Tyfrydog

Tyfrydog (sometimes given as Tyvrydog)[1] was a Christian from north-west Wales in the fifth or sixth century, who was later venerated as a saint.

A nearby standing stone is said to be the remains of a man who he punished for stealing a bible from the church.

[1][2] His father is recorded as being Arwystli Glof ab Seithenyn, active in the middle of the sixth century.

Both he and his father are said to have been part of the Christian community on Bardsey Island, at the tip of the Llŷn Peninsula in north-west Wales.

[8] He is venerated as a saint, although he was never canonized by a pope: as the historian Jane Cartwright notes, "In Wales sanctity was locally conferred and none of the medieval Welsh saints appears to have been canonized by the Roman Catholic Church".
