Matsya

Matsya (Sanskrit: मत्स्य, lit. 'fish') is the fish avatar of the Hindu god Vishnu. Often described as the first of Vishnu's ten primary avatars, Matsya is described to have rescued the first man, Manu, from a great deluge. Matsya may be depicted as a giant fish, often golden in color, or anthropomorphically with the torso of Vishnu connected to the rear half of a fish.

The earliest account of Matsya is found in the Shatapatha Brahmana, where Matsya is not associated with any particular deity. The fish-saviour later merges with the identity of Brahma in post-Vedic era, and still later, becomes regarded with Vishnu. The legends associated with Matsya expand, evolve, and vary in Hindu texts. These legends have embedded symbolism, where a small fish with Manu's protection grows to become a big fish, and the fish saves the man who would be the progenitor of the next race of mankind. In later versions, Matsya slays a demon named Hayagriva who steals the Vedas, and thus is lauded as the saviour of the scriptures.

The tale is ascribed with the motif of flood myths, common across cultures.
