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
After the capitulation a large portion of the inhabitants fell
by their own hand--the mercy of the victor consisted in allowing the
Abydenes a term of three days to die voluntarily. Here, in the camp
before Abydus. the Roman embassy, which after the termination of its
business in Syria and Egypt had visited and dealt with the minor Greek
states, met with the king, and submitted the proposals which it had
been charged to make by the senate, viz. that the king should wage no
aggressive war against any Greek state, should restore the possessions
which he had wrested from Ptolemy, and should consent to an
arbitration regarding the injury inflicted on the Pergamenes and
Rhodians.
The object of the senate, which sought to provoke the king
to a formal declaration of war, was not gained; the Roman ambassador,
Marcus Aemilius Lepidus, obtained from the king nothing but the polite
reply that he would excuse what the envoy had said because he was
young, handsome, and a Roman.
