Dyfnog

Saint Dyfnog was a Welsh saint of the seventh century, much venerated in Clwyd.

He was the son of Medrod, son of Caradog Freichfras, and came to that region from the north of Britain. He is said to have come from a wealthy family but chose to become a monk and live simply. He built a small wooden church on the site where the church of Saint Dyfnog at Llanrhaeadr stands today. The sixteenth-⁠century Welsh poet Dafydd ap Llywelyn ap Madog included a tribute to him; it is told that the poet was cured of a pain in his ribs and made a pilgrimage to the saint's well in thanksgiving. An anonymous poem of the seventeenth century says there was an image of him in the church at Llanrhaeadr and describes him as a man who had renounced the world, wore a shirt of coarse horsehair fastened with an iron belt, lived on bread and water and did penance by standing under a stream of cold water.

He is a saint of the undivided Church, commemorated on 13 February (new style).
