up far more elaborately organised rhythmical structures than we are accustomed to, with our simpler lyrical forms. Structure, with us, is generally delineated and emphasised by[Pg 44] rime, rather than by internal variations and contrasts of rhythm. Even in the unrimed choruses of Samson Agonistes the rhythm is far more uniform than in the simplest Greek lyrical poems. I do not suggest that it would be possible or desirable artificially to change the nature of English poetical rhythm from an accentual to a quantitative basis, as Ennius did with Latin prosody. But although no doubt purely quantitative English verse will always remain somewhat of an exotic curiosity, I feel sure that if more conscious attention were paid to the quantity of English syllables, not only would our normal verse-forms, such as blank verse, gain in subtlety and expressive force, but all sorts of new possibilities of lyrical structure could be discovered and explored. Rime need not necessarily be dispensed with; but it would no longer be the only effective instrument for binding together a complicated lyrical stanza. Stress[Pg 45] would still indicate and govern internal rhythm; but careful attention to the length and shortness of syllables would make it possible to build up far more elaborate and varied metrical structures than have hitherto been attempted. The result might be a verse that was genuinely free, yet did not degenerate into prose, based upon irregular but easily comprehensible metrical patterns, that could mould and dominate language as effectively as the older, more rigid verse-forms. [Pg 44] [Pg 45] [Pg 47] [Pg 47] CHAPTER IV Poetic Material Poetic Material Difficult as it must be to foresee the evolution of technical methods, it would be still more hazardous to attempt any prediction as to the new subject-matter which poets will have to discover, if their art is to continue as a living growth. The mind of even the most detached artist is a part of the world into which he was born, and his matter must to a large extent be a reflection of his environment. But the material and spiritual world changes far more swiftly than the language and the rhythmical artifices which constitute the poetic medium. And so,
