Homer's Odyssey: The majority of the Odyssey is concerned with the travels of Odysseus and a smaller portion with the travels of Telemachus. The eventual return home is magnified in importance because it has been the goal of the journey, but home and domesticity, in a sense, are portrayed almost more as the realm of Penelope than of the male heroes. While the eventual return completes the story, it is the journey, with its exotic locales that hold our interest.
Homer's Iliad: The destination, as it were, of the Iliad, is the eventual triumph of the Greeks, but the story does not cover that. It only speaks of part of the journey, namely the episode of the wrath of Achilles, as is set forth in the opening of the poem:
"SING, O GODDESS, the anger of Achilles son of Peleus, that brought countless ills upon the Achaeans. Many a brave soul did it send hurrying down to Hades, and many a hero did it yield a prey to dogs and vultures, for so were the counsels of Jove fulfilled from the day on which the son of Atreus, king of men, and great Achilles, first fell out with one another."
