The Aeneid is a Latin epic poem written by Virgil in the 1st century BC (between 29 and 19 BC) that tells the legendary story of Aeneas, a Trojan who traveled to Italy, where he became the ancestor of the Romans. It is written in dactylic hexameter. The first six of the poem's twelve books tell the story of Aeneas' wanderings from Troy to Italy, and the poem's second half treats the Trojans' ultimately victorious war upon the Latins, under whose name Aeneas and his Trojan followers are destined to be subsumed.The hero Aeneas was already known to Greco-Roman legend and myth, having been a character in the Iliad; Virgil took the disconnected tales of Aeneas' wanderings, his vague association with the foundation of Rome and a personage of no fixed characteristics other than a scrupulous piety, and fashioned this into a compelling founding myth or nationalist epic that at once tied Rome to the legends of Troy, glorified traditional Roman virtues and legitimized the Julio-Claudian dynasty
