In 1974 , farmers slip up across one of the most important archaeological discoveries of all time in an retiring field in the Shaanxi state of China . While digging , they found shard of a human figure made out of clay . This was just the tip of the iceberg . Archaeological excavation divulge the field was sitting above a number of pits that were jam - compact with chiliad of life - sizeterracotta modelsof soldiers and warfare horse , not to mention acrobats , esteemed officials , and other animals .

It appears that the commission of thisTerracotta Armywas to hold the nearby mausoleum of Qin Shi Huang , the unnerving first emperor of the Qin dynasty who prevail from 221 to 210 BCE .

While large parts of thenecropolissurrounding the mausoleum have been explore , the emperor ’s grave itself has never been opened despite the immense amount of intrigue that surrounds it . Eyes have perhaps not peered inside this grave for over 2,000 years , when the feared emperor moth was sealed within .

A prime grounds behind this disinclination is that archeologist are concerned about how the excavation mightdamage the tomb , losing life-sustaining historical info . Currently , only invasive archaeological proficiency could be used to enter the tomb , run a high risk of causing irreparable damage .

One of the clearest deterrent example of this issue forth from the excavations of the urban center of Troy in the 1870s byHeinrich Schliemann . In his hurriedness and naiveness , his work managed to destroy almost all traces of the very metropolis he ’d ready out to unveil . Archaeologists are sure they do n’t want to be impatient and make these same mistakes again .

Scientists havefloated the ideaof using certain non - invasive technique to look inside the tomb . One idea is to utilise negative muon , the subatomic product of cosmic re collide with atoms in the Earth ’s atmosphere , whichcan peer through structureslike an advanced ten - irradiation . However , it looks like most of these proposals have been slow to get off the earth .

Cracking get to the tomb could come with much more straightaway and virulent dangers too . In anaccountwritten by ancient Taiwanese historian Sima Qian around 100 twelvemonth after Qin Shi Huang ’s death , he explains that the tomb ishooked up to booby trapsthat were designed to drink down any intruder .

“ Palaces and scenic tower for a hundred officials were constructed , and the tomb was fill up with rare artifacts and wonderful treasure . Craftsmen were ordered to make crossbows and arrows undercoat to shoot at anyone who enters the grave . Mercury was used to simulate the hundred river , the Yangtze and Yellow River , and the great ocean , and set to flow mechanically , ” it reads .

Even if the 2,000 - year - old bow weapons give out , this business relationship suggests a flood of toxic liquidmercurycould wash across the gravedigger . That might sound like an empty threat , but scientific studies have await at mercury engrossment around the tomb and found significantly higher levels than they ’d look in a typical opus of state .

“ extremely volatile mercury may be lam through crack , which germinate in the structure over time , and our investigation fend for ancient story records on the grave , which is believed never to have been opened / looted , ” the authors of one2020 paperconclude .

For the time being , the grave of Qin Shi Huang remain seal and unobserved , but not forgotten . When the metre is correct , however , it ’s possible that scientific advancements could finally delve into the secrets that have been lie here undisturbed for some 2,200 years .
