Here is something interesting:
Archaelologists in Cuzco were performing recovery work in the Chiñisiri Archaelogical complex when they discovered a mummified body of a child in very good condition in the tombs. It is believed that the child, maybe 5-6 years old, and about 50 inches tall, is pre-Incan, as many of the tombs found in this site pre-date the Incas. They think that the child could be from the Wari culture, which flourished from 500-1000 A.D.
I always find it incredibly amazing that things could keep preserved for so long. It is also pretty amazing that cultures that had no direct contact with each other, could have the same ideas and beliefs about honoring the dead. Interesting that Ancient Egyptians and this Wari culture would both figure out and use mummification. I guess this is more proof that no matter what culture you are from or where you live, there are just some things intrinsic to all humans. Kind of comforting.
