The main objective of the inquiry is to deduce the methods and techniques that were
employed in the manufacture of the historically unique Shroud of Turin. By taking a more
or less phenomenologically based stance, it is argued that this image could only have been
produced by employing a photographically related technique. To this end, an examination
is made of both the nature of the image, as well as all relevant documented evidence which
supports the above stated hypothesis. In addition, practical experiments are conducted
which employ the kinds of technology and apparatus known to have existed c 1250-1357
AD. The results of this investigation strongly support the notion that persons living c 1250-
1357 AD did in fact have the necessary technology to manufacture what could be termed
a negative solargraphic image of a human subject.
