"There's another claim regarding the supernatural qualities of the image of Our Lady of Guadalupe. It is believed it was painted in one step, with no sketches or corrections and no visible brush strokes. And to notice that, infrared light was needed.
For some, it is the most important study, and it is the only scientific study that was duly published shortly after completion.
Some people say NASA (@nasa) scientists conducted the study. That's not accurate. Dr. Philip Serna Callahan was a biophysicist at the University of Florida (@uflorida) who was an expert in infrared photography and an experienced painter, familiar with natural pigments and with Renaissance painting techniques. NASA did not sponsor his study, and he was not a NASA scientist. However, he had previously done work for NASA.
It was May 7, 1979, when the sacred 'tilmàtli' was removed from its glass and metal reliquary, and Callahan was allowed to photograph the image, without touching it, from 9 p.m. to midnight. He took forty photographs, using Kodak (@kodak) High-Speed Infrared Film, for the 0.7 to 0.9 μm infrared range.
Just to put some perspective, the image on that tilmàtli is the reason this area is the most visited Catholic pilgrimage site in the world, attracting more than 20 million visitors every year. That's even more than the Vatican itself. And those pilgrims can only see the tilmàtli inside a massive frame, protected behind bullet-proof glass, and a mechanism that retracts it into a vault set in the wall. It is considered one of the great masterpieces of artistic facial expression, dating back to the year 1531, and on top of that, it is believed to have been created as a result of one of the only twelve Marian apparitions officially approved by the Roman Catholic Church.
And there it was, laid bare in front of Dr. Callahan." - Comrade (the human)
