Fantasy maps increased in number during the 20th century due to the rise of science fiction and fantasy writing, and the birth of television and video games.
Many of them are products of the wildest imaginations, and are immersive places of escapism. Yet all of them retain vestiges of the ‘real’ world in which they were created—whether because of a particular feature illustrated in it, the way in which it has been drawn, or even the ‘real-world’ contexts which inspired it.
Harper’s examples aren’t what someone well-versed in fantasy fiction would expect: they include Milne and Tolkien, but also Sleigh’s 1918 map of Fairyland (above), San Serriffe, and other maps of the unreal from outside genre fiction. (A reminder that fantasy map does not only mean map accompanying a secondary-world fantasy novel in the Tolkien tradition.)
