For example Appar has captured the traditions of Thiruvarur in his Thevaram "Ambalathu Mannikoothai Aaduvan Puguvadarkku Munno Pinno." See my article "Timeless Thiruvarur" at http://www.whatisindia.com/monuments...hiruvarur.html. He has also talked about the music and prevalence of art in Thiruvaiyaru in a different Thevaram.
