Gaius Julius Silanus was a Roman senator and general who held a series of offices in the emperor's service. He was suffect consul for the nundinium of January to April 92 as the colleague of Quintus Junius Arulenus Rusticus.[1] Silanus is known solely through inscriptions.
Ronald Syme speculates Silanus came from Tres Galliae, and adds that "the cognomen need have nothing to do with the aristocratic Junii Silani."[2] He was co-opted into the Arval Brethren on 22 January 86 to replace the recently deceased Gaius Vipstanus Apronianus.[3] While he was appointed magister in the year 87, he was absent from the records of the sodales for the rest of that year, and again from 89 to 91; Syme speculates Silanus was absent due to imperial appointment either to command a legion or to govern one of the eight imperial praetorian provinces.[4]
