‘In the last lines of the poem he [Aeneas] killed Turnus, after relenting, just for revenge, in memory of Pallas, whom Turnus had killed, and because he saw the belt of Pallas, which Turnus was wearing. It was sheer vindictive vengeance. At the end of the Aeneid, Rome is sure; but we do not know that Dido would have liked the new Aeneas as much as the old.’ (Jackson Knight, Roman Vergil, p. 142.)
If the death of Turnus is an act of sheer vindictive vengeance which assures the foundation of Rome, then the Aeneid is, ultimately, a national epic, no less, but no more. Is this interpretation valid?
It is true that, after a moment of relenting in which the life of Turnus hangs in the balance, Aeneas sees the belt of Pallas, and, overcome with fury, kills Turnus. This is an act of vengeance, but what for?
The reference to the belt of Pallas leads us back to the tenth book. The death of Pallas at the hands of Turnus is described, not as an event of importance in itself, but in close parallelism and contrast to the death of young Lausus at the hands of Aeneas. These two deaths, which are the first outstanding events of the war, are carefully introduced: the book opens with a council of the gods, the return of Aeneas, a catalogue of the Etruscan forces which he is bringing with him, his encounter with the nymphs who warn him of the situation, and finally his landing.
