Strabo, Geography

The Rhodians, like the people of Halicarnassus and Cnidus and Cos, are Dorians; for of the Dorians who founded Megara after the death of Codrus, some remained there, others took part with Althaemenes the Argive in the colonization of Crete, and others were distributed to Rhodes and to the cities just now mentioned. But these events are later than those mentioned by Homer, for Cnidus and Halicarnassus were not yet in existence, although Rhodes and Cos were; but they were inhabited by Heracleidae. Now when Tlepolemus had grown to manhood,“he forthwith slew his own father's dear uncle, Licymnius, who was then growing old; and straightway he built him ships, and when he had gathered together a great host he went in flight.
”¹The poet then adds,“he came to Rhodes in his wanderings, where his people settled in three divisions by tribes;
”and he names the cities of that time,“Lindus, Ialysus, and Cameirus white with chalk,
”²the city of the Rhodians having not yet been founded. The poet, then, nowhere mentions Dorians by name here, but perhaps indicates Aeolians and Boeotians, if it be true that Heracles and Licymnius settled there. But if, as others say, Tlepolemus set forth from Argos and Tiryns, even so the colonization thence could not have been Dorian, for it must have taken place before the return of the Heracleidae. And of the Coans, also, Homer says,“ were led by Pheidippus and Antiphus, the two sons of lord Thessalus, son of Heracles
”³and these names indicate the Aeolian stock of people rather than the Dorian.
