The Wisconsin cartographer who mapped Tolkien's fantasy world

Atlas of Middle-earth is a truly monumental feat.

I think the article writer misses how much of it is really about The Silmarillion, rather than about Lord of the Rings. Tolkien put a lot of work into First Age geography, an entire (interminable, excruciating) chapter of The Silmarillion. Very little of it would be familiar to viewers of the films, and a lot of it opaque even to readers just of LotR.

My favorite parts of the Silmarillion were the ones where I learned the back story of the world: the Valaquenta, the Ainulindalë, and Of the Rings of Power and the Third Age. I don't have my copy here, but if I recall correctly that last section starts with Of old there was Sauron the Maia.... That's the stuff I wanted to know.

I was also impressed by Tolkien's creation myth. I'm not really familiar with the various religions or mythologies, whether invented by a single author or developed over time by pre-scientific societies, but his is the only one I know of where the creation was based on music.
