PORTLAND, Maine—A bargain hunter who went to an estate sale in Maine to find a KitchenAid mixer, a bookshelf or vintage clothing walked away with a 700-year-old treasure.
Instead of a kitchen appliance, Will Sideri stumbled upon a framed document hanging on a wall. It had elaborate script in Latin, along with musical notes and gold flourishes. A sticker said 1285 AD. Based on what he’d seen in a manuscripts class at Colby College, the document looked downright medieval.
