While Pāṇini's work is purely grammatical and lexicographic, cultural and geographical inferences can be drawn from the vocabulary he uses in example… - Panini

The medicine of Sushruta is considerably older than the ninth century; and the grammar of Panini probably precedes Christianity.

In the fifteenth century Rāmachandra, in his Prakriyā-kaumudī, or "Moonlight of Method," endeavoured to make Pāṇini's grammar easier by a more practical arrangement of its matter. Bhaṭṭoji's Siddhānta-kaumudī (seventeenth century) has a similar aim; an abridgment of this work, the Laghu-kaumudī, by Varadarāja is commonly used as an introduction to the native system of grammar. Among non-Pāṇinean grammarians may be mentioned Chandra (about 600 A.D.), the pseudo-Çākaṭāyana (later than the Kāçikā), and, the most important, Hemachandra (12th century), author of a Prākrit grammar.

Classical Sanskrit theatre flourished during the first nine centuries CE. Aphorisms on acting appear in the writings of Panini, the Sanskrit grammarian of the 5th century BCE, and references to actors, dancers, mummers, theatrical companies, and academies are found in Kautilya’s book on statesmanship, the Artha-shastra (4th century BCE).
