Virgil rewrites and emulates Homeric epic for his Roman audience
it looks both to a Trojan past and a Roman future
it has a comparable hero and subject matter
it uses the literary devices of Homer's epics, and it written in dactylic hexameters
all 3 epics have a hero
when we study Aeneas, we shall see how changed he is from the Homeric model, and what that tells us about the sort of hero relevant to Rome under Augustus
Virgil uses epithets, repeated phrases, parallel scenes and characters, and similes, all the same as Homer
the epithets used in the Aeneid are limited, and employed for the full force of their meaning, not for general colour or metrical purposes
Aeneas is good/devoted, and Dido is unfortunate or unhappy
Homer had only the oral tradition of other epics and folk-myths to drawn on
Virgil had the benefit of over 500 years of literature, and the influence of many writers is evident
among others, the Greek Callimachus for technical composition of the verse and intellectual sophistication; Catullus for technical skill in expressing emotions; the Greek Plato and Roman Lucretius for their philosophy; and Cicero for the rhetoric of the law courts
about 1/2 of Homer's epics are in the form of speeches, an opportunity for the bard not only to get into character as he delivers the speech, but to act out the story.
the bard had to entertain the audience
the recitation of the epic was a performance to be sung to musical accompaniment
Virgil's poem would be recited
A Roman would not contemplate the silent reading of a poem
the reading could be done by anyone with a copy of the text, at any time
there was no need for the devices that are in Homer as an aid to memory
Homer's dramatisation gave way to a more contemplative element in the Aeneid
there is more psychological depth to the characters
there are pauses in action where Virgil shares what is going on in the minds of his creations
the major difference is perhaps the purpose
Homer was telling stories of a timeless heroic world conjured up from legend
Virgil moves from fantasy to the real world, with appearances in book 6 of real Roman statesmen, and in book 8 of the city of Rome with the Tiber
