Turin shroud

they must have had some talent to produce the image

If it was with silver nitrate it would work like a photographic image - you paint it on in the dark then expose it to the view you want to picture. Not easy to use, but my money is on Leonardo Da Vinci - right era, right enquiring mindset and interest in the latest scientific knowledge, right artistic ability. I don't think he mentioned it in his notebooks though - anyone finding a reference to that would have gone public with it by now.

As far as I know it has been proved quite conclusively and scientifically that the Turin shroud is a medieval/post medieval fake. I write as a catholic before someone tells me 'but catholics believe it is the true shroud'. No, most of us don't.

I've read several books about the Shroud, it's a fascinating mystery. The only definitive scientific agreement is that it's mediaeval not c2000 years old.

There was a TV programme some time ago. They tested the fabric, and that was made in medieval times. There is still no definitive answer to how the image was put on. There doesn't seem to be any trace of pigment.

I hope that it remains a mystery personally

It is such a moving image I would like to very it to be genuine, but the evid nice to the contrary is overwhelming.
But even as a medieval artefact it is quite amazing.

Like Fllickety I thought it was well established as being a fake.

Yes, sadly. I wish they hadn't investigated it so thoroughly, too. It was a few years ago now. However, someone else is now trying to claim that the scientific evidence was wrong, that the shroud was indeed from the time of Christ, and has reopened the debate.

"I would very much like it" etc
Do these bl**dy iPads have a mind of their own?

Yep!
