The name jack-o’-lantern can be traced back to the Irish legend of Stingy Jack,  a greedy, gambling, hard-drinking old farmer. He tricked the devil into climbing a tree and trapped him by carving a cross into the tree trunk. In revenge, the devil placed a curse on Jack, condemning him to forever wander the earth at night with the only light he had: a candle inside of a hollowed turnip.
I’d never known the history behind the name before, that’s actually pretty cool. I guess the devil couldn’t fly back then?
