Ancient Sumerian epic poems did not use any kind of poetic meter and lines did not have consistent lengths;instead, Sumerian poems derived their rhythm solely through constant repetition and parallelism, with subtle variations between lines.Indo-European epic poetry, by contrast, usually places strong emphasis on the importance of line consistency and poetic meter. Ancient Greek epics were composed in dactylic hexameter.Very early Latin epicists, such Livius Andronicus and Gnaeus Naevius, used Saturnian meter. By the time of Ennius, however, Latin poets had adopted dactylic hexameter.
