Stingy Jack is a figure from Irish folklore known for his cleverness and trickery. According to legend, he was a deceitful man who tricked the devil into not taking his soul. After his death, both heaven and hell rejected him, leaving him to wander the earth with only a carved turnip to light his way. The story of Stingy Jack is often associated with the celebration of Halloween. People began to carve faces into turnips and other vegetables to create lanterns, which eventually evolved into the modern jack-o'-lantern made from pumpkins. This tradition symbolizes the guiding light for lost souls.
