There are certain historical problems, of which the Turin Shroud is one, in which there is 'fantastic fascination' with the topic, but a historical vacuum - a lack of solid evidence - and where there's a vacuum - nature abhores a vacuum - and historical speculation abhors a vacuum - and it all floods in... But what you end up with is almost nothing tangible or solid. You start from a hypothesis, and then that is deemed to be demonstrated more-or-less by stating the speculation, you then put another speculation on top of that, and you end up with this great tower of hypotheses and speculations - and if you say 'where are the rocks underneath this?' they are not there. It's like the House on Sand, it washes away as soon as you ask really hard questions of it.
