Memory is hazy still I remember the idol is a river personified, Kaveri perhaps. I liked this sculpture for the curved crocodile and the inexplicable expression of the statue unlike other mythological faces where benevolence is the common expression.
I sketched this not from the idol directly but from its photograph .
At that time I had a Kodak K-10 camera and the image I took from it helped little in recreating the idol . So, though the sketch is as near to the grainy image I clicked, the detailing is mostly imagination.
