The Silk road is the name for the trade route between the Mediterranean Sea and China. The first users of the road must have lived in the first half of the first millennium BCE, but the name "Silk Road" is recent. Its most famous traveler lived more than twelve hundred years later: Marco Polo of Venice (1254-1324).
From Sâveh, the road continued to Rhagae (Tehrân), the religious capital of ancient Media. Further to the east, it passed through Parthia and reached Hecatompylos (Šahr-e Qûmes near Dâmghân) and Susia (Tûs near Mashad). To the north, one saw the Elburz mountains, to the south, the desert. At Susia, the road forked. The southern branch went through the Arian capital Artacoana (Herât) to Kapisa (Kandahâr) in Arachosia, and from there either to the southeast to the Lower Indus or to the northwest to Gandara (the valley of the Kabul) and the Punjab.
The northern branch went from Susia through the Karakum desert, passing along the oasis Margiana (Mary or Merv) and the Scythian tribes along the Amudar'ya, to Maracanda (Samarkand) in Sogdia or to Bactra (Balkh, near modern Mazâr-e Sharîf) and Drapsaca (Kondûz). Here, lapislazuli could be found, a precious article that was much appreciated in Babylonia and Assyria. Other articles that were traded were the famous 'blood sweating' horses of the Ferghana valley, and hairy camels from the Gobi desert.
Almost no one traveled beyond Drapsaca, but a few continued upstream along the Amudar'ya. The most important towns along this road were modern Tâloqân, Feyzâbâd, and Eshkâshem. The traveler had now reached Wakshan, a small strip of land along the upper Amudar'ya, which is also called Ab-i-Panja. At the eastern end of this valley, he had to climb the Pamir mountains -the pass is 4,923 meters high- after which he reached a place named Stone Tower. It is probably identical to Taxkorgan and it seems to have been the place where westerners bartered their goods with the products from the Far East. Here, a second trade route joined the Silk road: across the Khunjerab pass, one could go to Kashmir and the capital of the Punjab, Taxila.
Another exchange point between westerners and Chinese was modern Kashi, an oasis in Xinjiang. It was reached by a more northerly branch of the Silk road.
When the Chinese traders went home, they first passed along the Desert Without Return (Taklamakan), obtained jade in Khotan, and reached the Jade Gate (Yumen), which is traditionally viewed as the western end of the Great Wall. From here, they continued to modern Lanzhou, from where they could go to Chang'an, the City of Eternal Peace, which may be regarded as the last station of the road.
Chang'an was the capital of China under the rule of he emperors of the Han dynasty (206 BCE - 220 CE). Under the emperor Wu Di (141-87), the Silk road was really opened. This ruler had to campaign against the Hsiung-nu nomads in the north -they are the ancestors of the Huns- and c.130 he sent out his general Zang Qian to find allies and to buy the famous Iranian war horses from Nisaia. Although Zang Qian failed in his mission, he had visited Bactria and had found the way to the west.
Trade was made easier when the Chinese acquired Xinjiang (also called Chinese Turkestan) in 104-102 BCE. The caravans received some protection from the authorities for a substantial part of their route. Moreover, bridges and paved roads were constructed. Beyond the Jade Gate, the political situation was more complex: the Pamirs were dominated by sometimes aggressive mountain tribes and the empires of the Parthians and Seleucids were fighting a more or less permanent war. Nonetheless, the Chinese received horses and other valuable articles -myrrh, frankincense, ostrich eggs, glass, furs, aloe, gemstones- from the west; and the Parthians, Seleucids, Greeks and Romans acquired ceramics and bales of silk, which had been carried by donkeys, mules, horses, yaks and camels for almost thousands of kilometers. (An overview of road stations can be found in the Mansiones Parthicae by Isidore of Charax.)
In the West, silk was considered more precious than gold and it remained very rare and expensive. To the best of our knowledge, the Roman emperor Heliogabalus (218-222) was the only Roman to wear a dress of pure silk. The westerners called the Chinese simply the Silk People (Seres); the capital of the Han dynasty, Chang'an, was known as Silk City.
When the Han dynasty collapsed in the third century, the trade between east and west was reduced to a minimum. According to the Byzantine historian Procopius (c.500-c.570), two Christian monks discovered the secret of the silk production. The emperor Justinian (527-565) immediately dispatched secret agents to steal silkworm eggs and to bribe silk experts. They were successful, and from this time onward, silk was also produced in the Mediterranean.
This was not the end of the Silk Route, however, because the West remained interested in buying gums and spices. When the T'ang (618-907) dynasty restabilized China, the long-distance trade route was reanimated. It became a road to spread Christianity as well: in 635, Nestorian missionaries from Ctesiphon reached China. As we have already seen, its most famous traveler was Marco Polo, whose story is invaluable.
