Dunstan

Dunstan (909 – 19 May 988) was an Abbot of Glastonbury Abbey, a Bishop of Worcester, a Bishop of London, and an Archbishop of Canterbury, later canonised as a saint. 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.
