Aeneid and Odyssey both appear as heroic and adventurous characters. They pass though many obstacles to reach their fate and peace. One of the differences between them is that Aeneid is forced to leave his home and Odyssey is forced to go back home. These journeys tells a lot about these two heroes. The Gods play with them in similar ways throwing them to the edges of death and giving them tools to facilitate their trips. I believe Virgil chose to depict Aeneid the way he did, in order to introduce the reader with a better version of Odyssey. Aeneid had everything we wished Odyssey had while reading The Odyssey; true love for his family, honesty and determination. Odyssey never really showed to much ego to go back to his family. We can question his honesty because of the way he planed to to enter and conquer Troy and the many times he cheated on his wife. Also, Odyssey, even though he was on his way home, he never seemed to settle with that idea in his head.
In my opinion Aeneid is a hero and a better one.
I like your answer to the question. Aeneid was able to fight to the death. Their tales of heroism are different as Odysseus longed for wife while Aeneid was accused of the result of the war.
