The Wandering Jew is a mythical immortal man whose legend began to spread in Europe in the 13th century.[1]
The original legend concerns a Jew who taunted Jesus on the way to the Crucifixion and was then cursed to walk the earth until the Second Coming. The exact nature of the wanderer's indiscretion varies in different versions of the tale, as do aspects of his character; sometimes he is said to be a shoemaker or other tradesman, while sometimes he is the doorman at Pontius Pilate's estate.

Wandering Jew, in Christian legend, character doomed to live until the end of the world because he taunted Jesus on the way to the Crucifixion. A reference in John 18:20–22 to an officer who struck Jesus at his arraignment before Annas is sometimes cited as the basis for the legend. The medieval English chronicler Roger of Wendover describes in his Flores historiarum how an archbishop from Greater Armenia, visiting England in 1228, reported that there was in Armenia a man formerly called Cartaphilus who claimed he had been Pontius Pilate’s doorkeeper and had struck Jesus on his way to Calvary, urging him to go faster. Jesus replied, “I go, and you will wait till I return.”

The Fourth Nail was said to be stolen by Gypsies before the crucifixion of Jesus Christ. According to legend, the first and second nails were for Jesus' hands, and the third was for His feet. The fourth was meant to deliver the fatal blow to His heart, but an unwitting Gypsy stole the nail and instead used it to repair his wagon. The Gypsies believed that in return for stealing the item that would have brought instant death upon His son, God would protect their people and forgive them of their petty crimes.
