A quirky medieval sermon—filled with what we'd now call "memes" and riddled with spelling errors—might have cracked a centuries-old puzzle in Chaucer’s Canterbury Tales. Researchers think this overlooked text could finally decode a baffling line that’s stumped scholars for 600 years.

Editor’s Note: It’s not every day a 14th-century mystery gets untangled, especially one involving a literary giant like Chaucer. This discovery shows how even the smallest historical details—like a meme-filled sermon—can shed light on cultural inside jokes or errors that traveled across centuries. For book nerds and history buffs, it’s a reminder that the past is way weirder (and more relatable) than we think.
