Cassius Dio (consul 291)
Cassius Dio was either the grandson or great-grandson of his namesake, the historian Cassius Dio, whose family originated in Bithynia. He was appointed consul posterior in AD 291 alongside Gaius Junius Tiberianus at quite a young age. This was followed by a posting as Proconsular governor of Africa from approximately 1 July 294 to 1 July 295. Then on 18 February AD 296, he was appointed Praefectus urbi of Rome, a position he held until AD 297.
