But such trials as that of Verres were much more like an impeachment before the House of Commons than a calm judicial inquiry. The men who would have to try a defendant of his class would be, in very few cases, honest and impartial weighers of the evidence. Their large number (varying from fifty to seventy) weakened the sense of individual responsibility, and laid them more open to the appeal of the advocates to their political passions. Most of them would come into court prejudiced in some degree by the interests of party; many would be hot partisans. Cicero, in his treatise on ‘Oratory’, explains clearly for the pleader’s guidance the nature of the tribunals to which he had to appeal. “Men are influenced in their verdicts much more by prejudice or favour, or greed of gain, or anger, or indignation, or pleasure, or hope or fear, or by misapprehension, or by some excitement of their feelings, than either by the facts of the case, or by established precedents, or by any rules or principles whatever either of law or equity”.
Verres was supported by some of the most powerful families at Rome. Peculation on the part of governors of provinces had become almost a recognised principle: many of those who held offices of state either had done, or were waiting their turn to do, much the same as the present defendant; and every effort had been made by his friends either to put off the trial indefinitely, or to turn it into a sham by procuring the appointment of a private friend and creature of his own as public prosecutor. On the other hand, the Sicilian families, whom he had wronged and outraged, had their share of influence also at Rome, and there was a growing impatience of the insolence and rapacity of the old governing houses, of whose worst qualities the ex-governor of Sicily was a fair type. There were many reasons which would lead Cicero to take up such a cause energetically. It was a great opening for him in what we may call his profession: his former connection with the government of Sicily gave him a personal interest in the cause of the province; and, above all, the prosecution of a state offender of such importance was a lift at once into the foremost ranks of political life. He spared no pains to get up his case thoroughly. He went all over the island collecting evidence; and his old popularity there did him good service in the work.
