This is a ramble. Sorry.
The medieval period is not just attractive to geeks, and its attractiveness did not begin with Tolkien, or with Howard. There are at least three older sources that have to be considered:
- The Arthurian legends, which started rolling with Geoffrey of Monmouth, and kicked into high gear with Malory’s “Le Morte d’Arthur;”
- The perennial popularity of Chaucer, especially, of course, the “Canterbury Tales;” and
- The phenomenal success of Sir Walter Scott’s novels.
I have googled in vain for accounts of 12th and 14th century geekiness, but Mark Twain has quite a bit to say in Life on the Mississippi (none of it flattering) about the popularity of Scott in the south. He makes the plantation owners out as geeks of the first magnitude. Also, reading his description of Mardi Gras, I came away thinking, “Hmm, Mardi Gras is a frickin’ a RenFest.”
I’m not all that geeky myself, at least in this regard, but I did have quite a fascination with medieval stuff from having seen “Ivanhoe” and “Knights of the Round Table” as a kid. The neighborhood kids ran around with lances (willow branches), wooden swords, and shields, and whacked the hell out of each other with them. And these movies were 10 years old by the time we saw them.
So I think that the highly-distorted literary depictions of medieval times has grabbed the popular imagination for centuries. We discard all the nasty realities of that era, and are left with something that is primal, exciting, and morally unambiguous. Swords are fun. Magic swords are even more fun. So are really, really bad guys and really, really good guys (hey, that’s me!). Add in elves, gnomes, fairies, dryads, naiads, castles, monsters, demons, secret places, and magic, and you’ve got a world that’s really worth living in.
The only difference between geeks and non-geeks with regard to this stuff is that the geek is a little more able to suspend disbelief while indulging in the fantasy. They’re all at their desks bright and early Monday morning with the rest of us, though.
