The earliest mention of Kathak as an art form is found in the Arjuna-Vanavasa chapter of the Aadi-Parva of Mahabharata. In its initial phase, Kathak is regarded to have been a mimetic representation of Puranic literature accompanied with dance. Kathakas were Granthikas reciting stories related to Vishnu. When Krishna was identified with Vishnu, Granthikas began narrating Krishna-based stories. During this time, a rich musical theater form had grown out of the rich Krishna theater tradition of Mathura region. It is believed that Katha-Vachan, the earliest form of Kathak was exclusively based on Krishna’s legend.

It is said that when Krishna danced his divine dance on the hood of the defeated serpent Kaliya, various mnemonic sounds emanated from Krishna’s feet, which formed the building blocks of Kathak. Krishna is also known as “Natwar”, hence these sounds came to be known as Natwari.
