Xin Zhui (辛追) was the wife of Li Cang (利蒼), the Marquis of Dai, during the Han dynasty (206 BCE – 220 CE).
As a noble Xin Zhui lived an extravagant lifestyle. She enjoyed having her own musicians for entertainment, had access to a variety of imperial foods, including various types of meat, which were reserved for the royal family and members of the ruling class. Most of her clothing was made of silk and other valuable textiles, and she owned a variety of cosmetics.
This in itself is not that interesting, but what if I told you that she is one of the best preserved mummies of all time.
After outliving her husband and, possibly, her son, Xin Zhui died around 50 years of age in 163 BCE. She was buried in an immense tomb at Mawangdui in Changsha, with more than 1,000 items ranging from drink and food vessels, to silk clothing and tapestries, to figurines of musicians and mourners.
She herself was enclosed within four pine coffins of decreasing sizes, all decorated in the theme of death and rebirth. They were buried beneath layers of charcoal and white clay. With the corpse itself wrapped in twenty layers of clothing bound with silk ribbons.
This tomb was discovered in 1971, by workers digging an air raid shelter, as well as the tombs of her husband and a young man who is most commonly thought to be her son. With the assistance of over 1,500 local high school students, archaeologists began a large excavation of the site beginning in January 1972.
When they discovered her corpse they found Xin Zhui's body was remarkably preserved.
Her skin was still soft and moist, with muscles that still allowed for her arms and legs to flex at the joints. All her organs and blood vessels were also intact, with small amounts of Type A blood being found in her veins. There was hair on her head, with a wig pinned with a hair clasp on the back of her head. There was skin on her face, and her eyelashes and nose hair still exist. The tympanic membrane of her left ear was intact, and her finger and toe prints were distinct.
The cause of this extraordinary preservation is unknown, although it was found that Xin Zhui's body was soaked in an unknown liquid that was mildly acidic with some magnesium in it.
Scientists in 2003 developed a "secret compound" that was injected into Xin Zhui's still existing blood vessels to assure her preservation. Research at the Hunan Provincial Museum continues in an effort to perfect corpse preservation, using Xin Zhui as the main candidate for such procedures.
Despite being 2,190 years dead, she is disturbingly alive.
That’s almost as long as long life milk can last until it spoils!
