I get the impression that the Epics of Homer developed for some centuries as an oral tradition and were perhaps only redacted into their final form by someone we call Homer, whereas I get the impression that Virgil was personally composing his work from scratch, though drawing upon myth and tradition, and had in mind certain political agendas regarding Roman hegemony. I have nothing to base these hunches on, unless I were to do some google search and get lucky. I think imagine that oral traditions that evolve over centuries, and are recited around campfires perhaps, must have a lot more action packed "chase scenes", and there is a lot more Jungian archetypal activity taking place, whereas a cultured educated individual who is composing his own opus for an audience he knows may not have in mind a goal of such diversity and drama. I have not really looked closely at Virgil or Homer in almost 40 years. I may be quite mistaken in my views. But I offer you these half-baked impressions in case they give someone else some ideas. Of course, the answers are probably to be found at sparknotes.com.
As I think about it, works like Homer, or the Ramayan, evolving over centuries of oral tradition, are like rain forests. If you destroy a rain forest, you can never get it back I am told. There are only so many such oral traditions. You could not decide tomorrow to evolve a new one. The tribes of the earth were ravished of their innocence millenia ago. If a pine forest burns down, Smokey the Bear and his crew can plant another one. Hemingways and Faulkners and Pynchons and Martels are always coming down the pike. (Shades of Oz: "Lions and Tigers and Bears, Oh my!" "Falkners and Pynchons, Martels, go buy!") ... might as well help out Amazon with a plug... what serendipity! The Amazon IS a rain forest. I must be on the right track, er, path.
I talk about the Aenead a bit in this paper:
