The Rati-Ratna-Pradipika, a minor text on erotica written in South India by a member of the Wadiyar royal family, is translated and annotated here with scholarly apparatus and academic understanding of sexual mechanics by a member of the Wadiyar royal family 350 years later. While the original text is incomplete, the treatment of the text by Sivapriyananda will make it a welcome contribution to India's very popular ancient erotica. Sivapriyananda has made a distinct departure from the traditional presentations of erotic textual and visual material. The art work accompanying the text is by 'Ganjifa' Raghupati Bhatta, perhaps India's foremost contemporary erotic artist and complements both the ancient text and the very modern annotations to the text.
