Summary

Nahua peoples in central Mexico in the late postclassic period (1200–1521) and the early colonial period (1521–1650) had a sophisticated and complex system of healing known as tiçiyotl. Titiçih, the practitioners of tiçiyotl, were men and women that had specialized knowledge of rocks, plants, minerals, and animals. They used these materials to treat diseases and injuries. Furthermore, titiçih used tlapohualiztli (the interpretation of objects to obtain information from nonhuman forces) to ascertain the source of a person’s ailment. For this purpose, male and female titiçih interpreted cords, water, tossed corn kernels, and they measured body parts. Titiçih could also ingest entheogenic substances (materials that released the divinity within itself) to communicate with nonhuman forces and thus diagnose and prognosticate a patient’s condition. Once a tiçitl obtained the necessary information to understand his or her patient’s affliction, he or she created and provided the necessary pahtli (a concoction used to treat an injury, illness, or condition) for the infirm person. Finally, titiçih performed important ritual offerings before, during, and after healing that insured the compliance of nonhuman forces to restore and maintain their patients’ health.
