"The Woman Who Had No Shadow" is a Scandinavian fairy tale, included by Sven Grundtvig in Gamle danske Minder i Folkemunde and Ella Ohlson in Sagor från Ångermanland.
[1] A woman, wishing to have no children, threw rocks into a well at a witch's direction.
Her husband, the parson, demanded to know why and threw her out, saying that their slate roof would blossom with flowers before she was forgiven.
One day, a beggar woman sought refuge there; she died in the night, the parson recognized her as his wife, and the housekeeper called him out to see how the roof had bloomed with flowers.
[1] Die Frau ohne Schatten by Hugo von Hofmannsthal and Richard Strauss is loosely based on this tale.
