Geminus

Geminus is a correspondent addressed in six of Pliny the Younger's letters; he is most commonly identified with Rosianus Geminus, a younger senator whom Pliny took under his patronage. Geminus served as Pliny's quaestor during Pliny's consulship in AD 100, and Pliny afterward promoted his career and commended him to the emperor Trajan, presenting their bond as a model of senatorial friendship and mentorship. He is known almost entirely through this correspondence (and a possible epigraphic trace), and the letters to him are characteristic of Pliny's published collection: polished essays on duty, friendship, grief, and the cultivation of a public reputation in the early second-century AD Roman elite. Beyond his ties to Pliny, little independent detail about his life survives.
