The Aeneid

The hero Aeneas was already known to Greco-Roman legend and myth, having been a character in the Iliad, composed in the 8th century BC. 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 national epic that at once tied Rome to the legends of Troy, explained the Punic wars, glorified traditional Roman virtues and legitimized the Julio-Claudian dynasty as descendants of the founders, heroes and gods of Rome and Troy.
