☘ Iron was deemed magical because it could withstand fire.
☘ Traditionally, horseshoes were held in place with seven nails, seven being the luckiest number. (Seven days of the week, seven seas, seven continents, and even seven colors in the rainbow)
☘ The horseshoe is only considered lucky if it's actually been worn by a horse.
☘ The ancient Greeks thought the element iron had the ability to ward off evil, and because it took the shape of the crescent moon, was a symbol of good fortune.
☘ In the British Isles in the Middle Ages, when fear of witchcraft was rampant, people attached horseshoes open-end-up on the sides of their houses and doors. People thought witches feared horses, and would shy away from any reminders.
☘ By 1835, a horseshoe manufacturing machine was patented for the first time in the U.S. The machine was capable of producing 60 shoes per hour.
