"Timothy Brook and Andre Schmid, in their work on the creation of identities in Asia, explain Caldwell's importance as the founder of today's Dravidian identity: It was through his Comparative Grammar (1856) that he systematically laid the foundation of Dravidian ideology . . . It was not so much the philological findings in the work that had such a profound impact, as the way Caldwell interpreted and expressed them in the lengthy introduction and appendix. He not only managed to erect a racial, linguistic, and religio-cultural divide between the minority Brahmin and majority non-Brahmin (Dravidian) population of South India, but also provided a systematic project for reclaiming and recovering an ancient and 'pure' Dravidian language and culture."
