work Vishnu Purana, he wrote Jagannatha Vijaya in the Champu style relating the life of Krishna leading up to his fight with the demon Banasura. Harihara, (also known as Harisvara) a Lingayati writer and the patron of King Narasimha I, wrote the Girijakalyana in the old Jain Champu style which describes the marriage of Shiva and Parvati in ten sections. He was one of the earliest Virashaiva writers who was not part of the vachana literary tradition. He came from a family of accountants (Karanikas) from Halebidu and spent many years in Hampi writing more than one hundred ragales (poems in blank verse) in praise of Virupaksha (a form of Shiva). Raghavanka was the first to introduce the Shatpadi metre into Kannada literature in his Harishchandra kavya which is considered a classic even though it occasionally violates strict rules of Kannada grammar. In Sanskrit, Madhvacharya wrote the Rigbhshya on the Brahma Sutras (a logical explanation of Hindu scriptures, the Vedas) as well as many polemical works rebutting the doctrines of other schools. He relied more on the Puranas than the Vedas for logical proof of his philosophy. Another famous writing was Rudraprshnabhashya by Vidyatirtha. Architecture The modern interest in the Hoysalas is due to their patronage of art and architecture rather than their military conquests. The brisk temple building throughout the kingdom was accomplished despite constant threats from the Pandyas to the south and the Seunas Yadavas to the north. Their architectural style, an offshoot of the Western Chalukya style, shows distinct Dravidian influences. The Hoysala architecture style is described as Karnata Dravida as distinguished from the traditional Dravida, and is considered an independent architectural tradition with many unique features. A feature of Hoysala temple architecture is its attention to exquisite detail and skilled craftsmanship. The tower over the temple shrine (vimana) is delicately finished with intricate carvings, showing attention to the ornate and elaborately detailed rather than to a tower form and height. The stellate design of the base of the shrine with its rhythmic projections and recesses is carried through the tower in an orderly succession of decorated tiers. Hoysala temple sculpture replicates this emphasis on delicacy and craftsmanship in its focus on depicting feminine beauty, grace and physique. The Hoysala artists achieved this with the use of Soapstone (Chloritic schist), a soft stone as basic building and sculptural material. The Chennakesava Temple at Belur (1117), the Hoysaleswara
