Other epic poets followed Naevius. Quintus Ennius wrote a historical epic, the "Annals" (soon after 200 BC), describing Roman history from the founding of Rome to his own time. He adopted Greek dactylic hexameter, which became the standard verse form for Roman epics. He also became famous for his tragic dramas. In this field, his most distinguished successors were Marcus Pacuvius and Lucius Accius. These three writers rarely used episodes from Roman history. Instead, they wrote Latin versions of tragic themes that the Greeks had already handled. But even when they copied the Greeks, their translations were not straightforward replicas. Only fragments of their plays have survived.
