Gaius Vibius Rufus

Gaius Vibius Rufus was a Roman senator and orator, who flourished during the Principate. He was suffect consul in the second half of AD 16 with Gaius Pomponius Graecinus as his colleague. The first of his family to achieve consular rank, Rufus was a homo novus, one of ten in the first five years of the reign of Tiberius.

Ronald Syme notes both inscriptions which attest to his consulate misrepresent his name. In the Fasti Antiates Minores, his name appears as "C. Vibius Libo". Syme explains the person who carved this inscription accidentally repeated "Libo" from the name on the line above: L. Scribonius Libo. The second is in the Fasti Ostienses, where he is presented as "[C. Vibius] Rufinus"; in this case, the engraver was distracted by the name on the next line, "C. Pomponius Graecinus."
