A jack-o'-lantern (or jack o'lantern) is a carved lantern, most commonly made from a pumpkin or a root vegetable such as a rutabaga or turnip. Jack-o'-lanterns are associated with the Halloween holiday. Its name comes from the reported phenomenon of strange lights flickering over peat bogs, called will-o'-the-wisps or jack-o'-lanterns. The name is also tied to the Irish legend of Stingy Jack, a drunkard who bargains with Satan and is doomed to roam the Earth with only a hollowed turnip to light his way. Jack-o'-lanterns carved from pumpkins are a yearly Halloween tradition that developed in the United States when Celtic Americans brought their root vegetable carving tradition with them. It is common to see jack-o'-lanterns used as external and internal decorations prior to and on Halloween. To make a jack-o'-lantern, the top of a pumpkin or turnip is cut off to form a lid, the inside flesh is scooped out, and an image—usually a "scary" or "funny" face—is carved out of the rind to expose the hollow interior. A light source, traditionally a flames from a candle or tealight, is placed within before the lid is closed. Artificial jack-o'-lanterns with electric lights are also marketed. The term jack-o'-lantern was originally used to describe the visual phenomenon ignis fatuus (lit., "foolish fire") known as a will-o'-the-wisp in English folklore. Used especially in East England, its earliest known use dates to the 1660s. The Oxford English Dictionary (OED) records use of the term in Britain from 1658 in reference to ignis fatuus, and from 1663–1704 in reference to a man with a lantern or to a night watchman. The OED gives 1837 as the earliest date for when the term was used to refer to a lantern carved from a turnip or pumpkin. The carving of vegetables has been a common practice in many parts of the world. It is believed that the custom of making jack-o'-lanterns at Halloween time began in the British Isles. In the 19th century, "turnips or mangel wurzels, hollowed out to act as lanterns and often carved with grotesque faces," were used on Halloween in parts of Ireland and the Scottish Highlands.
