We may never have heard of a certain slave from a household in the Greek city of Phrygia if not for his charming use of morals in folktales, but Aesop has made a name for himself. Dr. Harvey presents several of his tales, including “The Tortoise and the Hare,” “Androcles and the Lion,” “The Stone in the Road,” “The Fox and the Wolf,” and “Belling the Cat.” She also shares Kipling’s “Camel Poem” and “How the Hamster Got his Tail,” a Kenyan story about why hamsters have small tails.
