A model of heroic fortitude and pious resignation. She was a princess betrothed to Herwig, but the King of Norway carried her off captive. As she would not marry him, he put her to all sorts of menial work, such as washing the dirty linen. One day her brother and lover appeared on the scene, and at the end she married Herwig, pardoned the naughty king, and all went merry as a marriage bell. (A North-Saxon poem.)
