One glimpse of the corpses was enough to shock Victor Mair profoundly. In 1987, Mair, a professor of Chinese at the University of Pennsylvania, was leading a tour group through a museum in the Chinese city of Ürümqi, in the central Asian province of Xinjiang, when he accidentally strayed into a gloomy, newly opened room. There, under glass, lay the recently discovered corpses of a family--a man, a woman, and a child of two or three--each clad in long, dark purple woolen garments and felt boots. "Even today I get chills thinking about that first encounter," says Mair. "The Chinese said they were 3,000 years old, yet the bodies looked as if they were buried yesterday."
But the real shock came when Mair looked closely at their faces. In contrast to most central Asian peoples, these corpses had obvious Caucasian, or European, features--blond hair, long noses, deep-set eyes, and long skulls. "I was thunderstruck," Mair recalls. "Even though I was supposed to be leading a tour group, I just couldn't leave that room. The questions kept nagging at me: Who were these people? How did they get out here at such an early date?"
The corpses Mair saw that day were just a few of more than 100 dug up by Chinese archeologists over the past 16 years. All of them are astonishingly well preserved. They come from four major burial sites scattered between the arid foothills of the Tian Shan ("Celestial Mountains") in northwest China and the fringes of the Taklimakan Desert, some 150 miles due south. All together, these bodies, dating from about 2000 B.C. to 300 B.C., constitute a significant addition to the world's catalog of prehistoric mummies. Unlike the roughly contemporaneous mummies of ancient Egypt, the Xinjiang mummies were not rulers or nobles; they were not interred in pyramids or other such monuments, nor were they subjected to deliberate mummification procedures. They were preserved merely by being buried in the parched, stony desert, where daytime temperatures often soar over 100 degrees. In the heat the bodies were quickly dried, with facial hair, skin, and other tissues remaining largely intact.
