Just as Rome itself claimed the favour of the gods, so did some individual Romans. In the mid-to-late Republican era, and probably much earlier, many of Rome's leading clans acknowledged a divine or semi-divine ancestor and laid personal claim to their favour and cult, along with a share of their divinity. Most notably in the very late Republic, the Julii claimed Venus Genetrix as ancestor; this would be one of many foundations for the Imperial cult. The claim was further elaborated and justified in Vergil's poetic, Imperial vision of the past.
