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
When Philip concluded his treaty with the Aetolians and Romans in
548-9, he seriously intended to make a lasting peace with Rome, and
to devote himself exclusively in future to the affairs of the east.
It admits of no doubt that he saw with regret the rapid subjugation of
Carthage; and it may be, that Hannibal hoped for a second declaration
of war from Macedonia, and that Philip secretly reinforced the last
Carthaginian army with mercenaries.(2)
But the tedious affairs in
which he had meanwhile involved himself in the east, as well as the
nature of the alleged support, and especially the total silence of the
Romans as to such a breach of the peace while they were searching for
grounds of war, place it beyond doubt, that Philip was by no means
disposed in 551 to make up for what he ought to have done ten years
before. He had turned his eyes to an entirely different quarter.
