A new DNA analysis of the Shroud of Turin, the ancient linen cloth believed by many Christians to have wrapped the body of Jesus after his crucifixion, has uncovered fresh biological clues that researchers say add another layer to the centuries-old debate over the relic’s origins.
Scientists examining fibres taken from the mysterious 14-foot cloth detected a rare human genetic lineage associated with the Near East, the region where Jesus lived, while also identifying microorganisms linked to highly saline environments.
The findings have renewed discussions about whether the Shroud’s history connects to the Middle East and the biblical account surrounding Jesus’ burial.
However, researchers stressed that the DNA evidence does not prove that the cloth belonged to Jesus Christ or confirm that it was the garment used after his crucifixion.
The Shroud of Turin, housed at the Cathedral of Saint John the Baptist in Turin, Italy, has remained one of the most studied and controversial religious artefacts in history.
The linen carries the faint image of a man, which believers say represents Jesus after his resurrection, while sceptics have questioned its authenticity for decades.
The latest study, published in Scientific Reports, analysed separate fibre samples collected during a 1978 investigation using advanced DNA sequencing technology capable of detecting millions of genetic fragments.
Researchers led by Dr Gianni Barcaccia, professor of genetics and genomics at the University of Padua, examined biological traces left on the cloth during its long and disputed journey.
The team detected a human mitochondrial DNA lineage known as H33, which is found mainly among Near Eastern populations, including the Druze communities of the Holy Land, Jordan, Lebanon and Syria.
Researchers said the discovery was consistent with previous findings suggesting the Shroud of Turin had passed through the Middle East, though they noted it cannot establish who originally touched or was wrapped in the cloth.
The analysis also identified salt-loving microorganisms known as archaea, which are associated with highly saline environments.
The researchers said the findings raised the possibility that the cloth had encountered salty conditions during storage or processing, although they could not determine exactly where or when those traces appeared.
Previous scientific examinations have produced conflicting conclusions about the Shroud’s age.
Radiocarbon testing carried out in the 1980s suggested the linen originated from the medieval period, but supporters of its authenticity have argued that contamination, repairs and handling may have affected those results.
The new DNA study also found evidence of centuries of human contact, including skin bacteria, fungi, plants and animal material from different parts of the world.
Researchers detected biological traces linked to Europe, Asia, the Mediterranean and other regions, showing that the cloth had been exposed to numerous environments throughout history.
Some plant material found on the Shroud was linked to species that became common in Europe centuries after the time of Jesus, further complicating efforts to determine its exact origin.
The scientists concluded that while the findings provide new information about the Shroud’s history and possible geographical connections, they cannot determine whether the linen dates back to the first century or whether it was connected to Jesus.
The discovery has nevertheless reignited one of history’s most enduring debates – whether the mysterious image preserved on the Shroud of Turin is linked to the crucifixion and resurrection story central to Christianity.
