The Albanians, it is possible, belonged to the same stock which produced the Dorian Greeks, and the most important and the most thoroughly known case of socially recognized homosexuality is that of Greece during its period of highest military as well as ethical and intellectual vigor. In this case, as in those already mentioned, the homosexual tendency was frequently regarded as having beneficial results, which caused it to be condoned, if not, indeed, fostered as a virtue. Plutarch repeated the old Greek statement that the Beotians, the Lacedemonians, and the Cretans were the most warlike stocks because they were the strongest in love; an army composed of loving homosexual couples, it was held, would be invincible. It appears that the Dorians introduced _paiderastia_, as the Greek form of homosexuality is termed, into Greece; they were the latest invaders, a vigorous mountain race from the northwest (the region including what is now Albania) who spread over the whole land, the islands, and Asia Minor, becoming the ruling race. Homosexuality was, of course, known before they came, but they made it honorable. Homer never mentions it, and it was not known as legitimate to the Æolians or the Ionians. Bethe, who has written a valuable study of Dorian _paiderastia_, states that the Dorians admitted a kind of homosexual marriage, and even had a kind of boy-marriage by capture, the scattered vestiges of this practice indicating, Bethe believes, that it was a general custom among the Dorians before the invasion of Greece. Such unions even received a kind of religions consecration. It was, moreover, shameful for a noble youth in Crete to have no lover; it spoke ill for his character. By _paiderastia_ a man propagated his virtues, as it were, in the youth he loved, implanting them by the act of intercourse. In its later Greek phases _paiderastia_ was associated less with war than with athletics; it was refined and intellectualized by poetry and philosophy. It cannot be doubted that both Æschylus and Sophocles cultivated boy-love, while its idealized presentation in the dialogues of Plato has caused it to be almost identified with his name; thus in the early _Charmides_ we have an attractive account of the youth who gives his name to the dialogue and the emotions he excites are described. But even in the early dialogues Plato only conditionally approved of the sexual side of _paiderastia_ and he condemned it altogether in the final _Laws_.[21]
