In January 2011, over two decades after the momentous Nature (1) article dating the Shroud of Turin to between 12, one of the original authors was back on the debate's front lines.
Raymond Rogers says his research and chemical tests show the material used in the 1988 radiocarbon analysis was cut from a medieval patch woven into the shroud to repair fire damage.
It was this material that was responsible for an invalid date being assigned to the original shroud cloth, he argues.
The main aim of this study is to assess - in a reliable non-destructive way and in complementarity to methods already employed or under consideration for future examination campaigns - and to determine some key parameters useful to enhance current knowledge and databases on the textile properties of the Shroud.
Information to be obtained could reveal new interesting and original features with potential scientific and historical effects as well as contributing to solving problems of conservation and preservation.
group published the list of tests to be performed on the shroud; these aimed to identify how the image was impressed onto the cloth, to verify the relic's purported origin, and to identify better-suited conservation methods. We are faced with actual blackmail: unless we accept the conditions imposed by the laboratories, they will start a marketing campaign of accusations against the Church, which they will portray as scared of the truth and enemy of science.
lack of blindness in the measurements is a rather insubstantial reason for disbelieving the result." (t)he Church must respond to the challenge of those who want it to stop the process, who would want us to show that the Church fears the science.
The Shroud of Turin is much older than suggested by radiocarbon dating carried out in the 1980s, according to a new study in a peer-reviewed journal.
A research paper published in Thermochimica Acta suggests the shroud is between 1,300 and 3,000 years old.
Such stains were shown to belong to an MNS positive individual of the AB group, and the halos surrounding the blood stains were compatible with serum containing trace amounts of bilirubin, albumin and immunoglobulins.
