Dunstan

Dunstan (c. 909 – 19 May 988) was an English bishop and Benedictine monk. He was successively Abbot of Glastonbury Abbey, Bishop of Worcester, Bishop of London and Archbishop of Canterbury, later canonised. His work restored monastic life in England and reformed the English Church. His 11th-century biographer Osbern, himself an artist and scribe, states that Dunstan was skilled in "making a picture and forming letters", as were other clergy of his age who reached senior rank.

Dunstan served as an important minister of state to several English kings. He was the most popular saint in England for nearly two centuries, having gained fame for the many stories of his greatness, not least among which were those concerning his famed cunning in defeating the Devil.
