An ancient treatise on Indian communication arts, the Natya Sastra, was written by

The ancient treatise on Indian communication arts, the Natya Sastra, was composed by Bharata Muni.

It is a foundational text on dramaturgy, dance, music, gesture and the whole grammar of performance and expression.

Panini is remembered for the Ashtadhyayi, a landmark work on Sanskrit grammar, not on dramatic arts.

Prabhakara is associated with a school of Mimamsa philosophy dealing with ritual and interpretation.

Mandana Mishra was a Mimamsa scholar known for philosophical debate, not for the theatre treatise.

Bharata Muni's work remains the classical Indian source on communicative and performative technique.
