Titus Prifernius Paetus Rosianus Geminus was a Roman senator of the second century who held a series of posts in the emperor's service.
His family was prestigious not only on the wider level but also on the local; Paetus is recorded holding all of the municipal posts of his home city.
Upon returning to Rome, he held the traditional Roman magistracies -- quaestor, plebeian tribune and praetor—all with the recommendation of the emperor Hadrian.
Edward Dabrowa attributes this favor to the intercession of either his father or the well-known lawyer and friend of the Emperor, his brother-in-law Publius Pactumeius Clemens.
He also held a series of consular offices: curator alvei Tiberis et cloacarum Urbis, praefectus alimentorum;[6] then two governorships, that of Dalmatia from 153 to 156,[7] and the pinnacle of senatorial success, proconsular governor of Africa in 160/161.
