What was discovered

Systematic research on Nahua society using questionnaires, informants from different towns and a Nahuatl text with images, recorded in the General History of the Things of New Spain. It is regarded as a forerunner of modern ethnography.

Calling Sahagún 'the first ethnographer' is a historiographical judgement (Klor de Alva, León-Portilla), not a fact; the work developed between Tepepulco, Tlatelolco and Mexico City and the final manuscript (Florentine Codex) dates to c. 1577.

What it led to

  • The main source on Mexica culture, religion and medicine
  • A model of fieldwork with informants and cross-checking
  • Preservation of written Classical Nahuatl
