Strabo, Geography

Now the first peoples he names in the Catalogue are those under Achilles, who occupied the southern side and were situated alongside Oeta and the Epicnemidian Locrians, “"all who dwelt in the Pelasgian Argos and those who inhabited Alus and Alope and Trachin, and those who held Phthia and also Hellas the land of fair women, and were called Myrmidons and Hellenes and Achaeans."
”¹with these he joins also the subjects of Phoenix, and makes the expedition common to both leaders. It is true that the poet nowhere mentions the Dolopian army in connection with the battles round Ilium, for he does not represent their leader Phoenix as going forth into the perils of battle either, any more than he does Nestor; yet others so state, as Pindar, for instance, who mentions Phoenix and then says, “"who held a throng of Dolopians, bold in the use of the sling and bringing aid to the missiles of the Danaans, tamers of horses."
”²This, in fact, is the interpretation which we must give to the Homeric passage according to the principle of silence, as the grammarians are wont to call it, for it would be ridiculous if the king Phoenix shared in the expedition “("I dwelt in the farthermost part of Phthia, being lord over the Dolopians")
”³⁴ without his subjects being present; for if they were not present, he would not have been regarded as sharing in the expedition with Achilles, but only as following him in the capacity of a chief over a few men and as a speaker, perhaps as a counsellor. Homer's verses⁵ on this subject mean also to make this clear, for such is the import of the words, “"to be a speaker of words and a doer of deeds."
”⁶Clearly, therefore, he means, as I have already said, that the forces under Achilles and Phoenix are the same. But the aforesaid statements concerning the places subject to Achilles are themselves under controversy. Some take the Pelasgian Argos as a Thessalian city once situated in the neighborhood of Larisa but now no longer existent; but others take it, not as a city, but as the plain of the Thessalians, which is referred to by this name because Abas, who brought a colony there from Argos, so named it.
