austin Kleon has a nifty post about maps of fictional worlds ... primarily made by the authors themselves.
My undergrad thesis argued that world-building wasn’t just for fantasy and sci-fi writers—every tale has a setting, every tale creates a world in the reader’s mind—and it explored ways that drawing that world (visual thinking!) can lead to better fiction.
Some of my favorite “lit’ry” books are accompanied by maps.
I've talked before on this subject and have nothing new to say at this time, but check out the post for images and links to other maps, especially in Kleon's previous posts, and in the comments section.
