The Agastyesvara temple at Perungudi in the past was known as Tiruppermudi Paramesvaram. There are contrary opinions on the patronage of the temple. Although, the earliest inscription on the temple registers a gift in the reign of Aditya II (960-965 CE), which was part of his father, Sundara Chola’s reign (957-973 CE), it has also been suggested in scholarly debates that despite the hard style of the sculptures and their atavistic tendencies, the temple is not earlier than the time of Rajendra Chola (1014-1044 CE) especially since the reign of Sundara Chola and Aditya II was artistically bleak.
