It's amazing to me that so much medieval poetry has survived into the present day. After all, most people at that time weren't even literate! I know some of these poems survived as part of oral traditions, but I still think it's pretty neat.
I also wonder how much medieval poetry has been lost since it was never written down. I imagine people of that time didn't just commit every poem to paper, and instead decided which ones were good enough to preserve. I wonder if we're missing out on any masterpieces that were lost because they were never written down.
