Macedonia is bounded, first, on the west, by the coastline of the Adrias; secondly, on the east, by the meridian line which is parallel to this coastline and runs through the outlets of the Nebrus River and through the city Cypsela; thirdly, on the north, by the imaginary straight line which runs through the Bertiscus Mountain,1
and the Haemus;5
for these mountains, beginning at the Adrias, extend on a straight line as far as the Euxine, thus forming towards the south a great peninsula which comprises Thrace together with Macedonia, Epeirus, and Achaea; and fourthly, on the south, by the Egnatian Road,6
which runs from the city Dyrrhachium towards the east as far as Thessaloniceia. And thus7
the shape of Macedonia is very nearly that of a parallelogram.
