I want to know the answer to the following question:
Who guides Aeneas through the Underworld?
All the background I'm provided with is that "Jupiter in Book 4 recalls the lingering Aeneas to his duty to found a new city, and he slips away from Carthage, leaving Dido to commit suicide, cursing Aeneas and calling down revenge in a symbolic anticipation of the fierce wars between Carthage and Rome.". Is that enough to answer the question?
