As in earlier centuries, Jain authors wrote about tirthankars (saints), princes and other personages important to the Jain religion. Jain versions of the Hindu epics such as the Ramayana and Bhagavata (tales of Hindu god Krishna) were also written. According to R. Narasimhacharya, a noted scholar on Kannada literature, more Jain writers wrote in Kannada than in any other Dravidian language during the "Augustan age" of Kannada literature, from the earliest known works to the 12th century. The Veerashaiva writers, devotees of the Hindu god Shiva, wrote about his 25 forms in their expositions of Shaivism. Vaishnava authors wrote treatments of the Hindu epics, the Ramayana, the Mahabharata and the Bhagavata. Breaking away from the old Jain tradition of using the "champu" form for writing Kannada literature, Harihara penned poems in the "ragale" metre in "Siva-ganada-ragalegalu" (1160). His nephew Raghavanka established the "shatpadi" tradition by writing a unique version of the story of King Harishchandra in "Harishchandra Kavya" (1200). 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").
