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 long-discussed offensive alliance between Carthage and Macedonia
had been delayed, first by the sudden death of Antigonus, and then by
the indecision of his successor Philip and the unseasonable war waged
by him and his Greek allies against the Aetolians (534-537).
It
was only now, after the battle of Cannae, that Demetrius of Pharos
found Philip disposed to listen to his proposal to cede to Macedonia
his Illyrian possessions--which it was necessary, no doubt, to wrest
in the first place from the Romans--and it was only now that the court
of Pella came to terms with Carthage.
Macedonia undertook to land an
invading army on the east coast of Italy, in return for which she
received an assurance that the Roman possessions in Epirus should
be restored to her.
