As this was the most ancient species of measure employed in Roman poetry, as it was universally used before the melody of Greek verse was poured on the Roman ear, and as, from ancient practice, the same strain continued to be repeated till the age of Ennius, by whom the heroic measure was introduced, it would not be suitable to omit some notice of its origin and structure in an account of Roman literature and poetry. Several writers have supposed that the Saturnian measure was borrowed by the Romans from the Greeks(142), having been used by Euripides, and particularly by Archilochus; but others have believed that it was an invention of the ancient Italians(143). It was first employed in the Carmen Saliare, songs of triumph, supplications to the gods, or monumental inscriptions, and was afterwards, as we have seen, adopted in the works of Livius Andronicus and Nævius. In consequence of the fragments which remain of the Saturnian verses being so short and corrupted, it is extremely difficult to fix their regular measure, or reduce them to one standard of versification. Herman seems to consider a Saturnian line as having regularly consisted of two iambuses, an amphibrachys, and three trochaës— ˘ _ | ˘ _ | ˘ _ ˘ | _ ˘ | _ ˘ | _ ˘ A dactyl, however, was occasionally admitted into the place of the first or second trochaë, and a spondee was not unfrequently introduced indiscriminately. It also appears that a Saturnian line was sometimes divided into two—the first line consisting of the two iambuses and amphibrachys, and the second of the trochaës, whence the Saturnian verse has been sometimes called iambic, and at others trochaic. The Hexameter verse, which had been invented by the Greeks, was first introduced into Latium, or at least, was first employed in a work of any extent, by ENNIUS, —— “Qui primus amœno Detulit ex Helicone perenni fronde coronam, Per gentes Italas hominum quæ clara clueret.”
