It was entirely appropriate that, for his heroic narrative, Ennius borrowed the dactylic hexameter of the Greeks, but it was after all a daring thing to do, since meters seldom transplant with success. However, Naevius’ use of the native Saturnian had demonstrated its inability to carry heroic narrative. Imagine _Paradise Lost_ crammed into the primitive English rhythms of Langland! The dactylic hexameter was in Greek regularly associated with the epic. It had one disadvantage in its requirement of a larger proportion of short syllables than normal Latin writing contained, but that was overcome by simply permitting more spondees than Homeric custom had enjoyed. This resulted in a reduction of tempo which after all suited Roman military movement. There was another difficulty which was more serious. While Greek verse needed to give little attention to word accent, the Latin word accent was jealous of attention. With the relative fixity of the accent, it was impossible to write Latin dactyls based both upon quantity and word-accent. Ennius nevertheless ventured upon an experiment. That he had a very delicate ear for the demands of the Latin language is proved by the careful adjustments in his dramatic senarii, where adjustments were not easy to make. He would not have foisted impossible dactyls upon Rome. The fact that he wrote quantitative dactyls and continued to write them, and that his _Annals_ lived for centuries is proof that he did not overstep the bounds of good taste. The explanation of his success is probably that the word stress in the Latin of his day was so moderate that a conflict with the ictus was not fatal to aesthetic pleasure if only it fell upon long syllables, and also that during the forty years of dramatic performances at Rome, the ears of the audiences had become trained under the influence of music to disregard such conflicts in the many lyric rhythms, including dactyls. By his sensible modification of the Homeric line, Ennius created as great a resource for Latin poetry as Chaucer did for English poetry, and shaped for Vergil’s use “the stateliest measure ever moulded by the lips of man.”
