Please note that Mommsen uses the AUC chronology (Ab Urbe Condita), i.e. from the founding of the City of Rome. You can use this reference table to have the B.C. dates
All this was a sorry and unskilful patchwork. The view
that the original Penates of Rome were preserved not, as had hitherto
been believed, in their temple in the Roman Forum, but in the shrine
at Lavinium, could not but be offensive to the Romans; and the Greek
fiction was a still worse expedient, inasmuch as under it the gods
only bestowed on the grandson what they had adjudged to the grandsire.
But the redaction served its object: without exactly denying the
national origin of Rome, it yet deferred to the Hellenizing tendency,
and legalized in some degree that desire to claim kindred with Aeneas
and his descendants which was already at this epoch greatly in
vogue;(60) and thus it became the stereotyped, and was soon accepted
as the official, account of the origin of the mighty community.
