Iron nails are associated with superstitions and folk magic. In many cultures, they are believed to have powerful protective properties. Furthermore, they are often used in rituals and spells to ward off evil spirits and negative energy.
One of the most common superstitions surrounding iron nails is to use them to protect a home or property from evil spirits. Therefore, if you drive an iron nail into the doorframe or threshold of your home, it will prevent spirits from entering.
Nails in the doorframe also bring good luck to those who live there. This belief is rooted in the idea that iron is a powerful substance that can repel negative energy and evil spirits.
In Kentucky Superstitions by Daniel Lindsey Thomas, we learn that an iron nail could also be used to make a wish come true by hammering a nail into a piece of wood while making the wish.
Iron nails are also commonly used in folk magic for protection against curses and hexes. For example, if you bury an iron nail in the ground near your home, it will act as a barrier against negative energy and protect you from harm.
Similarly, some believe carrying an iron nail on your person can ward off curses and bring good luck.
Iron nails in literature appear as symbols of protection and strength.
In the Christian Bible, the nails used to crucify Jesus symbolize the sacrifice he made for humanity.
