lost wax bronzes of the Chola dynasty (c. 850–1250) from south India, many designed to be carried in processions, include the iconic form of Shiva as Nataraja, with the massive granite carvings of Mahabalipuram dating from the previous Pallava dynasty. The Chola period is also remarkable for its sculptures and bronzes. Among the existing specimens in the various museums of the world and in the temples of South India may be seen many fine figures of Siva in various forms, Vishnu and his wife Lakshmi, Siva saints and many more. Wall painting The tradition and methods of Indian cliff painting gradually evolved throughout many thousands of years – there are multiple locations found with prehistoric art. The early caves included overhanging rock decorated with rock-cut art and the use of natural caves during the Mesolithic period (6000 BCE). Their use has continued in some areas into historic times. The Rock Shelters of Bhimbetka are on the edge of the Deccan Plateau where deep erosion has left huge sandstone outcrops. The many caves and grottos found there contain primitive tools and decorative rock paintings that reflect the ancient tradition of human interaction with their landscape, an interaction that continues to this day. The oldest surviving frescoes of the historical period have been preserved in the Ajanta Caves with Cave 10 having some from the 1st century CE, though the larger and more famous groups are from the 5th century. Despite climatic conditions that tend to work against the survival of older paintings, in total there are known more than 20 locations in India with paintings and traces of former paintings of ancient and early medieval times (up to the 8th to 10th centuries CE), although these are just a tiny fraction of what would have once existed. The most significant frescoes of the ancient and early medieval period are found in the Ajanta, Bagh, Ellora, and Sittanavasal caves, the last being Jain of the 7th-10th centuries. Although many show evidence of being by artists mainly used to decorating palaces, no early secular wall-paintings survive. The Chola fresco paintings were discovered in 1931 within the circumambulatory passage of the Brihadisvara Temple at Thanjavur, Tamil Nadu, and are the first Chola specimens discovered. Researchers have discovered the technique used in these frescoes. A smooth batter of limestone mixture is applied over the stones, which took two to three days to set. Within that
