Arjuna ' s penance Mahabalipuram These bas-reliefs, carved in the 7th century, are among the largest in the world. Completely covering two huge boulders 27 meters long and 9 meters high, the reliefs depict the flow of the Ganges down from the Himalaya mountains as described in the Panchatantra. The story is a flood myth like the tale of Noah, but differs in its cast of characters. Legend says that King Bhagirath brought down the Ganges from Heaven to purify the souls of his ancestors. His plan went awry when he realized that the flood would innundate the earth, so he had to undergo a penance to convince Shiva to intervene, who came down to earth and let the flood trickle through his hair, dispersing the waters safely in innumerable streams all over the world. This strange sight aroused the curiousity of the world's animals, who gathered round the soaking God.
