25. Shroud of Turin
The Shroud of Turin has a few historians flummoxed while few are still unsure of its origin.
The shroud is a length of linen bearing the negative image of a man; an image which strangely resembles Jesus of Nazareth, as depicted in the Bible.
It is believed that this shroud was used to wrap the body of Christ after his crucifixion.
While carbon dating has placed the age of the shroud much nearer to our times, it was later discovered that parts of the shroud were remade through the ages.
As such, the exact age of the shroud remains unknown.
