Image 2 is a historical rendering of a tzompantli or skull rack. It is a type of wooden rack or palisade documented in several Mesoamerican civilizations, which was used for the public display of human skulls, typically those of war captives or other sacrificial victims. In 2017 archeologists announced the discovery of the Huey Tzompantli, with more than 650 skulls, in the archeological zone of the Templo Mayor in Mexico City.
