Xin Zhui (Chinese: 辛追; [ɕín ʈʂwéɪ]; c. 217 BC–169 or 168 BC), also known as Lady Dai or the Marquise of Dai, was a Chinese noblewoman. She was the wife of Li Cang (利蒼), the Marquis of Dai, and Chancellor of the Changsha Kingdom, during the Western Han dynasty of ancient China. Her tomb, containing her well-preserved remains and 1,400 artifacts, was discovered in 1971 at Mawangdui, Changsha, Hunan, China. Her body and belongings are currently under the care of the Hunan Museum; artifacts from her tomb were displayed in Santa Barbara and New York City in 2009. Her body is notable as being one of the most well preserved mummies ever found. Xin Zhui is thought to have lived a wealthy lifestyle. She had private musicians for entertainment who would play for her parties as well as for her personal amusement. She may have enjoyed playing music as well, particularly the guqin, which was traditionally associated with refinement and intellect. As a noble, Xin Zhui also 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 many cosmetics. As she aged, Xin Zhui suffered from many ailments that eventually led to a heart attack that caused her death. Along with schistosomiasis, a parasitic infection, she also had coronary thrombosis and arteriosclerosis, most likely linked to excessive weight gained due to a sedentary lifestyle, diabetes, angina pectoris, liver disease, and hypertension. Lumbago and a compressed spinal disc probably caused her immense pain, which contributed to a decrease in physical activity. She also suffered from gallstones, one of which lodged in her bile duct and further deteriorated her condition. Her arteries were found to be heavily congested, leading to congestive heart failure. A total of 130 melon seeds were found in Xin Zhui’s stomach, intestines, and esophagus; researchers believed she consumed the melon very quickly. From this, researchers inferred that she died in summer, when fruits and melons ripen. The presence of melon seeds in her stomach also indicates that she died within two to three hours of eating the fruit. Xin Zhui died at approximately 50 years of age in 169 or 168 BC. In 1968, workers digging an air raid shelter for a hospital near Changsha unearthed the tomb of Xin Zhui, 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. Xin Zhui’s body was found within four rectangular pine constructs that sat inside one another which were buried beneath layers of charcoal and white clay. The corpse was wrapped in twenty layers of clothing bound with silk ribbons. In the tomb of Xin Zhui, four coffins of decreasing sizes enclose one another. The first and outermost coffin is painted black, the color of death and the underworld. All painted images sealed inside this coffin were thus designed not for an outside viewer but for the deceased and concern the themes of death and rebirth, protection in the afterlife, and immortality. The second coffin has a black background but is painted with a pattern of stylized clouds and with protective deities and auspicious animals roaming an empty universe. A tiny figure, the deceased woman, is emerging at the bottom center of the head end. Only her upper body is shown, indicating she is about to enter a new world. The third coffin exhibits a different color scheme and iconography. It is shining red, the color of immortality, and the decorative motifs include divine animals and a winged immortal flanking three-peaked Mount Kunlun, which is a prime symbol of eternal happiness. Inside this tomb on top of the fourth and innermost coffin, the excavators found a painted silk banner about two meters long. Yellow and black feathers are stuck on the cover board of the coffin. The feathers stuck to the coffin were expressing the hopes that Xin Zhui would grow feathers on the body and enter the heavens to become immortal. Xin Zhui’s body was remarkably well preserved. Her skin was 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 remained intact. The tympanic membrane of her left ear was also intact, and her finger and toe prints were distinct. This preservation allowed doctors at Hunan Provincial Medical Institute to perform an autopsy on 14 December 1972. Much of what is known about Xin Zhui’s lifestyle was derived from this and other examinations. As a member of the nobility, her body would have been washed with fragrant water and wine, which has antibacterial properties.
