prince of Glamorgan, hermit. All that is known of him comes from the Book of Llan Dav. According to this late source, he resigned the rule of his people in old age to his son Meurig, and became a hermit at Tintern. In a chance invasion of Saxons he once again placed himself at the head of his people. The invaders were put to flight but Tewdrig was mortally injured by a lance. He died and was buried at Mathern, near Chepstow. This was formerly called Merthyr Tewdrig and the church is still dedicated to him. He is also said to have founded the churches of Bedwas Llandow, and Merthyr Tydfil. Francis Godwin, bishop of Llandaff from 1601 to 1617, discovered in the church at Mathern a stone coffin containing the saint's skeleton, which had a badly fractured skull. Feast: according to William Worcestre and Stanton, 1 April; other late authorities give 3 January.
