The shroud is shown in August 2000 at the Cathedral of Turin, Italy.

Rome ? Scientists have reproduced the Shroud of Turin — revered as the cloth that covered Jesus in the tomb — and say the experiment proves the relic was man-made, a group of Italian debunkers claimed Monday.

The shroud bears the figure of a crucified man, and believers say Christ’s image was recorded on the linen at his resurrection.

Scientists have reproduced the shroud using materials and methods that were available in the 14th century, the Italian Committee for Checking Claims on the Paranormal said.

The group said in a statement this is further evidence the shroud is a medieval forgery. In 1988, scientists used radiocarbon dating to determine it was made in the 13th or 14th century.

Lead scientist Luigi Garlaschelli, a professor of chemistry at the University of Pavia, said his team used a linen woven with the same technique as the shroud and artificially aged by heating it in an oven and washing it with water. The cloth was then placed on a student, who wore a mask to reproduce the face, and rubbed with red ochre, a well known pigment at the time. The entire process took a week.
