3. The writers subsequent to Homer do not assign the same boundaries, but introduce other names, and a greater number of territorial divisions. The Greek colonies were the cause of this; the Ionian migration produced less change, for it was further distant from the Troad, but the Æolian colonists occasioned it throughout, for they were dispersed over the whole of the country from Cyzicene as far as the Caïcus, and occupied besides the district between the Caïcus and the river Hermus. It is said that the Æolian preceded the Ionian migration four generations, but it was attended with delays, and the settlement of the colonies took up a longer time. Orestes was the leader of the colonists, and died in Arcadia. He was preceded by his son Penthilus, who advanced as far as Thrace, sixty years[1319] after the Trojan [CAS. 582] war, about the time of the return of the Heracleidæ to Peloponnesus. Then Archelaus the son of Penthilus conducted the Æolian colonies across the sea to the present Cyzicene, near Dascylium. Gras his youngest son proceeded as far as the river Granicus, and, being provided with better means, transported the greater part of those who composed the expedition to Lesbos, and took possession of it. On the other side, Cleuas, the son of Dorus, and Malaus, who were descendants of Agamemnon, assembled a body of men for an expedition about the same time as Penthilus, but the band of Penthilus passed over from Thrace into Asia before them; while the rest consumed much time near Locris, and the mountain Phricius. At last however they crossed the sea, and founded Cyme, to which they gave the name of Phriconis, from Phricius, the Locrian mountain. 4. The Æolians then were dispersed over the whole country, which we have said the poet calls the Trojan country. Later writers give this name to the whole, and others to a part, of Æolis; and so, with respect to Troja, some writers understand the whole, others only a part, of that country, not entirely agreeing with one another in anything. According to Homer, the commencement of the Troad is at the places on the Propontis, reckoning it from the Æsepus. According to Eudoxus, it begins from Priapus, and Artace, situated in the island of the Cyziceni opposite to Priapus, and thus he contracts the boundaries [of the Troad]. Damastes contracts them still more by reckoning its commencement from Parium.[1320] He extends the Troad as far as Lectum. But different writers assign different limits to this country. Charon of Lampsacus diminishes its extent by three hundred stadia more, by reckoning its commencement from Practius, for this is the distance between Parium and Practius, but protracts it to Adramyttium. It begins, according to Scylax of Caryanda, at Abydos. There is the same diversity of opinion respecting the boundaries of Æolis. Ephorus reckons its extent from Abydos to Cyme, but different writers compute it in different ways.
