For the purpose of judging and examining plays, understanding genre enables clarity. In the Poetics, Aristotle (384-322 B.C.) defines tragedy as an imitation of a single, unified, action that is serious, complete, and has a certain magnitude. Tragedy deals with the fall of someone whose character is good, believable, and consistent; importantly, the fall is caused by an error or frailty (hamartia – tragic flaw) rather than a vice or depravity. Philosophies about fate, fortune, and circumstances may intersect with the misfortunes of the hero, but the ups and downs of life are related to the issue of free will (not destiny) in the settling of plot. It is at the point of free will that revenge tragedy takes a distinct generic turn.
