What continues to fascinate me is why these misconceptions about the Middle Ages persist. It will be an essay, one day, but even just glancing through the items Aldarion lists, it's easy to see they are all about how medieval people were less than ourselves--worse in just about every way. There's a whole other set of misconceptions derived from the romanticization of the Middle Ages in the 19thc. Separate essay.
I've said this elsewhere, but I'll repeat it: when people complain about the Middle Ages being overused in fantasy, they're really only talking about a very small sliver of a thousand years and an entire continent. Most of medieval Europe remains a mine with plenty of ore left in it.
Skip, can you also do an essay on things people consider to be Medieval that are actually Renaissance/Reformation? I feel like there's a pretty big list there.
