Legend has it that citizens of Ireland would wear customs to "trick" the demons away and letting them know they were apart of them on the contrary pumpkins with carved faces begin it was originally said that witches would take skulls and place coals in them to summon spirits and brew up many spells on this special day the story of the Jack o lantern legend has it that jack was a guy who tricked the devil into climbing a tree then carving a cross on it to trick the devil nevertheless the devil asked Jack to let him down and Jack said only if you promise not to take my soul the devil said ok then Jack eventually died he didt make a way to heaven nor he'll so Jack wondered restless in search for a place to rest So is it harmless spirits roaming the night witches brewing up spells casting spells placing curses on people rotting candies ? Yes it is a very demonic holiday but not as merely as demonic as Saturnalia
