As per Hindu legend, Shiva appeared for a staunch devotee in the form of her mother to help her delivery. To quench her thirst, Shiva is believed to have split his toe nail that resulted in a spring in the form of Siddhamritha tank. As per local legend, the Nayak king Thirumalai Nayak suffered from stomach pain and he arrived at Madavar Vilagam in an ivory palanquin and stayed there for 48 days. He was completely cured and as a mark of his gratitude, he constructed the Natarajar hall as in Madurai Meenakshi temple. He also built drum halls from the temple in Madurai as he would take his midday meal only after hearing the drum sounds indicating the completion of mid day worship in the temple. There are many inscriptions in the temple from the Pandya dynasty and Thirumalai Nayak indicating various grants to the temple. The Pandya inscriptions refer the temple name as Thirukkattralishvaram Udaiyar.
