abbot. He was born at Celles, near Amiens; when a young man and still a pagan, he protected some Irish missionaries who were in danger from the local population. They then instructed him in the Christian faith; he became a priest and went to England for several years. On his return to France he founded a monastery at Celles, became famous as a preacher, and admonished King Dagobert and other magnates. Eventually he resigned his abbacy and became a hermit at Forest-Moutier. There he died on 26 April.
This day is his usual feast, but there is also a translation feast on 9 October, when his relics were moved to the town now called Saint-Riquier (Somme), where a monastery was founded later. Riquier appears frequently in ancient calendars and litanies. One English church was dedicated to him at Aberford (W. Yorks.).
