4. _The thorough knowledge and sure portrayal of men and women which, belong to his mature work extend through, many various types of character._ It is a commonplace to say that the Prolog to 'The Canterbury Tales' presents in its twenty portraits virtually every contemporary English class except the very lowest, made to live forever in the finest series of character sketches preserved anywhere in literature; and in his other work the same power appears in only less conspicuous degree. 5. _His poetry is also essentially and thoroughly dramatic_, dealing very vividly with life in genuine and varied action. To be sure, Chaucer possesses all the medieval love for logical reasoning, and he takes a keen delight in psychological analysis; but when he introduces these things (except for the tendency to medieval diffuseness) they are true to the situation and really serve to enhance the suspense. There is much interest in the question often raised whether, if he had lived in an age like the Elizabethan, when the drama was the dominant literary form, he too would have been a dramatist. 6. _As a descriptive poet (of things as well as persons) he displays equal skill._ Whatever his scenes or objects, he sees them with perfect clearness and brings them in full life-likeness before the reader's eyes, sometimes even with the minuteness of a nineteenth century novelist. And no one understands more thoroughly the art of conveying the general impression with perfect sureness, with a foreground where a few characteristic details stand out in picturesque and telling clearness. 7. _Chaucer is an unerring master of poetic form._ His stanza combinations reproduce all the well-proportioned grace of his French models, and to the pentameter riming couplet of his later work he gives the perfect ease and metrical variety which match the fluent thought. In all his poetry there is probably not a single faulty line. And yet within a hundred years after his death, such was the irony of circumstances, English pronunciation had so greatly altered that his meter was held to be rude and barbarous, and not until the nineteenth century were its principles again fully understood. His language, we should add, is modern, according to the technical classification, and is really as much like the form of our own day as like that of a century before his time; but it is still only _early_ modern English, and a little definitely directed study is necessary for any present-day reader before its beauty can be adequately recognized.
