Critics of the Aeneid focus on a variety of issues. The tone of the poem as a whole is a particular matter of debate; some see the poem as ultimately pessimistic and politically subversive to the Augustan regime, while others view it as a celebration of the new imperial dynasty. Virgil makes use of the symbolism of the Augustan regime, and some scholars see strong associations between Augustus and Aeneas, the one as founder and the other as re-founder of Rome. A strong teleology, or drive towards a climax, has been detected in the poem. 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 in 31 BC. A further focus of study is the character of Aeneas. As the protagonist of the poem, Aeneas seems to constantly waver between his emotions and commitment to his prophetic duty to found Rome; critics note the breakdown of Aeneas's emotional control in the last sections of the poem where the "pious" and "righteous" Aeneas mercilessly slaughters Turnus.
The Aeneid appears to have been a great success. Virgil is said to have recited Books 2, 4 and 6 to Augustus; the mention of her son, Marcellus, in book 6 apparently caused Augustus' sister Octavia to faint. The poem was unfinished at Virgil's death in 19 BC.
