classical unity

Noun

 * 1)  Any of the three rules for drama derived from Aristotle's Poetics: unity of action (a play should have one action that it follows, with minimal subplots), unity of time (the action should occur over a period of no more than 24 hours), and unity of place (a play should exist in a single physical space and should not attempt to compress geography, nor should the stage represent more than one place).
