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
As things stood, it
was really necessary at once to put an end to such a freedom, equally
pitiful and pernicious, by means of a superior power permanently
present on the spot; the feeble policy of sentiment, with all its
apparent humanity, was far more cruel than the sternest occupation
would have been.
In Boeotia for instance Rome had, if not to
instigate, at least to permit, a political murder, because the Romans
had resolved to withdraw their troops from Greece and, consequently,
could not prevent the Greeks friendly to Rome from seeking their
remedy in the usual manner of the country. But Rome herself also
suffered from the effects of this indecision.
The war with Antiochus
would not have arisen but for the political blunder of liberating
Greece, and it would not have been dangerous but tor the military
blunder of withdrawing the garrisons from the principal fortresses on
the European frontier. History has a Nemesis for every sin--for an
impotent craving after freedom, as well as for an injudicious
generosity.
