In the myth of Osiris, after he has been killed and cut into pieces by his brother Seth, his phallus falls in the Nile and is devoured by a fish. Implored by Isis, it releases the phallus so that she can conceive her son Horus. The fish, a symbol of fertility, was named oxyrhynchus because of the site where it was worshipped in Middle Egypt.
