I just found this too
2. To what extent is the Aeneid a political poem? Is it propaganda?
The Aeneid’s main purpose is to create a myth of origins that consolidates Rome’s historical and cultural identity. This search for origins of a race or culture is a political endeavor, in that it seeks to justify the Roman Empire’s existence and to glorify the empire through the poem’s greatness. Yet the Aeneid is also an artistic endeavor, and therefore to dismiss the poem as mere propaganda is to ignore its obvious artistic merit.
In many of the passages referring explicitly to the emperor Augustus—in Anchises’s presentation of the future of Rome, for example—Virgil’s language suggests an honest and heartfelt appreciation of Augustus’s greatness. It is worth noting, however, that in addition to being the emperor, Augustus was also Virgil’s patron. It would thus have been impossible for Virgil to criticize him outright in his work. One can argue that Virgil may not have truly believed in Augustus’s greatness and that the impossibility of explicit criticism forced him to resort to subtle irony in order to air any grievances regarding Augustus’s policies or ideology.
