Спас Нерукотворный
Such beliefs clearly projected contemporary practices back to the 1st century, and in their developed form are not found before the lead-up to the Iconoclastic Controversy, but in the 4th century, Eusebius, who disapproved of images, accepted that "the features of His apostles Peter and Paul, and indeed of Christ himself, have been preserved in coloured portraits which I have examined". Many famous images, including the Image of Edessa and Hodegetria, were described in versions of their stories as this type of image. The belief that images presumably of the 6th century at the earliest were authentic products of the 1st century distorted any sense of stylistic anachronism, making it easier for further images to be accepted, just as the belief in acheiropoieta, which must have reflected a divine standard of realism and accuracy, distorted early medieval perceptions of what degree of realism was possible in art, accounting for the praise very frequently given to images for their realism, when to modern eyes the surviving corpus has little of this. The standard depictions of both the features of the leading New Testament figures, and the iconography of key narrative scenes, seemed to have their authenticity confirmed by images believed to have been created either by direct witnesses or those able to hear the accounts of witnesses, or alternatively God himself or his angels.
