The Seven Ravens (Story Time, Episode 55)

A peasant has seven sons and no daughter. Finally a daughter is born, but is sickly. The father sends his sons to fetch water for her, in the German version to be baptized, in the Greek version to take water from a healing spring. In their haste, they drop the jug in the well. When they do not return, their father thinks that they have gone off to play and curses them and so they turn into ravens.
