Saint Gwinear was a Celtic martyr born in Ireland around 350. Originally known by the Irish name Fingar, he became a follower of Saint Patrick. After traveling through Brittany, he arrived in Cornwall with a group of companions. He is notable for being one of the few early Cornish saints whose biography, written by a priest named Anselm in the early 14th century, survived the Reformation.
Life and martyrdom

According to tradition, Gwinear landed at Hayle in Cornwall alongside several followers. There, he was martyred by King Teudar, who reportedly had the group thrown into a pit filled with reptiles. Some accounts suggest this execution occurred in Brittany under Prince Tewdwr instead. A Victorian scholar proposed that the legend might actually reflect historical Irish invasions of the Penwith region during the fifth century.
Veneration
The saint is commemorated on March 23. His legacy is preserved through the surviving medieval biography, which has occasionally been associated with the works of Anselm of Canterbury. He is recognized within the Catholic and Orthodox traditions.
