The Aenei (pronounced /əˈniːɪd/; in Latin Aeneis, pronounced [aɪˈne.ɪs] — the title is Greek in form: genitive case Aeneidos) 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.
