That evidence certainly receives much confirmation, positive and negative, from without. In the first place, though Hesiod supplies us with an Hellen, and with a Dorus and Æolus among his sons, he says not a word of an Ion; and the tradition connecting Ion with Hellen through Xuthus is of later date: probably later than Euripides, who makes Ion only the adopted son of Xuthus an Achæan[218], and the real son of Creusa, an Erectheid; with Apollo, a Hellic, but also a Pelasgian deity, for his father. Again, in the legendary times we do not hear of the Athenians as invaders and conquerors, which was the character of the Hellic tribes, but usually as themselves invaded; for example, by Eurystheus from the Peloponnesus. In ancient tradition generally, the Athenians appear on the defensive against Bœotians[219], Cretans, or others. And the reputed Pylian and Neleid descent of the Pisistratid family is a curious illustration of the manner in which Attica was reported to have imported from abroad the most energetic elements of her own population[220], and also of the (so to speak) natural predominance of Hellic over Pelasgic blood. Thucydides[221] informs us, that the Athenians were first among the Greeks to lay aside the custom of bearing arms, and to cultivate ease and luxury. Of this we have perhaps already had an indication in the words ἑλκεχίτωνες. He also states that, on account of the indifferent soil[222], which offered no temptation comparable to those supplied by the more fertile portions of Greece, there was no ejection of the inhabitants from Attica by stronger claimants. Τὴν γοῦν Ἀττικὴν, ἐκ τοῦ ἐπὶ πλεῖστον διὰ τὸ λεπτογέων ἀστασίαστον οὖσαν, ἄνθρωποι ᾤκουν οἱ αὐτοὶ ἀεί. This is simply stating in another form what was usually expressed by declaring them autochthons. It is part of their Pelasgian title.
