The Ratnavali or the 'Jewel Necklace' is a drama of the Natika type by Sriharsa. Theme is the marriage, through various obstacles and at the clever intervention of the minister Yaugandharayana, of king Udayana and Ratnavali, daughter of the king of Ceylon. A brief but sufficiently exhaustive commentary in sanskrit has been written, as there was no suitable ancient commentary available on this play. Another feature of this edition is the introduction wherein all that has been known of the author and the play has been put together for ready reference and and systematic study.
