(a) From The Preface to Theatrum Poetarum, or a Compleat Collection of the Poets (1675), sigs. ★★3v−★★4; repr. J.E. Spingarn, Critical Essays of the Seventeenth Century (Oxford, 1908-9) II. 265:
There is certainly a decency in one sort of Verse more than another which custom cannot really alter, only by familiarity make it seem better; how much more stately and Majestic in Epic Poems, especially of Heroic Argument, Spencer's Stanza (which I take to be but an Improvement upon Tasso's Ottava Rima, or the Ottava Rima it self, used by many of our once esteemed Poets) is above the way either of Couplet or Alternation of four Verses only, I am persuaded, were it revived, would soon be acknowledg'd.
(b) Ibid., sigs. ★★9−★★9v; repr. Spingarn, II. 271:
Nay, though all the Laws of Heroic Poem, all the Laws of Tragedy were exactly observed, yet still this tour entrejeant, this Poetic Energie, if I may so call it, would be required to give life to all the rest, which shines through the roughest most unpolish't and antiquated Language, and may happly be wanting, in the most polite and reformed: let us observe Spencer, with all his Rustie, obsolete words, with all his roughhewn clowterly Verses; yet take him throughout, and we shall find in him a graceful and Poetic Majesty.
