COVER In the Aztec city of Tenochtitlan in the 16th century, the skulls of human sacrificial victims were slipped onto wooden posts and displayed on a monumental rack. Archaeologists at Mexico's National Institute of Anthropology and History discovered the remains of the rack and two accompanying skull towers during recent excavations in downtown Mexico City.
