In a way, that's also a recognition that Dante needs Virgil and that the Inferno needs the Aeneid and that the epic needs a model and that for Dante to write this great poem he needs someone to come before him and he turns to Virgil's text, especially book six where Aeneas goes down into the underworld. And for me, that's a model of the poet's relationship to previous poetry, to another poetry as calling out for guidance.
