Lucius Murena was one of the consuls elect; the other being Silanus, the brother-in-law of Cato. Cato, however, instigated Sulpicius, one of the most eminent lawyers in Rome, and a defeated competitor for the consulship, to prosecute Murena for bribery, under the new law passed by Cicero, (mentioned in the argument to the first oration against Catiline,) though he brought no charge against Silanus, who was as guilty as Murena, if there was any guilt at all. Murena had served as lieutenant to Lucullus in the Mithridatic war. Murena was defended by Crassus, Hortensius, and Cicero. We have neither of the speeches of his other advocates; and even the speech of Cicero is not in a perfect state. Murena was unanimously acquitted, partly perhaps from consideration of the argument which Cicero dwelt upon very earnestly, of what great importance it was, at such a perilous time, (for this oration was spoken in the interval between the flight of Catiline to the camp of Manlius, and the final detection and condemnation of the conspirators who remained behind,) to have a consul of tried bravery and military experience. It is remarkable that Sulpicius, the prosecutor, was a most intimate friend of Cicero, who had exerted all his influence to procure his election in this very contest for the consulship; and so also was Cato; nor did the opposition which Cicero made to them in this case cause any interruption to their intimacy, and we shall find, in the Philippics, Cicero exerting himself to procure public funeral honours for Sulpicius.
