Fish.
Fish are in many places regarded as sacred. The salmon of knowledge appears in the Celtic folk-lore.150 The sacred speckled trout are found in many Irish wells, and the same idea prevails in many parts of Europe.151 We find the fish figuring in the Hindu myth of the Creation. Manu, while he was bathing, found a fish in the water, which said, “I will save thee from the flood which shall destroy the world.” The fish grew and was about to go to the ocean, when he directed Manu to build a boat. When the deluge came, the fish dragged the boat by his horn to a place of safety. The myth appears in other forms, more or less akin to the Hebrew story based on Babylonian tradition.
There are many places in India where fish are protected, such as those at Kota and in the Mahânadî river, the Betwa at Bhilsa, Hardwâr, Mathura, Mirzapur, Benares, Nepâl, and in Afghanistân.152 In the Sâraswata pool in the Himâlaya lived the sacred fish called Mrikunda; they are fed on the fourteenth of the light half of each month, and oblations are offered for the repose of the Manes of deceased relations.153 It is a common custom among pious Hindus to feed fish at sacred places with a lâkh or more of little balls of flour wrapped up in Bhojpatra or birch bark or paper with the name of Râma written upon it. Their eating the name of the deity ensures their salvation, and thus confers religious merit on the giver. The fish is the vehicle of Khwâja Khizr, the water god, and hence has become a sort of totem of the Shiah Musalmâns and the crest of the late royal family of Oudh. Pictures of fish are constantly drawn on the walls of houses as a charm against demoniacal influence.
