Career
He was appointed consul with Quintus Pompeius Sosius Falco in AD 193 under the reign of Commodus. Vibianus came from an Italian family or from one of the Western provinces. He was the son of Gaius Erucius Clarus, consul in AD 170.
His great-grandfather, who was suffect consul in AD 117, was the brother (possibly half brother) of Gaius Septicius Clarus.
Vibianus survived the purges of Septimus Severus that claimed the lives of fellow consuls Q. Pompeius Sosius Falco and Marcus Silius Messala. As a follower of the usurper and Governor of Britain Clodius Albinus, after the defeat and death of Albinus against Septimius Severus in 197, Vibianus was executed.
