This became a very popular textbook, especially in England. The other influential French author was Odo of Cluny, who was probably a mentor of Oda, Archbishop of Canterbury (941–958), a driving force behind the English Benedictine Reform and a proponent of the hermeneutic style. Lapidge suggests that the style in northern France was particularly associated with centres of the Cluniac (Benedictine) reform, and the leading figures in the English reform, Oda, Dunstan, Æthelwold and Oswald, were all practitioners of the hermeneutic style and had strong connections with Continental Benedictine centres.
