In Dryden's "Essay of Dramatic Poesy" (1668), the discussion takes place between four characters: Crites, Eugenius, Lisideius, and Neander. Each character represents a different critical perspective on drama.
Crites represents the side of the Ancients. He argues in favor of the classical dramatists of ancient Greece and Rome, praising their adherence to the rules of Aristotle and Horace. Crites is the one who opens the discussion by defending the superiority of ancient drama over modern plays.
Therefore, the correct answer is Crites (2) because he is the one who advocates for the Ancients at the beginning of the debate.
