Bain of Thérouanne

Saint Bain of Thérouanne (also called Bainus, Bagne or Bagnus) was a disciple of Saint Wandrille, a monk at Fontenelle in Normandy, then bishop of Thérouanne in north-⁠western France and then abbot of the monastery of Saint-⁠Wandrille. He reposed around 710 or 711. After twelve years as bishop he returned to Fontenelle and became abbot. One source says he also presided over the monastery of Fleury (Saint-⁠Benoît-⁠sur-⁠Loire).

According to Alban Butler he was the fifth bishop of that see (now Saint-⁠Omer), promoted before the middle of the seventh century. Of his episcopate it is remembered that he moved the body of Saint Amatus from Merville to the church that Saint Maurontus had built at Douai. He is the main patron of the city of Calais. He is commemorated on 20 June as a saint of the West before the Great Schism (a saint of the undivided Church), by the New Calendar.
