The carved pumpkin, lit by a candle inside, is one of the most prominent symbols of Halloween.
Some trace the Jack-o-lantern to the tale of a man named Jack who tricked Satan into entering a tree, then carved a cross in the trunk, trapping him there until he agreed to leave Jack's soul alone when he died.
The deal backfired when he died - heaven would not take him either. Now Jack wanders for all eternity, with a lit lump of coal in a hallowed-out turnip - or pumpkin.
