Arjuna's Penance:
An enormous open-air bas-relief made on two huge boulders at Mahabalipuram, Arjuna's Penance is a sculptural marvel. It is 31 m long and 9 m high and its surface has detailed carvings depicting animals, as they would appear in their natural surroundings. There is a controversy as to the origins of this bas-relief. While some believe that it shows Arjuna undertaking a penance to obtain a rare weapon against his enemies, others believe that it depicts Bhagiratha in penance to bring River Ganges to earth. According to the latter, cleft appeared in the rock dividing the canvas in two, symbolizing the Shiva's response to Bhagiratha's penance. According to Ferguson and Burgess, the sculptured 'Nagas' on the cleft suggests that this bas-relief represents 'Serpent Worship' prevalent in ancient India.
Rock Fort Temple:
The Rock Fort temple at Tiruchirappalli or Trichy is said to have three main temples that include the Manikka Vinayaka temple at the foot of the hill, the Uchhi Pillayar Koyil at the top of the hill and the Taayumaanava Koyil or Shivastalam on the hill. However, the Shivastalam is most prominent of all. This rock-cut temple can be reached by a flight of steps and is on the way to the famous Ucchi Pillaya temple at the top. It enshrines Kangaala Moorthy, one of the 64 manifestations of Shiva. The 83 m high Rock Fort is perched atop the only outcrop in city that rises abruptly towering over the city. It is said that the rock is about 3,800 million years old and is one of the oldest in the world. It is said to be made up of quartz and felspar.
