THE AENEID
A 12 book (chapter) heroic epic; left unfinished at the time of Virgil's death--technically, The Aeneid we now have is the rough draft Virgil worked on for 11 years!
It is considered by many to be the single most influential poem the history of Western civilization.
Influenced: Dante, Shakespeare, Milton, Spenser and many others.
Similar to Homer's The Odyssey (Homer acts as Virgil's muse): uses the themes of the wanderer (found in The Odyssey) and the hero in battle (found in The Iliad); uses "Homeric Phrasing" (i.e. similes, allusions, epithets, etc); Aeneas is most like Odysseus when he descends to the Underdworld.
