This trial was, as has been said, a "causa publica," a criminal accusation of such importance as to demand that it should be tried before a full bench of judges. Of these the number would be uncertain, but they were probably above fifty. The Prætor of the day--the Prætor to whom by lot had fallen for that year that peculiar duty--presided, and the judges all sat round him. Their duty seems to have consisted in listening to the pleadings, and then in voting. Each judge could vote[74] "guilty," "acquitted," or "not proven," as they do in Scotland. They were, in fact, jurymen rather than judges. It does not seem that any amount of legal lore was looked for specially in the judges, who at different periods had been taken from various orders of the citizens, but who at this moment, by a special law enacted by Sulla, were selected only from the Senators. We have ample evidence that at this period the judges in Rome were most corrupt. They were tainted by a double corruption: that of standing by their order instead of standing by the public--each man among them feeling that his turn to be accused might come--and that also of taking direct bribes. Cicero on various occasions--on this, for instance, and notably in the trial of Verres, to which we shall come soon--felt very strongly that his only means of getting a true verdict from the majority of judges was to frighten them into temporary honesty by the magnitude of the occasion. If a trial could be slurred through with indifferent advocates, with nothing to create public notice, with no efforts of genius to attract admiration, and a large attendance and consequent sympathy the judgment would, as a matter of course, be bought. In such a case as this of Sextus Roscius, the poor wretch would be condemned, sewed up in his bag, and thrown into the sea, a portion of the plunder would be divided among the judges, and nothing further would be said about it. But if an orator could achieve for himself such a reputation that the world would come and listen to him, if he could so speak that Rome should be made to talk about the trial, then might the judges be frightened into a true verdict. It may be understood, therefore, of what importance it was to obtain the services of a Cicero, or of a Hortensius, who was unrivalled at the Roman bar when Cicero began to plead.
