Information about History Of Silk

The history of silk begins, according to Chinese tradition, in the 27th century BC. The Chinese were able to continue making it exclusively for three millennia without ever divulging the secret process whereby it was made. The art of silk making slowly spread to other civilizations via merchants, looters, and spies. Having arrived in Europe at the end of the Middle Ages, the production of silk climaxed during the phase of industrialization at the beginning of the 19th century. After that, silk production experienced a rapid decline due to improvements in manufacturing in certain Asian countries and to epidemics that affected the silk worms in France.

Early history

The appearance of silk

The earliest evidence of silk was found at the sites of Yangshao culture in Xia, Shanxi, where a silk cocoon was found cut in half by a sharp knife, dating back to 5,000 to 3,000 BC, the species of which was identited as bombyx mori, the domesticated silkworm. Fragments of primitive loom can also be seen from the sites of Hemudu culture in Yuyao, Zhejiang, dated to about 4,000 BC. Fragments of silk were found in a Liangzhu culture site at Qianshanyang in Huzhou, Zhejiang, dating back to 2,700 BC.^[1][2] Other fragments have been recovered from royal tombs in the Shang Dynasty (ca. 1600 BC - ca. 1046 BC).^[3]

During the later epoch, the Chinese lost their secret as the Koreans, the Japanese, and later the Indians succeeded in discovering how to make silk. Allusions to the fabric in the Old Testament show that it was known in western Asia in biblical times.^[4] Scholars believe that since the 2nd century BC the Chinese established a commercial network aimed at exporting silk to the West.^[4] Silk was used, for example, by the Persian court and its king, Darius III, when Alexander the Great conquered the empire.^[4] Even though silk rapidly spread across Eurasia, its production remained for three millennia exclusively Chinese (with the possible exception of Japan).

Myths and legends

The writings of Confucius and Chinese tradition recount that in the 27th century BC a silk worm's cocoon fell into the tea cup of the empress Leizu.^[5] Wanting to extract it from her drink, the young girl of fourteen began to unroll the thread of the cocoon. She then had the idea to weave it. Having observed the life of the silk worm on the recommendation of her husband, the Yellow Emperor, she began to instruct her entourage the art of raising silk worms, sericulture. From this point on, the girl became the goddess of silk in Chinese mythology. Silk would eventually leave China in the hair of a princess promised to a prince of Khotan. This probably occurred in the early 1st century CE.^[6] The princess, refusing to go without the fabric she loved, would finally break the imperial ban on silk worm exportation.

Though silk was exported to foreign countries in great amounts, sericulture remained a secret that the Chinese guarded carefully. Consequently, other peoples invented wildly varying accounts of the source of the incredible fabric. In classical antiquity most Romans, great admirers of the cloth, were convinced that the Chinese took the fabric from tree leaves.^[7] This belief was affirmed by Seneca the Younger in his Hippolytus and by Virgil in his Georgics. Notably, Pliny the Elder knew better. Speaking of the bombyx or silk moth, he wrote in his Natural Histories "They weave webs, like spiders, that become a luxurious clothing material for women, called silk."^[8]

Silk usage in Ancient and Medieval China

In China, silk worm farming was originally restricted to women, and many women were employed in the silk-making industry. Even though some saw the development of a luxury product as useless, silk provoked such a craze among high society that the rules in the Li Ji were used to regulate and limit its use to the members of the imperial family.^[3] Peasants did not have the right to wear silk until the Qing dynasty (1644-1911).^[3]

For approximately a millennium, the right to wear silk was reserved for the emperor and the highest dignitaries. Later, it gradually extended to other classes of Chinese society. Silk began to be used for decorative means and also in less luxurious ways: musical instruments, fishing, and bow-making.

Paper was certainly one of the greatest discoveries of China. Since the 3rd century BC, paper was made in all sizes with various materials.^[9] Silk workers had been making paper since the 2nd century BC. Silk, bamboo, linen, wheat and rice straw were all used differently, and paper made with silk became the first type of luxury paper. Researchers have found in the tomb of a Marchioness who died around 168, in Mawangdui, Hunan an example of writing done on silk paper. The material was certainly more expensive, but also more practical than bamboo. Treatises on many subjects (meteorology, medicine, astrology, divinity), and even maps written on silk^[10] have been discovered.

During the Han Dynasty, silk became progressively more valuable in its own right, and no longer simply a material. It was used to pay government officials and compensate citizens who were particularly worthy. By the same token that one would sometimes estimate the price of products according to a certain weight of gold, the length of the silk cloth became a monetary standard in China. The wealth that silk brought to China stirred up envy in neighbouring peoples. Beginning in the 2nd century BC the Xiongnu, regularly pillaged the provinces of the Han Chinese for around 255 years. Silk was a common offering by the emperor to these tribes in exchange for peace. For more than one millennium, silk remained the principle diplomatic gift of the emperor of China to his neighbours or to his vassals.^[3] The use of silk became so important that "silk" (纟) soon constituted one of the principal radicals of the Chinese alphabet (230 of the 5000 characters the most frequently used).

Broadly speaking, the use of silk was regulated by a very precise code in China. For example, the Tang Dynasty imposed upon bureaucrats the use of a particular colour according to their different functions in society. Under the Ming, silk began to be used in a series of accessories: hankerchiefs, wallets, belts, or even an embroidered piece of fabric displaying dozens of animals, real or mythical. These fashion accessories remained associated with a particular position: there was a specific bonnet for warriors, for judges, for nobles, and others for religious use. The women of high Chinese society heeded codified practices and used silk in their garments to which they added countless motifs.^[3] A 13th century work, the Jinpingmei, gives a description of one such motif:

Chinese silk and its commerce

A number of discoveries showed that silk was rapidly becoming a luxury material appreciated in foreign countries. Its role in commerce dates well before the opening of the silk road by the Chinese. For example, silk has been found in the Valley of Kings in a tomb of a mummy dating from 1070 BC.^[11]

First the Greeks, then the Romans began to speak of the Seres (people of silk), a term to designate the inhabitants of the far-off kingdom, China. According to certain historians, the first Roman contact with silk was that of the legions of the governor of Syria, Crassus. At the Battle of Carrhae, near to the Euphrates, the legions were so surprised by the brilliance of the banners of Parthia that they fled.^[11]



The silk road toward the west was opened by the Chinese in the 2nd century A.D. The main road left from Beijing, going either to the north or south of the Taklamakan desert, one of the most arid in the world, before crossing the Pamir Mountains. The caravans that employed this method to exchange silk with other merchants were generally quite large, including from 100 to 500 people as well as camels and yaks carrying around 140 kg (300 lb) of merchandise. They linked to Antioch and the coasts of the Mediterranean, about one year's travel from Beijing. In the South, a second route went by Yemen, Burma, and India before rejoining the northern route.^[12] Not long after the conquest of Egypt in 30 BC, regular commerce began between the Romans and Asia, marked by the Roman appetite for silk cloth coming from the Far East, which was then resold to the Romans by the Parthians. The Roman Senate tried in vain to prohibit the wearing of silk, for economic reasons as well as moral ones. The import of Chinese silk resulted in vast amounts of gold leaving Rome, to such an extent that silk clothing was perceived as a sign of decadence and immorality.

	I can see clothes of silk, if materials that do not hide the body, nor even one's decency, can be called clothes.... Wretched flocks of maids labour so that the adulteress may be visible through her thin dress, so that her husband has no more acquaintance than any outsider or foreigner with his wife's body.
—Seneca the Younger, Declamations Vol. I.[13]

Spread of production

Spread to Italy

Although silk was well known in Europe and most of Asia, China was able to keep a near monopoly on silk production. The monopoly was defended by an imperial decree, condemning to death anyone attempting to export silkworms or their eggs. Only around the year 300 AD did a Japanese expedition succeed in taking some silkworm eggs and four young Chinese girls, who were forced to teach their captors the art of sericulture.^[14] Techniques of sericulture were subsequently introduced to Japan on a larger scale by frequent diplomatic exchanges between the 8th century and 9th centuries.

Starting in the 4th century BC, silk began to reach the West by merchants who would exchange it for gold, ivory, horses or precious stones. Up to the frontiers of the Roman Empire, silk became a monetary standard for estimating the value of different products. Hellenistic Greece appreciated the high quality of the Chinese goods and made efforts to plant mulberry trees and breed silkworms in the Mediterranean basin. Sassanid Persia controlled the trade of silk destined for Europe and Byzantium.

It was not until 552 AD that the Byzantine emperor Justinian obtained the first silkworm eggs. He had sent two Nestorian monks to Central Asia, and they were able to smuggle silkworm eggs to him hidden in rods of bamboo. While under the monks' care, the eggs hatched, though they did not cocoon before arrival. The Byzantine church was thus able to make fabrics for the emperor, with the intention of developing a large silk industry in the Eastern Roman Empire, using techniques learnt from the Sassanids. These gynecia had a legal monopoly on the fabric, but the empire continued to import silk from other major urban centres on the Mediterranean.^[15]. The magnificence of the Byzantine techniques was not a result of the manufacturing process, but instead of the meticulous attention paid to the execution and decorations. The weaving techniques they used were taken from Egypt. The first diagrams of semple looms appeared in the 5th century.^[16]

In the same period, the Persians also mastered silk production. The Arabs, having invaded Persia in the 7th century, brought with them both Islam and the secret of sericulture. The Arabs also brought this combination of sericulture and Islam to many places on the shores of the Mediterranean, including Africa, Spain and Sicily, all of which developed a very important silk industry.^[17]

Since the Chinese lost their monopoly on silk production, there was no longer a market for the most basic of their silk products. They did, however, maintain dominance in the luxury silk item market, and China continued to export high-quality fabric to Europe and the Near East along the silk road.

Much later, following the crusades, techniques of silk production began to spread across Western Europe. In 1147, whilst Byzantine emperor Manuel I Komnenos was focusing all his efforts on the Second Crusade, the Norman king Roger II of Sicily attacked Corinth and Thebes, two important centres of Byzantine silk production. They took the crops and silk production infrastructure, and deported all the workers to Palermo, thereby causing the Norman silk industry to flourish.^[18] The sack of Constantinople by the Fourth Crusade in 1204 brought decline to the city and its silk industry,^[17] and many artisans left the city in the early thirteenth century. Italy developed a large domestic silk industry, after 2000 skilled weavers came from Constantinople. Many also chose to settle in Avignon to furnish the popes of Avignon.

The sudden boom of the silk industry in the Italian state of Lucca, starting in the 11th and 12th centuries was due to much Sicilian, Jewish, and Greek settlement, alongside many other immigrants from neighbouring cities in southern Italy.^[19] With the loss of many Italian trading posts in the Orient, the import of Chinese styles drastically declined. Gaining momentum, in order to satisfy the rich and powerful bourgeoisie's demands for luxury fabrics, the cities of Lucca, Genoa, Venice and Florence were soon exporting silk to all of Europe. In 1472, there were 84 workshops and at least 7000 craftsmen in Florence alone.

Reciprocal influences

Silk, which had a reputation of being a Chinese textile, was in fact made throughout the region of Eurasia, using various breeds of lepidopterans, both wild and domestic. There is no doubt that the Chinese were the first to begin production on such a large scale, having the most effective breed for silk production, the bombyx mori. Chinese sources claim the existence of a machine to unwind silkworm cocoons in 1090. The cocoons were placed in a large basin of hot water, the silk would leave the cauldron by tiny guiding rings, and would be wound onto a large spool, thanks to a backwards and forward motion.^[20] Little information exists about spinning techniques in use in China. The spinning wheel, in all likelihood moved by hand, was known by the beginning of the Christian era. The first accepted image of a spinning wheel appears in 1210. There is an image of a silk spinning machine powered by a water wheel that dates to 1313.

More information is known about the looms used. The Album of Agriculture and Sericulture, compiled ca 1210, is rich with pictures and descriptions, mostly pertaining to silk. It repeatedly claims the Chinese looms to be far superior to all others. It speaks of two types of loom that leave the worker's arms free: the drawing loom, which could have either a Chinese or European origin, and the pedal loom which is attributed to the Chinese. The many diagrams originate in the 12th and 13th centuries. When examined closely, many similarities with European machines of that epoch can be seen. Since the Jin dynasty, the existence of silk damasks has been well recorded, and since the 2nd century BC, four-shafted looms and other innovations allowed the creation of silk brocades.

Silk in the medieval world

A more abundant luxury

The high Middle Ages saw continued use of established techniques for silk manufacture without any changes to speak of, neither in materials nor in tools used. Between the tenth and twelfth centuries, small changes began to appear, though the changes of the thirteenth century were much larger and more radical. In a short time, new fabrics began to appear; hemp and cotton each also had their own particular techniques of manufacture. Known since Roman times, silk remained a rare and expensive material. Byzantine magnaneries in Greece and Syria (6th to 8th century), and those of the Arabs in Sicily and Spain (8th to 10th century) were able to supply the luxury material in a much greater abundance.

Improved technology

The 13th century saw an already changing technology undergo many dramatic changes. It is possible that, as with in England at the end of the 18th century, advances in the textile industry were a driving force behind advances in technology as a whole. Silk indeed occupies a privileged place in history on account of this.^[21]

At the start of the thirteenth century, a primitive form of milling the silk threads was already in use. In 1221, Jean de Garlande's dictionary, and in 1226, Étienne Boileau's Livre des métiers (Tradesman's Handbook) enumerated many types of devices which can only have been doubling machines. The instruments used were further perfected in Bologna between 1270 and 1280. From the start of the fourteenth century, many documents allude to the use of devices that were quite complex.^[22]

The reel, originally developed for the silk industry, now has multiple uses. The earliest surviving depiction of a spinning wheel is a panel of stained glass in the Cathedral of Chartres.^[23] Bobbins and warping machines appear together in the stained glass at Chartres and in a fresco in the Cologne Kunkelhaus (ca 1300). It is possible that the toothed warping machine was created by the silk industry; it allowed the warp to be more uniform and allowed the warp to be of a longer length.^[24]

Starting at the end of the 14th century, no doubt on account of the devastation caused mid-century by the Black Death, there was a general shift towards less expensive techniques. Many things which would have earlier been completely forbidden by the guilds were now commonplace (using low quality wool, carding, etc.). In the silk industry, the use of water-powered mills grew, and by the 15th century, the loom designed by Jean le Calabrais saw nearly universal use.^[25]

The Silk industry in France

Italian silk cloth was very expensive, as much a result of the cost of the raw material as of the production costs. The craftsmen in Italy proved unable to keep up with the exigencies of French fashion, which continuously demanded lighter and less expensive materials.^[26] These materials were used for clothing, and garment production began to be done locally. Nevertheless, Italian silk long remained among the most prized, mostly for furnishings and the brilliant colours of the dyes.

Following the example of the wealthy Italian city-states of the era (Venice, Florence, Lucca, etc.), which had become the centre of the luxury textile industry, Lyon obtained a similar function in the French market. In 1466, King Louis XI decided to develop a national silk industry in Lyon. In the face of protests by the Lyonnais, he conceded and moved the silk fabrication to Tours, but the industry in Tours stayed relatively marginal. His main objective was to reduce France's trade deficit with Italy, which caused France to lose 400,000 to 500,000 golden écus a year.^[27] It was under Francis I in around 1535 that a royal charter was granted to two merchants, Étienne Turquet and Barthélemy Naris, to develop a silk trade in Lyon. In 1540, the king granted a monopoly on silk production to the city of Lyon. Starting in the 16th century, Lyon became the capital of the European silk trade, notably producing many reputable fashions.^[28] Gaining confidence, the silks produced in the city little by little began to abandon the original oriental styles and moved towards their own distinctive style, with an emphasis on landscapes. Thousand of workers, the canuts, devoted themselves to the flourishing industry. In the middle of the 17th century, over 14,000 looms were in use in Lyon, and the silk industry fed a third of the city's population.^[28]

In the 18th and 19th centuries, Provence experienced a boom in sericulture that would last until the First World War, with much of the silk produced being shipped north to Lyon. Viens and La Bastide-des-Jourdans are two of the communes of Luberon that profited the most from mulberry plantations that have since disappeared.^[29] Working at home under the domestic system, silk spinning and silk treatment employed many people and increased the income of the working class.

Spread to other countries

England under Henry IV was also looking to develop a silk industry, but no opportunity arose until the 1560s when hundreds of thousands of French Huguenots, many of which were skilled weavers and experts in sericulture, began immigrating to England to escape religious persecution. Some cities, including Spitalfields saw many high-quality silk workshops spring up, their products distinct from continental silk largely by the colours used.^[30] Nonetheless, the British climate prevented England's domestic silk trade from becoming globally dominant.

Many envisioned starting a silk industry in the Thirteen Colonies, starting in 1619 under the reign of King James I of England. The silk industry in the Thirteen Colonies never became very large. Likewise, silk was introduced to numerous other countries, including Mexico, where it was brought by Cortez in 1522. Only rarely did these new silk industries grow to any significant size.^[31]

Silk since the Industrial Revolution

The start of the Industrial Revolution

The start of the Industrial Revolution was marked by a massive boom in the textile industry, with remarkable technological innovations made, led by the cotton industry of Great Britain. In its early years, there were often disparities in technological innovation between different stages of fabric manufacture, which encouraged complimentary innovations. For example, spinning progressed much more rapidly than weaving.

The silk industry, however, did not gain any benefit from innovations in spinning, as silk is naturally already a thread. Making silk, silver, and gold brocards is a very delicate and precise process, with each colour needing its own dedicated shuttle. In the 17th century and 18th centuries, progress began to be made in the simplification and standardization of silk manufacture, with many advances following one after another. Bouchon and Falcon's punchcard loom appeared in 1775, later improved on by Jacques de Vaucanson. Later, Joseph-Marie Jacquard improved on the designs of Falcon and Vaucanson, introducing the revolutionary Jacquard loom, which allowed a string of punchcards to be processed mechanically in the correct sequence.^[32] Due to the effectiveness of the Jacquard loom, from 1801 embroidery became highly mechanized. The mechanism behind the Jacquard loom even allowed complex designs to be mass produced.

The Jacquard loom was immediately denounced by workers, who accused it of causing unemployment, but soon it had become vital to the industry. The loom was declared public property in 1806, and Jacquard was rewarded with a pension and a royalty on each machine. In 1834, there were a total of 2885 Jacquard looms in Lyon alone.^[28] The Canut Uprising in 1831 foreshadowed many of the larger worker uprisings of the Industrial Revolution. The canuts occupied the city of Lyon, and would not relinquish it until a bloody repression by the army, led by Marshal Soult. A second revolt, similar to the first, took place in 1834.

Decline in the European silk industry

The first silkworm diseases began to appear in 1845, creating an epidemic. Among them are pébrine, caused by the bacteria Nosema bombycis, grasserie, caused by a virus, flacherie caused by eating infected mulberry leaves or white muscardine disease, caused by the fungus beauveria bassiana. The epidemic grew to a massive scale, and after having attacked the silkworms, other viruses began to infect the mulberry trees. The chemist Jean-Baptiste Dumas, French minister of agriculture, was charged with stopping the epidemic. In face of sericulturers' call for help, he asked Louis Pasteur to study the disease, starting in 1865. For many years, Pasteur thought that pébrine was not a contagious disease. In 1870, he changed his view, and measures were enacted that caused the disease to decline.

Nevertheless, the increase in the price of silkworm cocoons and the reduction in importance of silk in the garments of the bourgeoisie in the 19th century caused the decline of the silk industry in Europe. The opening of the Suez Canal in 1869 and the silk shortage in France reduced the price of importing Asian silk, particularly from China and Japan.^[33]

Starting from the Long Depression (1873 – 1896), Lyonnais silk production had become totally industrialized, and hand looms were rapidly disappearing. The 19th century saw the textile industry's progress caused by advances in chemistry. The synthesis of aniline was used to make mauveine (aniline purple) dye and the synthesis of quinine was used to make indigo dye. In 1884, Count Hilaire de Chardonnet invented artificial silk and in 1891 opened a factory dedicated to the production of artificial silk (viscose), which cost much less and in part replaced natural silk.

Silk in modern times

Following the crisis in Europe, the modernization of sericulture in Japan made it the world's foremost silk producer. Italy managed to rebound from the crisis, but France was never able to. Asian countries, formerly exporters of raw materials (cocoons and raw silk), progressively began to export more and more finished garments.

Since the Second World War, synthetic fibres such as nylon have further reduced world demand for silk, though silk remained an expensive luxury product. With its recent economic reforms, the People's Republic of China has become the world's largest silk producer. In 1996, it produced 58,000 tonnes out of a world production of 81,000, followed by India at 13,000 tonnes. Japanese production is now marginal, at only 2500 tonnes. Between 1995 and 1997, Chinese silk production went down 40% in an effort to raise prices, reminiscent of earlier shortages.^[34] World demand for silk in the 1990s stayed fairly low with the exception of a few markets, including India and the United Kingdom. Silk's image suffered on account of distribution of low quality fabric, though it has improved recently. Today, the silk trade is largely dependent on a few consuming countries, including India and Japan.
