Mr.anuragawasthi, I really wonder from where on earth you are getting all sorts of absurd informations? The Greek Traveller's name you mentioned is incorrect and the Mathura referred to in that is located in UP (not Madura in TN). On another Site you were talking about some obscure language of Baluchistan was also "dravidian" Why it should not be the other way round? People from that part of Indian sub-continent migrated to TN?
