Almost exhaustive proof of the wholly indigenous nature of the American religions is offered by the existence of the ruins of the large centres of culture and civilisation which are found scattered through Yucatan and Peru. These civilisations preceded those of the Aztecs and Incas by a very considerable period, how long it is impossible in the present state of our knowledge of the subject to say. Those huge, buried cities, the Ninevehs and Thebeses of the West, have left not even a name, and of the peoples who dwelt in them we are almost wholly ignorant. That they were of a race cognate with the Aztecs and Toltecs appears probable when we take into account the similarity of design which their architecture bears to the later ruins of the Aztec structure. Yet there is equally strong evidence to the contrary. At what epoch in the history of the world these cities were erected it would at the present time be idle to speculate. The recent discovery of a buried city in the Panhandle region of Texas may throw some light upon this question, and indeed upon the dark places of American archæology as a whole. In the case of the buried cities of Uxmal and Palenqüe a great antiquity is generally agreed upon. Indeed one writer on the subject goes so far as to place their foundation at the beginning of the second Glacial Epoch! He sees in these ruins the remnants of a civilisation which flourished at a time when men, fleeing from the rigours of the glacial ice-cap, huddled for warmth in the more central parts of the earth. It is unnecessary to state that this is a wholly preposterous theory, but the fact that the ruins of Palenqüe are at the present time lost in the depths of a tropic forest goes far to prove their great antiquity. Arguing, then, from this antiquity, we may be justified in assuming that in these now buried cities the mythology of Mexico was partly evolved; that it was handed down to the Aztec conquerors who entered the country some four hundred years before its subjugation by Cortes, and that it received additions from the tribal deities. In the case of the Peruvian mythology we may argue a similar evolution, which, as we shall see later, had been spread over a considerably shorter period. CHAPTER II MEXICAN MYTHOLOGY
