Lucius Licinius Murena was son and namesake of Lucius Licinius Murena who had fought in the Second Mithridatic War. He began his public career as quaestor in c. 75 BC. When the Third Mithridatic War began, in 73 BC, Murena was appointed legatus for, Lucius Licinius Lucullus, the proconsul in charge of the Roman war effort in the east and a fellow Licinius. Murena served in the East for several years; he had the command of one of Lucullus's legions, and in 72 BC Lucullus even entrusted him with the siege ofAmisus, a major Pontic city. In 65 BC, Murena was urban praetor and made himself popular by the magnificence of the games he provided. After his praetorship, Murena was the governor of Gallia Transalpina in 64 BC and part of 63 BC. On his way there he levied some troops in Umbria. Cicero said that "he republic enabled him to display his liberality, which he did so effectually as to engage in his interest many tribes which are connected with the municipalities of that district ." He returned to Rome from Gaul before the end of his term to stand for the consulship for 62 BC and left his brother, Gaius Murena, in charge of the province as his deputy. Cicero said that his "conduct in his province procured him the affection of many influential men, and a great accession of reputation" and that "he contrived by his equity and diligence to enable many of our citizens to recover debts which they had entirely despaired of."” In 63 BC Cicero managed to have Murena elected as one of the consuls for 62 BC instead of Lucius Sergius Catilina. However, before entering office he was accused of electoral bribery by Servius Sulpicius Rufus, whom he had defeated in the election, even though he was a famous jurist. The prosecution case was presented by Marcus Porcius Cato the younger. According to Plutarch, Cato heard that there had been electoral bribery and swore that he would prosecute the briber. He did not pursue Decimus Junius Silanus, Murena's consular colleague, because he was the husband of his sister Servilia. He persecuted Lucius Murena. Murena appointed a man to keep Cato under observation as there was a law according to which the defendant could do this so that there could be no secret about the evidence gathered by the prosecutor. However, this man saw Cato’s probity and told Cato that if on a given day he told him that he was not pursuing the case, he would take his word for it and go away. Cicero, the consul and Murena's advocate, took advantage of Cato's like of stoic philosophers to joke about their paradoxes. Cato said that he was amusing. Cicero, too, mentioned this episode. Murena was defended by Marcus Licinius Crassus, Quintus Hortensius, and Sulpicius' friend Cicero and was acquitted. It is possible, however, that Murena was in fact guilty. Much of our information about Murena's life and career comes from the contents of Cicero's speech. In the trial Murena was reproached for having adorned the triumph of his father with military gifts and sharing his triumph with him and was accused to have lived in luxury while he was on the military campaign. With regard to the triumph, Cicero argued that this was legitimate because he had served in the war under the command of his father. He added that the fact that he served in a war left no room for speaking ill of him. Murena was also accused of being a dancer, which characterised him as a person of less dignity. Cicero dismissed the relevance of this. He also dismissed the suggestion that the dignity of Sulpicius’ status was higher than that of Murena and made favourable points in regard to Murena’s. He also argued that Murena’s electoral success was also due to the return of the soldiers from the war, who remembered his largesse when he was serving with them. During his consulship, Murena and Decimus Junius Silanus, his consular colleague, passed a law laws should be promulgated a trinundium before they were proposed to the comitialeges saturae, that is, statutes dealing with heterogeneous subject matter, were forbidden. Thus, a single statute could not be a collection of unrelated measures. It further enacted that, in order to prevent forgery, a copy of every proposed statute should be deposited before witnesses in the aerarium before it was put to the vote of the popular assembly.
