This essay divulges what the research has established about the famous Shroud of Turin, and it is not intended to persuade to believe that the Cloth of Turin really wrapped the body of Christ a couple of thousands year ago. The author returns several times to certain subjects, according to different perspectives: the reader does not consider such reiterations as not necessary and involuntary: the work includes a general introductory part - at some point, considering it useful, already with in-depth studies, as for the medical conclusions of the anatomopathologist Pierluigi Baima Bollone - and a section, divided into chapters, specifically dealing with particular topics already covered in the first part, for example the photographs of the Shroud, and a chronology.
