Such, therefore, were the conditions and fortunate coincidences which produced the finest heroic poetry. You had the popular hero--the noble warrior who knew his business; and you had also the poet or story-teller who knew his art, could give you a dramatic picture founded upon fact, and could always keep close to reality, without crowding his canvas with unnecessary particulars; he gave you the ruling motives, actions, and feelings of the age. The excellence of the work lay in simplicity and directness of treatment, in a sureness of line drawing, in a power of striking the right note, whether of praise or sorrow, of glory or grief. There is no staginess or far-fetched emotion, or artificial scene-painting: the style strikes the right chords of passion or pity, and stamps upon the mind a vivid impression of situation and character. Moreover, the heroic poet, as a composer, had this advantage in early days, that continual recital before an appreciative public must have had the effect of polishing up his best verses, and polishing off his bad ones. As the theme was always some well-known story or personage, it was possible to omit details and explanations, and to go straight to the points that repetition had proved to be the most effective, so that the criterion of excellence must have been immediate popularity with the audience as in a play. It may be conjectured also that the metre, in length of line and cadence, formed itself to a great degree on the natural conditions of oral delivery and listening. For all poetry, I think, makes its primary appeal to the ear; and the modern habit of reading it seems to me to have thrown this essential test of quality somewhat into the background. The arrangement of metre and rhyme may have been gradually invented to correspond with and satisfy that natural expectation of the recurrence of certain tones and measures which always delights primitive men, and of which one may possibly trace some symptoms even in animals, as when the snake sways slowly to the simple sounds of a snake-charmer's pipe. The order of all modern versification (except in blank verse, which is never popular) depends on the echoing rhyme, which marks time like the stroke of a bell, and is waited for with keen anticipation by the sensitive listener. It is strange, to my mind, that such a beautiful creation as the beat of tonic sounds at a line's terminal should have been comparatively so recent a discovery in European poetry.
