The Helmet of Constantine was a form of helmet worn by the Roman Emperor Constantine the Great, now lost, which featured in his imperial iconography. According to a story recorded by Ambrose and others, it included relics gathered in the Holy Land by his mother, Empress Helena. Constantine's conversion to Christianity, which happened around AD 300, was of great importance. In this period it was believed that touching the body of the deceased or even something that came in contact with the person who had died was said to have special powers. This belief started a movement to find these relics to protect churches, cities, and even people. History At the time, Constantine I was thought to be protected due to the relic in his possession. The helmet that he wore was said to have a piece of the True Cross that Jesus was crucified on. After Constantine was made Caesar, he issued the Edict of Milan (313), sending his mother Helena to find the True Cross and to send back what she found. Helena found the cross and sent three nails that were used in the crucifixion of Jesus back to Rome and her son Constantine. The helmet that Constantine wore included one of the Holy Nails that Saint Helena found at the crucifixion site. By making the helmet with one of the nails, it was supposed to protect him from any harm. Not only was it a sign of protection, but it was also said to fulfil the prophecy of Zechariah. The prophecy located in the fourteenth chapter of the Book of Zechariah said that one would come who engraved “Holiness to the Lord” on both the bells of the horses and headpiece of the man. At this time, the Roman emperor had the holiest relics known to man. A rare silver medallion dated 315 AD shows Constantine with a chi-rho symbol as the crest of his helmet, and Eusebius' Life of Constantine records that he often wore such a helmet in later life, although it is not visible in other bronze coins. Constantine was very aware of this, and let the entire Roman Empire know that he was the owner of this holy helmet. The emperor had coins made with the image of him wearing his helmet on the front. On every VLLP coin that was made, Constantine was shown wearing his helmet. This was one way
