Talk not of flight, for I shall not listen to you: I am of a race that knows neither flight nor fear, and my limbs are as yet unwearied...Pallas Athena bids me be afraid of no man”(Iliad, V).
Homer’s depiction of Diomedes is that of a man fearless and hungry for war. Yet, Vergil’s version of Diomedes is in complete contradiction to Homer’s, in the Aeneid he has matured and is no longer wanting for war. Diomedes metamorphosis is made clear when he says to the emissaries,
