In an article in The Buffalo News (March 18, 2012), titled, "Debate Over Shroud Continues," reporter Jay Tokasz referred to me as an "investigative historian." I think it is an appropriate label for much of my work on the Shroud of Turin as well as in many other cases, like those in my book Unsolved History (2005. In those I go beyond the usual approach of an historian-perhaps by conducting an experiment, making a scientific analysis, or engaging in other such effort-to actually investigate and solve some historical mystery. My re-creation of the Shroud's quasi-negative image (see photo) is an example. See also Nasca-Geoglyph Re-creator.
