The answer is the Aeneid.
Virgil wrote it between 29 and 19 B.C.
It tells the tale of the Trojan hero Aeneas a character from the Illiad
who flees from Troy after it was conquered and their journey as they wander
from Troy to Italy where they had many adventures. Later they engage the Latins in war which
resulted in a victory for Aeneas and his people. Virgil’s poem gives a mythical origin of Rome
just like the myth of Romulus and Remus.
