I think something with Heracles, but I am unsure.
Heracles supposedly conquered Rome and freed a Titan.
Hesiod's Theogony and Aeschylus' Prometheus Unbound both tell that Heracles shot and killed the eagle that tortured Prometheus (which was his punishment by Zeus for stealing fire from the gods and giving it to mortals). Heracles freed the Titan from his chains and his torments. Prometheus then made predictions regarding further deeds of Heracles.
In ancient Roman religion and myth, Hercules was venerated as a divinized hero and incorporated into the legends of Rome's founding.
