Is the Shroud of Turin really just 18 years short of its 2000th birthday? SEE THIS BLOG FOR A DAILY ACERBIC OVERVIEW OF CURRENT WRANGLING (currently 2015, now Week 35)

Site banner: see how a simulated sweat imprint (my wet hand pressed down onto dark fabric) responds magnificently to 3D-rendering computer software (ImageJ) before and after tone-reversal (negative back to positive image).

Time maybe for a radical re-jigging of the scorch model – and of the alleged superficiality of the Shroud image too?

I’ve been exchanging emails with Hugh Farey recently. He’s been sending some impressive photographs of linen fibres,  before and after scorching. There’s currently the  beginnings of an exchange of views on the importance or otherwise of the primary cell wall … Continue reading
