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 "On reaching Cumae, in Italy in Book 6, Aeneas consults the Cumaean Sibyl, who conducts him through the Underworld where Aeneas meets the dead Anchises who reveals Rome's destiny to his son.". Is that enough to answer the question?
