How did Ennius adapt Greek hexameter for his epic Annales?

In his epic Annales, Quintus Ennius adapted the Greek dactylic hexameter—the traditional metre of Homer—to the Latin language.12

While earlier Roman poets, such as Livius Andronicus and Gnaeus Naevius, had relied on traditional Italian measures for their epic works, Ennius broke with this practice by adopting the Greek framework. By "Latinizing" this metre, he successfully integrated a sophisticated Hellenistic poetic structure into the Roman literary tradition. This innovation allowed him to elevate the style and diction of Roman epic poetry, creating a model of expression that would later reach its peak in the works of Virgil.21
