S. Callistus I papa, Epistolae

Pope Callistus I (d. 222), ascribed: the two Pseudo-Isidorian letters, the first to Bishop Benedict, on the ember fasts, accusations against teachers and church discipline, in Latin, with the editors' notes (Migne, PG 10). The text was first read by Gemini (a machine reader), and the Reading Room checked a sample of its columns against the page.
