I'd like to nominate
The Aeneid, by Virgil, the epic poem that tells the story of how Aeneas, a Trojan, fled Troy at the end of the war, and his wanderings and eventual arrival in Italy, where he became the ancestor of the Roman people.
I think Americans (can't answer for others) are less familiar with the stories of
The Aeneid than they are with the epic poems of Homer, but it's as compelling a story. For those who have been on the epic journey here at MR, it dovetails nicely.
