Dun´stan, St., an English archbishop and statesman, was born at Glastonbury in 925, died at Canterbury 988. As a youth he was remarkable for his learning and his skill in music, painting, carving, and working in metals. He entered the Benedictine order, became an anchorite at Glastonbury, and in 945 was made abbot by King Edmund. After the death of Edmund, Edred, the next king, made him his Prime Minister and principal director in civil and ecclesiastical affairs. In the reign of Edwy he was banished, but was recalled by Edgar, and made Archbishop of Canterbury. He was again

deprived of power on the accession of Ethelred in 978, and devoted the last years of his life to his diocese and the literary and artistic pursuits of his earlier days. He did much to improve education and to raise the standing and character of the priesthood. The old biographies of him have all a large legendary element.—Cf. W. Stubbs (editor), Memorials of St. Dunstan (Rolls Series, 1874).

After issuing a volume of poems in 1844, he went to Paris and obtained a place in the office of the secretary of the Institute. Some of his songs, such as Song of Bread and Song of the Workers, had a Socialistic ring which proved obnoxious to the Government which came into power in Dec., 1852. He was arrested, imprisoned, and condemned to be banished for seven years; but his release was soon procured. His poems have been collected under the titles Cahiers de Chansons, La Muse Populaire, Chants et Chansons, Poésie et Musique, and Études Littéraires.
