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 relations--
perplexing from the very nature of the case--of the rulers of
Pergamus towards the free or half-free commercial cities within
their kingdom, and towards their barbarous neighbours on its borders,
became complicated still more painfully by this ill humour on the part
of their patrons. As it was not clear whether, according to the
treaty of peace in 565, the heights of the Taurus in Pamphylia and
Pisidia belonged to the kingdom of Syria or to that of Pergamus,(29)
the brave Selgians, nominally recognizing, as it would seem, the Syrian
supremacy, made a prolonged and energetic resistance to the kings
Eumenes II and Attalus II in the hardly accessible mountains of
Pisidia.
