Strabo Geography 12.8.3

[3] And the Lydians and the Maeonians, whom Homer calls the Mëiones, are in some way confused both with these peoples and with one another, because some say that they are the same and others that they are different; and they are confused with these people ¹ because some say that the Mysians were Thracians but others that they were Lydians, thus concurring with an ancient explanation given by Xanthus the Lydian and Menecrates of Elaea, who explain the origin of the name of the Mysians by saying that the oxya-tree is so named by the Lydians. ² And the oxya-tree abounds in the neighborhood of Mt. Olympus, where they say that the decimated persons were put out ³ and that their descendants were the Mysians of later times, so named after the oxya-tree, and that their language bears witness to this; for, they add, their language is, in a way, a mixture of the Lydian and the Phrygian languages, for the reason that, although they lived round Mt. Olympus for a time, yet when the Phrygians crossed over from Thrace and slew a ruler of Troy and of the country near it, those people took up their abode there, whereas the Mysians took up their abode above the sources of the Caïcus near Lydia.

[3] The Lydians also, and the Maeones, whom Homer calls Meones, are in some way confounded with these people and with one another; some authors say that they are the same, others that they are different, nations. Add to this that some writers regard the Mysians as Thracians, others as Lydians, according to an ancient tradition, which has been preserved by 8anthus the Lydian, and by Menecrates of Elaea, who assign as the origin of the name Mysians, that the Lydians call the beech-tree (Oxya) Mysos, which grows in great abundance near Olympus, where it is said decimated persons ¹ were exposed, whose descendants are the later Mysians, and received their appellation from the Mysos, or beech-tree growing in that country. The language also is an evidence of this. It is a mixture of Lydian and Phrygian words, for they lived some time in the neighbourhood of Olympus. But when the Phrygians passed over from Thrace, and put to death the chief of Troy and of the country near it, they settled here, but the Mysians established themselves above the sources of the Caïcus near Lydia.
