“Homer's epic does not tell of such seemingly essential events as the abduction of Helen, for example, nor of the mustering and sailing of the Greek fleet, the first hostilities of the war, the Trojan Horse, and the sacking and burning of Troy. Instead, the 15,693 lines of Homer's Iliad describe the occurrences of a roughly two-week period in the tenth and final year of what had become a stalemated siege of Troy.”
