Kris Hirst Updated April 20, 2019 One of the great treasures of the world is the Terracotta Army of Qin Shi-Huangdi, in which an estimated 8,000 life-sized sculptures of soldiers were placed in rows as part of the Qin ruler's tomb. Constructed between 246 and 209 B.C., the mausoleum complex is much more than just the soldiers and has lent itself to many scientific discoveries. The statues of the infantry soldiers range in size between 1.7 m (5 ft 8 in) and 1.9 m (6 ft 2 in). The commanders are all 2 m (6.5 ft) tall. The lower halves of the kiln-fired ceramic bodies were made of solid terracotta clay, the upper halves were hollow. The pieces were created in molds and then glued together with clay paste. They were fired in one piece. Neutron activation analysis indicates that the sculptures were made from multiple kilns scattered around the countryside, although no kilns have been found to date. Building and Painting a Terracotta Soldier Some hints of three distinct colors are on the face and clothing of this terracotta warrior on display in the Shaanxi History Museum, Xian, China. Tim Graham/Contributor/Getty Images After firing, the sculptures were coated with two thin layers of the poisonous east Asian lacquer (qi in Chinese, urushi in Japanese). On top of the glossy, dark brown surface of the urushi, the sculptures were painted with bright colors laid down thickly. Thick paint was used to imitate bird feathers or ornaments on a silk border. The paint colors chosen involve blends with Chinese purple, cinnabar, and azurite. The binding medium was egg white tempera. The paint, plainly visible to the excavators when the soldiers were first exposed, has mostly flaked and eroded away. Bronze Weaponry TORLEY/Flickr/CC BY 2.0 The soldiers were armed with numerous, fully-functional bronze weapons. At least 40,000 arrowheads and several hundred other bronze weapons have been found to date, likely hafted in wood or bamboo shafts. The metal parts which survive include crossbow triggers, sword blades, lance tips, spearheads, hooks, honor weapons (called Su), dagger-ax blades, and halberds. The halberds and lances were inscribed with the regnal date of construction. The halberds were made between 244-240 B.C. and the lances between 232-228 B.C. Other metal objects often had the names of workers, their supervisors, and workshops. Grinding and polishing marks on the bronze weapons indicate that the weapons were ground using a small hard stone rotary wheel or brush. The arrowheads are extremely standardized in shape. They were composed of a triangular pyramid-shaped point. A tang fitted the point into a bamboo or wooden shaft and a feather was attached at the distal end. The arrows were found bundled in groups of 100 units, probably representing a quiver's worth. The points are visually identical, although tangs are one of two lengths. Neutron activation analysis of the metal content shows they were made in batches by different cells of workers functioning in parallel. The process most likely reflects the way weapons were made for those used by flesh-and-blood armies. The Lost Art of Shi Huangdi's Pottery Kilns Yaohua2000/Wikimedia Commons/CC BY 3.0 Building 8,000 life-sized pottery gentlemen, not to mention the animals and other terracotta sculptures found in the Qin's tomb, must have been a formidable task. Yet, no kilns have been found in association with the emperor's tomb. Several pieces of information suggest that the manufacturing took place by workmen in many locations. The names of workshops on some of the bronze objects, the different metal content of the arrow groups, different types of soils used for the pottery, and pollen shows evidence that work was carried out in several locations. Pollen granules were found in low-fired sherds from Pit 2. Pollen from the horse statues matched that of the near vicinity of the site, including pinus (pine), Mallotus (spurge), and Moraceae (mulberry). Pollen from the warriors, however, were mostly herbaceous, including Brassicaceae (mustard or cabbage), Artemisia (wormwood or sagebrush), and Chenopodiaceae (goosefoot). Researchers postulate that horses with their thin legs were more prone to breakage while being hauled long distances, and so were built in kilns closer to the tomb. Are They Portraits of Individuals? foursummers/Pixabay The soldiers have an amazing amount of variations in headgear, hairdos, costumes, armor, belts, belt hooks, boots, and shoes. There is variation especially in facial hair and expression. Art historian Ladislav Kesner, quoting Chinese scholars, argues that despite the specific traits and seemingly endless diversity of the faces, the figures are better viewed not as individuals but as "types," with the goal being to produce the appearance of individuality. The physicality of the statues is frozen, and the postures and gestures are representations of the clay soldier's rank and role. Kesner points out that the art challenges those in the Western world who conceptually see individuality and type as separate things: the Qin soldiers are both individual and particularized types. He translates the Chinese scholar Wu Hung, who said that the goal of reproducing portrait sculpture would be alien to Bronze Age ritual art, which "aimed to visualize an intermediate stage between the human world and beyond it." The Qin sculptures are a break with the Bronze Age styles, but echoes of the era are still seen in the cool, distant expressions on the soldiers' faces. Sources Bonaduce, Ilaria.
