You might enjoy doing some homework before the program - if you aren't already familiar with the history and evidence concerning The Shroud.
As a portrait artist, I have studied The Shroud, for over 40 years, from the art angle. The many iconic paintings that were done for the churches, pre-dating what many would like to think about The Shroud, provide a strong testament. (Many iconic paintings were ordered destroyed, but many escaped.)
My favorite is the 6th Century Pantocrator. Here are some great links to start with:
(Remember - the painting was done in the 500’s)
and this is Barrie Schwortz’s Shroud Web site. He was one of the original examiners in 1978. I have corresponded with him for years. He started out as a skeptic.
As well as the way it has been presented of comparing the Shroud of Turin to the original image of Divine Mercy. There use to be a website that had it superimposed so you could see it right on top, I can’t find it now.
This webpage does have it at the bottom of the article: http://www.faustina-message.com/zgromadzenie_anga.htm
I think some of us too are vaguely or well familiar with the Shrouds influence on early icons.
Back to the Divine Mercy, the original illustration is the important one here and if there is such a thing as Divine Inspiration, that may be a part of it.
Thanks for the link.
