Two considerable mercantile towns, Epidamnus or Dyrrachium (now Durazzo, 127), and Apollonia (near Avlona, about 167), were founded upon the portion of this coast nearest to Greece during the regal period of Rome; but no old Greek colony can be pointed out further to the north, with the exception perhaps of the insignificant settlement at Black Corcyra (Curzola, about 174 ?).

No adequate explanation has yet been given why the Greek colonization developed itself in this direction to so meagre an extent.

Nature herself appeared to direct the Hellenes thither, and in fact from the earliest times there existed a regular traffic to that region from Corinth and still more from the settlement at Corcyra (Corfu) founded not long after Rome (about 44); a traffic, which had as its emporia on the Italian coast the towns of Spina and Atria, situated at the mouth of the Po.

The storms of the Adriatic, the inhospitable character at least of the Illyrian coasts, and the barbarism of the natives are manifestly not in themselves sufficient to explain this fact.

But it was a circumstance fraught with the most momentous consequences for Italy, that the elements of civilization which came from the east did not exert their influence on its eastern provinces directly, but reached them only through the medium of those that lay to the west.
