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
Father and mother, sons and daughters, home and homestead,
servants and chattels--such are the natural elements constituting
the household in all cases, where polygamy has not obliterated the
distinctive position of the mother. But the nations that have been
most susceptible of culture have diverged widely from each other
in their conception and treatment of the natural distinctions which
the household thus presents. By some they have been apprehended
and wrought out more profoundly, by others more superficially;
by some more under their moral, by others more under their legal
aspects. None has equalled the Roman in the simple but inexorable
embodiment in law of the principles pointed out by nature herself.
