 In an engraving from 1856, the painter Edvard Lehmann, who was also a close friend of the Bournonville family, portrayed the spellbound Junker Ove encircled by the hovering, luminous elves.Ove is briefly imprisoned in this state, but fortunately the beautiful Hilda comes to his rescue with water from a healing spring.Even though she has grown up among trolls inside the hill, we know that she is really a changeling, swapped as a baby with the temperamental Birthe, who is the real troll child.
