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
The war with
Philip could not, after the withdrawal of the Aetolians, have been
carried on by the Romans without considerable exertions of their own;
and it appeared to them more convenient to terminate it also by a
peace, whereby the state of things before the war was substantially
restored and Rome in particular retained all her possessions on the
coast of Epirus except the worthless territory of the Atintanes.
Under the circumstances Philip had to deem himself fortunate in
obtaining such terms; but the fact proclaimed--what could not indeed
be longer concealed--that all the unspeakable misery which ten years
of a warfare waged with revolting inhumanity had brought upon Greece
had been endured in vain, and that the grand and just combination,
which Hannibal had projected and all Greece had for a moment joined,
was shattered irretrievably.
