Multiple independent timeframes, in which time passes at different rates, have long been a feature of fairy tales. Fantasy writers such as J. R. R. Tolkien and C. S. Lewis have made use of these and other multiple time dimensions, such as those proposed by Dunne, in some of their most well-known stories. It has been argued that Tolkien borrowed his ideas for Lórien time in The Lord of the Rings, and that Lewis adopted them for his Chronicles of Narnia.
