Brioch (Brieuc) was a Celtic saint of Brittany, educated in Ireland and then under St Germanus. The Catholic Encyclopedia says much of what is told about his early years must be taken with caution.

He returned to France early in 431 and later settled in Armorica, where he founded a monastery. He then went to Upper Brittany and built an oratory at the place since called St Brieuc-des-Vaux, becoming its first bishop. His Acts (the written account of a martyr's trial and death) tell of many miracles, among them the cure of Count Riguel, who gave him his own palace and estates.

He probably died in 502 or early in the sixth century, in his monastery, and was buried in his cathedral. Churches in England, Ireland and Scotland are dedicated to him.

Germain of Paris, or of some other saint of the same name, is unknown, He preached in Brittany, where his knowledge of the Keltic tongue made him useful as an apostle. At Tr^guier he converted a chief named Conan, who gave him lands at Landebaeron whereon to found a monastery. He afterwards went Eastward, and was well received by the chief Rignal, who lived near the mouth of the river Gonet, and who gave him a site, whereon he built a monastery, called S. Brieuc-des-Vaux, because it is at the junction of several valleys.

A Celtic saint of Brittany who received his education in Ireland and then studied under St. Germanus said to be the famous St. Germanus of Auxerre. Much of what we read concerning his early years must be received with caution; indeed, Ussher asserts that he was of Irish birth, but it is tolerably certain that he returned to France early in 431, bringing with him St Iltud. Even before his ordination to the priesthood, St. Brieuc worked several miracles duly chronicled in his "Acts" (edited by F. Godefrid Herschenn), and after a short period spent with his parents, he entered on his missionary career. In 480, he settled in Armorica [Brittany in north-west France], and founded a monastery at Landebaeron. Thence he proceeded to Upper Brittany where he established an oratory at a place ever since known as St. Brieuc-des-Vaux, between St. Malo and Land Triguier, of which he was named first bishop. Numerous miracles are cited in the "Acts", especially his cure of Count Riguel, who gave the saint his own Palace of Champ-du-Rouvre as also the whole manorial estates. Authorities differ as to date of St. Brieuc's death, but it was probably in 502, or in the early years of the sixth century. He died in his own monastery at St. Brieuc-des-Vaux and was interred in his cathedral church, dedicated to St. Stephen. Baring-Gould says that St. Brieuc is represented as "treading on a dragon", or else "with a column of fire" as seen at his ordination. His relics [the bodily remains of a saint, or objects they used, kept with honor] were translated to the Church of SS. Sergius and Bacchus of Angers in 865, and again, in a more solemn manner, on 31 July, 1166. However, in 1210, a portion of the relics was restored to St. Brieuc Cathedral, where the saint's ring is also preserved. The festival of St. Brieuc is celebrated on 1st May, but, since 1804, the feast is transferred to the second Sunday after Easter. Churches in England, Ireland, and Scotland are dedicated to this early Celtic saint.
