FILE – In this Aug. 12, 2000 file photo, The Holy Shroud, a 14 foot-long linen revered by some as the burial cloth of Jesus, is shown at the Cathedral of Turin, Italy. A Vatican researcher claims a nearly invisible text on the Shroud of Turin proves the authenticity of the artifact revered as Jesus burial cloth. The claim made in a new book by historian Barbara Frale drew immediate skepticism from some scientists, who maintain the shroud is a medieval forgery. Frale, a researcher at the Vatican archives, said Friday that she used computers to enhance images of faintly written words in Greek, Latin and Aramaic scattered across the shroud.
