English: Stained glass window. Bishop and confessor, one of the greatest of Welsh saints and so is in the top row of the stained glass windows. He is usually represented holding two crosiers, which signify his jurisdiction over the Sees of Caerleon and Llandaff.According to this account he was the son (by an unnamed father) of Eurddil, a daughter of Pebia Claforwg, prince of the region of Ergyng (Erchenfield in Herefordshire), and was born at Madley on the River Wye. As a child he was noted for his precocious intellect, and by the time he attained manhood was already known as a scholar throughout Britain. He founded a college at Henllan (Hentland in Herefordshire), where he maintained two thousand clerks for seven years. Thence he moved to Mochros (perhaps Moccas), on an island farther up the Wye, where he founded an abbey. Later on he became Bishop of Llandaff, but resigned his see and retired to the Isle of Bardsey, off the coast of Carnarvonshire. Here with his disciples he lived as a hermit for many years, and here he was buried. His body was translated by Urban, Bishop of Llandaff, to a tomb before the Lady-altar in "the old monastery" of the cathedral city, which afterwards became the cathedral church of St. Peter.
