A member of the patriciangens Cornelia, the Lentuli were among the most haughty of the old Patrician families, with a long distinguished lineage that stretched back to the Sack of Rome in 387 BC. Lentulus Augur was an impoverished member of the family, and was only able to qualify for the Roman Senate as a result of a generous donation from the emperor Augustus. This in effect meant that he became a client of the emperor. He was used by Augustus to demonstrate the support of the ancient great houses for the system of the Principate, as well as his dedication to reviving the name and status of the old Roman nobility. With the emperor’s support, he was awarded the consulship in 14 BC. Lentulus was appointed as the Proconsular governor of Asia, where he served from 2 to 1 BC. Lentulus was also given the opportunity to pursue a military career, and he was appointed imperial legate of Illyricum sometime before 4 AD. It is believed that he was also the imperial legate in Moesia before 6 AD, where he fought across the Danube, winning an honorary triumph for his victories over the Getae. In 14 AD he was serving along the Danube under Germanicus as his Comes. The new emperor, Tiberius, had appointed him in the hope he would act as an advisor to Germanicus. His presence was resented by the Pannonian legions, who mutinied after the death of Augustus. They attacked him and he was only rescued through the intervention of Germanicus. He returned to Rome in 16 AD. When Marcus Scribonius Libo Drusus killed himself, he recommended in the Senate that members of the gens Scribonius were never again to bear the name Drusus. Then in 22 AD, while standing in for the absent pontifex maximus, he objected to the appointment of the incumbent flamen dialis, Servius Cornelius Lentulus Maluginensis as governor of Asia. That same year he proposed that the property inherited by Gaius Junius Silanus through his mother would not be confiscated as a result of Silanus’ conviction of extortion, to which Tiberius agreed. In 24 AD, he was accused of conspiring to murder Tiberius along with Vibius Serenus, Marcus Caecilius Cornutus and Lucius Seius Tubero. The emperor exonerated him of all charges. Tiberius declared that, “I am not worthy to live if Lentulus hates me as well.” Lentulus died in 25 AD, leaving his enormous fortune to Tiberius. Tacitus implied that this was a voluntary act; Suetonius, however, states that he committed suicide and was forced to leave his fortune to Tiberius. A wealthy man, his freedmen had reduced him to poverty before he was able to reclaim his wealth through the generosity of Augustus. He was given large coastal estates in Tarraconensis by Augustus, who was an absentee landholder. After his death, his lands went mostly to Tiberius, but some of his Spanish estates were obtained by the Vibii Serenii. Seneca described Lentulus as:
A barren mind, and a spirit no less feeble. He was the greatest of misers, but freer with coins than talk, so dire was his poverty of speech. He owed all his advancement to Augustus.
Tacitus had a much higher opinion of him, describing him as:
A man who bore his poverty with fortitude, and when he innocently acquired great wealth, he used it with great moderation.
