scholars as Janna, Harihara, Rudrabhatta, Raghavanka, Keshiraja and others. An important achievement during this period was the establishment of native metres in literature (the ragale, the tripadi, the sangatya and the shatpadi). Two renowned philosophers who lived during this time, Ramanujacharya and Madhvacharya, influenced the culture of the region. The conversion of the Hoysala King Vishnuvardhana in the early 12th century from Jainism to Vaishnavism was to later prove a setback to Jain literature. In the decades to follow, Jain writers faced competition from the Veerashaivas, to which they responded with rebuttals, and from the 15th century, from the writers of the Vaishnava cadre. These events changed the literary landscape of the Kannada-speaking region forever. One of the earliest Veerashaiva writers who was not part of the Vachana literary tradition, poet Harihara (or Harisvara) came from a family of karnikas (accountants), and worked under the patronage of King Narasimha I. He wrote Girijakalyana in ten sections following the Kalidasa tradition, employing the old Jain champu style, with the story leading to the marriage of Shiva and Parvati. In a deviation from the norm, Harihara avoided glorifying saintly mortals. He is credited with more than 100 poems in ragale metre, called the Nambiyanana ragale (or Shivaganada ragale, 1160) praising the saint Nambiyana and Virupaksha (a form of Hindu god Shiva). For his poetic talent, he has earned the honorific utsava kavi ("poet of exuberance"). Harihara's nephew, Raghavanka, was the first to introduce the shatpadi metre into Kannada literature in his epic Harishchandra Kavya (1200), considered a classic despite occasionally violating strict rules of Kannada grammar. Drawing on his skill as a dramatist, Raghavanka's story of King Harishchandra vividly describes the clash of personalities between sage Vishvamitra and sage Vashisht and between Harishchandra and Vishvamitra. It is believed that this interpretation of the story of Harishchandra is unique to Indian literature. The writing is an original and does not follow any established epic traditions. In addition to Hoysala patronage, Raghavanka was honoured by Kakatiya king Prataparudra I. Rudrabhatta, a Smartha Brahmin (believer of monistic philosophy), was the earliest well-known Brahminical writer, under the patronage of Chandramouli, a minister of King Veera Ballala II. Based on the earlier work of Vishnu Purana, he wrote Jagannatha Vijaya (1180) in the champu style, relating the life of Lord Krishna leading up to his fight with the demon Banasura. In 1209, the Jain scholar and army
