"Funny, he's got the marks of a phylactery on his forehead. That looks distinctly Jewish." Well, I learn a new word every day. Thanks.
Phylactery: "Judaism. Either of two small leather boxes, each containing strips of parchment inscribed with quotations from the Hebrew Scriptures, one of which is strapped to the forehead and the other to the left arm; traditionally worn by Jewish men during morning worship, except on the Sabbath and holidays."
Wikipedia on Teffilin / phylacteries
Wikipedia quotes Old Testament verses and says ancient phylacteries were found at Qumran, so I'll take that as being plenty ancient enough.
Still, you'd suppose the New Testament would mention such a matter, especially as it carefully points out the dramatic crown of thorns, blood from which is said to appear on the Shroud of Turin.
Funny, he doesn't look Jewish.
What did a Jew look like 2000 years ago? The Shroud image shows a man who has been severely beaten and crowned with thorns. Here is a medical description of the Roman crucifixions.
Preparations for the scourging are carried out. The prisoner is stripped of His clothing and His hands tied to a post above His head. It is doubtful whether the Romans made any attempt to follow the Jewish law in this matter of scourging. The Jews had an ancient law prohibiting more than forty lashes. The Pharisees, always making sure that the law was strictly kept, insisted that only thirty-nine lashes be given. (In case of a miscount, they were sure of remaining within the law.) The Roman legionnaire steps forward with the flagrum (or flagellum) in his hand. This is a short whip consisting of several heavy, leather thongs with two small balls of lead attached near the ends of each. The heavy whip is brought down with full force again and again across Jesus' shoulders, back, and legs. At first the heavy thongs cut through the skin only. Then, as the blows continue, they cut deeper into the subcutaneous tissues, producing first an oozing of blood from the capillaries and veins of the skin, and finally spurting arterial bleeding from vessels in the underlying muscles. The small balls of lead first produce large, deep bruises which are broken open by subsequent blows. Finally the skin of the back is hanging in long ribbons and the entire area is an unrecognizable mass of torn, bleeding tissue. When it is determined by the centurion in charge that the prisoner is near death, the beating is finally stopped.
The Passion of Christ from a Medical Point of View
Naturally, the crucified man's face was swollen from flagellation and torture.
