Alexander's letter to Persian king Darius in response to a truce plea:

" ...Your ancestors came to Macedonia and the rest of Hellas and did us great harm, though we had done them no prior injury. I have been appointed leader of the Greeks, and wanting to punish the Persians I have come to Asia, which I took from you..."

Arrian, Anabasis of Alexander II, 14, 4 (Loeb, P. A. Brunt) - Arrianos II (Anabasis) Historian, 95-175 AD


ALEXANDER OF MAKEDON I:

Had I not greatly at heart the common welfare of Greece, I should not have come to tell you; but I am myself a Greek by descent, and I would not willingly see Greece exchange freedom for slavery.

Herodotus Book IX ,45,(Kalliopi

"The deluge in the time of Deucalion, for instance, took place chiefly in the Greek world and in it especially about ancient Hellas, the country about Dodona and the Achelous, a river which has often changed its course. Here the Selli dwelt and those who were formerly called Graeci and now Hellenes."
Aristotle in Meteorologica

XIII. "...Thus the ambassador of Pyrrhus returned; and, when Pyrrhus asked him "what kind of a place he had found Rome to be," Cineas replied, that "he had seen a country of kings, for that all there were such, as Pyrrhus alone was thought to be in Epirus and the rest of Greece."
Eutropius (Abridgment of Roman History) Historiae Romanae Breviarium

"Greece starts at Oricus and the most ancient part of Greece is Epirus."

"We know of no Greek before Pyrros who fought against Rome."
Pausanias, 1.11

"It was for this reason that Pyrrhus was defeated by the Romans also in a battle to the finish. For it was no mean or untrained army that he had, but the mightiest of those then in existence among the Greeks and one that had fought a great many wars; nor was it a small body of men that was then arrayed under him, but even three times as large as his adversary's, nor was its general any chance leader, but rather the man whom all admit to have been the greatest of all the generals who flourish at that same period;"
Dionysius of Halicarnnasus, Roman Antiquities, 19.11

"The Molotti also were Epirote, and were subjects of Pyrrhus Neoptolemus, the son of Achilles, and of his descendants, who were Thessalians. The rest were governed by native princes. Some tribes were continually endeavouring to obtain the mastery over the others, but all were finally subdued by the Macedonians, except a few situated above the Ionian Gulf."
Strabo, 7.7.1

"Theopompus knew fourteen Epirote tribes, speakers of a strong west-Greek dialect, of which the Chaones held the plain of Buthrotum, the Thesproti the plain of Acheron, and the Molossi the plain of Dodona, which forms the highland centre of Epirus with an outlet southwards to Ambracia. "
