Vishnu is a Rigvedic deity, but not a prominent one when compared to Indra, Agni and others. Just 5 out of 1028 hymns of the Rigveda are dedicated to Vishnu, although He is mentioned in other hymns. Vishnu is mentioned in the Brahmana layer of text in the Vedas, thereafter his profile rises and over the history of Indian mythology, states Jan Gonda, Vishnu becomes a divinity of the highest rank, one equivalent to the Supreme Being.
