717.] Are we obliged to explain these similarities to the Mexican tradition by supposing some ancient intercourse between these peoples, the arrival, for instance, and settlement on the highlands around Lake Titicaca, of some "Toltec" colony, as has been maintained by such able writers on Peruvian antiquities as Leonce Angrand and J.J.von Tschudi ?[1] I think not.

The great events of nature, day and night, storm and sunshine, are everywhere the same, and the impressions they produced on the minds of this race were the same, whether the scene was in the forests of the north temperate zone, amid the palms of the tropics, or on the lofty and barren plateaux of the Andes.

These impressions found utterance in similar myths, and were represented in art under similar forms.

It is, therefore, to the oneness of cause and of racial psychology, not to ancient migrations, that we must look to explain the identities of myth and representation that we find between such widely sundered nations.
