A doctor who is now a priest has put forward a new theory about the death of Jesus.
Some might be wondering if this is actually a mystery at all, as Mirror sources report that there is actually a very good book about the supposed event known as the Holy Bible, but there are some questions about the account contained within.
The tradition of Good Friday and Easter relates to Jesus' death and much of what we know about his demise comes from the gospels in the New Testament.
Crucifixion, the act of being tied or nailed to a cross, is famously how Jesus met his fate, but one scientist now believed the fatal moment actually happened before the Roman nails pierced his skin.
How did Jesus die?
Reverend Professor Patrick Pullicino has written a scientific paper that claims Jesus may have actually died from complications from a dislocated shoulder.
According to the tales from the time, Jesus fell when he was made to carry his heavy cross up to the hill known as Calvary in Jerusalem, where he died.
Pullicino, a former consultant neurologist at East Kent University Hospitals NHS Trust, argues that testimony of what occurred after Jesus' death proves his theory, as reported by The Telegraph.
Throughout history, paintings of Jesus on the cross show a stab wound in his side, from a Roman soldier who confirmed Jesus was dead when blood and water flowed out from the wound.
The reverend professor argues this must have occurred as the cavity between the ribcage and lung had been filled with blood when Jesus' dislocated right shoulder ruptured an artery.
The famous Turin Shroud, claimed to be the sheet used to wrap Jesus' body, is the basis for Pullicino's study.
Carbon testing in the 1980s believed the shroud is from the medieval period, while a 2010 claim disputes this and says it was from the time of Jesus.
The imprint of the man on the shroud, Pullicino says, has a dislocated shoulder.
Was Jesus real?
The short answer to whether a person called Jesus existed around 2,000 years ago is 'we don't know', or 'it depends on who you believe'.
Outside of religion, there is an argument based on some historical evidence that a person called Jesus did exist in the same period and was written about, but this is heavily disputed.
However, there aren't any eyewitness accounts of Jesus outside of the Bible.
Bible accounts, such as the letters known as the epistles, claim to be evidence as they are believed to be written around 25-40 years after Jesus' death.
They have adequate descriptions of what life was like in 1st century Palestine and the argument is that Christian followers from the time are unlikely to have made up a savour who was Jewish.
However, they describe the non-historical Jesus, or the man able to walk on water, so even this evidence is disputed.
Jewish historian Flavius Josephus wrote a history of Judaism in AD93 and has two references to a man called Jesus. However, some think that these writings were seized and changed by Christians, though one part of the text refers to a man named James, the brother of “Jesus, the so-called Christ”, and is not believed to have been changed.
There are more Roman writings that suggests a man named Jesus was executed at the time Pontius Pilate was in charge of Judaea, where Jerusalem was.
But other historians and philosophers argue there are too few sources to claim for certain he existed.
