The Terracotta Army is a collection of terracotta sculptures depicting the armies of Qin Shi Huang, the first Emperor of China. It is a form of funerary art buried with the emperor in 210–209 BCE and whose purpose was to protect the emperor in his afterlife. The figures, dating from approximately the late third century BCE, were discovered in 1974 by local farmers digging a water in Shaanxi province. The figures vary in height according to their roles, with the tallest being the generals. The figures include warriors, chariots and horses. There are estimates that the three pits containing the Terracotta Army held more than 8000 soldiers, 130 chariots with 520 horses and 150 cavalry horses. The Terracotta Army is part of a much larger necropolis covering the area of approximately 98 square kilometers.
