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
Men had become perplexed not merely as to
the old faith, but as to their very selves; the fearful crises of a
fifty years' revolution, the instinctive feeling that the civil war
was still far from being at an end, increased the anxious suspense,
the gloomy perplexity of the multitude.
Restlessly the wandering
imagination climbed every height and fathomed every abyss, where it
fancied that it might discover new prospects or new light amidst
the fatalities impending, might gain fresh hopes in the desperate
struggle against destiny, or perhaps might find merely fresh
alarms.
A portentous mysticism found in the general distraction--
political, economic, moral, religious--the soil which was adapted
for it, and grew with alarming rapidity; it was as if gigantic
trees had grown by night out of the earth, none knew whence
or whither, and this very marvellous rapidity of growth
worked new wonders and seized like an epidemic on all minds
not thoroughly fortified.
