Nearly all of our modern free verse poets are admittedly indebted to Whitman; Louis Untermeyer names Whitman as the leading influence on modern American poetry. Let us also be thankful that Whitman did not write about the "technique of free verse," about "cadence," "strophe" and "return."
Whitman is without a doubt the father of free verse in America and England to-day. He did not claim to have originated it, since he found a form of it in the prose poetry of the Bible and Ossian. It was also used by Milton and Blake and in German by Goethe and Heine. As Bliss Perry also shows, _The Lily and the Bee_ by Warren, the author of _Ten Thousand a Year_, was written in free verse, before Whitman. Tupper also used it. Free verse was adopted in France and Belgium as a result of Whitman's influence. America owes nothing to French free verse which was usually rhymed and corresponds to the Pindaric Ode founded by Cowley in the middle of the seventeenth century.[119:A]
Dionysius of Halicarnassus was one of the few ancient critics who brought the boundaries of prose and poetry close. His work _On Literary Composition_ contains two chapters on the importance of rhythm, which he considers an important element in prose as well as in verse, and he is especially impressed by the rhythms of Thucydides, Plato and Demosthenes. At the conclusion of this work, which has been translated by W. Rhys Roberts, are two chapters entitled "How Prose Can Resemble Verse," and "How Verse Can Resemble Prose." He wants prose not to be cast in metre or rhythm but simply to appear rhythmical and metrical; the metres and rhythms must be unobstrusively introduced. In this he follows Aristotle's _Rhetoric_ which says prose should have rhythm but of not too marked a character. Dionysius especially shows Demosthenes's great care in the matter of rhythm, and instances as examples of artistic finish among the Greeks the fact that Isocrates worked ten years on his _Panegyrics_. After having shown how prose may resemble verse he points out how verse resembles prose. When the clauses and sense do not coincide with the metrical line but are carried over for completion in another line, the result is prosaic. That is what makes our English blank verse so much like prose.
