What is the theme in Classicism by ?

Order is a theme in the book. Classic Greek and Roman writers also influenced the works of the later Classicists in their preference for order over chaos. Symmetry, continuity, smoothness, harmony, and logic were all characteristics classical writers would strive for in their works. The unities are an example or an outgrowth of this need for structure and for order. They are strict rules of dramatic structure formulated by Renaissance dramatists on the basis of Aristotle's views of drama, as expressed in his work Poetics. Among them are the three unities of action, time, and place. According to these rules, a play first must have a single plot with a beginning, middle, and an ending. Second, the action of a play should be restricted to the events of a single day. Finally, the scene should be restricted to a single location.
