These tribes were the Xochimilcos, Cholcos, Tepanecos, Acolhuas, Tezcucans, Tlascaltecas and Astecs. For political strength the Astecs, Tezcucans and Tlascans formed a triumvirate, and each had their capital city, viz.: Tezcuco, Tlasca, and Tenochtitlan. The Astec clan in its peregrinations had kept the name _Astec_, in honor of their ancient home, _Aztlan_ or _Atlantis_, but their priest, Aacatl, decreed that they should be called _Mexicatls_, in honor of their war god, _Mexitli_, because he had enabled them to conquer their brethren. In the midst of the beautiful Lake Tezcuco, on an island, they built their national capital, Tenochtitlan, which the Spaniards called “the most beautiful spot on earth.” Cortez destroyed this beautiful city and built the modern city of Mexico on its ruins. It was here that the ill-starred “Moteuczoma”—whom the Spaniards have misspelled Montezuma—poured the wealth of his kingdom into the coffers of Cortez, and in return suffered the most humiliating degradation and death recorded on the pages of history. Tenochtitlan was a great city. Two thousand temples, one hundred palaces and a thousand sumptuous dwellings have melted before the desecrating Spaniards as a mirage before a thirsty traveler. The priests, in their too zealous zeal to uproot polytheism, wreaked their holy vengeance upon temples and idols; and history can produce no parallel to the vandalism that would sack the temples of all the written documents and ideographic paintings and make a bonfire of them on the public plaza, on the plea that they were from the devil! The zenith of New World civilization became a setting sun before a savage Christianity. The path of the Christian became a sirocco, the garden spot of the world became a holocaust. Tenochtitlan, the city of palaces, the capital of the Valley of Anahuac, was razed to the ground, and the testimony of a thousand years of civilization was as completely lost to the modern world as the buried island of Atlantis, and by a Christian nation! It matters little with which particular tribe of Anahuac the Mound-builders have become identified, since all the Nahuatl tribes were Mound-builders, and were forging a high civilization out of Nature herself.
