A third-century bishop of Ostia, the ancient port city of Rome, who governed his see for several years until his death around 235.

Saint Ciriaco di Ostia served as bishop of Ostia, the port city of ancient Rome situated at the mouth of the Tiber, governing his see from around 229 until his death in 235. Ostia’s bishopric held particular ecclesiastical significance in Rome’s ecclesiastical geography, and Ciriaco led his community through the middle years of the third century, a period that preceded the more severe empire-wide persecutions that would follow later in the century.
