“Artifacts and symbols associated with Halloween formed over time. Jack-O’-Lanterns are traditionally carried by guisers on All Hallows’ Eve in order to frighten evil spirits. There is a popular Irish Christian folktale associated with the jack-o’-lantern, which in folklore is said to represent a “soul who has been denied entry into both heaven and hell”:On route home after a night’s drinking, Jack encounters the Devil and tricks him into climbing a tree. A quick-thinking Jack etches the sign of the cross into the bark, thus trapping the Devil. Jack strikes a bargain that Satan can never claim his soul. After a life of sin, drink, and mendacity, Jack is refused entry to heaven when he dies. Keeping his promise, the Devil refuses to let Jack into hell and throws a live coal straight from the fires of hell at him. It was a cold night, so Jack places the coal in a hollowed out turnip to stop it from going out, since which time Jack and his lantern have been roaming looking for a place to rest.” – reprinted DIRECTLY from my favorite auto mechanic – Ernie’s Garage !
