While folklore, fairytales, and fantasy vary in definition, they possess the common elements of supernatural beings, strange locales, and imaginative content. Folk tales, originally intended for all ages, were meant to convey lessons about moral behavior and group values; good was rewarded and evil punished. In contemporary literature, high fantasy and science fiction repeat many of the same folklore themes. Plots are often based on myths and legends, the main character exemplifies great virtue, and evil must be conquered, often through the use of magical devices. Authors who represent this type of fantasy writing include Alexander Prydain in his quintette about Taran, Susan Cooper in the five books of "The Dark Is Rising" series, C. S. Lewis in the seven books about Narnia, and J.R.R. Tolkien in the Hobbit tales. Current examples of folk themes in science fiction appear in the motion picture "Star Wars" and the "Star Trek" television series. (MAI)
