Valmiki Ramayana, the epic that speaks of Sri Rama mentions Kavata, Kapatapuram in Tamil,and Pandya Kingdom. Kishkindha kandam also refers to Cheras,Cholas,Andhras as well
Puranas and Ithihasas,Ramayana and Mahabharatha are dismissed because they are religious texts(?). Yet they would accept the Bible! Rama's ancestor Sibi,a Chola King built the Thiruvellarai Temple,about 10 km from Srirangam,Tamil Nadu in honour of Lord Vishnu as Pundarikaksha.
