Versions of the flood myth have been told by the Mayans, the Greeks, the Native Americans, the Africans, the Celts, The summer , The akkad , Australian Aborigines, the Chinese….the list goes on.

But the great flood of manu and matsya is very popular.

In the Hindu myth (first appearing in the Shatapatha Brahmana and later in the Puranas & the Mahabharata), Manu helps save a small fish, He then raises the fish, until it’s almost the size of the entire ocean.

The fish then transforms into Vishnu and saves him and  seven great sages from the deluge. Manu then marries and re-populates  the earth 

The Sanskrit word for ‘human’ is mānava, which literally means ‘Children of Manu’

The earliest accounts of Matsya as a fish-saviour equates him with the Vedic deity Prajapati. The fish-savior later merges with the identity of Brahma in post-Vedic era, and still later as an avatar of 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 earthly existence.

It makes no mention of Vishnu, and instead identifies the fish with Prajapati-Brahma.The central characters of this legend are the fish (Matsya) and Manu. The character Manu is presented as the legislator and the ancestor king of meena's .

When the flood came, Manu used a rope to tie his boat to a large horn growing out of the fish. Pulling the ship through the rough waters.
