Bless'd morning! whose young, dawning rays. I. Watts. [Sunday—Easter.] Appeared in his Hymns, &c, 1707 (1709, Book ii., No. 72), in 5 stanzas of 4 lines, and entitled, "The Lord's Day: or, The Resurrection of Christ." The arrangements of this hymn in common use are:—
(1.) The original. Very limited.
(2.) "Blessed morning” &c, as in Dr. Hatfield's American Church Hymn Book, N. Y., 1872, with the change in stanza i., line 4, of "last abode," to "dark abode."
(3.) "Blest morning," &c. This opening, sometimes followed by two or three slight alterations and the omission of stanza v., is the most popular form of the text both in Great Britain and America.
(4.) "Blest morning," &c, in the Hymnary, 1872, No. 13. This is very considerably altered.
In addition to these, in 1781, this hymn was added with alterations, as "Hymn IV.," to the Scottish Translations & Paraphrases. It opens "Blest morning ! Whose first dawning rays." The author of this recast is unknown.
