Where unless we pronounce the Particle A with a strong Accent upon it, and make it sound like the Vowel a in the last Syllable but one of Ecclesiastick, the Verse will lose all its Beauty and Rhyme. But this is allowable in Burlesque Poetry only.
Observe that these double Rhymes may be compos'd of two several Words; provided the Accent be on the last Syllable of the first of them; as in these Verses of Cowley, speaking of Gold;
A Curse on him who did refine it,
A Curse on him who first did coin it.
Or some of the Verses may end in an entire word, and the Rhyme to it be compos'd of several; as,
Tho' stor'd with Deletery Med'cines,
Which whosoever took is dead since.Hud.
The Treble Rhyme is, when in words accented on the last save two we begin the Rhyme at the Vowel of that Syllable, and continue it to the end of the word: Thus Charity and Parity, Tenderness and Slenderness, &c., are treble Rhymes. And these too, as well as the double, may be compos'd of several words; as,
There was an ancient sage Philosopher,
That had read Alexander Ross over.Hud.
The Treble Rhyme is very seldom us'd, and ought wholly to be excluded from serious Subjects; for it has a certain flatness, unworthy the Gravity requir'd in Heroick Verse. In which Dryden was of Opinion that even the double Rhymes ought very cautiously to find place; and in all his Translation of Virgil, he has made use of none except only in such words as admit of a Contraction, and therefore cannot properly be said to be double Rhymes; as Giv'n, Driv'n, Tow'r, Pow'r, and the like. And indeed, considering their Measure is different from that of an Heroick Verse, which consists but of 10 Syllables, they ought not to be too frequently us'd in Heroick Poems; but they are very graceful in the Lyrick, to which, as well as to the Burlesque, those Rhymes more properly belong.
