"Of the Toltecs, the probable predecessors in Mexico of the Aztecs, all written records," said the Antiquary, "have long since perished. They are known to us only through traditionary legends orally handed down by the races that succeeded them. "They are said to have entered the Valley of Anahnac from a northerly direction, coming from a mysterious unknown region, and probably before the close of the seventh century. They appear to have been a far more gentle and refined nation than their immediate successors, the half-savage Aztecs, who, at last, with their semi-civilization, dominated Mexico. By general archæological agreement, the Toltecs were well instructed in agriculture, and many of the most useful mechanic arts. "'They were,' declares Prescott, 'nice workers in metals.' They invented the complex arrangement of time adopted by the Aztecs, who are said to have been largely indebted to them for the beginnings of that incongruous civilization which reached its high-water mark in the reign of the Montezumas. So late as the time of the Spanish Conquest the remains of extensive Toltec buildings were to be found in Mexico. "'The noble ruins of religious and other edifices,' says the same writer, 'still to be seen in Mexico, are referred to this people, whose name, _Toltec_, has passed into a synonym for _Architect_.' "After a period of four centuries--having succumbed to famine, pestilence, and unsuccessful wars--this remarkable people disappeared from the land as silently and mysteriously as they had entered it. It is conjectured that some of them may have spread over the region of Central America and the neighboring isles; and that the majestic ruins of Mitla and Paleque are the work of this vanished race. Tradition affirms that a remnant of Toltecs still lingering in Anahnac 'gave points' to the next inhabitants; and the Tezcucans are thought to have derived their gentle manners and comparatively mild religion from the handful of Toltecs who still remained in the country. A Spanish priest, with that keen relish for the marvellous common to his kind, accounts for this mysterious disappearance by supernatural stories of giants and demons. "According to good authorities, more than a hundred years elapsed between the strange disappearance of the Toltecs from the land of Anahnac and the arrival on its borders of the Aztecs. "After the nomadic fashion of barbarous races, this people did not at once make a permanent settlement, but pitched their tents in various parts of the Mexican valley, enduring many casualties and hardships, and being at one time enslaved by a more powerful tribe, whom their prowess subsequently dominated. "Some of these wanderings and adventures are perpetuated in their oral traditional lore.
