Eingana

In Aboriginal mythology, Eingana is a creator goddess and the mother of all water, animals and humanity. She is a snake goddess of death who lives in the Dream time. She has no vagina; she simply grew in size and, unable to give birth to the life inside her, had the god Barraiya open a hole with a spear near her anus, so that labor could commence. Eingana holds a sinew that is attached to all living things; if she lets go, the organism dies.
