Gaius Iulius Erucius Clarus Vibianus
Vibianus came from an Italian family or from one of the Western provinces. He was the son of Gaius Erucius Clarus, consul in 170 AD . He came from the powerful equestrian family of the Erucia and his grandfather Sextus Erucius Clarus was consul in 146 AD and before that City Prefect of Rome. His great-grandfather, who was suffect consul in 117 AD, was the brother (possibly half brother) of Gaius Septicius Clarus. In 193 AD, Vibianus, together with Quintus Pompeius Sosius Falco, was made ordinary consul under the reign of Commodus. Vibianus survived the purges of Septimus Severus that claimed the lives of fellow consuls Q. Pompeius Sosius Falco  and Marcus Silius Messala.
