Passage: The Kannada poets and scholars of the empire produced important writings supporting the Vaishnava Bhakti movement heralded by the Haridasas (devotees of Vishnu), Brahminical and Veerashaiva (Lingayatism) literature. The Haridasa poets celebrated their devotion through songs called Devaranama (lyrical poems) in the native meters of Sangatya (quatrain), Suladi (beat based), Ugabhoga (melody based) and Mundige (cryptic). Their inspirations were the teachings of Madhvacharya and Vyasatirtha. Purandaradasa and Kanakadasa are considered the foremost among many Dasas (devotees) by virtue of their immense contribution. Kumara Vyasa, the most notable of Brahmin scholars wrote Gadugina Bharata, a translation of the epic Mahabharata. This work marks a transition of Kannada literature from old Kannada to modern Kannada. Chamarasa was a famous Veerashaiva scholar and poet who had many debates with Vaishnava scholars in the court of Devaraya II. His Prabhulinga Leele, later translated into Telugu and Tamil, was a eulogy of Saint Allama Prabhu (the saint was considered an incarnation of Lord Ganapathi while Parvati took the form of a princess of Banavasi).At this peak of Telugu literature, the most famous writing in the Prabandha style was Manucharitamu. King Krishnadevaraya was an accomplished Telugu scholar and wrote the celebrated Amuktamalyada. Amuktamalyada ("One who wears and gives away garlands") narrates the story of the wedding of the god Vishnu to Andal, the Tamil Alvar saint poet and the daughter of Periyalvar at Srirangam. In his court were eight famous scholars regarded as the pillars (Ashtadiggajas) of the literary assembly. The most famous among them were Allasani Peddana who held the honorific Andhrakavitapitamaha (lit, "father of Telugu poetry") and Tenali Ramakrishna, the court jester who authored several notable works. The other six poets were Nandi Thimmana (Mukku Timmana), Ayyalaraju Ramabhadra, Madayyagari Mallana, Bhattu Murthi (Ramaraja Bhushana), Pingali Surana, and Dhurjati. This was the age of Srinatha, the greatest of all Telugu poets of the time. He wrote books such as Marutratcharitamu and Salivahana-sapta-sati. He was patronised by King Devaraya II and enjoyed the same status as important ministers in the court.Though much of the Tamil literature from this period came from Tamil speaking regions ruled by the feudatory Pandya who gave particular attention on the cultivation of Tamil literature, some poets were patronised by the Vijayanagara kings. Svarupananda Desikar wrote an anthology of 2824 verses, Sivaprakasap-perundirattu, on the Advaita philosophy. His pupil the ascetic, Tattuvarayar, wrote a shorter anthology, Kurundirattu, that contained about half the number of verses. Krishnadevaraya patronised the Tamil Vaishnava poet Haridasa whose Irusamaya Vilakkam was an exposition of the two Hindu systems, Vaishnava and Shaiva, with a preference for the former.Notable among secular writings on music and medicine were Vidyaranya's Sangitsara, Praudha Raya's Ratiratnapradipika, Sayana's Ayurveda Sudhanidhi and Lakshmana Pandita's Vaidyarajavallabham. The Kerala school of astronomy and mathematics flourished during this period under such well known scholars as Madhava (c. 1340–1425) who made important contributions to Trigonometery and Calculus, and Nilakantha Somayaji (c. 1444–1545) who postulated on the orbitals of planets.
