Which playwright is credited with writing Latin comedies derived from Greek originals known as fabulae palliatae?

The playwright credited with writing Latin comedies derived from Greek originals, known as fabulae palliatae, is Titus Maccius Plautus. Plautus was instrumental in introducing Greek comedic elements to Roman theater and is renowned for his clever use of language, humor, and engaging characterizations. His works often adapted Greek plays and transformed them into witty Latin comedies that resonated with Roman audiences. This genre allowed for a unique blend of cultural expressions, where he maintained the essence of the Greek originals while infusing them with Roman sensibilities.

Gnaeus Naevius, while also an important early Roman playwright, is known more for his historical and epic poetry rather than primarily for adaptations of Greek comedies. Quintus Ennius is considered the father of Roman poetry and is famous for his epic work "Annales," but he did not focus primarily on the comedic genre. Livius Andronicus is more recognized for his tragic works and the translation of Greek plays into Latin rather than the writing of comedies. Hence, Plautus is the key figure associated with fabulae palliatae, making his contribution significant in the context of Latin literature and theater.
