We’ve waded through piles of mail that wasn’t forwarded, done a ton of laundry, and caught up with family and friends (though our blog and regular email access made this possible on the road). Though they’ve all been mentioned in the blog, we wanted to list a few companies and people who made this trip much more enjoyable and successful.

Scholars debate its existence previous to 1390, describing the period before that as “very murky territory.” Even during the middle ages there was disagreement over authenticity of the cloth, with written claims at the time between church officials suggesting it was a forgery.However, historians raise the possibility that several such ‘shrouds’ were making the rounds at the time, and forgery claims might have had nothing to do with the cloth found today in the cathedral in Turin, Italy.Rowe's new method eliminates the destructive steps of sampling, acid-base washes and burning.The object is simply placed in a special chamber with a plasma, an electrically charged gas similar to that used in big-screen plasma television displays.According to Fanti, both the infrared light beam and the red laser of the Raman spectroscope excite the molecules of the material, and the resulting reflections make it possible “to evaluate the concentration of particular substances contained in the cellulose of the linen fibers.” Because cellulose degrades over time, he said, “it is therefore possible to determine a correlation with the age of the fabric.” Fanti compared his results with nine other ancient textiles of known provenance, with ages from 3000 B. The shroud’s official custodian, Archbishop Cesare Nosiglia of Turin, told “There is no degree of safety on the authenticity of the materials on which these experiments were carried out [on] the shroud cloth.” Responded Fanti, “He did not read my book, and especially its appendix in which the traceability of the samples is clearly shown.” According to Fanti, Riggi unstitched the backing cloth that was sewn onto the shroud in 1532 to protect it after it was damaged in a fire and vacuumed some of the dust that had accumulated between the two sheets, catching this residue on a series of filters.It was on fibers from “filter H” that Fanti did most of his work.“I discovered a relatively simple technique to detect which linen fibers were from the shroud,” he said, “based on cross-polarized light used in a petrographic microscope.

All living things have the same ratio of stable carbon to radioactive carbon-14, but after death, the radioactive carbon decays in a predictable pattern over time.Conventional carbon dating estimates the age of an artifact based on the decay rate of the radioactive isotope carbon-14, a variant of carbon that is incorporated in all living organisms.Any material of plant or animal origin, including textiles, wood, bones and leather, can be dated by its content of carbon-14.Scientists typically remove a small sample from an object, treat the sample with a strong acid and a strong base, and then burn it in a small glass chamber to produce carbon dioxide gas.Comparing the carbon-14 levels in the object to those expected in the atmosphere for a particular period in history allows scientists to estimate the age of an artifact. ► The Differences Among Clairvoyants, Psychics, and Mediums ► The Psychic Eye ► Linda and Terry Jamison: The Psychic Twins The mystery that has always surrounded the Shroud of Turin might as well be a riddle because although it was pronounced as a forgery in 1988 by results of carbon dating, there has been no rational explanation to date of how the ghostly image on the cloth came to be there.
