Sweet day, so cool, so calm, so bright. G. Herbert. [Virtue. Spring.] Appeared in his posthumous work, The Temple, 1633, in 4 stanzas of 4 lines, as a poem on "Virtue." (The Chandos Classics, ed. 1887, p. 140.) It is a beautiful poem, but is unsuited as a hymn for congregational use, although found in a few collections for that purpose. I. Walton's reference to it in his Compleat Angler, 1653, is very tender and just: — "'PISCATOR.—And now, scholar! my direction for thy fishing is ended with this shower, for it has done raining. And now look about you, and see how pleasantly that meadow looks; nay, and the earth smells as sweetly too. Come, let me tell you what holy Herbert says of such days and showers as these; and then we will thank God that we enjoy them. "Sweet day, so cool’", &c.
