The 2,000 Year-Old Mummified Body of Lady Xin Zhui HD – Archaeology Documentary
Mummies from various dynasties throughout China’s history have been discovered in several locations across the country. They are almost exclusively considered to be unintentional mummifications. Many areas in which mummies have been uncovered are difficult for preservation, due to their warm, moist climates. This makes the recovery of mummies a challenge, as exposure to the outside world can cause the bodies to decay in a matter of hours.
An example of a Chinese mummy that was preserved despite being buried in an environment not conducive to mummification is Xin Zhui. Also known as Lady Dai, she was discovered in the early 1970s at the Mawangdui archaeological site in Changsha. She was the wife of the marquis of Dai during the Han dynasty, who was also buried with her alongside another young man often considered to be a very close relative. However, Xin Zhui’s body was the only one of the three to be mummified. Her corpse was so well-preserved that surgeons from the Hunan Provincial Medical Institute were able to perform an autopsy. The exact reason why her body was so completely preserved has yet to be determined.
From daily The Independent in Britain:
Ancient Chinese tomb dating back 2,500 years uncovered to shed light on obscure kingdom
The little-known Luhun kingdom existed between 638BC to 525BC
6 December 2015
Chinese archaeologists have uncovered a 2,500-year-old- tomb thought to contain the skeletons of an ancient royal family.
The tomb in Luoyang city, Henan province, is believed to originate from the relatively-unknown Luhun Kingdom, which only lasted 113 years between 638BC and 525BC, according [to] People’s Daily Online.
Thought to be the tomb of a Luhun nobleman or royal – copper belts and ceremonial pots were discovered along with a nearby burial pit complete with chariots and whole horse skeletons.
The excavation began in 2009 after a spate of grave robbing in the area, which hosts around 200 different ancient tombs, <a href=”http://www.scmp.com/lifestyle/article/1885832/chinas-ancient-treasures-under-siege-army-tomb-raiders” target=”_blank”>South China Morning Post reports.
Due to the tomb’s size, which is at 21 feet long, 17 feet wide and 28 feet deep, experts believe it to be the resting place of a royal family who wielded little political power.
The tomb had suffered from damage caused by water and grave robbers, but the interior coffin was protected by plaster and a coffin board.
The horse burial pit contained the skeletons of 13 horses and six chariots. The horses had been carefully arranged on their sides, with decorations placed on their carcasses.
It is hoped the tomb will help historians gain a better understanding of the movements of the migratory Rong people, an ethnic minority which made up the population of the short-lived Luhan kingdom.
