There are three 2nd century C.E. Jain inscriptions in Arachalur, which Dr. S. Raju discovered. On a Jain bed in the Arachalur hills, is an inscription — ‘ezhuthum punaruthan maniya vannakkan devan sathan.’ The word ‘punaruthan’ is an alteration of punarthan, which means organised. The other two inscriptions have musical syllables, which are the same when read from left to right, and vice versa; they are also the same when read from the top of a column to the bottom and vice versa. These two inscriptions show that 'Maniyan Vannakkan Devan Sathan' organised musical syllables. “This inscription, which belongs to the same period as Silappadikaram, is centuries older than the 'Kudumiyamalai inscriptions' on music, and yet the Arachalur inscription hardly draws visitors,” rues Dr.S. Raju. Dr. S. Raju says that the contribution of Kongu Jains to Tamil was immense. “Konguvelir, who wrote Perunkathai, based on Durvineetha’s Brihatkatha, must have been a Kongu Vellala Jain. A Sanskrit inscription in the Vijayamangalam Jain temple, talks of the beauty of Perunkathai. This temple was built in 678 C.E. So Konguvelir must have lived in Vijayamangalam around this time.”
