In 1988 radiocarbon dating of the Shroud of Turin found that the relic many faithful believe to be the burial linen of Christ originated about 700 years ago. While the study suggested the shroud was not authentic, it has done little to abate the faith of those thousands who make pilgrimage to Turin to venerate the relic. Now, a new dating technology has placed the fabric within the time of Christ.
WAXS
The study was conducted by Dr. Liberato de Caro of Italy’s Institute of Crystallography of the National Research Council, in Bari. Dr. de Caro has employed a method known as “Wide-Angle X-ray Scattering,” or WAXS, which measures the natural aging of flax cellulose and converts it to time since manufacture.
The process has several key features that make it more desirable than radiocarbon dating, not least of which that it is completely non-destructive to the samples. Furthermore, the size of the sample required for WAXS is much smaller, requiring just a portion of cloth approximately 0.5mm x 1mm.
Carbon-14 inadequacy
In his report, published on the website of Italy’s Department of Chemical Sciences and Materials Technologies, de Caro pointed out a few flaws with dating by Carbon-14 analysis. He noted that textile samples can easily become contaminated with substances that could skew its results. He wrote:
De Caro noted that fabric can even become enriched with new Carbon-14 samples. At this point, it would become hard to identify if carbon dating measured the original fabric, or a layer of carbon that was accumulated over time.
WAXS Dating
De Caro explained that the WAXS method was used on a variety of samples of historical textiles that have been documented to be aged from 3000 BC to 2000 AD. He placed the Shroud of Turin against these samples and found that it best matched a piece of fabric known to have come from the siege of Masada, Israel, in 55-74 AD.
If accurate, the findings would suggest that the shroud originated around the time of Christ, and this could mean it was indeed Jesus’ burial cloth. Still, de Caro has advised caution, as the new date contrasts the Carbon-14 dating by such a large margin.
Dr. de Caro suggested that the WAXS analysis should be performed by other laboratories in order to confirm the findings. In an interview with National Catholic Register, he said:
Pollen
De Caro also noted some exciting elements that could help trace the shroud’s history and migration from the Middle East to Europe. He noted that the samples of the shroud contained samples of pollen from the ancient region of Palestine, which could not have originated in Europe. This factor alone suggests that the Shroud of Turin spent extensive time in the Middle East.
