Continuing south of Puducherry along the Coromandel coast, you enter the flat landscape of the Kaveri (aka Cauvery) Delta, a watery world of canals, dams, dykes and rivulets that has been intensively farmed since ancient times. Just 160km in diameter, it forms the verdant rice-bowl core of Tamil Nadu, crossed by more than thirty major rivers and countless streams. The largest of them, the River Kaveri, known in Tamil as Ponni, “The Lady of Gold” (a form of the Mother Goddess), is revered as a conduit of liquid shakti, the primordial female energy that nurtures the millions of farmers who live on her banks and tributaries. The landscape here is one endless swathe of green paddy fields, dotted with palm trees and little villages of thatched roofs and market stalls; it comes as a rude shock to land up in the hot and chaotic towns.
This mighty delta formed the very heartland of the Chola empire, which reached its apogee between the ninth and thirteenth centuries, an era often compared to classical Greece and Renaissance Italy both for its cultural richness and the sheer scale and profusion of its architectural creations. Much as the Cholas originally intended, every visitor is immediately in awe of their huge temples, not only at cities such as Chidambaram, Kumbakonam and Thanjavur, but also out in the countryside at places like Gangaikondacholapuram, where the magnificent temple is all that remains of a once-great city. Exploring the area for a few days will bring you into contact with the more delicate side of Chola artistic expression, such as the magnificent bronzes of Thanjavur.
