rbatham sends a link to the recent news story on the Huey Tzompantli, a skull rack some 60 metres in diameter which was part of the Templo Mayor complex:
Said to be the heads of defeated warriors, contemporary accounts describe tens of thousands of skulls looming over the soldiers - a reminder of what would happen if they did not conquer territory.
For the next 500 years, the skulls lay undisturbed underneath what was once the Aztec capital Tenochtitlan, but is now Mexico City.
