 Keshiraja was a notable writer and grammarian of the 13th century . He came from a family of famous poet @-@ writers . Although five of Keshiraja 's writings are not traceable , his most enduring work on Kannada grammar , Shabdamanidarpana ( " Mirror of Word Jewels " , 1260 ) , is available and testifies to his scholarly acumen and literary taste . True to his wish that his writing on grammar should " last as long as the sun , the moon , the oceans and the Meru mountain lasted " , Shabdamanidarpana is popular even today and is considered a standard authority on old Kannada grammar . It is prescribed as a textbook for students of graduate and post @-@ graduate studies in the Kannada language . Although Keshiraja followed the model of Sanskrit grammar ( of the Katantra school ) and that of earlier writings on Kannada grammar ( by King Amoghavarsha I of the 9th century and grammarian Nagavarma II of 1145 ) , his work has originality . Keshiraja 's lost writings are Cholapalaka Charitam , Sri Chitramale , Shubhadraharana , Prabodhachandra and Kiratam ( or Kiratarjuniyam ) .
