I want to know the answer to the following question:
Who is mercilessly slaughtered by Aeneas?
All the background I'm provided with is that "The Aeneid is full of prophecies about the future of Rome, the deeds of Augustus, his ancestors, and famous Romans, and the Carthaginian Wars; the shield of Aeneas even depicts Augustus' victory at Actium against Mark Antony and Cleopatra VII in 31 BC.". Is that enough to answer the question?
