Why an Atheist Thinks the Shroud of Turin is the Real Deal

Ian Wilson

Back in his laboratory in Zurich, Frei surveyed the dust he had collected under the microscope. His trained eye immediately identified mineral particles, fragments from hairs and fibers of plants, spores from bacteria and nonflowering plants such as mosses and fungi, and pollen grains from flowering plants-all consistent with the sort of microscopic debris the Shroud could be ex-pected to have accumulated over the centuries. Being chiefly a botanist by training, Frei found the pollen to be of the greatest interest. As he was aware, pollen grains have an extremely resistant outer wall, the exine. Although so small as to be virtually invisible to the naked eye, these grains can and do retain their physical characteristics for literally hundreds of millions of years, being immune to almost any form of destruction. As Frei was also aware, when viewed under the [scanning] electron microscope pollen grains vary so considerably in physical characteristics that, thanks to careful classification of the different types over the years, it is possible to identify with certainty the pre-cise genus of plant from which any grain has been de-rived. Frei realized that identification of the plants from which the pollen on the Shroud had been derived could lead to important deductions about the geographical regions in which the Shroud had been.
