Classicist and literary critic Leonard Muellner has argued: “In a hierarchy established by a communal division based on the rules of exchange, a person’s social value is in view and at stake in every exchange in which he or she takes part. Moreover, a slight to a person’s authority or rank is the same thing as an offense against the rules of reciprocal exchange, which support and define that rank.” Based on this model, analyze the quarrel between Achilles and Agamemnon in the beginning of the Iliad. How does exchange in the Iliad break down, and how is it reestablished by the end of the epic?
