"We have already inferred from the incident at the Olympic Games c.500 that the Macedonians themselves, as opposed to their kings, were considered not to be Greeks. Herodotus said this clearly in four words, introducing Amyntas, who was king c.500, as ' a Greek ruling over Macedonians' (5.20. 4), and Thucydides described the Macedonians and other northern tribes as 'barbarians' in the sense of 'non-Greeks', despite the fact that they were Greek-speaking. (Thuc. 2. 80. 5-7; 2. 81. 6; 4. 124.1) When it comes to political controversy, it was naturally good invective to call the king a barbarian too. Thus a Greek speech-writer called the Thessalians 'Greeks' and Archelaus, the contemporary Macedonian king, 'a barbarian'. Demosthenes spoke of Philip II as 'the barbarian from Pella'. Writing in 346 and eager to win Philip's approval, Isocrates paid tribute to Philip as a blue-blooded Greek and made it clear at the same time that Macedonians were not Greeks. (Isoc. 5. 108 and 154) Aristotle, born at Stageira on the Macedonian border and the son of a Greek doctor at the Macedonian court, classed the Macedonians and their institution of Monarchy as not Greek, as we shall see shortly. It is thus not surprising that the Macedonians considered themselves to be, and were treated by Alexander the Great as being, separate from the Greeks. They were proud to be so."
[Interesting (inadvertent) reversals in Hammond narrative: "Philip and Alexander attracted many able foreigners, especially Greeks, to their service, and many of these were made Companions (e.g., Nearchus a Cretan, Eumenes a citizen of Cardia, and Sitalces a member of the Odrysian royal family). Some of them, if they served in the King's Army, were given Macedonian citizenship, which apparently was in the gift of the king." p. 141]
"These instances show us that even Philip II and Alexander III introduced very few Greeks into the Assembly of Macedones. They wanted the 'Macedones' to have their own esprit de corps; and those of them who came from Lower Macedonia continued to speak the Macedonian dialect among themselves and to address the king or a commander in that dialect as a sign of affection."
53-an ordinary soldier is represented as speaking in the Macedonian dialect to the dying Alexander in Ps-Callisthenes B 32. 14 (ed. Kroll), and the Macedonian soldiers greeted Eumenes in the Macedonian dialect when he came to command them (Plu. Eum. 14. 11). [p.64]
"The name of the ancient Macedonians is derived from Macedon, who was the grandchild of Deukalion, the father of all Greeks. This we may infer from Hesiod's genealogy. It may be proven that Macedonians spoke Greek since Macedon, the ancestor of Macedonians, was a brother of Magnes, the ancestor of Thessalians, who spoke Greek." [Professor Nicholas Hammond, University of Cambridge, 1993]
As you probably know, there were many tribes in Macedonia. If we accept Macedon to be the progenitor of his tribe, where is the connection for the rest of the Macedonian tribes? What about the Lynchestians, Elimiotes, Eordians, Orestians etc. Besides, in the 'Catalogue of Women', the eponimous founder of Makedonia, Makedon, was the son of Zeus and Deukalion's daughter Thuia. This line of descent EXCLUDES him from the Hellenic genealogy - and hence, by implication, the Macedonians from the ranks of Hellenism." [Ethnic Identity in Greek Antiquity, by J. Hall, p.64]
