Kanti (1108), known for her wit and humour, was one of the earliest female poets of the Kannada language and a contemporary of Nagachandra, with whom she indulged in debates and repartees. Rajaditya, a native of either Puvinabage or Raibhag (the modern Belgaum district), was in the Hoysala court during the days of King Veera Ballala I and King Vishnuvardhana. He wrote in easy verse on arithmetic and other mathematical topics and is credited with three of the earliest writings on mathematics in the Kannada language: "Vyavaharaganita", "Kshetraganita" and "Lilavati". Udayaditya, a Chola prince, authored a piece on rhetoric called "Udayadityalankara" (1150). It was based on Dandin's Sanskrit "Kavyadarsa".
