Picknett and Prince Fallacy

This page is best understood by first reading the page, How Tall is the Man on the Shroud?
 
Picknett and Prince (simple assumed face ratio) 6'8" - 6'10"
Isabel Piczek, artist specializing in human anatomy. 5'11½" - 6'1"
Fanti, Marinelli, Cagnazzo (tibio-femoral indices calculations) 5'8" - 5'9"

Luigi Gedda (sagittal plane of face applied to anthropometric ratio)

6'0"
Picknett and Prince (corrected for logical fallacy) 5'9" - 6'1"

Lynn Picknett and Clive Prince in their book, Turin Shroud - In Whose Image, wrote:

Our calculations put the height of the man on the Shroud - at the front - at 203cm...Put in imperial measurements we calculate that the front image is 6ft 8in and the back 6ft 10in.

They arrived at this height by assuming that the head height to body height ratio on the shroud was 1 to 9 rather than the average 1 to 8. So they multiplied their height of the head measurement by nine. The problem:

  • This is profoundly illogical. Without knowing the height of the body first, how can one arrive at a ratio?
     

  • It is very difficult to measure the height of the head. We don't know the angle of the head, how collimated it is to the image plane or how distorted it may be (in a Mercator projection concept).

Nonetheless, using Picknett and Prince's estimate for the head and correcting it to the 1 to 8 ratio (which is admittedly only an average) the height of the man on the shroud is 6 ft 0 in.
