Pablo of Texcoco was an Indigenous descendant of the Aztecs who lived in the central valley of Mexico in the second half of the sixteenth century. He was trained in the Nahua or Aztec art of rhetoric in the powerful city-state of Texcoco, which has been called the "Athens" of preconquest Mesoamerica because of its beautiful architecture and gardens and because of its people's reputation for a love of poetic songs. Frances Karttunen retired as Senior University Research Scientist at the Linguistics Research Center at the University of Texas at Austin, where she established the Early Mesoamerican Languages Project. Her books include The Art of Nahuatl Speech: The Bancroft Dialogues. Camilla Townsend is the Board of Governors Distinguished Professor of History at Rutgers University. Her books include the Cundhill History Prize-winning Fifth Sun: A New History of the Aztecs.
