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 application of Mithradates to the peoples of the east
than to the kings. It was not difficult to represent the war

Luristan, the most celebrated and the richest shrine in the whole

of the rich temples of the province Elymais, whither the predatory
expeditions of the Syrian and Parthian kings were regularly
directed (Strabo, xvi. 744; Polyb, xxxi. 11. 1 Maccab. 6, etc.),
and probably this as the best known; on no account can
the allusion be to the temple of Comana or any shrine at all in
the kingdom of Pontus.
