Jack-o'-lanterns are carved lanterns, typically made from pumpkins, though historically root vegetables like mangelwurzels, rutabagas, or turnips were used. They are strongly associated with Halloween. The name originates from the flickering lights observed over peat bogs, also called "jack-o'-lanterns." It's also linked to the Irish tale of Stingy Jack, a drunkard who tricked Satan and was cursed to wander the Earth with a hollowed turnip as his only light source.
