where does the jack o lantern name come from
Jack-o'-lantern 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.[3] The term "will-o'-the-wisp" uses "wisp" (a bundle of sticks or paper sometimes used as a torch) and the proper name "Will": thus, "Will-of-the-torch." The term jack o'lantern is of the same construction: "Jack of [the] lantern."
Jack-in-the-box A theory as to the origin of the jack-in-the-box is that it comes from the 14th century English prelate Sir John Schorne,[3] who is often pictured holding a boot with a devil in it. According to folklore, he once cast the devil into a boot to protect the village of North Marston in Buckinghamshire. In French, a jack-in-the-box is called a "diable en boÃ®te" (literally "boxed devil").
