What is "kiratarjuniya"

Kirātārjunīya (, Of Arjuna and the Kirāta) is a Sanskrit kavya by Bhāravi, written in the 6th century or earlier. It is an epic poem in eighteen cantos describing the combat between Arjuna and lord Shiva at Indrakeeladri hills in present-day Vijayawada in the guise of a kirāta or mountain-dwelling hunter. Along with the Naiṣadhacarita and the Shishupala Vadha, it is one of the larger three of the six Sanskrit mahakavyas, or great epics. It is noted among Sanskrit critics both for its gravity or depth of meaning, and for its forceful and sometimes playful expression. This includes a canto set aside for demonstrating linguistic feats, similar to constrained writing. Later works of epic poetry followed the model of the Kirātārjunīya.
