"The Little Lame Prince and his Travelling Cloak" (often published under its shorter title The Little Lame Prince) is a story for children written by Dinah Maria Mulock Craik and first published in 1875.[1] In the story, the young Prince Dolor, whose legs are paralysed due to a childhood trauma, is exiled to a tower in a wasteland. As he grows older, a fairy godmother provides a magical traveling cloak so he can see, but not touch, the world. He uses this cloak to go on various adventures, and develops great wisdom and empathy in the process. Finally he becomes a wise and compassionate ruler of his own land. (Excerpt from Wikipedia)
