There may however be some who, while admitting that mere lapse of time need not have extinguished ancient Hellenic ideas, will be disposed to question the likelihood, even the possibility, of their transmission on racial grounds. The belief in the evil eye and the practice of sympathetic magic were once, they may say, the common property of the whole uncivilised world; and though the inhabitants of modern Greece have inherited these old superstitions and usages, there is nothing to show from what ancestry they have received the inheritance. The population, it may be urged, has changed; the Greeks of to-day are not Hellenes; their blood has been contaminated by foreign admixture, and with this admixture may have come external, non-Hellenic traditions; has not Fallmerayer stoutly maintained that the modern inhabitants of Greece have practically no claim to the name of Hellenes, but come of a stock Slavonic in the main, though cross-bred with the offscourings of many peoples? The historical facts from which Fallmerayer argued are not to be slighted. It is well established[37] that, from the middle of the sixth century onwards, successive hordes of Slavonic invaders swept over Greece, driving such of the native population as escaped destruction into the more mountainous or remote districts; that in the middle of the eighth century, when the numbers of the Greek population had been further reduced by the great pestilence of 746, ‘the whole country,’ to use the exact phrase of Constantine Porphyrogenitus[38], ‘became Slavonic and was occupied by foreigners’; that the Slavonic supremacy lasted at least until the end of the tenth century; that thereafter a gradual fusion of the remnants of the Greek population with their conquerors began, but proceeded so slowly that at the beginning of the thirteenth century the ‘Franks,’ as the warriors of Western Christendom were popularly called, found Slavonic tribes in Elis and Laconia quite detached from the rest of the population, acknowledging indeed the supremacy of the Byzantine government, but still employing their own language and their own laws; and finally that the amalgamation of the two races was not complete even by the middle of the fifteenth century, for the Turks at their conquest of Greece found several tribes of the Peloponnese, especially in the neighbourhood of Mount Taygetus, still speaking a Slavonic tongue.
