Gwinear was a saint of the early Celtic period, one of only two early Cornish saints whose biographies survived the Reformation. It was written about 1300 by a priest named Anselm and has sometimes been printed among St Anselm's works (Doble (1960) includes a translation of a large part of the text in which the saint's name is given as Guigner; Doble suggests that the Breton form indicates a connection with Brittany where the saint is also venerated).
Born in Ireland, he was converted to Christianity by St Patrick and after spending time in Brittany went with 7 (or 777) companions to Cornwall, where he was martyred by King Teudar[1][2][3]
