The earliest non-biblical testimony of Jesus from the  writings of Jewish writer Flavius Josephus (37-100 AD)

 “At that time also there appeared a certain man of magic power!… if it be meet to call him a man, [whose name is Jesus], … he was a man of simple appearance, mature age, black-skinned,  short growth, three cubits tall, hunchbacked,   ‘with a long face’ , a long nose, eyebrows meeting above the nose … with scanty [curly] hair, but having a line in the middle of the head after the fashion of the Nazaraeans, with an undeveloped beard.”source

If it was created, it must have been done by someone with extraordinary skills. The evidence points to one man, one of the greatest geniuses who has ever lived-Leonardo da Vinci. The fabric could have been hung over a frame in a blacked-out room and coated it with silver sulfate, a substance readily available in 15th century in Italy which would have made it light-sensitive. When the sun’s rays passed through a lens in one of the walls, da Vinci’s facial shape would have been projected on to the material, creating a permanent image!
