With the development of modern archaeology, many ancient tombs have been excavated in Our country, and many precious cultural relics have been found, filling the gaps in historical documents.In addition to these grave goods, the owner of the tomb is also our focus, most of these body discovered under the years erosion deformed, but in the anti-corrosion technology in place, or grave under the environment of power, there are some one thousand body discovered preserved better, such as in hunan changsha mawangdui unearthed in 1972, has caused great sensation.In fact, there is a millennium and Mawangdui female corpse with the same name – Wumeng Qidan female corpse, this female corpse belongs to the north mummified, these two well-preserved ancient corpse again verified that the truth “dry for a thousand years, wet for ten thousand years, not wet for half a year.”The body was found in 1981 in Ulanqab League, Inner Mongolia, and the woman was a Khitan.A heavy rain found her with blood under her body and poison in her stomach.In the early morning of 1981, after several days of rain, it finally stopped. An old shepherd in The Hao Qian Camp of Wulanchabu League in Inner Mongolia Autonomous Region drove his sheep to graze on the mountain. The sheep walked slowly on the slippery road until they finally stopped.Why didn’t the sheep want to go?The old shepherd went to the sheep and saw a dark cave in front of the sheep, blocking the way.The old shepherd walked this road every day, but he had never seen this hole. There were some broken gray bricks and tiles beside the hole, which were clearly dug by hand.Think of this layer, the old shepherd also do not herd sheep, hurriedly ran down the mountain to the village cadres to report this matter, a lot of people may not understand, feel the old shepherd fuss.This has to say that the old shepherd walked on the mountain, mountain named Wanzi Mountain, there are groups of cemeteries on the mountain, this is because the wanzi mountain cemetery this piece of terrain is special, with rolling hills, the cemetery back to the mountains, facing the valley, there are two prototype hills in the southeast.Such terrain was a good place for the Khitan, so the mountain cemetery was a popular destination for tomb raiders.The old shepherd, therefore, was always ready when he saw the opening, for it was likely to be a hole dug by tomb robbers, and in case the tomb was destroyed, an opportunity for study would be lost.Village cadres listen to him finish this is also very important, he knows that this is important, so quickly contacted the local cultural relics workstation of Wulanchabu League, cultural relics workstation heard the situation there, quickly organized archaeological experts to mount Bay for investigation, determine the situation.After a long and well-armed job, the team arrived at their conclusion that a dozen tombs had been found near the stolen cave, apparently a large family grave.Through the identification of tomb materials, it was finally learned that this ancient tomb group was roughly built in the 10th century, and according to the judgment of the characteristics of the tomb, confirmed that this group of tombs belonged to the Khitan mobei ethnic group.Khitan is a mysterious people, which had glorious days in history, but eventually disappeared silently. This tomb group of Khitan is likely to reveal to us the lost history of the Khitan. Considering the discovery of stolen caves, we decided to organize rescue excavation, and excavated three tombs first.Although they were prepared, the first two tombs were dug up by thieves, leaving the experts with a chill.The third tomb dug by the Khitan women was the one near the stolen cave. This tomb was the one we least expected, but it gave us the biggest surprise.The tomb was well preserved after the thieves failed to get into it despite a hole in the ground.In addition to an array of artifacts inside the tomb, the occupant of the tomb on the bed was also a surprise. The well-preserved corpse, apparently female in appearance, even had elastic muscle tissue.Her body was well preserved, but the clothes on her body had been eroded to pieces. Only from the remnants of the body could we tell that the woman was wearing multiple layers of funeral clothes. The first was three layers of robes, namely embroidered silk robe, purple silk robe, medium yellow silk robe, and inside the robe was a short dress and a silk skirt.The female body also wore a layer of copper mesh clothing, which, like the “Jade clothing” of central Plains, was believed by ancient people to have the function of protecting the body.Archeologists attached great importance to this female corpse, Inner Mongolia quickly reported to the Chinese Academy of Social Sciences archaeological Institute at that time.The woman’s body was carefully removed from the tomb after heavy rain, and an analysis of her teeth in her mouth determined that the woman’s body was about 25 years old.This female corpse has not been corrupt for thousands of years, and is buried with rich goods, including copper mesh clothes and gilt copper mask, experts confirmed that this female corpse should be a Khitan nobleman.The cause of death into a mystery when the female corpse unearthed face lifelike, seems to be just asleep, preserved almost as well as ma Wangdui unearthed Xin Chase lady.However, after confirming her age, we encountered a question: the ancient people had a short life span, but there was no reason for them to die at the age of 25. The Khitan female corpse obviously died abnormally, so what was the cause of her death?The corpse of the woman looks good, but the internal organs are rotting away, and through the study of the remaining organs and tissues, we have a surprising discovery, in the stomach of the corpse of the woman found a large amount of arsenic, also known as the folk highly toxic arsenic, in her stomach fully found 100 grams of arsenic, this amount is enough to kill.So the female body was poisoned by arsenic, further research overturned this speculation, the original identification of the female body abdominal tissue did not detect arsenic, then there is only one possibility, the female body was already dead when eating arsenic, the organization lost activity, so the stomach arsenic did not penetrate diffusion.At that time, people used to embalm arsenic, so the woman’s body must have been injected with arsenic during embalming.Another special feature of the Khidan female corpse is that there is a piece of cloth called “thang cloth” between the two strands. This cloth is well preserved, still has the elasticity of a textile, and there is blood stains on it, which is preliminarily judged to have come from the female corpse.Therefore, another theory emerged that the Khitan women probably died of bleeding caused by obstructed labor, after all, childbirth in modern times is also accompanied by many risks, let alone ancient times.Summary: We have not been able to get solid evidence of the cause of death of the female corpse, the reason why the body did not decay for thousands of years is also a mystery, only a few speculations: for example, arsenic does have an anticorrosive effect, and there is a lot of arsenic in the body of the female body, and the copper rust on the copper mesh clothing also has some anticorrosive effect.Modern science has developed so far, with more and more tools, that we may one day discover secrets that history has hidden.
