Grand as the hymn is, it did not come to its full grandeur of sentiment and sound in song-worship till the remarkable music of Dr. John B. Dykes was joined to it. None was ever written that in performance illustrates more admirably the solemn beauty of congregational praise. The name "Nicaea" attached to the tune means nothing to the popular ear and mind, and it is known everywhere by the initial words of the first line. Rev. John Bacchus Dykes, Doctor of Music, was born at Kingston-upon-Hull, in 1823; and graduated at Cambridge, in 1847. He became a master of tone and choral harmony, and did much to reform and elevate congregational psalmody in England. He was perhaps the first to demonstrate that hymn-tune making can be reduced to a science without impairing its spiritual purpose. Died Jan. 22, 1876. "LORD OF ALL BEING, THRONED AFAR." This noble hymn was composed by Dr. Oliver Wendell Holmes, born in Cambridge, Mass., 1809, and graduated at Harvard University. A physician by profession, he was known as a practitioner chiefly in literature, being a brilliant writer and long the leading poetical wit of America. He was, however, a man of deep religious feeling, and a devout attendant at King's Chapel, Unitarian, in Boston where he spent his life. He held the Harvard Professorship of Anatomy and Physiology more than fifty years, but his enduring work is in his poems, and his charming volume, _The Autocrat of the Breakfast Table_. Died Jan. 22, 1896. _THE TUNE._ Holmes' hymn is sung in some churches to "Louvan," V.C. Taylor's admirable praise tune. Other hymnals prefer with it the music of "Keble," one of Dr. Dykes' appropriate and finished melodies. Virgil Corydon Taylor, an American vocal composer, was born in Barkhamstead, Conn., April 2, 1817, died 1891. CHAPTER II. SOME HYMNS OF GREAT WITNESSES. JOHN OF DAMASCUS. [Greek: Erchesthe, o pistoi, Anastaseos Hemera.] John of Damascus, called also St. John of Jerusalem, a theologian and poet, was the last but one of the Christian Fathers of the Greek Church. This eminent man was named by the Arabs "Ibn Mansur," Son (Servant?) of a Conqueror, either in honor of his father Sergius or because it was a Semitic translation of his family title. He was born in Damascus early in the 8th century, and seems to have been in favor with the Caliph, and served under him many years in some important civil capacity, until, retiring to Palestine, he entered the monastic order, and late in life was ordained a priest of the Jerusalem Church. He died in the Convent of St. Sabas near that city about A.D. 780.
