Consular Flavius Clemens

Titus Flavius Clemens was a Roman senator of the Flavian house who held the ordinary consulship in 95 and was put to death later that year by his cousin, the emperor Domitian. He was the son of Titus Flavius Sabinus, a former consul and prefect of the city of Rome, and therefore nephew of Vespasian and first cousin of the emperors Titus and Domitian. The Flavii had risen from municipal origins in the Sabine country to the imperial throne after the civil wars of 69; Clemens belonged to the collateral, senatorial branch of that family rather than to the reigning line.

He married Flavia Domitilla, a granddaughter of Vespasian and niece of Domitian. They had at least two sons. Lacking a surviving heir of his own, Domitian designated these boys as intended successors, renaming them Vespasian and Domitian and placing them under the tuition of the rhetorician Quintilian. In 95 Clemens shared the ordinary consulship with Domitian himself, then the highest regular magistracy of the Roman state and a public sign of imperial favor toward this branch of the dynasty.

That favor ended suddenly. Suetonius records that Domitian killed Clemens on a very slight suspicion, describing him as a man of most contemptible inactivity, and that the execution came almost before the consulship was over. Cassius Dio states that Clemens was condemned for atheism, a charge also used against others who had drifted into Jewish customs, and that his wife Domitilla was banished to the island of Pandateria. In Roman usage atheism commonly meant refusal of the traditional cults; Jewish ways might mean Judaism, Judaizing practice, or, as many later Christian and modern writers have argued, Christianity, which Roman observers often classed among Jewish sects. The sources do not settle whether the charge was religiously sincere, a political pretext, or both.

Christian authors of later generations associated the Flavian household with the new faith. Eusebius of Caesarea reports that a Flavia Domitilla, called a niece of the consul Flavius Clemens, was exiled to the island of Pontia as a Christian in Domitian’s last years. Whether that Domitilla is identical with Clemens’s wife or a separate kinswoman remains a standing scholarly problem, as does the question whether Clemens himself was a Christian, a sympathizer, a Judaizer, or merely the victim of a charge framed in religious language. Later tradition sometimes identified the consul with Pope Clement I, the late first-century bishop of Rome associated with the First Epistle of Clement; that identification is not accepted by most modern historians, who treat the consular aristocrat and the Roman church leader as distinct persons. The catacomb of Domitilla on the Via Ardeatina is linked archaeologically and epigraphically with the Flavian family and with early Christian burial, but it does not by itself prove Clemens’s personal conversion or martyrdom.

Domitian was assassinated in 96. The two boys once named as heirs disappear from the record. Domitilla became a figure of Christian memory, and Clemens himself has occasionally been listed among early Roman martyrs in later hagiographic writing, though he has no securely attested independent feast in the principal liturgical calendars. The episode matters for the history of the Flavian dynasty, for Domitian’s final year, and for the difficult question of when and how Christianity first reached the Roman senatorial elite.
