PASSAGE

Tondanuru in Karnataka’s Mandya District, popularly known as Kere Tonnur, has been associated with Sri Ramanujacharya. Tondanuru literally means the place of devotees. It was a flourishing centre of Sri Vaishnava faith and philosophy. Ramanujacharya lived here in the early 12th century and propagated his teachings.

There are over 70 inscriptions found here dating from pre-Hoysala period to the Mysore Wodeyar. Interestingly, a majority of the inscriptions are written in Tamil, in grantha script. It attests to the frequent visits here by Sri Vaishnava devotees from TamilNadu.

The history of Tonnuru can be traced to the prehistoric period as megalithic burial sites have been found in the region. It has been under the control of the gangas of Talakad, Cholas and the Hoysalas and later came under the Vijayanagara, Mysore Wodeyar, and also Hyder Ali and Tipu Sultan. Hoysala chronicles record Tonnura as one of the sub-capital of the period.

The village of Tonnuru in Pandavapura taluk, around 130 km from Bengaluru, is situated amidst fertile paddy fields, coconut groves and a large pond that supplies water for agriculture, with granite hills all around. Local traditions ascribe the excavation of the pond to Ramanujacharya, who also created a channel for water supply.

The religious importance of Tonnur was enhanced by the stay of Sri Ramanujacharya. Tonnuru temples dedicated to the Vaishnavite faith were built or renovated during his presence. It is clear from records that Ramanuja came to Tonnur after Hoysala king Bittiga, who ruled in the 12th century became Vishnuvardhna and an ardent follower of Vishishtadvaita philosophy. Ramanuja’s teachings persuaded many people of the region to become his followers. Later, he moved to Melgate where he stayed for a long period. Sri Yatiraja Dasa became his follower and propagated his teachings.

Question:

The inscriptions found in Tonnuru are of which script?
