The Iliad is the first and the greatest literary achievement of Greek civilization - an epic poem without rival in the literature of the world, and the cornerstone of Western culture. The story centres on the critical events in the last year of the Trojan War, which lead to Achilleus' killing of Hektor and determine the fate of Troy. But Homer's theme is not simply war or heroism. With compassion and humanity, he presents a universal and tragic view of the world, of human life lived under the shadow of suffering and death, set against a vast and largely unpitying divine background.
