"Of the Nahua predecessors of the Toltecs in Mexico the Olmecs and Xicalancans were the most important. They were the forerunners of the great races that followed. According to Ixtlilxochitl, these people—which are conceded to be one—occupied the world in the third age; they came from the East in ships or barks to the land of Potonchan, which they commenced to populate."
3. The Abbé Brasseur de Bourbourg, in one of the notes of the Introduction of the "Popol Vuh," presents a very remarkable analogy between the kingdom of Xibalba, described in that work, and Atlantis. He says:
"Both countries are magnificent, exceedingly fertile, and abound in the precious metals. The empire of Atlantis was divided into ten kingdoms, governed by five couples of twin sons of Poseidon, the eldest being supreme over the others; and the ten constituted a tribunal that managed the affairs of the empire. Their descendants governed after them. The ten kings of Xibalba, who reigned (in couples) under Hun-Came and Vukub-Came (and who together constituted a grand council of the kingdom), certainly furnish curious points of comparison. And there is wanting neither a catastrophe—for Xibalba had a terrific inundation—nor the name of Atlas, of which the etymology is found only in the Nahuatl tongue: it comes from atl, water; and we know that a city of Atlan (near the water) still existed on the Atlantic side of the Isthmus of Panama at the time of the Conquest."
"In Yucatan the traditions all point to an Eastern and foreign origin for the race. The early writers report that the natives believe their ancestors to have crossed the sea by a passage which was opened for them." (Landa's "Relacion," p. 28.)
"It was also believed that part of the population came into the country from the West. Lizana says that the smaller portion, 'the little descent,' came from the East, while the greater portion, 'the great descent,' came from the West. Cogolluda considers the Eastern colony to have been the larger.… The culture-hero Zamna, the author of all civilization in Yucatan, is described as the teacher of letters, and the leader of the people from their ancient home.… He was the leader of a colony from the East." ("North Amer. of Antiq.," p. 229.)
