This document summarizes a debate between Eugenius and Crites on the relative merits of ancient versus modern poetry and drama. Crites argues that the ancients better followed rules of unity of time, place and action, while Eugenius contends that moderns have learned from but also improved upon the ancients, such as by dividing plays into acts and scenes. While they disagree on which era is superior, both acknowledge that values and customs have changed over time.
