Vulnerability of Demigods

The few demigods, such as Aineias, who receive miraculous rescue [in the Iliad] are saved only by the direct intervention of a patron divinity, not by any special ingredient of their own semidivine nature. The flesh of the demigods is wholly vulnerable, the blood is the blood of mortals, the pain of injury that of ordinary mortal men, as is the inevitability of death. Nothing the men have inherited from their divine parents is itself protective; what saves them is the physical removal from the danger of the battlefield. The vividly evoked vulnerability of demigods such as Aineias will also have bearing upon the nature, and limitations, of the epic’s most outstanding demigod—Achilles.
