Commentaries on literary texts, be they Kāvyas or Nāṭyas, are a prolific though still much understudied genre in South Asia. The stress on the literary text as the achieved and circumscribed “work of art” has undermined studies on the reception history, transmission, and composing and staging of literary texts, where the poem or drama in its entirety is not always the main unit to be considered. Along these lines, literary commentaries are crucial for understanding the relation between theoretical prescriptions and compositional/performative practices, as they often put these two dimensions of literature (the theoretical and the practical) into dialogue. Moreover, a host of knowledge systems (nāṭyaśāstra, alaṃkāraśāstra, vyākaraṇa, mīmāṃsā, etc.), along with their philosophical insights, technical vocabulary, and hermeneutical techniques, are employed, combined, and creatively refunctionalized in literary commentaries, which therefore represent a liminal genre of śāstra that crosses the seemingly well-established boundaries among disciplines and offers to the modern scholar a unique window into the intellectual life of premodern South Asia.
