Of those orations of Cicero which have entirely perished, the greatest loss has been sustained by the disappearance of the defence of Cornelius, who was accused of practices against the state during his tribuneship. This speech, which was divided into two great parts, was continued for four successive days, in presence of an immense concourse of people, who testified their admiration of its bright eloquence by repeated applause(332). The orator himself frequently refers to it as among the most finished of his compositions(333); and the old critics cite it as an example of genuine eloquence. "Not merely," says Quintilian, "with strong, but with shining armour did Cicero contend in the cause of Cornelius." We have also to lament the loss of the oration for C. Piso, accused of oppression in his government--of the farewell discourse delivered to the Sicilians, (_Quum Quæstor Lilybæo discederet_,) in which he gave them an account of his administration, and promised them his protection at Rome--of the invective pronounced in the Senate against Metellus, in answer to a harangue which that Tribune had delivered to the people concerning Cicero's conduct, in putting the confederates of Catiline to death without trial; and, finally, of the celebrated speech _De Proscriptorum Liberis_, in which, on political grounds, he opposed, while admitting their justice, the claims of the children of those whom Sylla had proscribed and disqualified from holding any honours in the state, and who now applied to be relieved from their disabilities. The success which he obtained in resisting this demand, is described in strong terms by Pliny: "Te orante, proscriptorum liberos honores petere puduit(334)." A speech which is now lost, and which, though afterwards reduced to writing, must have been delivered extempore, afforded another strong example of the persuasiveness of his eloquence. The appearance of the Tribune, Roscius Otho, who had set apart seats for the knights at the public spectacles, having one day occasioned a disturbance at the theatre, Cicero, on being informed of the tumult, hastened to the spot, and, calling out the people to the Temple of Bellona, he so calmed them by the magic of his eloquence, that, returning immediately to the theatre, they clapped their hands in honour of Otho, and vied with the knights in giving him demonstrations of respect(335). One topic which he touched on in this oration, and the only one of which we have any hint from antiquity, was the rioters' want of taste, in creating a tumult, while Roscius was performing on the stage(336). This speech, the orations against the Agrarian law, and that _De Proscriptorum Liberis_, have long been cited as the strongest examples of the power of eloquence over the passions of mankind: And it is difficult to say, whether the highest praise be due to the orator, who could persuade, or to the people, who could be thus induced to relinquish the most tempting expectations of property and honours, and the full enjoyment of their favourite amusements.
