 Sisumayana introduced the "sangatya" metre in his "Anjanacharita" and "Tripuradahana" (1235).However, some scholars continued to employ Sanskritic genres such as "champu" ("Ramachandra Charitapurana"), "shataka" (100 verse compositions, "Pampa sataka") and "ashtaka" (eight line verse compositions, "Mudige ashtaka").The exact beginnings of the haridasa movement in the Kannada-speaking region have been disputed.
