He was well connected to the Augustan regime,[2] with his sister, Terentia, married to Gaius Maecenas, the prominent adviser and friend of Augustus and patron of the arts,[3] while his half-brother, Gaius Proculeius, was an intimate friend of Augustus during his rise to power.
[4] Augustus dispatched Murena to lead an expedition against the Salassi tribe of the Aosta Valley region in the northwestern Alps in 25 BC.
[5] The Salassi had proved troublesome to Roman armies using the Great St Bernard pass, which, as the shortest route from Italy to the Upper Rhine river, had become strategically vital to the Romans since the completion of Julius Caesar's conquest of Gaul in 51 BC.
[6] In 24 BC, Murena established a Roman colony of 3,000 settlers in the heart of Salassi country - Augusta Praetoria Salassorum (Aosta, Italy).
[7] Murena was nominated to be Consul, with Augustus, for the year 23 BC, but died shortly before his term in office began.
