Calliopius

Calliopius is known chiefly as a correspondent of the sophist Libanius of Antioch, who addressed several letters to him in the mid-to-late fourth century AD. The name was borne by more than one man in Libanius's circle (an imperial secretary and assessor, and a teacher/grammarian among them), so the individual behind these particular letters is not securely distinguished; he was most plausibly a member of the educated Greek-speaking provincial milieu around Antioch with whom Libanius maintained the literary friendship and patronage networks typical of his correspondence. Apart from his appearance in this correspondence he is otherwise little attested, and no specific dates, offices, or biographical events can be asserted with confidence.
