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
If in addition the further law,
which Clodius had likewise already projected and purposed to introduce
when praetor in 702, should give to freedmen and to slaves living
in de facto possession of freedom the same political rights
with the freeborn, the author of all these brave improvements
of the constitution might declare his work complete, and as
a second Numa of freedom and equality might invite the sweet rabble
of the capital to see him celebrate high mass in honour of the arrival
of the democratic millennium in the temple of Liberty which he had
erected on the site of one of his burnings at the Palatine.
Of course these exertions in behalf of freedom did not exclude
a traffic in decrees of the burgesses; like Caesar himself, Caesar's ape
kept governorships and other posts great and small on sale
for the benefit of his fellow-citizens, and sold the sovereign rights
of the state for the benefit of subject kings and cities.
