Fascinating stuff here:
The face in the Shroud
A computer graphic shows Jesus’ body underneath the Shroud of Turin, as
reconstructed for “The Real Face of Jesus,” airing on the History Channel.
Does the Shroud of Turin show the “real face of Jesus”? That claim is impossible to judge, even though it serves the title of a documentary about the 3-D analysis of the Shroud of Turin premiering tonight on the History Channel. What can be said is that the centuries-old image wasn’t just painted freehand. Computer analysis of the imprint on the shroud suggests that it had to be left behind by someone draped in cloth.
“Is this the artifact of a real person or not? Definitely it is,” Ray Downing, the digital illustrator at the center of the show, told me today.
Downing worked with specialists on the shroud to come up with a photorealistic representation of the man whose body’s imprint appears faintly on a famous 14-foot-long length of linen. For some Christians, the stain serves as the miraculous snapshot of their risen Lord. For most scientists, it is a cleverly done fake from the 13th or 14th century, but nothing more.

Back in 1988, carbon-14 dating tests were conducted on a sample from the shroud in an effort to determine whether the cloth was created in Jesus’ time. The verdict from three laboratories was that the cloth was produced in medieval times. But the shroud’s fans have insisted that the sample was actually taken from a patch, rather than from the original linen. Just this month, a chemist proposed a new series of non-destructive dating tests that would give an estimate for the entire cloth. [This would be interesting. But wasn’t there some controversy about with concerning a preservation technique that altered the shourd?]
From a marketing perspective, the timing of the History Channel show couldn’t be better: Good Friday and Easter Sunday, the Christian holy days that mark Jesus’ death and resurrection, are just a few days away. What’s more, the shroud is due to go on display for six weeks at Turin Cathedral, starting April 10. The last time the relic was exhibited, a decade ago, more than 3 million people came to Turin to see it. More than a million reservations have been received already for next month’s viewing.
Have scientists been wrong about the shroud? Downing noted that historical records referring to the shroud predate the current carbon-14 estimate. “We know the carbon-14 [test] is wrong,” he said. “The question is, how wrong are they? The further back you go, the less likely it is that anybody could have faked it.”
Digital illustrator/animator Ray Downing and John Jackson look at a high-quality
replica of the Shroud of Turin, displayed at Jackson’s research center in Colorado.
But the dating debate isn’t the focus of Downing’s work: Rather, he concentrated on what the shroud shows. Could the faint outlines preserved in the cloth match up with the outlines of a specific person? Downing found that they could, and he drew up a 3-D image that fit the data.
“It’s just like how a police investigator will question an eyewitness, and from that information he can draw a complete sketch,” Downing said. “The shroud is a silent witness. It’s like the witness in an investigation.”
Downing started out with high-resolution photographs of the shroud from the Holy Shroud Guild and the Shroud of Turin Research Project. “Between the two of them we were able to come up with a good image,” he said.
He also consulted with John Jackson, a physicist who has come to specialize in studying the shroud at his research center in Colorado. Once all the imagery was computerized, Downing used software to massage the 2-D data into 3-D imagery.

imprint seen on the Shroud of Turin. The imagery was used to develop 3-D models.
3-D visualizations of the face in the shroud have been done before, but Downing found that the data couldn’t be matched up with a realistic representation if he just added another dimension to the shroud’s flat plane. The image looked more like a reflection in a funhouse mirror – and that’s because the cloth had to be draped around the body’s form to produce a match.
Downing said the cloth “encoded” the 3-D data on a 2-D surface. “It’s as if there is an instruction set inside a picture for building a sculpture,” he explained in a news release.
By manipulating the computer model, Downing matched up the shroud’s imprint with anatomical features drawn from more than 100 human scans. “The nose might have come from here, the nostrils from there,” he told me. The result is a realistic illustration, based on the data encoded in the shroud.
History Channel / Ray Downing
Illustrator Ray Downing tweaked graphic representations of human models to come
up with a realistic 3-D image of the person whose imprint is on the Shroud of Turin.
Downing said the depiction shown in the History Channel program represents his best effort to put flesh and bones on the shroud’s imprint – and he would argue that it’s the best effort anyone has made. “This is the closest one, anatomically,” he said.
Over the years, not everyone has agreed that the shroud can fit a realistic form. Joe Nickell, a paranormal investigator for Skeptical Inquirer magazine, told an interviewer a decade ago that if the draping effect is taken into account, the body beneath the shroud would have to have been “unusually narrow … so very long and narrow that one pro-Shroud pathologist suggested that Jesus must have had Marfan’s syndrome.” [Is it possible that the violence that Jesus endured during His Passion caused such severe stress on His body so as to deform it? Couldn’t all the scourging, beatings, etc. coupled with gravity cause elongation of muscle tissue, essentially stretching Our Blessed Lord thus accounting for an unnatural/abnormal elongation?]
If Downing’s analysis played it straight, the shape beneath the shroud is at least plausibly human. But is it Jesus? [Regardless, that has always been a question to the faithful.] Or some anonymous person from the first or the 13th century? Feel free to weigh in with your comments below, before or after the show airs.
Update for 8:18 p.m. ET March 30: In a follow-up telephone interview, Skeptical Inquirer’s Joe Nickell noted that questions have surrounded the Shroud of Turin since the 14th century, when it showed up in France. Nickell suggests that the shroud could have been forged by applying a red ochre pigment to the linen, then modeling it on a body with a bas-relief mask over the face.
Nickell said an Italian chemist, Luigi Garlaschelli, used the recipe to create a shroudlike replica. [As far as I know this has been refuted.] “He made a ‘shroud’ using the theories of mine that I told you, then artificially aged it by baking, and then he washed it to remove the pigment – and voila! There was the yellow stain,” Nickell said. The effect was similar to the effect seen on the Shroud of Turin.
“There are two approaches to this,” Nickell told me. “There’s ordinary science, and then there’s what I call shroud science. Ordinary science starts with evidence, and lets the evidence lead wherever it will. This is the approach used by a ‘CSI’ team. Shroud science is quite different, and it starts with the answer. They start by saying, ‘This is the shroud of our Lord,’ and then they take whatever steps they need to get to that answer.” [I think most Catholics would agree that investigations are done from a skeptical point of view. Canonization, apparitions, miracles, etc. are always seen with a skeptical eye first. The Church often moves prudently slow in these matters.]
Nickell is skeptical … not only about the Shroud of Turin, but also about the prospects for settling the shroud debate to everyone’s satisfaction. [“For those who believe, no proof is necessary. For those who don’t believe, no proof is possible.” – Stuart Chase]
“Shroud science is backward from ordinary science,” he said. “It’s very discouraging to me that the media have been so willing to give it a pass.” [The media usually never gives anything related to God a pass. Often it may use goodhearted approaches to make backhanded comments.]
Update for 2:50 p.m. ET March 31: I’ve been wading through thousands of comments on this item – an exercise that has revealed once again how fallible mortals (and software) can be. I apologize to those whose messages I have not approved, either because I just couldn’t get to them or because they struck a slightly wrong or redundant chord. I also apologize to those who may take offense at some of the messages that were approved. Thanks to all of you who wrote in – and whether you’re Christian or Jew, Muslim or Buddhist, of some other faith or of no religious faith at all, have an uplifting week!

Looks like I am going to DVR something tonight!
Here is a devotional prayer for the Holy Face of Jesus:
Prayer of St. Theresa of the Child Jesus and the Holy Face
O Jesus, who in Thy bitter Passion didst become “the most abject of men, a man of sorrows”, I venerate Thy Sacred Face whereon there once did shine the beauty and sweetness of the Godhead; but now it has become for me as if it were the face of a leper! Nevertheless, under those disfigured features, I recognize Thy infinite Love and I am consumed with the desire to love Thee and make Thee loved by all men.
The tears which well up abundantly in Thy sacred eyes appear to me as so many precious pearls that I love to gather up, in order to purchase the souls of poor sinners by means of their infinite value. O Jesus, whose adorable face ravishes my heart, I implore Thee to fix deep within me Thy divine image and to set me on fire with Thy Love, that I may be found worthy to come to the contemplation of Thy glorious Face in Heaven. Amen.
