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
There was a Macedonian party in every city, and therefore
trials for high treason began in all parts of Greece. Whoever had
served in the army of Perseus was immediately executed, whoever was
compromised by the papers of the king or the statements of political
opponents who flocked to lodge informations, was despatched to Rome;
the Achaean Callicrates and the Aetolian Lyciscus distinguished
themselves in the trade of informers.
In this way the more
conspicuous patriots among the Thessalians, Aetolians, Acarnanians,
Lesbians and so forth, were removed from their native land; and,
in particular, more than a thousand Achaeans were thus disposed of
--a step taken with the view not so much of prosecuting those who were
carried off, as of silencing the childish opposition of the Greeks.
To the Achaeans, who, as usual, were not content till they got the
answer which they anticipated, the senate, wearied by constant
requests for the commencement of the investigation, at length roundly
declared that till further orders the persons concerned were to remain
in Italy.
