It's the last day of my offsite, so I thought I'd give you something special - monsters. Here's an article by medievalists.net describing the Top Ten Monsters of the Middle Ages, namely:
Grendel + mother
While I agree with most of these I'm not sure Grendel belongs on this list. He's only mentioned in one story, whereas all the others are mentioned by numerous sources. He may be a monster modern audiences think of, but I'm curious how wildly known the story was in the middle ages. I might have picked griffins for the 10th.
Anyway, enjoy. :)
