Descent of the Ganges at Mahabalipuram, in the Tamil Nadu state India, is one of a group of monuments that were designated as a World Heritage Site since 1984. Measuring long by high, it is a giant open-air relief carved of the a monolithic rock. The monuments and sanctuaries were built by the Pallava kings in the 7th and 8th centuries. The legend depicted in the relief is the story of the descent of the sacred river Ganga to earth from the heavens led by Bhagirata. The waters of Ganges are believed to possess supernatural powers. The descent of the Ganges and Arjuna's Penance are portrayed in stone at the Pallava heritage site
The bas relief is situated on a rock with a cleft. Above the cleft was a collecting pool, and at one time, water may have flowed along the cleft. Figures within the cleft are said to represent Ganga or the River Ganges and Shiva. This provides the basis for an alternative interpretation of the mural. Rather than Arjuna, the figure performing austerities is said to be Bhagiratha. Bhagiratha is said to have performed austerities so that Ganga might descend to earth and wash over the ashes of his relatives, releasing them from their sins. To break Ganga's fall from heaven to earth, she falls onto Shiva's hair, and is divided into many streams by his tresses.
