d)) sites were discovered in what was formerly Soviet Central Asia, and the number of Bronze Age sites is even higher. The majority were found on the middle reaches of the Yenisey River, especially in the Minusinsk Basin, where metallurgy developed early. They testify to the existence of three main, basically successive, yet often overlapping cultures: the Afanasyevskaya, Andronovo, and Karasuk, so called after the villages near which each culture was identified.A cemetery to the southwest of Krasnoyarsk, on the slopes of the Afanasyevskaya Mountains, contained 80 burials dating from the 2nd millennium BC. The earlier ones were flat and marked by stone circles symbolizing the Sun god; the later ones took the form of barrows, or large mounds of earth, but were also encircled by similar stone slabs. The earlier graves (tomb) contained elongated, spherical pottery vessels with pointed bases decorated with herringbone patterns. In the later graves this type of ware was superseded by flat-bottomed pots usually associated with sedentary pastoralist cultures. The graves also contained numerous stone and bone objects. Although copper objects were rare, they heralded the dawn of a new cultural period, the Metal Age.The Andronovo culture succeeded the Afanasyevskaya in the 2nd and 1st millennia BC. Although found to the southwest of Krasnoyarsk, it is more frequently encountered in western Siberia and Kazakhstan. The settlement and cemetery of Alekseevskoe (present Tenlyk), some 400 miles (600 kilometres) south of Yekaterinburg (formerly Sverdlovsk), is especially important, because its earth houses were designed for permanent habitation. Their roofs rested on logs, and each dwelling had a central hearth used for heating purposes with side hearths intended for cooking. Bronze objects were numerous, and workshops existed for working copper. The metal probably came from mines in the Minusinsk Basin, Kazakhstan, and the western Altai Mountains, the latter having been worked as early as the 14th century BC.Dating from about 1200 to about 70 BC—the dawn of the Iron (Iron Age) and historical age—the Karasuk culture was located in the Minusinsk Basin, on the Yenisey River and on the upper reaches of the Ob River. Its creators must have been in touch with East Asia, for certain bronze objects, notably elbow-shaped knives, are related to those used between the 14th and 11th centuries BC in China during the Shang period. Stone pillars topped either with ram's heads, stylized animal forms, or human figures have also been discovered. Dzheytun, northwest of Ashgabat (Ashkhabad) in the Kyzylkum Desert, is the oldest known agricultural settlement in Central Asia. It possessed a thriving Neolithic flint industry.Annau, six miles (10 kilometres) southeast of Ashgabat and Namazga-Tepe, situated in the same region and occupying an area of some 145 acres (60 hectares), are important Bronze Age sites. The pottery vessels recovered from Namazga-Tepe are decorated with painted plant and animal motifs showing affinities with contemporary pottery wares from the Middle East. Figurines of dogs and sheep were numerous, and a model of a house has also been found. At Karatepe, also near Ashgabat, an agricultural society produced fine pottery from the 3rd millennium BC, but it reached its fullest development in the 2nd millennium BC in a series of vessels decorated with particularly spirited animal designs.The main Neolithic and Bronze Age cultures produced several distinctive offshoots, which began to emerge by the early Iron Age. In Chorasmia (Khwārezm) the Neolithic culture discovered at Dzhan-Bas-Kala is known as the Kelteminar, and that of the Bronze Age, as represented by the Chorasmian level of Kokcha III, as the Tazabagyab. The Neolithic Hissar culture of southern Tajikistan spread across northeastern Central Asia into the Semirechiye, or foothills of the Tien Shan, while in Siberia the Bronze Age Karasuk culture was replaced in the 8th century BC by the Tagar culture. The latter endured until the 2nd century BC, producing an art of animal motifs relate
