In aboriginal Australian mythology, the Yurlungur is a great copper snake that is said to bring the rains and thus incite the renewal of life. It is commonly known as the Rainbow Serpent or the Rainbow Snake, because the water where it lives shines like a rainbow. It was believed that if colored light was seen inside a well (likely caused by light reflection) then the Yurlungur was within.
In one story of the Yurlungur, he was awoken from a deep sleep by the smell of one of the Wawalag sisters' menstrual blood. Aroused by the smell of the blood, Yurlungur swallowed the Wawalag sisters whole, however it was later forced to regurgitate them both. The act of the serpent regurgitating them is used in Aboriginal ceremonies to symbolize a boy entering manhood.
"Origin: Australia. A snake god known as the Rainbow Serpent. It is an Australian Aboriginal god with great powers. When angered, it can cause floods and disease. It is also a god of fertility."
