Quick questions on Han art, technology and culture: HSC Ancient History

Lacquerware. Mawangdui Tomb 1, near Changsha in Hunan, the burial of Lady Dai (Xin Zhui), sealed around 168 BC, is the outstanding evidence for Han lacquer art: finely painted lacquer cups, boxes and trays survived in exceptional condition, some marked with a workshop name and quality grade, alongside a silk gauze robe weighing only about 49 grams and the celebrated T-shaped painted silk funerary banner, which depicts a three-tiered cosmological journey of the soul through the underworld, the earthly realm and the heavens. Historian Anthony Barbieri-Low has used inscribed marks on surviving lacquerware to reconstruct an organised, tracked Han manufacturing system, with named private and state workshops competing on quality.

The Hou Hanshu (History of the Later Han) credits Cai Lun, an official attached to the imperial workshops, with presenting an improved papermaking process to Emperor He in AD 105, made from mulberry bark, hemp waste, old rags and fishing nets. Archaeological finds of paper fragments at sites such as Fangmatan, in Gansu, in a Western Han context, appear to predate Cai Lun by roughly two centuries, so most historians of Chinese science, including Tsien Tsuen-Hsuin, read Cai Lun's contribution as standardising and improving an existing crude process into a cheap, durable, mass-producible material, rather than inventing paper outright.

Zhang Heng (AD 78 to 139), an Eastern Han astronomer, mathematician and court official, built the houfeng didong yi (earthquake weathervane) in AD 132: a bronze vessel ringed by eight dragon heads, each holding a small ball, with eight bronze toads positioned below, one per dragon, corresponding to eight compass directions. A tremor was intended to trigger an internal mechanism (traditionally described as a swinging pillar) that released the ball from the dragon facing the direction of the shock, which fell into the toad's mouth below with an audible sound, registering both the fact and the rough direction of a distant earthquake.

Han armouries mass-produced a standardised bronze trigger mechanism with interchangeable cast parts, giving Han crossbows a reliable, precise release compared with earlier or contemporary designs elsewhere. Combined with state arsenals and conscript training, this gave Han infantry a real technological edge on the northern frontier against Xiongnu cavalry.

The earliest known depiction of a wheelbarrow is a brick tomb relief from Sichuan, usually dated to around AD 118, showing a single-wheeled cart being pushed by one person. A single central wheel let one labourer shift a load that had previously needed two people carrying a pole-slung basket, a real efficiency gain for farm transport, construction and military supply.

Du Shi, Prefect of Nanyang, is credited with inventing a water-powered reciprocating bellows around AD 31, mechanising the blast of air into iron-smelting furnaces so that flowing water, rather than manual labour, drove higher furnace temperatures and greater output. This fed directly into the state salt and iron monopoly established under Emperor Wu (from about 119 BC), which financed frontier warfare and distributed cast-iron tools, including ploughshares, to Han farmers. Han furnaces of this period could reach the temperatures needed for cast iron, a capability Western blast-furnace technology would not match for well over a thousand years.

Zhang Heng also built a water-powered armillary sphere (hun tian yi), using a water clock (clepsydra) to rotate the instrument in time with the apparent motion of the heavens, an early example of mechanised astronomical observation. His treatise the Ling Xian (Treatise on the Mystical Constitution of the Universe) described a spherical model of the cosmos and gave a value for pi of approximately 3.162 (the square root of 10), a rough but genuine mathematical estimate later refined by mathematicians such as Liu Hui.

Mawangdui Tomb 1, near Changsha in Hunan, the burial of Lady Dai (Xin Zhui), sealed around 168 BC, is the outstanding evidence for Han lacquer art: finely painted lacquer cups, boxes and trays survived in exceptional condition, some marked with a workshop name and quality grade, alongside a silk gauze robe weighing only about 49 grams and the celebrated T-shaped painted silk funerary banner, which depicts a three-tiered cosmological journey of the soul through the underworld, the earthly realm and the heavens.

The "Flying Horse of Gansu", excavated in 1969 from an Eastern Han tomb at Leitai, near Wuwei in Gansu, and dated to the 2nd century AD, depicts a galloping horse balanced with a single hoof on a flying swallow. The technical achievement, casting a large bronze figure balanced convincingly on one small point of contact while conveying full-stride motion, has made it one of the most reproduced images of ancient Chinese art, later adopted as the emblem of China's national tourism administration.

Liu Sheng, a Han prince who died in 113 BC, and his wife Dou Wan were buried at Mancheng in Hebei, in tombs excavated in 1968, each in a suit of thousands of small rectangular jade plaques sewn together with gold thread, commonly cited as roughly 2,498 plaques for Liu Sheng and around 2,160 for Dou Wan. Han elites believed jade's incorruptibility could preserve the body and protect the spirit after death; later Han ritual texts describe grading suit thread by rank (gold, silver, then lesser materials for lower nobility). Excavation found only skeletal remains inside both suits, a reminder that the ritual belief did not match the physical outcome.

Stone and brick tomb reliefs (huaxiangshi), well documented from sites in Shandong and Sichuan and studied extensively by the art historian Wu Hung, depict banquets, agricultural labour, myth, and moral exemplar stories, giving a rare visual record of a wider social world than lacquer, bronze or jade alone. Painted silk banners, of which the Mawangdui example is the finest surviving case, are far rarer than stone or bronze art because silk perishes easily, making Mawangdui's preservation (in a deep, sealed, clay-packed tomb) exceptional rather than typical.

The fu, often translated "rhapsody", is an elaborate, catalogue-like form combining ornate descriptive prose and verse, frequently composed for the imperial court. Sima Xiangru (179 to 117 BC) is the most celebrated Han fu writer, closely associated with Emperor Wu's court; his paired rhapsodies, the Zixu fu (Rhapsody of Sir Fantasy) and the Shanglin fu (Rhapsody on the Shanglin Park), extol the scale and splendour of the emperor's hunting park in language designed to celebrate, and implicitly flatter, Han imperial power.

The Confucian Five Classics (the Yijing, Shijing, Shujing, Liji and Chunqiu) anchored elite literacy and, from Emperor Wu's reign, the curriculum of the Imperial Academy. Han scholarship also produced a genuine textual controversy: the "Old Text" versus "New Text" classics dispute, in which scholars debated whether versions of the Classics reconstructed from memory after the Qin book-burning (New Text) or later-discovered, archaically written versions promoted by scholars such as Liu Xin under Wang Mang (Old Text) were authoritative, a real Han-era debate over what counted as reliable evidence for the ancient past.

Sima Qian (c. 145 to 86 BC), the Han court's Grand Historian, wrote the Shiji (Records of the Grand Historian), a history running from legendary antiquity to his own day, organised into annals, chronological tables, treatises and biographies, a structure later dynastic histories imitated. Sima Qian completed the work, by his own account in a letter to Ren An, despite suffering castration around 99 BC as punishment for defending a general who had surrendered to the Xiongnu, choosing to endure the humiliation rather than end his life before finishing it, completing the Shiji by around 91 BC.
