Corentin of Quimper was a fifth-century saint and the inaugural bishop of Quimper in Brittany. Born in the region of Cornouaille, he initially lived as a hermit in Plomodiern. He is recognized as one of the seven legendary saints who evangelized the area. According to tradition, he was appointed to his episcopal seat by King Gradlon, who requested that he be consecrated by Martin of Tours. He is celebrated as a patron of seafood and the region of Cornouaille.
Life and legends


As a hermit, Corentin was known for his devotion and humanitarian spirit. Local legends describe a miraculous fish that would appear in a fountain, providing him with a piece of meat that would perpetually regrow. He is also central to the myth of the sunken city of Ys, where he reportedly warned King Gradlon about the sins of the princess Dahut. Following his death in 460, he was interred at the site of the current Quimper Cathedral.
Veneration and legacy

Corentin is honored through the Tro Breiz, a pilgrimage connecting the sites of the seven founding saints of Brittany. His feast day is observed on December 12. In religious art, he is frequently depicted holding a fish or standing near a fountain, representing the miraculous sustenance he received. He remains a significant figure in Breton tradition and is commemorated in both Catholic and Orthodox calendars.
