"The Iliad is an epic poem in dactylic hexameters, traditionally attributed to Homer. Set in the Trojan War, the ten-year siege of Ilium, by a coalition of Greek States, it tells of the battles and events during the weeks of a quarrel between King Agamemnon and the warrior Achilles. Although the story covers only a few weeks in the final year of the war, the Iliad mentions or alludes to many of the Greek legends about the siege" (Summary from Wikipedia)
