Portrait of George Saintsbury George Saintsbury Historical Manual of English Prosody

Being possessed of great literary and even distinctly poetical genius, he makes it a by no means unsuitable vehicle for his tangle of apocalyptic dreams, and no ill one for the occasional passages of a more mundane description which he interlards. But it is deficient in beauty, if not in vigour; it is clearly unsuited for many of the subjects of poetry; and to any one acquainted with metre and rhyme it constantly suggests the question and complaint, "Why are we to be deprived of these already-won beauties and conveniences, and cut off with this rough makeshift?"

In Shakespeare first the whole freedom, as well as nearly the whole order, of English prosody discovers itself. But this freedom is pushed by others to licence, and blank verse becomes practically as ruinous a heap as the rhyme-royal of the fifteenth century, with one form of decasyllabic couplet keeping it company, if not quite in actual cacophony, at any rate in disorderly slackness.

Equivalence means, prosodically, the quality or faculty which fits one combination of syllables for substitution in the place of another to perform the part of foot, as the dactyl and spondee do to each other in the classical hexameter, and as various feet do to the iamb in the Greek iambic trimeter and other metres. It is, with its correlative, Substitution itself, the most important principle in English prosody; it emerges almost at once, and, though at times frowned upon in theory, never loses its hold upon practice.
