The figures, dating from 3rd century BC, were discovered in 1974 by some local farmers in Lintong District, Xi'an, Shaanxi province.
The figures vary in height according to their roles, with the tallest being the generals. The figures include warriors, chariots and horses. Current estimates are that in the three pits containing the Terracotta Army there were over 8,000 soldiers, 130 chariots with 520 horses and 150 cavalry horses, the majority of which are still buried in the pits near by Qin Shi Huang's mausoleum.
Other terracotta non-military figures were also found in other pits and they include officials, acrobats, strongmen and musicians.
The terracotta army figures were manufactured in workshops by government laborers and by local craftsmen, and the material used to make the terracotta warriors originated on Mount Li. The head, arms, legs and torsos were created separately and then assembled. Studies show that eight face moulds were most likely used, and then clay was added to provide individual facial features.
Once assembled, intricate features such as facial expressions were added. It is believed that their legs were made in much the same way that terracotta drainage pipes were manufactured at the time. This would make it an assembly line production, with specific parts manufactured and assembled after being fired, as opposed to crafting one solid piece and subsequently firing it. In those times of tight imperial control, each workshop was required to inscribe its name on items produced to ensure quality control. This has aided modern historians in verifying that workshops that once made tiles and other mundane items were commandeered to work on the terracotta army. Upon completion, the terracotta figures were placed in the pits in precise military formation according to rank and duty.
The terracotta figures are life-sized. They vary in height, uniform and hairstyle in accordance with rank. Most originally held real weapons such as spears, swords, or crossbows. The figures were also originally painted with bright pigments, variously coloured in pink, red, green, blue, black, brown, white and lilac.
The coloured lacquer finish, individual facial features, and actual weapons used in producing these figures created a realistic appearance. Most of the original weapons were thought to have been looted shortly after the creation of the army, or have rotted away, and the colour coating has flaked off or greatly faded. However, their existence serves as a testament to the amount of labor and skill involved in their construction.
