Balarama is an ancient deity, a prominent one by the epics era of Indian history as evidenced by archeological and numismatic evidence. His iconography appears with Nāga (many-headed serpent), a plough and other farm artifacts such as a watering pot, possibly indicating his origins in a bucolic, agricultural culture. Balarama's legend appears in many Parva (books) of the Mahabharata. The Book Three (Vana Parva) states about Krishna and him that Balarama is an avatar of Vishnu, while Krishna is the source of all avatars and existence. In some art works of the Vijayanagara Empire, temples of Gujarat and elsewhere, for example, Baladeva is the eighth avatar of Vishnu, prior to the Buddha (Buddhism) or Arihant (Jainism).
