Спас Нерукотворный
Such images functioned as powerful relics as well as icons, and their images were naturally seen as especially authoritative as to the true appearance of the subject. Like other icon types believed to be painted from the live subject, such as the Hodegetria (thought to have been painted by Luke the Evangelist), they therefore acted as important references for other images in the tradition. They therefore were copied on an enormous scale, and the belief that such images existed, and authenticated certain facial types, played an important role in the conservatism of iconographic traditions such as the Depiction of Jesus. Beside, and conflated with, the developed legend of the Image of Edessa, was the tale of the Veil of Veronica, whose name was wrongly interpreted in a typical case of popular etymology to mean "true icon" or "true image", the fear of a "false image" remaining strong.
