Gadag immediately brings to mind the name of Naranappa, popularly known as Kumara Vyasa, the author of Karnata Bharata Kathamanjari. It is the classic Mahabharata in Kannada. Naranappa was born in the nearby village of Koliwada. He composed his work sitting before Lord Veera Narayana, his chosen deity. The temples of Veera Narayana and Trikuteshwara [1] are places of religious and historic importance. The blind singer Ganayogi Panchakshari Gawayi belonged to Gadag. His music school (Veereshwara Punyashrama) [[2]] is famous. The Tontadarya Matha of the Veerashaiva sect of Hinduism is engaged in many educational and literary activities in and around Gadag.
