Behold! how glorious is yon sky. [Eternal Life.] This hymn, in 2 stanzas, is No. 749 in the New Congregational Hymn Book, 1859, and No. 611 in Dr. Alton's Congregational Psalmist Hymnal, 1886. It has evidently been written for or adapted to the fine German chorale, "Wie schon leuchtet der Morgenstern". But not one single line can be said to be translated either from the hymn of Nicolai, or from the recast of Nicolai’s hymn made by J. A. Schlegel (q.v.); and it must rank as an anonymous English hymn.
