Does it seem hardly credible that popular tradition should still faithfully record a superstition which dates from before Homer and yet is practically ignored by Greek literature? Still if the fidelity of the common-folk’s memory is guaranteed in many details by its agreement with that which literature does record, it would be folly to disregard it where literature is silent or prefers another of the still prevalent traditions. Let us take only Apollodorus’ account[658] of the fight of Heracles with the Centaurs and mark the several points in which it confirms the present beliefs about the Callicantzari. The old home, he says, of the Centaurs before they came to Malea was Pelion; Pelion is now the place where above all others stories of the Callicantzari are rife; and in the neighbouring island of Sciathos it is believed[659] that they come at Christmas not from the lower world, but from the mainland, the old country of the Magnetes; even local associations then seem to have survived, just as in the modern stories about Demeter from Eleusis and from Phigaleia. Heracles was entertained in the cave of the Centaur Pholos; the Callicantzari likewise live in caves during their sojourn on earth, and their hospitality, though never sought, has been endured. The Centaur Pholos ate raw meat, though he provided his guest with cooked meat; the Callicantzari also regale themselves on uncooked food[660], toads and snakes for the most part, but in one Messenian story also raw dogs’-flesh[661]. Heracles broached a cask of wine, and Pholos’ brother Centaurs smelt it and swarmed to the cave on mischief bent; the Callicantzari have the same love of wine and the same malevolence. The first of the Centaurs to enter the cave were put to flight by Heracles with fire-brands, and his ordinary weapon, the bow, was not used by him save to complete the rout; fire-brands are the right weapons with which to scare away the Callicantzari. Surely, when such correspondences as these attest the integrity of popular tradition for some two thousand years, there is nothing incredible in the supposition that there had been equal integrity in popular (as opposed to artistic and literary) traditions for another thousand years or more before that. Thus then it appears that in some districts of modern Greece, in which there prevail the beliefs that the Callicantzari are, in their normal form, human and that they are capable of transforming themselves into beasts, popular tradition dates from the age in which the Achaean invaders credited the Pelasgian tribe of Centauri with magical powers and in token of one special manifestation thereof surnamed them Pheres.
