frescoes on the sanctum walls along the circumambulatory pathway. These frescoes which cover floor to ceiling, were discovered in 1931 by S. K. Govindasami of the Annamalai University. The painters used natural pigments and infused it into the wet limestone layer as it was setting in. The Chola frescoes were largely of Shaivism themes. These were restored in the 2000s. The total Chola fresco area is about , of which about had been uncovered as of 2010 in a method that preserves both paintings, a technique developed by Archaeological Survey of India. The frescoes narrate Hindu mythology. According to Balasubrahmanyam, most frescoes are related to Shiva, but the 11th century Chola frescoes also show Vishnu, Durga and others, as well as scenes of Chola royalty, courtly and common life. The later constructions, additions and modifications to the temple curtailed the amount of natural light inside the temple. The frescoes were thus photographed in a limited way and interpreted. According to Sriraman, a complete imaging with better photographic equipment suggests that these historic interpretations were incorrect. For example, a fresco that was previously interpreted as Dakshinamurti Shiva is actually a secular scene of a royal guru meditating under a banyan tree. On the tree are shown peacocks, birds, monkeys, squirrels and owls, plus a cobra. The animals and birds are shown as worried of the cobra, the one's closer to the snake are shown to be more worried. Other parts of the panel similarly show a court listening to a saint. Other show women in different dresses in different dance mudra. Some of the paintings in the sanctum sanctorum and the walls in the passage had been damaged because of the soot that had deposited on them once upon a time. Owing to the continuous exposure to smoke and soot from the lamps and burning of camphor in the sanctum sanctorum over a period of centuries certain parts of the Chola paintings on the circumambulatory passage walls had been badly damaged. The Archaeological Survey of India, for the first time in the world, used its unique de-stucco process to restore 16 Nayak paintings, which were superimposed on 1000-year-old Chola frescoes. These 400-year-old paintings have been mounted on fibre glass boards, displayed at a separate pavilion. Inscriptions The temple walls have numerous inscriptions in Tamil and Grantha scripts. Many of these begin with customary Sanskrit and Tamil language historical introduction to the
