Pomponius Mamilianus was a Roman senator who held several offices in the service of the emperor. He was appointed suffect consul in the nundinium of May to June 100 as the colleague of Lucius Herennius Saturninus. He is known through surviving inscriptions,[1] and was a correspondent of Pliny the Younger.
His full name is Pomponius T.f. Gal. Mamilianus Rufus Antistianus Funisulanus Vettonianus, as attested in an inscription recovered at Deva.[2] The sources conflict over his praenomen, however. The Fasti Ostienses show it to be "Lucius"; a military diploma shows it to be "Titus";[3] and the British inscription mentioned above is damaged at that point, and cannot be used to resolve the matter. As for the final element in his name, "Funisulanus Vettonianus", authorities agree it indicates some connection to the general and suffect consul of 78 Lucius Funisulanus Vettonianus, but disagree what connection he has. Some have argued that this is evidence of a Pomponius being adopted by testament by the older Funisulanus Vettonianus, while others have argued he is a son or nephew of the older Vettonianus being adopted by a Pomponius. Olli Salomies concurs with Ronald Syme, and interprets this name as evidence Mamilianus' father or grandfather married a Funisulana, that is a female relative of the older Funisulanus Vettonianus.[4]
