Odissi dance and music are classical forms. Odissi has a tradition of 2,000 years, and finds mention in the Natyashastra of Bharatamuni, possibly written circa 200 BCE. However, the dance form nearly became extinct during the British period, only to be revived after India's independence by a few proponents, such as Guru Deba Prasad Das, Guru Pankaj Charan Das, Guru Raghunath Dutta and Kelucharan Mohapatra. Odissi classical dance is about the divine love of Krishna and his consort Radha, mostly drawn from compositions by the notable Oriya poet Jayadeva, who lived in the 12th century CE.
