What it is

A wooden club with grooved edges set with obsidian blades, so sharp that according to chroniclers it could decapitate a horse. It was the characteristic shock weapon of Mexica warriors.

Its use is attested from the first millennium AD and Preclassic depictions are cited; the first unambiguous images and their chronology are debated. The detailed description comes from 16th-century chroniclers and almost no original specimens survive (the one in Madrid's Royal Armoury was lost in a fire in 1884).

What it led to

  • Mexica combat tactics against the conquistadors
  • obsidian-edged weapons such as the tepoztopilli
  • ritual and military symbol of power in codices
