often agitated and disturbed by the violence of the winds, so, too, the Roman people is, when left to itself, placable, but is easily roused by the language of seditious men, as by the most violent storm. 50
  There is also one other very great authority besides, which I had almost passed over in a shameful manner; for it is said to be my own. Attius read out of some oration or other, which he said was mine, a certain exhortation to the judges to judge honestly, and a certain mention of judicial decisions in other cases, which had not been approved of, and also of that very trial before Junius; just as if I had not said at the beginning of this defence, that had been a trial which had incurred great unpopularity; or as if, when I was discussing the discredit into which the courts of justice had fallen in some instances, I could possibly at that time pass over that one which was so notorious.
