So vital and so deep-seated in the hearts of the common-folk are these religious tendencies, that even at the present day when the word ‘Christian’ has become a popular synonym for ‘Greek’ in contradistinction not only with ‘Mohammedan,’ but even sometimes with ‘Western’ or ‘Catholic’ or with ‘Protestant,’ and when horror would be excited by any imputation of polytheism, there are yet recognised a large number of superhuman and for the most part immortal beings, whom the Church has been able neither to eradicate from the popular mind nor yet to incorporate under the form of saints or devils in her own theological system. These beings, whether benignant to man or maleficent, are all treated as divine. In ancient times the common people had probably little appreciation of the various grades of divinity; indeed it was one of the seven sages, we are told, who first differentiated God and the lesser deities and the heroes[108]; and at the present day the common-folk are certainly no more subtle of understanding than they were then. God and the Saints and these pagan powers are all feared and worshipped in the several ways traditionally suited to each; but the fact of worship proclaims them all alike to be gods. The origin of the non-Christian deities, even if we were unable to identify any of them with the gods of classical Greece, would be clearly enough proved by some of the general terms under which all of them are included. Those who use these terms indeed no longer appreciate their significance; for all sense of antagonism between the pagan and Christian elements in the popular religion has, as we have seen, long been lost. But the words themselves are a relic of the early days in which the combat of Christianity with the heathen world was still stern. Among the most widespread of these terms is the word ξωτικά[109] (i.e. ἐξωτικά), the ‘extraneous’ powers, clearly an invention of the early Christians. The phrase ‘those that are without’ (οἱ ἔξω or οἱ ἔξωθεν) was used by S. Paul first[110] and afterwards generally by the Fathers of the Church to denote men of all other persuasions. In the fourth century Basil of Caesarea employed the adjective ἐξωτικός also in a corresponding sense[111]. This word no doubt became popular, and hence τὰ ἐξωτικά, ‘the extraneous ones,’ became a convenient term by which to denote comprehensively all those old divinities whose worship the Church disallowed but even among her own adherents could not wholly suppress. Another comprehensive term equally significant, if not so commonly used, is τὰ παγανά[112], ‘the pagan ones.’ This is in use in the Ionian islands and some parts of the mainland, but I have not met with it nor found it understood in the Peloponnese or in the islands of the Aegean Sea[113]. In Cephalonia it is chiefly, though not exclusively, applied to a species of supernatural beings usually called callicántzari (καλλικάντζαροι) of whom more anon: the reason of this restriction may be either the fact
