Final answer:
Hector runs from Achilles out of fear and recognition of his superior strength, while Turnus' flight from Aeneas involves strategic maneuvering. Both instances show vulnerability in heroic characters within the context of their epic stories, subtly influenced by destiny and personal honor.
Step-by-step explanation:
Why does Hector run from Achilles? The story of the Iliad tells us that Hector, Trojan prince and a great warrior, flees from Achilles primarily because he is overwhelmed by the Greek hero's might and fears certain death. Hector's actions contrast with the later Roman epic of the Aeneid, where Turnus flees from Aeneas during their duel. This act is more about strategy and seeking an advantage rather than an act of pure fear.
In both instances, running demonstrates a moment of vulnerability for these otherwise heroic figures. However, in the ancient texts, running does not solely indicate cowardice but can also reflect tactical retreat or the overwhelming fate that faces the characters in these epic narratives. While Hector's run seems to be motivated by fear and an acknowledgement of Achilles' superiority, Turnus' retreat is more nuanced, involving elements of strategy against Aeneas, who is similarly favored by the gods.
The examples of Hector and Turnus emphasize the tragic nature of such heroes within their respective narratives of the Trojan War and the founding of Rome, reflecting the influence of destiny and the characters' complex relationships with honor and survival.
