There remain of Europe, first, Macedonia and the part of Thrace that are contiguous to it and extend as far as Byzantium; secondly, Greece; and thirdly, the Islands that are close by. Macedonia, of course, is a part of Greece, yet now, since I am following the nature and shape of the place geographically, I have decided to classify it apart from the rest of Greece and to join it with that part of Thrace.
