What are the two reasons Hector left the battlefield and returned to Troy?
As Iliad 6 opens, the Greeks and Trojans have been fighting vigorously. As the Greeks begin to rally against the Trojans, the Trojan prophet Helenus advises Hector to head back toward the city, rally the Trojan troops, and make a stand before the city gates. Helenus also tells Hector to go into the city and ask his mother Hecabe (Hecuba) to make an offering and a vow of sacrifice to Athene.
While in Troy, Hector also encounters Paris and rouses him to battle. After leaving Paris' house, Hector searches out his wife Andromache. She pleads with Hector not to endanger his life and leave her a widow and their son an orphan. Hector, however, answers his wife with one of the more famous lines in the Iliad:
"Go home, and attend to your tasks, the loom and spindle, and see the maids work hard. War is a man’s concern, the business of every man in Ilium, and mine above all" (A.S. Kline translation)
After this heartfelt and tearful encounter with his wife, Hector meets Paris again and the two prepare to return to the battle.
