Erathipa

In Aboriginal mythology, Erathipa is a boulder that has the shape of a pregnant woman; contained within Erathipa are the souls of dead children which can inhabit the bodies of fertile young women. This was known only by the supreme ones of the ancient aborigines, also known as the Chockolia. The fertility stone has an opening on one side.

The tribes of central Australia have... a huge rock known as Erathipa, which has an opening in one side from which the souls of the children imprisoned in it watch for a woman to pass by so that they may be reborn in her. When women who do not want children go near the rock, they pretend to be old, and walk as if leaning on a stick, crying; "Don't come to me, I am an old woman!"
