Pre-Columbian America [PDF ebook] 

From the Mayan calendar to the Toltec architecture at Chichen Itza, the bequests of ancient Mesoamerican civilizations have endured long after the societies that created them declined. The intellectual and cultural achievements of Pre-Columbian America rivaled those of ancient Rome and Egypt, and greatly enriched the landscape of present-day Mexico and Central America. The traditions, social organizations, languages, and ideas that shaped each of these cultures are examined in this fascinating volume.
