What is now called Middle Albania, the Illyrian territory imme- diately north of Epirus, is much superior to the latter in produc- tiveness. 1 Though mountainous, it possesses more both of low hill and valley, and ampler as well as more fertile cultivable spaces. Epidamnus and Apollonia formed the seaports of this territory, and the commerce with the southern Illyrians, less barbarous than the northern, was one of the sources 2 of their great prosperity during the first century of their existence, a prosperity inter rupted in the case of the Epidamnians by internal dissensions, which impaired their ascendency over their Illyrian neighbors, and ultimately placed them at variance with their mother-city Korkyra. The commerce between these Greek seaports and the interior tribes, when once the former became strong enough to rtndei violent attack from the latter hopeless, was reciprocally beneficial tc both of them. Grecian oil and wine were introduced among these barbarians, whose chiefs at the same time learned to appreciate the woven fabrics, 3 the polished and carved me- tallic work, the tempered weapons, and the pottery, which issued from Grecian artisans. Moreover, the importation sometimes of salt-fish, and always that of salt itself, was of the greatest impor- tance to these inland residents, especially for such localities as possessed lakes abounding in fish, like that of Lychnidus.
