In every Spanish description of the city we can see its resemblance to cities whose ruins are found farther south. If the Spaniards had invented the temple, they would not have made it unlike any thing they had ever before seen or heard of, by placing its altar on the summit of a high pyramid. This method of constructing temples is seen in the old ruins, but it was unknown to Cortez and his men until they found it in Mexico. The only reasonable or possible explanation of what they said of it is, that the temple actually existed at the Aztec capital, and that the Spaniards, being there, described what they saw. The uniform testimony of all who saw the country at that time shows that the edifices of towns and cities, wherever they went, were most commonly built of cut stone laid in mortar, or of timber, and that in the more rural districts thatch was frequently used for the roofs of dwellings. Moreover, we are told repeatedly that the Spaniards employed “Mexican masons,” and found them “very expert” in the arts of building and plastering. There is no good reason to doubt that the civilized condition of the country, when the Spaniards found it, was superior to what it has been at any time since the Conquest. WHO WERE THE AZTECS? The Mexicans, or Aztecs, subjugated by Cortez, were themselves invaders, whose extended dominion was probably less than two hundred and fifty years old, although they had been much longer in the Valley of Mexico. There were important portions of the country, especially at the south, to which their rule had not been extended. In several districts besides those of the Mayas and the Quichés the natives still maintained independent governments. The Aztec conquest of the central region, between the Gulf of Mexico and the Pacific, was completed only a few years previous to the arrival of the Spaniards, and the conquest of this region had not been fully secured at some points, as appeared in the readiness of the Tlascalans and others to act in alliance with Cortez. But the Aztecs did not come from abroad. They belonged in the country, and seem to have been originally an obscure and somewhat rude branch of the native race.
