Behold the sun that seemed but now. G. Wither. [Afternoon.] First printed in his Hallelujah, or Britain's Second Remembrancer, Lond., 1641, where it is No. 14 of his first part "Hymns Occasional." It is headed "At Sunsetting," and prefaced by the following note, “The singing or meditating to such purposes as are intimated in this Hymn, when we see the sun declining may perhaps expel unprofitable musings, and arm against the terrors of approaching darkness."
It is in 3 stanzas of 8 lines, and its use is by no means equal to its merits. It was included in Farr's reprint of the Hallelujah, 1857; and thence, passing through Lord Selborne's Book of Praise, 1862, was given in Thring's Collection, No. 20, with two slight alterations, Thring reading stanza i., lines 4, "The" for "This"; and in stanza ii., lines 5, "our" for "those." It is also in the Westminster Abbey Hymn Book , 1883. [William T. Brooke]
