The Pagan Fish is yet another symbol that has been plagiarised by Christians.
The 'fish symbol' is today instantly recognised as a Christian symbol but this symbol was in use by Pagans for many generations before Christianity.
Ask any neo-pagan and they will explain the most common interpretation is its derivation from a simplified image of a woman's womb or vagina. The fish symbol was often drawn by overlapping two thin crescent moons, signifying a woman's monthly cycle. (See also Lunate Cross.)
In Babylonian mythology, a fish pushed a giant egg out of the river Euphrates, and from this egg emerged the mermaid and fertility goddess of the seas, Atargatis. The son of Atargatis was named Ichthys.
There are a few other Pagan goddesses and gods that manifest themselves as dolphin, fish or other sea creature, and most seem to be connected with sexuality. The oval outline of a fish was compared to the shape of the womb, and both 'fish' and 'womb' homophonously shared the ancient Greek word delphos. (See also Dolphin Cross.)
