Persian monk and martyr. He was tortured and put to death at Caesarea; his relics were translated to Rome in 640. His cult may have come to England through Theodore of Canterbury. His Life was rewritten by Bede shortly before his death: it is probable that his feast was celebrated at Wearmouth and Jarrow. Feast: 22 January.
