Neither Jews nor Aztecs, nor indeed any American nation, appear to have supposed, with some of the old philosophers, that the present was an exact repetition of previous cycles,[218-1] but rather that each was an improvement on the preceding, a step in endless progress. Nor did either connect these beliefs with astronomical reveries of a great year, defined by the return of the heavenly bodies to one relative position in the heavens. The latter seems characteristic of the realism of Europe, the former of the idealism of the Orient; both inconsistent with the meagre astronomy and more scanty metaphysics of the red race. The expectation of the end of the world is a natural complement to the belief in periodical destructions of our globe. As at certain times past the equipoise of nature was lost, and the elements breaking the chain of laws that bound them ran riot over the universe, involving all life in one mad havoc and desolation, so in the future we have to expect that day of doom, when the ocean tides shall obey no shore, but overwhelm the continents with their mountainous billows, or the fire, now chafing in volcanic craters and smoking springs, will leap forth on the forests and grassy meadows, wrapping all things in a winding sheet of flame, and melting the very elements with fervid heat. Then, in the language of the Norse prophetess, "shall the sun grow dark, the land sink in the waters, the bright stars be quenched, and high flames climb heaven itself."[218-2] These fearful foreboding shave[TN-9] cast their dark shadow on every literature. The seeress of the north does but paint in wilder colors the terrible pictures of Seneca,[219-1] and the sibyl of the capitol only re-echoes the inspired predictions of Malachi. Well has the Christian poet said:-- Dies iræ, dies illa, Solvet sæclum in favillâ, _Testis David cum Sibylâ_. Savage races, isolated in the impenetrable forests of another continent, could not escape this fearful looking for of destruction to come. It oppressed their souls like a weight of lead. On the last night of each cycle of fifty-two years, the Aztecs extinguished every fire, and proceeded, in solemn procession, to some sacred spot. Then the priests, with awe and trembling, sought to kindle a new fire by friction. Momentous was the endeavor, for did it fail, their fathers had taught them on the morrow no sun would rise, and darkness, death, and the waters would descend forever on this beautiful world.
