We are further told that just about the time of our Norman Conquest, the Toltecs were driven out from the Mexican plateau by famine and pestilence, and migrated again southward. Only a few families remained, and from them the Aztecs, Chichemecs, and other barbarous tribes by whom the country was re-peopled, derived that knowledge of the arts and sciences upon which their own civilization was founded. It was by this Toltec nation—say the Mexican writers—that the monuments of Xochichalco, Teotihuacán, and Cholula were built. In their architecture the Aztecs did little more than copy the works left by their predecessors; and, to this day, the Mexican Indians call a builder a toltecatl or Toltec.

A theory has been propounded to answer this question, that they settled in Chiapas and Yucatan, and built Palenque, Copan, and Uxmal, and the other cities, the ruins of which lie imbedded in the tropical forest.
