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.

It's a really great analogy for how God can allow his creations free will without it messing up His Work. Melkor uses his free will to try and make his own "music" discordant from Eru's but Eru just incorporates it into His music and makes the whole song better.
