Evidence of warriors' protection set in stone

The Terracotta Warriors, the sculptured guards designed to safeguard the first emperor of a unified China in his afterlife, had armor and helmets made of stone for protection.

Archaeologists have found what they believe to be an underground arsenal in Xi'an, the capital of Shaanxi province, at the mausoleum of Qin Shihuang, founding emperor of the Qin Dynasty (221206 BC).

The Emperor Qin Shihuang's Mausoleum Site Museum in the city's Lintong district says archaeologists excavating a burial pit at the cemetery have found many examples of stone armor and helmets.
