imageOnly Adler [pictured to the right] carried out any such study, and this is what he said: “Interestingly, fibrils freed of their coatings using this technique [protease to dissolve away any protein] closely resemble the non-image fibrils of the Shroud.” I cannot take this as a general truth. All the Mark Evans photos showing bloodstains clearly show that most of the red particles have been rubbed off the upper surfaces of the threads, and are mostly confined to the cracks and crevices where one thread crosses another. The surfaces from which the blood has been rubbed off are as yellow as the rest of the image fibres, and do not carry the distinctive silky white appearance of the non-image threads.
