[Easter.] This hymn, in the American Episcopal Hymnal 1892, No. 119, is a mosaic made up of fragments of Easter hymns, pieced together without any regard to the continuity of the originals. It is principally from Dr. Neale's “The foe behind," &c, p. 1148, ii.; from his translation of "En dies est dominica," p. 330, ii.; and Mrs. Charles's version of "Aurora lucis," p. 94, i. [Voice of Christian Life in Song, &c, 1858. p. 100 : "The morning kindles all the sky.") This cento is repeated in several American collections. [Rev. James Mearns, M.A.]
