Strabo, Geography

The parts situated next to this region towards the south as far as the Taurus are so inwoven with one another that the Phrygian and the Carian and the Lydian parts, as also those of the Mysians, since they merge into one another, are hard to distinguish. To this confusion no little has been contributed by the fact that the Romans did not divide them according to tribes, but in another way organized their jurisdictions, within which they hold their popular assemblies and their courts. Mt. Tmolus is a quite contracted mass of mountain and has only a moderate circumference, its limits lying within the territory of the Lydians themselves; but the Mesogis extends in the opposite direction as far as Mycale, beginning at Celaenae, according to Theopompus. And therefore some parts of it are occupied by the Phrygians, I mean the parts near Celaenae and Apameia, and other parts by Mysians and Lydians, and other parts by Carians and Ionians. So, also, the rivers, particularly the Maeander, form the boundary between some of the tribes, but in cases where they flow through the middle of countries they make accurate distinction difficult. And the same is to be said of the plains that are situated on either side of the mountainous territory and of the river-land. Neither should I, perhaps, attend to such matters as closely as a surveyor must, but sketch them only so far as they have been transmitted by my predecessors.
