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
Of course the regents agreed
to be pacified; they refused nobody pardon, for there was nobody
who was worth the trouble of making him an exception. That we may
see how suddenly the tone in aristocratic circles changed
after the resolutions of Luca became known, it is worth while
to compare the pamphlets given forth by Cicero shortly before
with the palinode which he caused to be issued to evince publicly
his repentance and his good intentions.(6)
6. This palinode is the still extant oration on the Provinces to
be assigned to the consuls of 699. It was delivered in the end of
May 698. The pieces contrasting with it are the orations for
Sestius and against Vatinius and that upon the opinion of
the Etruscan soothsayers, dating from the months of March and April,
in which the aristocratic regime is glorified to the best of his
ability and Caesar in particular is treated in a very cavalier
tone. It was but reasonable that Cicero should, as he himself
confesses (Ad Att. iv. 5, 1), be ashamed to transmit even to
intimate friends that attestation of his resumed allegiance.
