the necklaces formed of small openwork plaques linked by rings or chains.Following the Russian Revolution, a new phase of art began in the Soviet-controlled regions of Central Asia. Although the Soviet authorities took steps to maintain the existing carpet and textile industries, they encouraged the inclusion of genre scenes and native animals and vegetation. They also founded schools to train artists in the traditions of European art. Pictorial arts are naturalistic in style, conforming with the principles of social realism as defined by the Soviet authorities. The first Buryat-Mongolian Turkmen (Turkic peoples) painter to achieve distinction in this style was Tsyrenzhap Sampilov.Arctic regionsIn the arctic zone of Central Asia, the prehistoric age extends from the 3rd millennium BC to the arrival of Europeans around AD 1800. Knowledge of the region's arts is still very limited, for it is wholly dependent upon the sculptures produced by Eskimos (Eskimo) living on the shores and in the hinterland of Siberia and the Bering Strait. These sculptures are mostly in walrus tusk, though wood and reindeer horn examples also exist. The majority are small in size and worked in the round to form terminal ornaments for utilitarian or ceremonial objects or statuettes. The latter are not provided with bases and thus must have been designed to be carried about. Many of the implements are decorated with incised patterns formed chiefly of lines and dots. As in all early arts, the statuettes and terminal ornaments are largely concerned with hunting or the magical practices of shamanism. The earliest and finest statuettes of which there is knowledge are assigned to the Okvik culture, which some scholars date to the pre-Christian era, but which others assign to its early centuries. Okvik art is concerned primarily with the representation of the human figure, differing in that respect from the contemporary or slightly later Old Bering Sea culture, where interest largely centres on animals, such as reindeer, elks, bears, and seals.Works of the Okvik and later Arctic schools often depict women, sometimes in the nude, sometimes clothed. The nude figures seldom include more of the arms than shoulder stumps. Their bodies are short and flat, their heads large, pear-shaped, and carefully worked, as are hands when included. The faces are carved and are sometimes incised with lines, probably denoting tattooing. The so-called Okvik Madonna (University of Alaska Museum, Fairbanks) is perhaps the most expressive of these statuettes.Some Okvik animal designs are particularly interesting because of certain stylistic details that point to a relationship with works of the Scytho-Siberian school. reindeer are so frequently depicted that the discovery at Pazyryk of a horse's mask in the form of a reindeer's head led to the suggestion that the mask was a survival from a reindeer cult acquired by the Altaians from a northern people such as the Eskimo. That theory has been discounted, yet some Okvik works are undoubtedly related to certain slightly older examples of Siberian metalwork. Thus, the heads of some terminal ornaments bear a close resemblance to those of certain Siberian works. The lozenge-shaped muscles that appear on Eskimo carvings amid lines intended to portray the animal's skeleton are very similar to those of the Pazyryk dot and comma markings. In late- or post-Okvik times certain specifically Eskimo objects, such as masks, were decorated with stylized animal heads executed in relief and accompanied by bosses that recall the Altaic, especially those that reflect Chinese influence. Compositions such as that on an unidentifiable object (possibly a rake or comb) in the University of Alaska Museum, which includes as its central motif the head of an animal resembling a bear or a seal, display a marked affinity with west Siberian ones.Climatic changes in the 17th century led to contacts with the outer world in the 19th century and brought the traditional Eskimo school of sculpture to an abrupt end. When, toward the end of the century, art started to re
