Atlantis, according to the story, perished in a terrible convulsion of nature, in which the whole island sank into the ocean with nearly all its inhabitants. Only a few persons escaped in ships and rafts to lands east and west of the catastrophe. Each of these separate survivors became, in the legend of his descendants, the solitary Noah or Coxcox of a tradition representing the destruction of an entire world. The Nahuatl legend helps out the theory of Atlantis to willing minds. The Noah of the Mexican tribes was Coxcox, who, with his wife Xochiquetzal, alone escaped the deluge. They took refuge in the hollow trunk of a cypress (_ahuehuete_), which floated upon the water, and stopped at last on top of a mountain of Culhuacan. They had many children, but all of them were dumb. The great spirit took pity on them, and sent a dove, who hastened to teach them to speak. Fifteen of the children succeeded in grasping the power of speech, and from these the Toltecs and Aztecs are descended. Another account describes a deluge in which men perished and were changed to fish; the earth disappeared, and the highest mountain tops were covered with water. But before this happened, one of the Nahua gods, called Tezcatlipoca, spoke to a man named Nata and his wife Nana, saying: "Do not busy yourselves any longer making _pulque_, but hollow out for yourselves a large boat of an _ahuehuete_ tree, and make your home in it when you see the waters rising to the sky." The Mexican historian, Ixtlilxochitl, has conceived that after the dispersion of the human race, which succeeded the attempt to build the Tower of Babel, seven Toltecs reached America, and became the parents of that race. Thus having learned of the Tower of Babel from his Catholic instructors, Ixtlilxochitl skilfully pieces the Hebrew legend upon the Toltec fabric. The friends of the Atlantis theory in like manner seize upon the universal fable of the deluge to weave into their tissue. It remains for every reader to decide for himself whether to regard these theories as the airy fabric of a vision, or made up out of the whole cloth. III. TOLTECS. A somewhat connected chain of events begins with the traditions of the Toltecs upon the plateau of Anahuac. Their farthest ancestors, they supposed, founded the city of Huehue-Tlapallan far to the north, perhaps on the shores of the Colorado River. There they lived from generation to generation, nobody knows how long, until great civil wars broke out in their nation, and a part, deserting their ancient homes, wandered down towards the south. This was in the year 544 of our era. [Illustration: COLUMN FROM TULA.]
