The Romans in Macedonia and Thrace
But this very conversion of Macedonia into a province directly dependent on Rome gave to the relations of Rome with the peoples on the north-east greater importance, by imposing on the Romans the obligation of defending the everywhere exposed frontier on the north and east against the adjacent barbarian tribes; and in a similar way not long afterwards (621) the acquisition by Rome of the Thracian Chersonese (peninsula of Gallipoli) previously belonging to the kingdom of the Attalids devolved on the Romans the obligation hitherto resting on the kings of Pergamus to protect the Hellenes here against the Thracians.

In these regions the most powerful nation at that time was the great Celtic people, which according to the native tradition(10) had issued from its settlements on the Western Ocean and poured itself about the same time into the valley of the Po on the south of the main chain of the Alps and into the regions on the Upper Rhine and on the Danube to the north of that chain. Among their various tribes, both banks of the Upper Rhine were occupied by the powerful and rich Helvetii, who nowhere came into immediate contact with the Romans and so lived in peace and in treaty with them: at this time they seem to have stretched from the lake of Geneva to the river Main, and to have occupied the modern Switzerland, Suabia, and Franconia Adjacent to them dwelt the Boii, whose settlements were probably in the modern Bavaria and Bohemia.(11) To the south-east of these we meet with another Celtic stock, which made its appearance in Styria and Carinthia under the name of the Taurisci and afterwards of the
