Aztec Temple of Blood

I caught the end of a repeat broadcast of the Aztec Temple episode from the Unsolved History series cable's Military Channel last night. It originally aired on TLC or Discovery a few years ago.

In 1519, the Aztecs were the most powerful and fearsome civilization in the Americas. The center of Aztec life was Templo Mayor, located in the middle of their capital city, Tenochtitlan, now modern Mexico City. The 12-story pyramid was used for worship.

The blurb above doesn't begin to do the show justice as it features not only recreations of Aztec and Spanish weapons, their use and a comparison of effects, but human sacrifice experimental archaeology!
