Decadence and spectacle dominated the theater of ancient Rome. Fewer plays were being written, and most of those seemed to be a knock-off of old Greek Myths (transplanted with the very similar Roman Gods). Perhaps the noted exception to this rule would be the domestic comedies of Plautus and Terrence. And of course, Seneca - perhaps the best known tragedian. He is a prime example of a playwright who was must have pushed boundaries because one day Emperor Nero ordered Seneca to kill himself. And Seneca obeyed, thus making Nero history's most fearful drama critic.
The Roman Republic and its subsequent empire greatly enjoyed the arts and entertainment. However, of the many playwrights of ancient Rome, only a small percentage of plays have survived the passage of time.
