Translated text by J.M. Neale.
John Mason Neale (24 January 1818 – 6 August 1866) was an Anglican priest, scholar and hymn-writer. He was strongly high church in his sympathies, and had to endure a good deal of opposition, including a fourteen years' inhibition by his bishop.
Neale translated the Eastern liturgies into English, and wrote a mystical and devotional commentary on the Psalms.
However, he is best known as a hymn writer and, especially, translator, having enriched English hymnody with many ancient and mediaeval hymns translated from Latin and Greek.
More than anyone else, he made English-speaking congregations aware of the centuries-old tradition of Latin, Greek, Russian, and Syrian hymns. The 1875 edition of the Hymns Ancient and Moderncontains 58 of his translated hymns; The English Hymnal (1906) contains 63 of his translated hymns and six original hymns by Neale.
