ment those on a series of openwork plaques, some of them of Ordos origin, on which either two dismounted riders are shown fighting while their horses stand passively on either side or two horses are seen locked in battle, pursuing their masters' quarrel (State Hermitage Museum).Mongolian Huns (Hun)In the 4th century BC the Huns started to migrate westward from the Ordos region. By the 3rd century BC they had reached the Transbaikalia and had begun to enter Mongolia, which soon became the centre of their empire. Many mounds mark their progress. Those in the Zidzha Valley lie at the same latitude as the Pazyryk mounds and were subjected to similar conditions of freezing, which helped preserve their contents. The richest of the excavated burial sites, however, are those of Noin Ula, to the north of Ulaanbaatar, on the Selenge River. Like those at Pazyryk, they included horse burials. The furnishings of one tomb were especially lavish. The prince for whom it was made must have been in contact with China, for his coffin was apparently made for him there, as were some of his possessions buried with him (e.g., a lacquer cup inscribed with the name of its Chinese maker and dated September 5, AD 13, now in the State Hermitage Museum). His horse trappings (State Hermitage Museum) are as elaborately decorated as many of those found at Pazyryk. His saddle was covered with leather threaded with black and red wool clipped to resemble velvet. The magnificent textiles in his tomb included a woven wool rug (rug and carpet) lined with thin leather (State Hermitage Museum); the centre of the rug depicts combat, of Scytho-Altaic character, between a griffin and an elk, executed in purple, brown, and white felt appliqué work. The animals' bodies are outlined in cord and embroidered. The design on another textile is embroidered in the form of a tiger skin with a head at each end. The animal's splayed-out body is formed of black and white embroidered stripes. Other textiles are of Greco-Bactrian and Parthian origin. In some of the Parthian fragments, Central Asian and Sāsānian Persian influences prevail over Hellenistic ones.Tashtyk tribeOn the Yenisey River the Bronze Age Tagar culture was replaced by the Tashtyk culture, dating from the 1st to the 4th century AD. The physical appearance of the Tashtyk people has been preserved by a seriesof masks (mask), some of them modelled, others cast from the dead. They were painted with the features rendered in blue, red, and green against a yellow ground. Spirals disposed on the foreheads, temples, and cheeks of many of these masks probably represent tattoos. In many cases pearl necklaces worn by the women are also included. Although the animal motifs of the Tashtyks remained strongly Scytho-Altaic in style, the community was so much influenced by China that even its architecture was affected. Just south of Abakan, a large house made of beaten clay in the Chinese style has been discovered. Its roof had been covered with Chinese tiles, some of which carry inscriptions of the Han dynasty.The Parthian empire came into being in Khorāsān during the reign of Seleucus I, 358–281 BC, following the absorption by the Parthians of Parni (Dahae) tribesmen. The caravans traversing their territory brought them wealth and ideas from abroad. The figural art of the Hellenistic world made an especially strong impression on them. The finest Parthian objects come from Old Nisa, a town situated on the edge of the Karakoram Range, some 11 miles (18 kilometres) south of Ashkhabad in Tajikistan, close to the later town of New Nisa. Old Nisa was founded around 171 BC by Mithradates I to serve as a royal Parthian residence and necropolis, as well as the kingdom's capital. It contained several fine temples and an impressive palace built around a vast central hall, the roof of which was upheld by wooden supports set in stone bases—a practice followed in the town's larger houses. Life-size clay statues of men and women stood between these supports. The royal treasuries contained many valuables, including silver and silver gilt st
