Durgasimha, the "Sandhi Vigrahi" (minister of war and peace) of King Jayasimha II wrote the well-known "Panchatantra" ("The five stratagems", 1031) in "champu" style, basing it on Gunadhya's Paishachi language original "Brihatkatha". This fable is the first adaptation of the original into a vernacular language of India. Containing sixty fables in all, thirteen of which are original, each is summarised by an ethical moral based on a Jain tenet. Durgasimha also authored the "Karnataka Banachatantra", the earliest available commentary in the Kannada language, giving a brief commentary on all the Sanskrit verses he quoted in the "Panchatantra". Around this time, Jayakirti (c. 1000–1050), a Kannada language theorist, who considered the rules of prosody to be the same for Sanskrit and Kannada, wrote the "Chandonusasana"
