legendary from Virgil's account. Aeneas leads a group of survivors away from the city, among them his son Ascanius (also known as Iulus), his trumpeter Misenus, father Anchises, the healer Iapyx, his faithful sidekick Achates, and Mimas as a guide. His wife Creusa is killed during the sack of the city. Aeneas also carries the Lares and Penates of Troy, which the historical Romans claimed to preserve as guarantees of Rome's own security. The Trojan survivors escape with a number of ships, seeking to establish a new homeland elsewhere. They land in several nearby countries that prove inhospitable, and are finally told by an oracle that they must return to the land of their forebears. They first try to establish themselves in Crete, where Dardanus had once settled, but find it ravaged by the same plague that had driven Idomeneus away. They find the colony led by Helenus and Andromache, but decline to remain. After seven years they arrive in Carthage, where Aeneas has an affair with Queen Dido (since according to tradition Carthage was founded in 814 BC, the arrival of Trojan refugees a few hundred years earlier exposes chronological difficulties within the mythic tradition). Eventually the gods order Aeneas to continue onward, and he and his people arrive at the mouth of the Tiber River in Italy. Dido commits suicide, and Aeneas's betrayal of her was regarded as an element in the long enmity between Rome and Carthage that expressed itself in the Punic Wars and led to Roman hegemony. At Cumae, the Sibyl leads Aeneas on an archetypal descent to the underworld, where the shade of his dead father serves as a guide; this book of the Aeneid directly influenced Dante, who has Virgil act as his narrator's guide. Aeneas is given a vision of the future majesty of Rome, which it was his duty to found, and returns to the world of the living. He negotiates a settlement with the local king, Latinus, and was wed to his daughter, Lavinia. This triggered a war with other local tribes, which culminated in the founding of the settlement of Alba Longa, ruled by Aeneas and Lavinia's son Silvius. Roman myth attempted to reconcile two different founding myths: three hundred years later, in the more famous tradition, Romulus founded Rome after murdering his brother Remus. The Trojan origins of Rome became particularly important in the propaganda of Julius Caesar,
