St. Dunstan was an English priest and abbot of Glastonbury Abbey, Bishop of Worcester (and London), and finally from 960 until his death in 988 Archbishop of Canterbury. He played an important role in English politics, and lived in exile in Flanders (955-957). In 973 he officiated at the coronation of King Edgar (the Peaceful), at Bath. The service, devised by Dunstan, still forms the basis of British coronation rituals.
