Please read this article in the Hindu http://www.thehindu.com/arts/history-and-culture/article3862692.ece?homepage=true � It gives a lot of information about the temple at the village Natham Kovilpatti. There is a lot of information shared about the paintings in the Temple and a special information that in Maguda Agama the�worship starts with Shiva and ends with Nandi not like the regular agamas where worship starts with vinayaka. I think Tanjavur Big Temple is built according to in Maguda Agama. Nice article. �
