Praetexta

A Praetexta or Praetexta Fabula was a new genre of Roman tragedy innovated by Gnaeus Naevius, which dealt with the themes of historical Roman figures, instead of the conventional Greek myths. Subsequent writers of praetextae included Ennius, Pacuvius and Lucius Accius. The name refers to the toga praetexta, the official dress of Roman magistrates.
