In the northeastern basin of the Valley of Mexico, approximately 45 kilometers from modern Mexico City, lies the ancient city of Teotihuacan.  Named “The City of the Gods” by the Aztecs, Teotihuacan was a Mesoamerican manifestation of the cosmos on earth.  From 1 BCE to AD 650, its inhabitants constructed monumental pyramids, apartment compounds, marketplaces, and craft workshops along a network of axes designed to represent earthly and heavenly realms.  The city thrived on religious dedication and sacrifice, evidenced through art, symbolic text, and a wealth of human skeletal remains.
