Philip Ball investigates claims that the burial chamber of China’s first emperor contains rivers of shimmering mercury

The Chinese emperor had done all he could to become immortal, but in vain. His physicians had prepared herbal and alchemical elixirs, but none could stave off his decline. He had sent a minister on a voyage far over the eastern seas in search of a mythical potion of eternal life. But that expedition never returned, and now the quest seemed hopeless. So Qin Shi Huangdi, the First Emperor of a unified China in the third century BC, had begun preparations for the next best thing to an endless life on Earth. He would continue his cosmic rule from the spirit world, and his underground tomb would be a palace for the afterlife, complete with its own army of life-size clay soldiers.
