Botwulf of Thorney was a 7th-century Benedictine abbot from England. Born to noble Saxon parents, he studied under Saint Fursey before traveling to the Continent to join a Benedictine order. Upon returning to England, he established a monastery at Icanho, a site that was once a tidal island. Through his leadership, he and his fellow monks transformed marshy, desolate lands into productive agricultural areas. He also served as a missionary throughout East Anglia, Kent, and Sussex, earning a reputation for his spiritual grace and learning.
