What then of the other part of that conclusion? There is ancient proof that the Callicantzari were originally men; but what witness is there to the metamorphosis of those men into beasts? The Centaurs’ alternative name, Pheres.
An ethnological explanation of this name has recently been put forward by Prof. Ridgeway[641]. Concluding from the evidence of the _Iliad_ that ‘the Pheres are as yet nothing more than a mountain tribe and are not yet conceived as half-horse half-man,’ he points out, on the authority of Pindar, that Pelion was the country of the Magnetes[642] and that Chiron not only dwelt in a cave on Pelion, but is himself called a Magnete[643]. ‘It is then probable,’ he continues[644], ‘that the Centaur myth originated in the fact that the older race (the Pelasgians) had continued to hold out in the mountains, ever the last refuge of the remnants of conquered races. At first the tribes of Pelion may have been friendly to the (Achaean) invader who was engaged in subjugating other tribes with whom they had old feuds; and as the Norman settlers in Ireland gave their sons to be fostered by the native Irish, so the Achaean Peleus entrusted his son to the old Chiron. Nor must it be forgotten that conquering races frequently regard the conquered both with respect and aversion. They respect them for their skill as wizards, because the older race are familiar with the spirits of the land.... On the other hand, as the older race have been driven into the most barren parts of the land, and are being continually pressed still further back, and have their women carried off, they naturally lose no opportunity of making reprisals on their enemies, and sally forth from their homes in the mountains or forests to plunder and in their turn to carry off women. The conquering race consequently regard the aborigines with hatred, and impute to them every evil quality, though when it is necessary to employ sorcery they will always resort to one of the hated race.’
Then follow a series of instances from various parts of the world which amply justify this estimate of the relations between conquerors and conquered. But in applying the principle thus obtained to the case of the Centaurs Prof. Ridgeway goes a little further. ‘As it is therefore certain that aboriginal tribes who survive in mountains and forests are considered not only possessed of skill in magic, but as also bestial in their lusts, _and are even transformed into vipers and wild beasts by the imagination of their enemies_, we may reasonably infer from the Centaur myth that the ancient Pelasgian tribes of Pelion and Ossa had been able to defy the invaders of Thessaly, and that they had from the remotest times possessed these mountains.
