# Vibia gens

The gens Vibia was a plebeian family at ancient Rome. Although individuals named Vibius appear in history during the time of the Second Punic War, no members of this gens are found at Rome until the final century of the Republic. The first of the Vibii to obtain the consulship was Gaius Vibius Pansa in 43 BC, and from then until imperial times the Vibii regularly filled the highest offices of the Roman state. The emperors Trebonianus Gallus and Volusianus each claimed descent from the family.

## Origin

The nomen Vibius is a patronymic surname, derived from the praenomen Vibius. The name is generally regarded as an Oscan praenomen, and it is found extensively in Campania, but it was also used in Latium, and appears at Rome from a very early period, being used by the patrician Sestii, and occasionally by members of several prominent plebeian families. The Vibian gens itself was probably Oscan.

## Praenomina

The main praenomina of the Vibii were Gaius, Lucius, and Quintus. A family of imperial times used the praenomen Titus, while individual examples of Aulus and Sextus are known.

## Branches and cognomina

The cognomina of the Vibii under the Republic were Pansa and Varus, each of which occurs on coins. Both surnames derive from the physical characteristics of the persons to whom they originally applied; Pansa translates as "splay-footed", while Varus is "knock-kneed".

Pansa Caetronianus, consul in 43 BC, led the Roman forces against the supporters of Marcus Antonius at the Battle of Forum Gallorum, where he gained the victory thanks to the assistance of his colleague, Aulus Hirtius.

He was governor of Hispania Ulterior in 23, when he was condemned and exiled to the island of Amorgus in the Cyclades, on a charge of vis publica, riot or revolt, but in reality because he was an enemy of Sejanus. He was recalled the following year, after his own son accused him of plotting against Tiberius, but was subsequently returned to Amorgus.
* Gaius Vibius C. f. Marsus, consul suffectus from the Kalends of July in AD 17, and probably governor of Africa around AD 20. He was later accused of being one of the accomplices of Albucilla, but escaped condemnation by the death of Tiberius in 37. He was governor of Syria in 47.
