Hasta Karaṇas -
Nṛtyavinōda of Mānasôllāsa - Language: Sanskrit
This a great text for everything. It's written in the Western Chalukyan dynasty which is in modern day Karnataka and Andhra Pradesh. This a truly broad and yet detailed text covering a number of elements of life at this time. One volume of this set of tomes is the Nṛtyavinōda. It returns to the same type of format of the Natya Sastra in that lists sets of movements of each part of the body with descriptions of how to execute them and what they mean.
