Ancient Civilizations of Mexico and Central America

Plate XXXV

It is difficult to place time limits for the artistic styles that once existed in this northwestern region. The archaic culture seems to have lasted longer here than farther south; next followed the northern flow of Toltecan culture which later receded and finally came a rather thin layer of Chichimecan or Aztecan culture. We may tentatively conclude that the forgotten cities of the Zacatecan subculture flourished after 1000 A. D. The question should be settled because of its connection with the dating of Pueblo ruins farther north.
