Shri G. Venu , a disciple of Ammannur Madhavachakyar, has in his book, developed an innovative and illustrative notational system for the eyes, eyebrows, facial muscles, torso and hand gestures that form the unique and elaborate vocabulary of Kutiyattam.  The listing of Kutiyattam  on the UNESCO Masterpieces of Oral and Intangible Heritage of Humanity in 2001 served to confirm that the international community recognizes Kutiyattam as the best surviving example of Sanskrit theatre in the world and an outstanding example of human creativity.  NCF through this project assisted in documenting a rare and dying oral tradition and in its preservation.
