Which leads us to ask the question: who, or what, is the namesake of this autumn tradition? Who are jack-o’-lanterns named for? Both the tradition of carving a pumpkin and the name jack-o’-lantern are rooted in Irish lore and date back hundreds of years. In the mid-1800s, young boys used hollowed-out and lit-up root vegetables to spook people. Irish legend has it that this use of jack-o’-lantern was named after a fellow named Stingy Jack. Stingy Jack thought he had tricked the devil, but the devil had the last laugh, condemning Jack to an eternity of wandering the planet with only an ember of hellfire for light. Jack’s lanterns were carved out of potatoes, turnips, and the vegetables, in Scotland and Ireland, while beets were used in England. When immigrants brought this custom to North America, pumpkins eventually became the vegetable of choice. But the name jack has been a general term for a boy since the 1500s and for this reason, it found its way into many childhood songs and rhymes. For this reason, the British can also claim ownership to one of the original uses of the phrase jack-o’-lantern. In the 17th century, the term referred to a night watchman, a man who literally carried a lantern. Unlock a new world of learning!
