 The "tripadi" metre, one of the oldest in the Kannada language (Kappe Arabhatta inscription of 700), which was used by Akka Mahadevi ("Yoganna trividhi", 1160), was popularised in the 16th century by the mendicant poet Sarvajna.Even Jain writers, who had dominated courtly literature throughout the classical period with their Sanskritic "champu" style, began to use native metres.Among them, Ratnakaravarni is famous for successfully integrating an element of worldly pleasure into asceticism and for treating the topic of eroticism with discretion in a religious epic written in the native "sangatya" metre (a metre initiated by Hoysala poet Sisumayana), his "magnum opus", the "Bharatadesa Vaibhava" (c. 1557).
