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
Caesar had no choice. He was from the outset and very earnestly
a democrat; the monarchy as he understood it differed more outwardly
than in reality from the Gracchan government of the people;
and he was too magnanimous and too profound a statesman to conceal
his colours and to fight under any other escutcheon than his own.
The immediate advantage no doubt, which this battle-cry brought to him,
was trifling; it was confined mainly to the circumstance
that he was thereby relieved from the inconvenience of directly naming
the kingly office, and so alarming the mass of the lukewarm
and his own adherents by that detested word.
The democratic banner
hardly yielded farther positive gain, since the ideals of Gracchus
had been rendered infamous and ridiculous by Clodius;
for where was there now--laying aside perhaps the Transpadanes--
any class of any sort of importance, which would have been induced
by the battle-cries of the democracy to take part in the struggle?
