Ovid has completely ‘transformed’ the story of Aeneas in "Metamorphoses". It is as though so-called historic significance of "The Aeneid" was of little importance to him. Perhaps what Ovid was trying to accomplish by putting Aenea’s journey in the background of his own story was to show that any one author can choose to tell his/her version of a story and that there is no one true version of a story. Also, by bringing about new version of an old story, the old story’s accuracy can be questioned.
Ovid seemed to have wanted his readers not to compare him to Virgil (or Homer) but to put him into a new category of poetry. Ovid wants his readers to know the story of Aeneas so he/she can really see the distinctions between his poetry and the poetry of Virgil. Ovid wanted his poetry to be new and exciting.
