The James ossuary.
The so-called 'James Ossuary' is a bone box bearing the Aramaic inscription: 'James, son of Joseph, brother of Jesus.'
Dr Witherington says: 'The likelihood of that particular combination of those three names not referring to the famous James the Just, and his father Joseph, and his brother Jesus are slim to none.
'If it were true that the crucifixion was the end of Jesus' story, no one would be bragging about being related to him on an ossuary.'
If the James Ossuary is real, it would indeed be a striking piece of evidence that Jesus was a real figure who became important shortly after his death.
Unfortunately, the story of the James Ossuary is a little more complicated.
The so-called James Ossuary is a box believed to contain the remains of James, the brother of Jesus. However, the box's veracity has been a matter of fierce debate and even legal action
The ossuary was allegedly acquired by an Israeli businessman named Oded Golan from an unknown antique dealer in the 1970s.
However, in an unusual move, the Israel Antiquities Authority (IAA) accused Mr Golan of faking the relic and took him to court in the 'the forgery trial of the century'.
Experts from the IAA alleged that Mr Golan had taken a real first-century ossuary and added the inscription himself.
When police took Mr Golan into custody they did indeed find a forgery lab filled with tools and half-finished 'antiquities'.
But, in another twist, Mr Golan was then acquitted of all charges of forgery in 2012 on the grounds that the IAA had not proven the inscription was fake.
During the trial, it emerged that some of the IAA's experts didn't have the proper specialisms to properly appraise whether or not the writing was real.
For many, this vindicated the James Ossuary as a brilliant piece of evidence for the historicity of Jesus. DM.
