The epic recounts episodes from the Trojan War centered on the wrath of Achilles after a dispute with Agamemnon, which leads him to withdraw from battle and alters the Greeks’ fortunes. It interweaves pitched combats, single combats, and funeral rites with frequent divine interventions as gods take sides and shape outcomes. Extended speeches, catalogues of warriors, and vividly described skirmishes contrast personal honor, pride, and grief with the impersonal forces of fate and mortality. The poem alternates collective military action and intimate scenes of loss, exploring how anger and loyalty affect leadership, reputation, and the human cost of glory.
