Hasta Karaṇas -
Nartananirṇaya - Language: Sanskrit
The author is thought to be a South Indian, who migrated between courts, eventually writing this text for the Emperor Akbar. The text talks about drama, music, and dance - much like the Natya Sastra, but includes more modern concepts. Bose describes it as the missing link between ancient and current classical dance.
