What is "vibius"

Vibius is a Latin praenomen, or personal name, which was occasionally used throughout the period of the Roman Republic and perhaps into imperial times. It gave rise to the patronymic gens Vibia. The feminine form is Vibia. As a praenomen, it was usually abbreviated V.

Although never especially common, the praenomen Vibius appears in a number of Roman families, including the gentes Anicia, Curia, Octavia, Oppia, Sestia, Sextia, and Vedia. The Sestii are the only patrician family known to have used the name, which, like many other praenomina, appears to have been more common in the countryside than at Rome.
