Mamercus Aemilius Lepidus Livianus

Mamercus Aemilius Lepidus Livianus, Consul 77 BC and possibly Princeps Senatus was a well connected and influential figure in Late Republican politics. Brother of Marcus Livius Drusus (tribune) and son of Marcus Livius Drusus (censor), he was adopted into the Aemilii Lepidi. He married Cornelia Sulla, daughter of Lucius Cornelius Sulla, and may have been (the evidence is inconclusive) princeps senatus in the Sullan senate. He was consul in 77 BC, the year after Sulla's death.

Lepidus Livianus appears in Colleen McCullough's novel The Grass Crown (novel) and its sequels.

Biography

Livianus was a well connected and influential figure in Late Republican politics. A member of the aristocratic party, brother of the tribune Marcus Livius Drusus and son of Marcus Livius Drusus, he was adopted into the Aemilii Lepidi. His influence was such that he was able to intercede with Lucius Cornelius Sulla on the young Julius Caesar's behalf, getting Sulla to spare Caesar's life. He was also married to Cornelia Sulla, Sulla's daughter.

Around 91 BC he succeeded his brother Marcus Livius Drusus as one of the pontifices in the College of Pontiffs. He served with distinction in the Social War (91–88 BC), probably serving as legate under Quintus Caecilius Metellus Pius. He achieved some victories, most notably he was credited with killing the general of the Marsi, Quintus Poppaedius Silo, during the storming of Venusia.

Although having failed once to be elected praetor, he tried again, achieving the office by 81 BC. He ran for the office of consul in 77 BC, achieving it only after Gaius Scribonius Curio withdrew his candidature for that year in favor of Livianus. Although during his term as consul he commanded a considerable number of military forces, there is no evidence that he obtained a provincial command after his term was concluded.

Following his term as consul he was probably a promagistrate serving under Marcus Antonius Creticus in 74 BC, who had been given an extraordinary commission to clear the Mediterranean Sea of the Ligurian pirates. By 70 BC, he may have been Princeps Senatus, although the evidence is inconclusive. He was called as a hostile witness against Gaius Cornelius in 65 BC, as part of the events surrounding the First Catilinarian Conspiracy.
