Saint Polybius was a disciple of Saint Epiphanius of Cyprus. He accompanied him on all his journeys and he wrote about the life and miracles of his teacher.
Saint Polybius accompanied Saint Epiphanius when he was returning from Constantinople, unwilling to take part in the council condemning Saint John Chrysostom. As he was dying, Saint Epiphanius told Saint Polybius, “Go to Egypt, and after my death I shall concern myself about you.” Saint Polybius obeyed his teacher’s order with humility and, not waiting for the burial of the body, he went to Egypt, where he was made bishop of the city of Rinocyria.
For his virtuous ascetic life, Saint Polybius was granted the gift of wonderworking. Once, through his prayer, the Lord sent rain during a drought and provided an abundant harvest in the fields. Saint Polybius reposed in the fifth century at an advanced age.
