The pink sandstone Hindu, Jain and Buddhist sculptures of Mathura from the 1st to 3rd centuries CE reflected both native Indian traditions and the Western influences received through the Greco-Buddhist art of Gandhara, and effectively established the basis for subsequent Indian religious sculpture. The style was developed and diffused through most of India under the Gupta Empire (c. 320-550) which remains a "classical" period for Indian sculpture, covering the earlier Ellora Caves, though the Elephanta Caves are probably slightly later. Later large scale sculpture remains almost exclusively religious, and generally rather conservative, often reverting to simple frontal standing poses for deities, though the attendant spirits such as apsaras and yakshi often have sensuously curving poses. Carving is often highly detailed, with an intricate backing behind the main figure in high relief. The celebrated 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.
