Very little is known about Brioc's early life, as his 9th century is not altogether reliable. It states that he came from Ceredigion where, indeed, he has a church at Llandyfriog. He received his education in Ireland and then studied under Germanus of Auxerre. He is believed to have spent time at Rothesay on the Isle of Bute in Scotland, where a church was dedicated to him and his name was commemorated in the annual St. Bruix Fair. He most likely returned to France early in 431, accompanied by Saint Illtud. In 480, he settled in Armorica, and founded a monastery at Landebaeron. He then traveled to Upper Brittany where he established an oratory at St Brieuc-des-Vaux, between St. Malo and Land Triguier, where he eventually became the abbot of a monastery. Authorities differ as to date of Saint Brioc'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 Saint Stephen. Rothesay, Bute
Veneration
His Acta cites numerous miracles, especially his cure of Count Riguel, who gave the saint his own Palace of Champ-du-Rouvre as also the whole manorial estates. He is represented as treading on a dragon or presented with a column of fire as seen at his ordination. Saint Brioc's relics were moved to the Church of Saints 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. In honour of Saint Brioc's link between Ceredigion and Brittany, the town of St Brieuc has been twinned with Aberystwyth since 1974 and a road, Boulevard St Brieuc, is located in the town. His feast day is 1 May. The festival of Saint Brioc was celebrated on 1 May, but in 1804, the festival has been held on the second Sunday after Easter. Churches in England, Ireland, and Scotland are dedicated to this early Celtic saint, including the parish church of St Breock in Cornwall. He is considered the patron saint of pursemakers.
