Calvisia gens
The gens Calvisia was an ancient Roman family, which first rose to prominence during the final decades of the Republic, and became influential in imperial times. The first of the gens to obtain the consulship was Gaius Calvisius Sabinus in 39 BC. Origin
The nomen Calvisius is probably based on the Latin adjective calvus, meaning "bald". Both Calvus and its diminutive, Calvinus, were common Roman surnames. With respect to their place of origin, Ronald Syme begins a survey of the evidence by stating, "Calvisii might issue from any region of Italy except old Latium." He lists a placename, "villa Calvisia" in Southern Etruria, amongst the properties of a Hadrianic consular; two Calvisii attested in Puteoli, and fifteen named in sources from Transpadane Italy, but concludes "[y]et they lead nowhere"; the evidence is frustratingly inconclusive. However, for one branch of the gens, the Calvisii Rusones, Syme suggests that their origins lay in Gallia Narbonensis. A further clue lies in the surname Sabinus, borne by the only distinct family of the early Calvisii, which may point to a Sabine origin. Praenomina
The main lines of the Calvisii employed the praenomina Gaius and Publius, both of which were amongst the most common of Roman names. Branches and cognomina
Most of the Calvisii appearing in history belong to one of two distinct families, bearing the surnames Sabinus and Ruso. Sabinus, belonging to the earlier of the two, typically indicated Sabine ancestry, although as an adjective it could also suggest that the original bearer resembled a Sabine, either in his appearance or manner. The Calvisii Sabini flourished from the end of the Republic to about the time of the emperor Claudius, when the surname is replaced by that of Ruso. The latter surname might be formed from rus, the country, or russus, ruddy or red-haired; the latter derivation is suggested by the fact that two later Calvisii, whose relationship to the others is unclear, bore the surname Rufus, which generally referred to someone with red hair.
