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 in his mausoleum with the purpose of protecting him in his afterlife.
The figures, dating from approximately the late 200s BCE, were discovered in 1974 by local farmers in Lintong County, outside Xi'an, Shaanxi, China. The figures vary in height according to their rank, the tallest being the generals. The figures include warriors, chariots and horses. Estimates from 2007 were that the three pits containing the Terracotta Army hold more than 8,000 soldiers, 130 chariots with 520 horses, and 150 cavalry horses, the majority of which remain in situ. Other, non-military terracotta figures have since been found in other pits, including those of officials, acrobats, strongmen, and musicians.
The construction of the tomb was described by the historian Sima Qian (145–90 BCE) in the Records of the Grand Historian, the first of China's 24 dynastic histories, which was written a century after the mausoleum's completion. Work on the mausoleum began in 246 BCE, soon after Emperor Qin (then aged 13) succeeded his father as King of Qin, and Sima said that the project eventually involved 700,000 conscripted workers. Geographer Li Daoyuan, writing six centuries after the first emperor's death, recorded in Shui Jing Zhu that Mount Li was a favoured location due to its auspicious geology: "famed for its jade mines, its northern side was rich in gold, and its southern side rich in beautiful jade; the first emperor, covetous of its fine reputation, therefore chose to be buried there".
Sima Qian wrote that the first emperor was buried with palaces, towers, officials, valuable artifacts and wondrous objects. According to this famous account, 100 flowing rivers were simulated using mercury, and above them the ceiling was decorated with heavenly bodies, below which lay the features of the lands of China which the emperor had unified. Some translations of this passage refer to "models" or "imitations"; however, those words were not used in the original text, which also makes no mention of the terracotta army. Although these elements of Sima Qian's account on the structure of the mausoleum have been seen as credulous in pre-modern assessments, the detection of high levels of mercury that were found in the soil of the tomb mound following the discovery of the mausoleum site have since given credence to Sima Qian's account. Additionally, the Emperor is well documented for building monumental statues in human form during his reign, such as the Twelve Metal Colossi, which were a series of contemporaneous statues that are now lost but have been noted in historical records.
Later historical accounts have suggested that the mausoleum complex and tomb itself had been looted by Xiang Yu, a contender for the throne after the death of the first emperor. However, there are indications that the tomb itself may not have been plundered.
The Terracotta Army was discovered on 29 March 1974 by a group of farmers—Yang Zhifa, his five brothers, and neighbour Wang Puzhi—who were digging a well approximately 1.5 km (0.93 mi) east of the Qin Emperor's tomb mound at Mount Li (Lishan), a region riddled with underground springs and watercourses. For centuries, occasional reports surfaced of pieces of terracotta figures and fragments of the Qin necropolis – roofing tiles, bricks and chunks of masonry. This discovery prompted Chinese archaeologists, including Zhao Kangmin, to investigate, revealing the largest pottery figurine group ever found. A museum complex has since been constructed over the area, the largest pit being enclosed by a roofed structure.
The Terracotta Army is part of a much larger necropolis. Ground-penetrating radar and core sampling have measured the area to be approximately 98 square kilometres (38 sq mi).
The necropolis was constructed as a microcosm of the emperor's imperial palace or compound, and covers a large area around the tomb mound of the first emperor. The earthen tomb mound is located at the foot of Mount Li and built in a pyramidal shape, and is surrounded by two solidly built rammed earth walls with gateway entrances. The necropolis consists of several offices, halls, stables, other structures as well as an imperial park placed around the tomb mound.
The warriors stand guard to the east of the tomb. Up to 5 metres (16 ft) of reddish, sandy soil had accumulated over the site in the two millennia following its construction, but archaeologists found evidence of earlier disturbances at the site. During the excavations near the Mount Li burial mound, archaeologists found several graves dating from the 18th and 19th centuries, where diggers had apparently struck terracotta fragments. These were discarded as worthless and used along with soil to backfill the excavations.
The tomb appears to be a hermetically sealed space approximately 100 by 75 metres (328 ft × 246 ft). The tomb remains unopened, possibly due to concerns over preservation of its artifacts. For example, after the excavation of the Terracotta Army, the painted surface present on some terracotta figures began to flake and fade. The lacquer covering the paint can curl in fifteen seconds once exposed to Xi'an's dry air and can flake off in just four minutes.
Four main pits approximately 7 m (23 ft) deep have since been uncovered in the site excavations. These are located approximately 1,500 m (4,900 ft) east of the burial mound. The soldiers within were laid out as if to protect the tomb from the east, where the Qin Emperor's conquered states lay, and were discovered 7 m below the excavation level.
Pit 1, which is 230 m (750 ft) long and 62 m (203 ft) wide, contains the main army of more than 3,000 figures. It is the largest of the four pits and has eleven parallel corridors, most more than 3 m (10 ft) wide and paved with small bricks with a wooden ceiling supported by large beams and posts. This design was also used for the tombs of nobles and would have resembled palace hallways when built. The wooden ceilings were covered with reed mats and layers of clay for waterproofing, and then mounded with more soil raising them about 2 to 3 m (6 ft 7 in to 9 ft 10 in) above the surrounding ground level when completed.
Pit 2 has cavalry and infantry units as well as war chariots and is thought to represent a military guard. Pit 3 is the command post, with high-ranking officers and a war chariot. Pit 4 is empty, perhaps left unfinished by its builders.
Some of the figures in Pits 1 and 2 show fire damage, while the remains of burnt ceiling rafters have also been found. These, together with the missing weapons, have been taken as evidence of the reported looting by Xiang Yu and the subsequent burning of the site, which is thought to have caused the roof to collapse and crush the army figures below. The terracotta figures currently on display have been restored from the fragments.
Other pits that formed the necropolis have also been excavated. These pits lie within and outside the walls surrounding the tomb mound. They variously contain bronze carriages, terracotta figures of entertainers such as acrobats and strongmen, officials, stone armour suits, burial sites of horses, rare animals and labourers, as well as bronze cranes and ducks set in an underground park.
The terracotta figures are life-sized, typically ranging from 1.75 metres (5 ft 9 in) to about 2 metres (6 ft 7 in) (the officers are typically taller). They vary in height, uniform, and hairstyle in accordance with their portrayed rank. Their faces appear to be different for each individual figure. Scholars have identified 10 base facial forms which were then further developed to give each figure individuality in terms of facial morphology. The figures are of these general types: armored infantry; unarmored infantry; cavalrymen who wear a pillbox hat; helmeted drivers of chariots with more armor protection; spear-carrying charioteers; kneeling crossbowmen or archers who are armored; standing archers who are not; as well as generals and other lower-ranking officers. There are, however, many variations in the uniforms within the ranks: for example, some may wear shin pads while others not; they may wear either long or short trousers, some of which may be padded; and their body armors vary depending on rank, function, and position in formation. There are also terracotta horses placed among the warrior figures.
