Martyr, who is said to have preached the Gospel in Gaul in the third century and to have died at Beauvais. His relics were discovered in the 7th century and were famous for miracles 100 years later. With his two companions he is culted in the Sarum calendar and one English church is dedicated to him. Feast 8 January, the day after that of Lucian of Antioch, with whom he is sometimes confused. Some scholars, such as L. Duchesne, consider the whole story of Lucian as unhistorical.
