In the spring of 2003, I spent three weeks in the city of Chennai, formerly known as Madras, located in Southern India. Each morning, walking before the heat of the day, I was amazed to see intricate knot work patterns drawn out free hand with flour in front of the driveways and gates of homes. These artistic scrolls, I was told by an Indian friend, were offerings to local gods, and were part of a tradition that stretched back into the ancient past.I have seen knot patterns in my travels through.
