Legend of Lindworm

In the 19th-century tale of "Prince Lindworm" (also "King Lindworm"), from Scandinavian folklore, a "half-man half-snake" lindworm is born, as one of twins, to a queen, who, in an effort to overcome her childless situation, has followed the advice of an old crone, who tells her to eat two onions. She did not peel the first onion, causing the first twin to be a lindworm. The second twin boy is perfect in every way. When he grows up and sets off to find a bride, the lindworm insists that a bride be found for him before his younger brother can marry. Since his bride must love him willingly and none of the chosen maidens do, he eats each new bride they bring him, this creates a slight problem for the kingdom until a shepherd's daughter who spoke to the same crone is brought to marry him. She comes wearing every dress she owns. The lindworm tells her to take off her dress, but she insists he shed a skin for each dress she removes. Eventually he is out of skin and underneath is a handsome prince. Some versions of the story omit the lindworm's twin, and the gender of the soothsayer varies.
