"The Iliad of Homer" by Homer is an ancient Greek epic poem composed around the late 8th or early 7th century BC. Set during the final weeks of the decade-long Trojan War, it traces the devastating anger of Achilles, the greatest Greek warrior, sparked by a fierce quarrel with King Agamemnon. As pride and wrath drive the conflict, the poem moves between sweeping battlefield scenes and intimate human moments, while the Olympian gods themselves intervene in mortal affairs, shaping the fates of heroes and determining the destiny of Troy.
