Saint Polybius Bishop in Cyprus

Saint Polybius was a fifth-century disciple and companion of Saint Epiphanius of Salamis, the renowned bishop of Cyprus and defender of the apostolic faith. According to the synaxarion he accompanied Epiphanius on all his journeys and later himself served as a bishop, reposing among the saints commemorated on May 12, the feast he shares with his teacher.

Polybius is remembered above all as a recorder of Epiphanius's life: tradition credits him with writing about the life and the miracles of his teacher, so that his witness preserves much of what is known of the great Cypriot hierarch. The in-repo record describes him simply as a bishop in Cyprus; the wider hagiographical tradition associates his see with Rhinocorura (Rhinocyra) in Egypt.

The sources for Polybius are brief, and little is related of his own episcopate apart from his closeness to Epiphanius and his role as the chronicler of his teacher's deeds. He belongs to the circle of saints around Epiphanius commemorated in Cyprus, which also includes Saint Sabinus, who succeeded to the hierarchy on the island, and Saint Philo of Karpasia, whom Epiphanius ordained.
