Oh, I'm a Christian. But these things tend to become items of worship and veneration. So, on a spiritual level, I tend to consider them meaningless.
However, on a historical or scientific level, maybe there's something there. I just don't know. Why this one shroud of all the thousands over the centuries? Are there others that exhibit this?
It may be genuine. It may not. There's no first hand testimony either way, and likely can't ever be. Even if someone found something supposedly written, it would still be suspect.
So, yeah, very fascinating. Pretty cool, actually. It can promote our imaginations. But I'd be slow to make more of it.
Thanks for your work on it. Well done.
