Herps in Society and Culture: Heqet - Egyptian goddess of fertility

Heqet is an Egyptian goddess of fertility and childbirth. She is depicted either as a frog or a woman with the head of a frog.

With the annual flooding of the Nile, the Egyptians would see many frogs and tadpoles. The frog was a symbol of fruitfulness, coming of new life, and fertility to the ancient Egyptians. Many women wore amulets of Heqet around their necks during childbirth to ward off any evil sprits (pictured below: second amulet from left on the top row.)

I find the use of frogs as a symbol of birth, fruitfulness, and fertility very appropriate as frogs have such a complex life cycle and symbolize rebirth through metamorphosis.
