Final answer:
The statement is false; the fullest narrative about Aeneas is found in Virgil's epic poem, the Aeneid, not in Livy's 'From the Foundation of the City'. Aeneas's story is central to Roman founding myths which historically framed the origins and conduct of the Roman people.
Step-by-step explanation:
False. The most extensive narrative about Aeneas is not found in Titus Livy's 'From the Foundation of the City' but rather in Virgil's epic poem, the Aeneid. Livy's work deals with the history of Rome and, while it does touch upon the legend of Aeneas, the fullest account of Aeneas's life and his role in the foundation of Roman culture is the central theme of the Aeneid.
The founding myths of Rome, including those about Aeneas and the Trojans who survived the sack of Troy, were used by Roman historians to justify Rome's historical periods of violence and civil war. These myths, especially those that recount the foundation of Rome, have been passed down throughout history, explaining the origins of Rome and the Roman people in relation to legendary and often violent episodes.
