'Sing, O muse, of the rage of Achilles, son of Peleus', the opening words of Homer's Iliad, have a strong claim to be the opening words of Western literature. Whether Homer ever existed, and what role he played in the text's emergence out of oral tradition have been debated for centuries.
Although full of allusions to the wider story of the Trojan War, the Iliad focuses on the events of a few weeks, Achilles dispute with Agamemnon and his withdrawal from battle, the death of his comrade Patroclus, his duel with Hector, and the eventual restoration of Hector's body to his father Priam; a series of incidents driven by the central theme of Achilles' wrath.
The Catalogue of Ships in Book Two is remarkable for a portrait of the Greek world with significant correspondences to the historical reality of the late Bronze Age, hundreds of years before the poem is believed to have been written down in the 8th Century BC.
