"Agon" is a Greek-language term for a struggle or contest, as well as the name of a god who personified this concept. "In Ancient Greek drama, particularly Old Comedy (fifth century B.C.), agon refers to a contest or debate between two characters - the protagonist and the antagonist - in the highly structured Classical tragedies and dramas. The agon could also develop between an actor and the choir or between two actors with half of the chorus supporting each. Through the argument of opposing principles, the agon in these performances resembled the dialectic dialogues of Plato. The meaning of the term has escaped the circumscriptions of its classical origins to signify, more generally, the conflict on which a literary work turns."
The term "agony" derives from "agon".
