 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.
