In the words of David Smith, “there is no Sanskrit poet more interesting than Bāṇa, none more original, none greater, and his prose poem “Princess Kādambarī” is his supreme achievement. Always held in India to be the best prose poem, Bāṇa’s Kādambarī is a masterpiece of classical Sanskrit literature, unrivaled in richness and depth. The late Professor Willem Bollée (1927–2020) has prepared an index of words and notions of Bāṇa’s difficult and unique romance Kādambarī with a view to unclosing the wealth of cultural information contained in this second work of genius of Bāṇa. Professor Bollée has released the present edition for printing. It is the last monograph from his untiring pen.
